Analysis of the five elements that need to be met in injection molding

Plastic molding is the process of making various forms (powders, pellets, solutions and dispersion) of plastics into products or blanks in the desired shape.The manufacturing process of most cosmetic packaging materials is mainly through the four key processes of mold molding, surface treatment,printing,and assembly.The molding process is an indispensable key part.Injection molding is a method of producing shapes for industrial products.Products usually use rubber injection molding and plastic injection molding.Injection molding can also be divided into injection molding compression method and die-casting method.Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes. Injection molding is realized by injection molding machines and molds.

The five elements that need to be met in injection molding are:

Temperature: Temperature is the first step of injection molding.Temperature can be divided into:drying temperature,material temperature,mold temperature, these are some of the most important factors.The drying temperature is to dry the polymer in advance in order to ensure the quality of the molding,to ensure that the dry and wet of the polymer are within a certain amount;The material temperature is to ensure that the polymer is plasticized normally,and the mold is filled and formed smoothly;

Speed: Speed is divided into:injection speed,Melting speed,loosening and retreating speed,opening and closing mold speed,thimble forward and backward speed.The increase of the injection speed will affect the increase of the filling pressure,and the increase of the injection speed can increase the flow length,and the product quality can be uniform to ensure the quality of the product.High-speed injection is suitable for long-process products,and the size of the product is controlled at low speed;Melting speed affects plasticizing ability,plastic mold processing is an important parameter of plasticizing quality,the higher the speed,the higher the melt temperature,the stronger the plasticizing ability;

Pressure: Pressure is divided into: injection pressure,holding pressure, back pressure,clamping pressure,mold protection pressure,ejection pressure.

Position: The position can be divided into:mold opening position, ejection retreat stroke,metering stroke,leg loosening amount,injection stroke,and buffering amount.The mold opening position is to ensure the normal operation of the demolding parts.The effect of the ejection back stroke on the partial spring return to the ejection limit protection.The metering stroke is to ensure that there is enough plastic to fill the mold to ensure product quality.

Time: The time is divided into:cooling time,sol time,drying time, cooling time,melting time,drying time,cycle,injection time,and pressure holding time.The molding of plastic shell paintingproducts requires a certain period of time.The holding time is to prevent the melt back flow and cooling shrinkage.The cooling time ensures that the product is solidified and prevents deformation;the melting time is to ensure that the glue is fully melted;the drying time is to ensure that the product does not become elongated or defective.

The E-make company has 30 years of experience in custom-made production of injection molding.The plastic injection molding products will be exquisite in appearance,reliable in quality and delivered on time.If you want to customize the high-precision injection molding products.All information from customers was kept secret,we can sign NDA with you before starting any work.If you need any help,please feel free to contact us.

The Process Of CNC Machining

The Process Of CNC Machining

1. Confirm the machining area and the specification of machined parts.

a) Firstly,determine what process has been used to process this workpiece before and what process will be used to process it, and then confirm the relationship between these processes.

b) The condition of the workpiece before.For example,it was a casting parts or a forgeable piece or a bar parts,and the shape,the dimension,the machining allowance of workpiece and so on.

c) What area and shape need to be machined in next process.

2. Confirm the clamping way of the workpiece and design the fixture.

Select and design the fixture according to machining area,locating basis and clamping requirement of the workpiece.Mostly CNC machine will use three-jaw self-centering chuck to clapm the workpiece.

3.Confirm the machining method.

a)Determining the process principle,generally there are first rough then essence, near then far,inside then outside,the least procedure section, the shortest tooling route and special cases for special treatment.

b)In order to improve the production efficiency and ensure the finish machining quality of parts, the rough machining process shall be arranged first during cutting, and a large amount of machining allowance before finish machining shall be removed in a short time, and the allowance uniformity requirements of finish machining shall be met as far as possible.When the roughing process is finished, the semi-finishing and finishing should be arranged after the tool change.The purpose of arranging semi-finishing is when the uniformity of the remaining allowance after rough processing can not meet the finishing requirements,it can arrange semi-finishing as a transitional process,so that the finishing allowance is small and uniform.

c)Near than far is according to the distance from the machining position to the tool.Generally,to shorten the tooling distance and reduce the idle time,we will machining the position that more closed with the tool when are rough machining.Near than far is good for turning processing,whhich are the cutting conditions can be improved and keeping the rigidity of the blank or semi-finished parts.

d)For the parts need to be machined both of the inside surface and the outside surface ,we should machining the inside before outside when we are planning because it is difficult to control the size and shape of the inner surface, the tool rigidity is correspondingly poor, the durability of the tip edge is reduced by the heat of cutting,and chip removal is difficult during machining.

The above principles are not set in stone,some special cases may require a flexible approach.For example,some workpiece must be finished after rough processing to ensure its processing accuracy and quality.

Rapid prototyping manufacturing service

The inspection design prototype is not only visible but also touchable. Therefore, the prototype can vividly reflect the artistic creativity of the interior designer physically, preventing "drawing beautifully but making it unsightly “Shortcomings. So CNC prototyping services is indispensable in the development of new products and the deliberation of product appearance.

Check the structural design. Since the prototype is installable, the prototype can visually reflect the effectiveness of the product structure and the level of difficulty of installation, which is conducive to finding problems and solving difficulties in time. Prevent the risk of opening the mold immediately, because the cost of mold processing is generally very high. If the structure is found to be unscientific or other problems in the process of mold opening, the damage is obvious. Prototype manufacturing can prevent such damage and reduce the risk of mold release. Make the product launch time much earlier, because of the advancement of prototype production, you can use the prototype for product promotion before the mold is developed, and even the early sales and production preparations to occupy the market as soon as possible.

According to the manufacturing process, the prototype is divided into CNC prototype and manual prototype; CNC prototypes are mainly produced and processed by CNC machines. According to different production equipment, they are divided into laser rapid CNC prototypes and CNC prototypes.

During this period, the prototypes of laser rapid prototyping technology are mainly matched with SLA prototypes, that is, prototypes produced and processed by using the skills of laser rapid prototyping technology. It matches with other CNC prototypes: CNC prototypes. That is, the CNC machine is used to produce the processed prototype model.

Advantages of CNC prototype: The advantage of the CNC prototype is that it can accurately reflect the information content represented by the engineering drawings. The surface quality of the CNC prototype is very high, especially in the middle and later stages of production and processing. The parts need to be painted. Therefore, CNC manufacturing has increasingly become the mainstream of the prototype manufacturing industry.

If you want the prototype model to be close to the finished product and to detect the actual effect of the appearance, you must make a prototype model. After the prototype model is completed, it must be polished. What is the polishing of the prototype model?

Prototype model polishing is to eliminate burrs, oily dust on the surface of the part or the surface of the material, reduce the surface roughness of the surface of the product, and improve the adhesion of the coating after polishing the old paint film. Prototype model polishing can be divided into traditional manual polishing and modern polishing.

After a prototype part is CNC processed, its surface will inevitably cause many burrs and knife marks. At this time, it is necessary to manually solve this problem. Generally, people will choose sandpaper for sanding, or sanding and polishing. The basic appearance solutions include sanding, sandblasting, sanding and polishing, coloring, silkscreen ink, and electroplating.

As a professional manufacturer, we have the capabilities to produce the finest Visual Design Models, Full-functional Engineering Prototypes or Low volume production runs that allow you to proof your designs thoroughly, and help you to focus on key elements of product development.

Making Acrylic Prototype by 3D Printing, Vacuum Casting or CNC Machining

For small batch production, if we need to make the plastic product with acrylic material, generally we will prefer to make them by 3D printing process, vacuum casting serviceor CNC machining process. We can make the acrylic product by all this three process, but there much difference between them, whatever the machining way or the finished product.

The difference of the machining way.

If made by 3d printing, we will obtain an acrylic product but not transparent after printing, and then polish and painting UV coating to make them transparent. If made by vacuum casting, firstly we need to make a master mold of the product by CNC machining or 3D printing, and then we will polish the master mold to make them have a smooth surface, after that we will use the master mold to make a silicone mould, so that we can have a mold for casting. Finally we will remove the burr of acrylic parts and polish it to be total transparent. If made by CNC machining, we will need to program firstly, and then milling or turning the acrylic parts by CNC machine, after that, we will need to polish the product to make it total clear.

The difference of the material.

If made by CNC machining, we can use pure acrylic sheet material or bar material, so the strength of the product that make by CNC precision machining will be better. If made by vacuum casting, the material we can use is similar acrylic, not pure acrylic, so the product that make by vacuum casting is not strong as the product that make by CNC machining.

The difference of the processing time.

It will takes more processing time if make the product by CNC machining because we need to make the product one by one on the CNC machine. It will be more fast if make by vacuum casting because we can casting 8-10 pieces high quality product by using one mold.

It will be very fast if make by SLA 3D printing.

The difference of the product precision.

The product can have very high precision if made by CNC milling service, so if the customer require high precision for the product, NC machining process is a better option. The precision of the product that make by vacuum casting is not so high as CNC machining, and the precision of the product that make by 3D printing is more low.

The difference of the price.

Generally, the cost of the product that make by CNC machining is more expensive, but the final cost depends on the product specification that customer require.

Prototype injection molding

Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding methods and die-casting methods. Injection molding machine (abbreviated as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make various shapes of plastic products from thermoplastics or thermosets. Injection molding is achieved through injection molding machines and molds. Plastic injection molding is a method of plastic products. The molten plastic is injected into the plastic product mold by pressure, and then cooled and molded to obtain various plastic parts. There are mechanical injection molding machines dedicated to injection molding. The most commonly used plastics are polyethylene, ABS, PA, PC, polystyrene, etc.

As we all know, PC is commonly known as polycarbonate and has very good mechanical properties, so it is commonly known as bulletproof glue. And PC material has the characteristics of high mechanical strength, wide use temperature range, good electrical insulation performance, good dimensional stability, and transparency. Therefore, the use of PC materials can be used on many occasions. For example, it is widely used in electrical products, electrical instrument housings, and electronic product structural parts. On the other hand, there are many modified PC products, usually adding glass fiber, mineral fillers, chemical flame retardants, and other plastics. Another point is that PC materials have poor fluidity and higher processing temperatures, so the processing of modified materials requires a special plasticized injection structure. This is one of the characteristics of the PC. And Regardless of its mechanical properties or temperature range is very superior.PC also has the characteristics of good insulation and dimensional stability. It can be used in many situations Of course, the fire performance of PC is also good. But whether the design of the injection mold is reasonable will directly affect the quality of plastic products. The main factors affecting plastic shrinkage include thermal shrinkage, phase change shrinkage, orientation shrinkage, compression shrinkage, and elastic recovery.

These influencing factors are related to the molding conditions or operating conditions of precision injection molded products. Therefore, mold designers must have rich design and injection molding experience and must consider the relationship between these influencing factors and injection conditions and their apparent factors, such as injection pressure and cavity pressure and filling speed, injection melt temperature and mold temperature, Mold structure, and gate form and distribution, as well as the influence of factors such as gate cross-sectional area, product wall thickness, reinforcing filler content in plastic materials and orientation of plastic materials.

The E-make company has 30 years of experience in custom-made production of injection molding. The Prototype injection molding products will be exquisite in appearance, reliable in quality, and delivered on time. If you want to customize the high-precision injection molding products. All information from customers was kept secret, we can sign NDA with you before starting any work. If you need any help, please feel free to contact us.

What is the process of prototype?

In the design process of R&D products, after they have completed the design drawings, one of the things they want to do most is to know what the products they design are like in reality, and whether the appearance of the products is consistent with their own design ideas. , Is the structure design of the product reasonable, etc.? Prototype manufacturing is produced in response to this demand.

Classification of prototypes:

Prototypes can be divided into manual and numerical control prototypes according to the production methods:

Manual prototype: The main workload is done by hand.

CNC prototype: The main workload is completed by CNC machine parts, and depending on the equipment used, it can be divided into laser rapid prototyping (RP, Rapid Prototyping) prototypes and machining center (CNC) prototypes

A: RP prototype: mainly produced by laser rapid prototyping technology.

B: CNC prototype: mainly produced by machining center.

RP prototypes have their own advantages compared with CNC prototypes: the advantages of RP prototypes are mainly in their rapidity, but it is mainly formed by stacking technology, so RP prototypes are generally relatively rough, and there are certain requirements for the wall thickness of the product, for example, if the wall thickness is too thin, it cannot be produced.

The advantage of the CNC prototype is that it can accurately reflect the information expressed in the drawings, and the surface quality of the CNC prototype is high, especially after the surface spraying and silk printing are completed, it is even more glamorous than the product produced after the mold is opened. Therefore, custom prototype CNC machining has increasingly become the mainstream of prototype manufacturing.

According to the materials used in production, prototypes can be divided into plastic and metal prototypes:

(1) Plastic prototypes: The raw materials are plastic, mainly for prototypes of plastic products, such as televisions, monitors, telephones, and so on.

(2) Metal prototypes: The raw materials are aluminum-magnesium alloys and other metal materials, mainly for high-end products, such as notebook computers, high-end single players, MP3 players, CD players, and so on.

The necessity of prototype production

(1)Design inspection

The prototype is not only visible but also touchable. It can directly reflect the designer’s creativity in the form of physical objects, avoiding the disadvantage of “drawing to look good but not to make it look good”. Therefore, prototype production is indispensable in the process of new product development and product shape scrutiny.

(2)Check the structural design

Because the prototype is assemble able, it can intuitively reflect the reasonableness of the structure and the ease of installation. It is convenient to find and solve problems early.

(3)Avoid the risk of directly making molds

Because the cost of mold manufacturing is generally very high, relatively large molds are worth hundreds of thousands or even millions. If an unreasonable structure or other problems are found in the process of opening the mold, the loss can be imagined. Prototype production can avoid this loss and reduce the risk of mold opening.

The surface of the prototype: Electroplate, Anodized, Painting, polish, lase, etc.

If you have a new product that needs to make a prototype to design inspection and check the structural design. Please do not hesitate to contact us. As a prototype factory for 20 years. We can make any product.

The Difference between Industrial Design, Product Design and Mechanical Design

The Difference between Industrial Design, Product Design, and Mechanical Design Industrial design, product design, and mechanical design are both related but also different, some details as below.

An Industrial design is essentially an appearance design. The design and expression of the shape, the positional relationship between features, materials, colors, and surface treatment methods of industrial products, mainly the expression of beauty, are widely used in industrial supplies and handicrafts, Daily necessities, and other industries. In addition to the creative skills in aesthetics, industrial designers also need to be familiar with the working principle, function realization method, internal structure, product realization process, manufacturing method, mold realization method of the designed product. So that the designed product is achievable. By-products design generally refers to the internal structure design of products, the design of support, connection and position relationship between parts, as well as the realization of the function of the whole machine. It is generally applied to the structural design of non-transmission parts. There are also special cases. A small part of the product design also includes the appearance design, and then it will be done in the end together with the structural design. Product design also needs to master a very comprehensive knowledge, otherwise, the product is difficult to realize, or there will be defects such as high cost. Mechanical design is generally used in non-standard automation equipment, mechanical equipment, robots, and other industries, mainly focusing on products with many moving parts, and the whole machine is complex, expensive, has relatively high technical content, and so on. Mechanical designers need to have a solid knowledge of mechanical principles, mechanical analysis, and motion simulation, and also need to understand the relevant knowledge of each component. However, no matter what product design is better to make prototypes to verify and improve the product design before launching and mass production. The way we can use for making prototypes are 3D printing, NC milling, CNC spare parts, NC turning, CNC machined parts, vacuum casting, sheet metal, rapid tooling, etc. Which process is more suitable is up to the material and usage that the product requires.
