Why Is It Easy to Produce Gas or Jet Marks at the Gate of Injection Molding Products?

The reason why the gate of injection molding products is easy to produce gas marks or jet marks may be caused by the following aspects:

1. Uneven plastic flow: The gate is the first place where plastic is injected into the mold, when the plastic flows into the mold, the flow speed, pressure and temperature will change, if these factors are not uniform, it will lead to uneven plastic flow at the gate, forming pores or jet marks.

2. Unreasonable mold design: Mold design is also one of the factors affecting the gas or jet pattern at the gate. If the design of the mold is not reasonable, such as the improper location of the gate, or the mold cavity design is not reasonable, it will cause the plastic flow at the gate to be uneven, resulting in gas or jet marks.

3. Plastic material is not suitable: Different plastic materials have different mobility and shrinkage rates, if the selected plastic material has poor mobility or high shrinkage rate, it is easy to produce gas or jet marks at the gate.

4. Improper processing process: Injection molding is a complex process, if the operation is improper, such as the injection temperature, pressure and speed are set improperly, or the injection cycle is too long, it is easy to lead to uneven plastic flow at the gate, resulting in gas or jet marks.

In view of the above reasons, the problem of gas or jet marks at the gate can be avoided or solved from the following aspects:

1. Adjust injection molding parameters: By adjusting injection molding parameters, such as injection molding temperature, pressure and speed, you can make the plastic flow more uniform and reduce the possibility of gas or jet marks at the gate.

2. Increase the number of gates: In the mold design process, the number of gates can be increased so that the plastic can flow more evenly into the mold, reducing the pressure and temperature difference at the gate, thereby reducing the generation of gas or jet marks.

3. Strengthen mold cooling: In the injection molding process, the temperature of the mold has a great impact on the flow and contraction of the plastic, so strengthening the cooling of the mold can make the plastic flow more uniform, reduce the pressure and temperature difference at the gate, thereby reducing the production of gas or jet marks.

4. Increase the wall thickness of the injection molded parts: Increasing the wall thickness of the injection molded parts can make the plastic subjected to greater resistance during the flow process, thereby reducing the pressure and temperature difference at the gate and reducing the generation of gas or jet marks.

What Are the Reasons Why Injection Molding Products Are Easy to Produce Bubbles?

1. The problem of plastic raw materials. If the plastic raw materials used contain water or other volatile substances, during the injection molding process, these water or volatile substances will be heated by high temperature and high pressure, evaporate into gas, and form bubbles.

2. Injection molding machine problems. If the operation parameters of the injection molding machine are set improperly, such as the injection temperature is too high or the injection speed is too fast, it will lead to the generation of bubbles. In addition, if the pressure of the injection molding machine is unstable or insufficient, it will also cause the air to be unable to discharge the mold and form bubbles.

3. Mold problems. If there are burrs, grooves and other defects on the inner surface of the mold, or the mold opening is not tightly sealed, bubbles will be generated during the injection molding process.

4. Problems with the injection molding process. During the injection process, the injection speed is unstable or the injection cycle is too short, which will make it difficult for the gas to be discharged from the mold and form bubbles. In addition, if the material is discharged immediately after injection molding, it is also easy to produce bubbles.

5. Properties of plastics. Different kinds of plastics have different physical and chemical properties, and some plastics are easier to produce bubbles during injection molding.

6. Environmental factors. Environmental factors such as temperature and humidity at the injection molding site will also affect the generation of bubbles.

7. Operator problems. When the operator is operating, there may be improper operation, such as opening the door of the injection molding machine during the injection molding process or rapid discharge, which can easily lead to the generation of bubbles.

In order to avoid the formation of bubbles, the following measures can be taken:

1. Optimize the ratio of raw materials and choose plastic raw materials with stable quality as far as possible.

2. Adjust the operation parameters of the injection molding machine, including injection temperature, injection speed, pressure, etc., so that it meets the requirements of injection molding products.

3. Optimize the mold design to ensure that the inside surface of the mold is smooth, without burrs and grooves, and the mold opening is tightly sealed.

4. Strictly control the injection molding process, and control the injection speed and injection cycle during injection molding to ensure that the gas can be smoothly discharged.

5. Carry out proper maintenance and maintenance to keep the injection molding machine and mold in good condition.

6. Strengthen the training of operators to ensure that they understand the principles and operation skills of injection molding processing, and can correctly operate the injection molding machine and mold to avoid bubbles.

7. By changing the injection molding environment, such as adjusting temperature, humidity and other factors, to reduce the generation of bubbles.

8. Adopt the gas discharge strategy during the injection molding process, such as setting the air valve in the mold, so that the air can be smoothly discharged from the mold.

9. Use injection molding simulation software to simulate injection molding process, analyze and optimize injection molding parameters, and avoid bubbles.

To sum up, the causes of bubbles in injection molding products are more complex, and a variety of factors need to be considered comprehensively. For different reasons, different measures need to be taken to solve the problem to ensure the quality and stability of injection molding products.

What Are the Molding Process Conditions of Injection Molding Products?

Injection molding process conditions of injection molding products mainly include the following aspects:

1. Temperature conditions: Injection molding needs to heat plastic particles to a melting state, and generally the injection molding machine will set the heater of the heating cylinder, the cylinder and the mold to provide heating conditions. Different plastic materials require different heating temperatures, and usually need to be tested before production to determine the appropriate temperature conditions.

2. Pressure conditions: Injection molding needs to apply a certain pressure in the mold, so that the plastic can fully fill the cavity of the mold, and can maintain a certain pressure time to prevent the production of shrinkage holes, bubbles and other defects. The size of the pressure should be set reasonably according to the pressure range of the injection molding machine and the shape and size of the product.

3. Injection speed condition: Injection speed refers to the speed at which the plastic enters the mold. Generally speaking, too fast injection speed will lead to bubbles, flow marks, poor welding and other defects, while too slow injection speed will lead to rough surface of the product and shorten the injection cycle. Therefore, the size of the injection speed needs to be adjusted during the mold test.

4. Cooling time conditions: Cooling time refers to the plastic products formed in the mold need to be cooled in the mold for a certain time before they can be taken out to avoid deformation, shrinkage and other defects. The length of the cooling time needs to be set according to the size and thickness of the product and adjusted during the production process.

5. Injection molding material conditions: Injection molding needs to choose the right plastic material, and adjust the temperature, pressure, injection speed and other conditions according to the characteristics of the material. Different plastic materials have different melting points and fluidity, so different process parameters need to be adjusted.

6. Mold conditions: Mold is the key to injection molding, it needs to meet the requirements of the product, such as the shape of the product, size, surface quality and so on. At the same time, the material and production process of the mold also need to be considered to ensure its wear resistance, corrosion resistance and precision requirements.

In conclusion, the injection molding process conditions of injection molding products include temperature, pressure, injection speed, cooling time, injection materials and molds. In the production process, these conditions need to be scientifically adjusted and controlled to ensure product quality and production efficiency.

The Influence of Plastic Mold Quality on Injection Molding Production

The purpose of mold design and manufacturing is for the mass production of injection parts with high efficiency and high quality, to produce high-quality plastic parts, the first mold is good, a good set of plastic molds is not just a good look, want to do a set of high-quality, high level, high precision plastic molds, from the following aspects.

1. The smoothness of the injection mold surface

The polishing of the mold surface is very important, which is one of the most important links to determine the success or failure of mold manufacturing. The surface of the mold is not smooth enough, its surface is uneven, and the surface of the plastic parts injected will have skin lines and sand grains. Generally, the polishing surface into a mirror is good, in addition to the choice of mold steel, grinding personnel, time, technology will have an impact on the polishing mirror effect, requiring a professional mold polishing master, experience to be particularly rich in order to accurately grasp the polishing time, to ensure the effect of mold mirror polishing.

2. Accuracy of mold

How to deal with the surface of plastic injection molding mold appears gloss defect?

Plastic injection molding mold will appear a lot of difficulties, injection molding mold is composed of two parts of the moving mold and the fixed mold, the production of plastic products need to use the mold injection molding, is through the injection molding machine will plastic raw materials into the injection mold cavity, after cooling and curing to form the injection molding parts. In the mold manufacturing process, how to deal with the surface of plastic injection molding mold appears gloss defect?

The following is the causes and solutions of the surface gloss defect of plastic injection molding mold and. Hope to help you.

1. The mold finish is poor, the cavity surface has rust, etc., the mold exhaust is poor.

2. The mold gating system has defects, should increase the cold well, increase the flow channel, polishing main channel, diverter and gate.

3. The material temperature and mold temperature are low, if necessary, the local heating method can be used at the gate.

4. The processing pressure is too low, the speed is too slow, the injection time is insufficient, the back pressure is insufficient, resulting in poor compactness and the surface is dark.

5. The plastic should be fully plasticized, but to prevent the degradation of the material, the heat should be stable, the cooling should be sufficient, especially the thick wall.

6. Prevent cold material into the parts, if necessary, use self-locking spring or reduce the nozzle temperature.

How to deal with the plastic injection molding raw material is not filled?

Electric injection molding machine in the production of injection mold will encounter the situation of injection molding is not filled, there is a lack of glue at the bone position right Angle and fuse connection, here to share some experience.

Analysis of glue injection is not filled:

1. The trapped air in the bone position makes the injection molding machine fill up.

2. The filling of the injection molding machine caused by the glue welding line is not filled.

Reason analysis of glue injection is not filled:

When the injection molding machine is working, the mold gluing method is two-point gluing, and the injection speed is too fast, which is easy to cause the gas trapped at the right Angle of the bone position and cause the filling dissatisfaction; If the injection speed is too slow, it is easy to fill the fuse at the end of the flow.

The solution:

Multistage injection molding and position switching.

In the first stage, the medium speed filling channel was used to pass through the glue inlet and switch the position; then, the second stage was used to quickly fill the vicinity of the bone site and switch the position; the third stage was used to slowly fill the bone site to discharge the gas; finally, the speed filling was used to switch the pressure holding position and the pressure holding time was extended appropriately.

Control of Injection Molding Parts Processing Temperature

There are many kinds of plastic, many plastic materials melting time are different, because the plastic does not have a specific melting point, the so-called melting point is a melting state of the temperature segment, the structure and composition of the plastic molecular chain is different, so the impact on its fluidity is also different, then in the production of injection parts manufacturers in the injection parts processing temperature control is also very important.

1. Mold temperature

Some plastic materials due to high crystallization temperature, slow crystallization speed, need higher mold temperature, some due to control size and deformation, or the need for demoulding, to higher temperature or lower temperature, such as PC generally requires more than 60 degrees, and PPS in order to achieve a better appearance and improve fluidity, mold temperature sometimes needs more than 160 degrees, Therefore, the mold temperature has an inestimable effect on improving the appearance, deformation, size and mold of the product.

2. Injection pressure

Melt to overcome the resistance required to advance, directly affect the size of the product, weight and deformation, different plastic products need different injection pressure, for materials such as PA, PP, increase the pressure will make its fluidity significantly improved, injection pressure size determines the density of the product, that is, the appearance of luster. It has no fixed value, and the more difficult it is to fill the mold, the pressure of the injection part increases.

3. Barrel temperature

The melt temperature is very important, and the injection cylinder temperature used is only a guide. The melt temperature can be measured at the nozzle or by air injection. The temperature setting of the injection cylinder depends on the melt temperature, screw speed, back pressure, injection volume and injection part cycle. If you do not have experience working with a particular grade of plastic, start with the lowest setting.

For ease of control, the cylinders are divided into zones, but not all are set to the same temperature. If operating for a long time or at high temperatures, set the temperature in Zone 1 to a lower value, which will prevent premature melting and diverting of plastics. Ensure that the hydraulic oil, hopper sealer, mold and injection cylinder are at the correct temperature before the injection parts begin.

4. Melting temperature

Melt temperature plays a major role in the flow performance of the melt, because the plastic does not have a specific melting point, the so-called melting point is a melting state of the temperature segment, the structure and composition of the plastic molecular chain is different, so the impact on its fluidity is different, rigid molecular chains are affected by temperature more obvious, such as PC, PPS, etc., and flexible molecular chains such as: PA, PP, PE and other fluidity by changing the temperature is not obvious, so should be adjusted according to different materials to reasonable injection molding parts temperature.

The Working Principle of Plastic Injection Mold

Plastic injection mold is an important plastic processing tool, through which plastic raw materials are transformed into products of various shapes and specifications. The principle of injection mold can be summarized as the following steps:

1. Plasticizing and injection

First of all, plastic raw materials undergo a series of processing treatments, such as drying, screening, mixing, etc., to become plasticized materials suitable for injection molding. In the heating barrel of the injection machine, the plastic begins to melt and plasticize under the action of heat, forming a uniform molten state. Subsequently, the plasticized plastic is pushed into the nozzle of the injection machine through the pushing action of the plunger or screw. When the plastic in the nozzle accumulates to a certain amount, the driving force of the injection machine stops, and the nozzle of the injection machine injects plastic into the pouring system of the mold. At this point, the pouring system introduces the plastic into the mold cavity.

2. Mold filling

Under the pressure of the injection machine, the plastic flows in the mold cavity and fills the entire cavity. In this process, the plastic is subjected to pressure and temperature, and continues to plasticize and melt. At the same time, the cooling system of the mold begins to work, and the heat inside the mold is taken away by the cooling channel or the cooling medium, so that the plastic is quickly cooled and shaped in the cavity.

3. Mold opening and release

When the plastic is cooled and hardened in the mold cavity, the mold is opened and the molded plastic product is pushed out of the mold cavity or removed from the mold. This process is called opening and stripping. When the mold is opened, the parting surface of the mold is opened, and the product is pushed out or taken out of the mold. The mold is then closed and ready for the next round of injection molding.

4. Other auxiliary actions

In the process of injection molding, some other auxiliary actions are also involved, such as the exhaust of the mold, the adjustment of the ejector mechanism, and the control of the mold temperature. These actions are essential to ensure the quality of the product and the stability of the production.

In summary, the principle of plastic injection mold mainly involves plasticizing, injection, filling, cooling, mold opening and mold release steps. These steps are coordinated to complete the injection molding process of plastic products. With the continuous progress of science and technology, plastic injection molding technology is also developing, and new injection machines, molds and processes continue to emerge, providing more choices and possibilities for the production of plastic products.

3. Mold opening and stripping

When the plastic is cooled and hardened in the mold cavity, the mold is opened and the molded plastic product is pushed out of the mold cavity or removed from the mold. This process is called mold opening and stripping. When the mold is opened, the parting surface of the mold is opened, and the product is pushed out or taken out of the mold. Then, the mold is closed and ready for the next round of injection molding.

4. Other auxiliary actions

In the process of injection molding, some other auxiliary actions are also involved, such as the exhaust of the mold, the adjustment of the ejector mechanism, and the control of the mold temperature. These actions are essential to ensure the quality of the product and the stability of the production.

In conclusion, the principle of plastic injection mold mainly involves plasticizing and injection, mold filling, mold opening and mold stripping. These steps are coordinated to complete the injection molding process of plastic products. With the continuous progress of science and technology, plastic injection molding technology is also developing, and new injection machines, molds and processes continue to emerge, which provide more choices and possibilities for the production of plastic products.
