Positive Displacement and Precision Dispensing: Technologies for Fluid Dispensing

An ideal process involving the application of fluids such as adhesives, ink, solder paste, grease and other liquids is to have a pre‐determined volume of material dispensed with accuracy and consistency. Positive displacement technology enables fluid dispensers to effectively control the volume of materials being dispensed. Precision Dispensing is available for precision applications. Fluid dispensers with this technology consist of a rotor/stator assembly and a motor drive unit that control the speed and number of rotations for precision dispensing. Read on to know more about positive displacement technology and precision dispensing method.

Positive Displacement Technology in Fluid Dispensers

Positive Displacement technology is the only volume measurement technology that measures the volume of the fluid passing through the dispensing valve. A fluid dispenser contains a dispensing valve inside. Within this valve, a cavity of desired volume is filled with a fluid/liquid, and then this volume is dispensed through the nozzle. Positive displacement principle helps to accurately measure thicker fluids.

Fluid dispensers with positive displacement technology consist of a tube which is pinched by pistons at two ends to form a cylinder of the appropriate volume. The volume of the fluid to be dispensed is controlled by the sequence of opening and closing of the pistons.

Precision Dispensing Technology in Fluid Dispensers

Precision dispensers feature micro-shot dispensing valves that can handle a range of materials. Apart from motor/stator assembly and a motor drive unit, there is a separate controller that allows programming of the motor to control fluid dispensing speed. At the end of the dispenser nozzle, the motor can be reversed to prevent dripping. Once the material to be used in the production process has been characterized through the computer control panel, precision dispensing unit will then dispense off a desired volume, regardless of material viscosity and ambient temperature.

The solution to efficient fluid dispensing is positive displacement and precision dispensing. Manufacturing technology has evolved, and these two principles – positive displacement and precision dispensing – are the solutions for customers that want improved performance during production process.

3 Reasons to Consider Air-Free Fluid Dispenser for Your Manufacturing Unit

In the past, the cost of the system and repeatability of the fluid dispensing process were the two primary decision points for choosing a fluid dispensing system. However, in today’s fully automated manufacturing units, operators look for automated fluid dispensing systems that feature air-free, precise dispensing. If you are still using air-driven liquid dispensing system in your manufacturing unit, here are three reasons why air-free fluid dispensing is a much better option.

Long Term Cost Savings

The fluid dispensers that depend on air pressure usually have a low purchase price, but you will end up paying more in the long term as air-driven dispensers increase energy costs, maintenance costs and wastage. Air-driven fluid dispensers use compressed air, which is the most expensive use of energy. By cutting the use of compressed air, you can reduce carbon footprint of your manufacturing plant. Air-free liquid dispensing system will enable you reduce energy costs and other maintenance-related costs, thus helping you save long term costs.

Enhance Quality and Functionality

With air-driven fluid dispenser, your product quality decreases as the dispensing process is exposed to dirt and moisture that originate in the pipe between the air dispenser and air compressor. The air pressure that develops in the pipe also results in the development of heat and changes in viscosity and homogeneity. All these changes during the dispensing process decrease the quality of your product. While with air-free fluid dispensing system, you can eliminate all these risks and get high quality end product. Air-free fluid dispensing systems also have faster cycles, so increasing functionality of the entire process.

Go Sustainable

By upgrading to air-free fluid dispensing system, you reduce wastage, carbon footprint, and energy usage. In short, you will make your manufacturing plant sustainable as well reduce negative impact on the environment.

Innovation in the manufacturing industry continues to advance at increasing speeds. By investing in automated fluid dispenser with air-free dispensing feature, you can produce high quality products, eliminate extra maintenance costs and reduce negative environmental impact. Now you know the reasons, it’s time to invest in automated liquid dispenser that has air-free dispensing process.

Why UV Curing is a Significant Industrial Boon?

UV Curing system is a technology that uses ultraviolet high intensity light to produce a photochemical reaction to instantly cure or dry coatings, adhesives and other bonding applications.

In recent years this technology has gained impetus and has proven its worth as a mechanism with essential use in many industries. UV Curing is primarily used as a smart solution in manufacturing industries as a drying agent by the original equipment manufacturers. A highly regarded technology which has proven to be extremely helpful and beneficial for cost effective productions.

In this blog let’s discuss why UV Curing is considered a significant industrial boon:

This technology is considered helpful in production as it is used in several important industries like aerospace, electronics, automotive, metal finishing, packaging, optical, plastic, medical devices, etc. The technology runs on enormous curing speed causing significant effects on production in manufacturing industries. Because of lesser man power required on curing process, lesser labor costs are spent and this has led to a significant decrease in assembly work stations because of which production is accelerated at better speed. The technology has not only increased the production but is cost effective and user friendly as well. With UV Curing technology, the final products are of enhanced quality and are safely manufactured.

For a technology driven mechanism, the equipment used are less expensive and it is far more simple and less cumbersome than other methods for curing like heat curing. It causes lesser waste as the curing material used here is essentially a single component. It is considered safe on environment as it does not use harmful chemicals which can cause any potential damage to the operator's health. It is also beneficial to the manufacturers as it does not entail a heavy regulatory or disposal cost indirectly affecting the production cost. Apart from its user friendly design and cost effectiveness, what UV Curing technology offers is accuracy and consistency drawing from its high intensity, described very well through its lamp height and line speed. UV Curing has revolutionized curing process and is therefore, a major technical boon to the industrial production and manufacturing.

3 Tips for Using Adhesives in Assembly and Packaging Operations

Adhesives are any substance that bind two different items together and resist their separation. There are three main types of adhesives: water-based, solvent-based and hot-melt adhesives. From food industry to electronic manufacturers, any business that uses adhesive in their manufacturing process such as assembly and packaging operations need to be careful with adhesive dispensing and application process. The amount of adhesive to be applied to a surface, the speed of application, and the adhesive cure speed – all these factors affect the end product quality. Your adhesive dispensing system and UV curing equipment are the controlling factors in your assembly and packaging processes. Here are three tips that will help you increase productivity during adhesive application process in the assembly/packaging line.

1. Prepare the Surface:

When using adhesives to bind two or more substrates, it needs to be ensured that the surfaces are cleaned properly. Any form of contamination can prevent bonding or reduce the bond strength as adhesive will bond to the contaminant and not directly to the substrate.

2. Use Automated Dispensing:

Adhesive applications don’t have to be a time consuming and challenging task in your process anymore. Get automated dispensing system installed at your manufacturing unit. You can leverage the accuracy and consistent speed of automated fluid dispensers for adhesive application in the production line. The excellent repeatability, high speed and precision will increase efficiency of your assembly operations.

3. Use UV Curing System:

Whether it is in the electronic, medical or general industry, manufacturing operations require high performance, high speed application and fast curing process. Due to the changing and demanding manufacturing processes, industries are now using UV light curing adhesives because of their short curing time and strong bond strength. For faster curing process, you need UV curing systems that are designed to cure adhesives in as little as a second.

Adhesives suit almost any application and can be used for wood, plastics, metal, glass, and more. Its strong bonding strength combined with automated dispensing systems and UV curing equipment has enabled manufacturing units to enhance their production efficiency and reduce downtime.
