1. Fully Pneumatic Secondary Metering System

In terms of measurement, we have developed and designed a fully pneumatic secondary metering pump based on the measurement characteristics of the civil industry feeding system, breaking the traditional way of using hydraulic systems in China. It is generally believed that the pressure of the pneumatic system is lower than that of the hydraulic system, but this needs to be calculated according to different cylinder diameters. In fact, at a pressure of 0.5MPa, the output of our designed metering system is greater than that of other brands of hydraulic systems. This system has the advantages of no maintenance, cleanliness, and low energy consumption, and has been well received in the industry.

2. No glue leakage

Kawasaki has been working hard for many years to deal with glue leakage in the feeding pump body and pipeline. Now Kawasaki's feeding pump has gained customer recognition for its feature of no glue leakage.

Kawasaki promises to replace the entire pump body free of charge if customers discover glue leakage in Kawasaki's feeding pump.

3. High adhesive efficiency

Kawasaki's feeding pump has a glue dispensing efficiency about four times that of other domestic brands. This has significant advantages for high-speed injection molding. In practical applications, some customers even use one Kawasaki feeder to feed two injection molding machines.

4. A and B glue balance

We have designed a suitable proportional adjustment method for our feed pump structure. D521 further adopts an automatic adjustment method, and the proportion setting does not require manual participation. According to the instructions in our manual, it is easy to ensure the balance of A and B glue, that is, to ensure that both buckets can change glue at the same time.

This is a crucial element in reducing waste of rubber materials and ensuring product quality. The technology we have gained from the experience of developing high demand feeding systems in the power industry has been applied to the civilian industry and achieved significant results. This is also a major reason why many customers choose us.

For this issue, we can guarantee that if the A and B adhesives cannot be loaded and replaced simultaneously as promised, ensuring a balanced ratio of A and B during the feeding process, customers can choose to return the product.

5. Less waste

According to customer feedback, we always need to release a portion of the adhesive before emptying the pressure plate. This always results in waste of adhesive material, as the adhesive flowing onto the pressure plate is difficult to recycle and reuse.

Therefore, Kawasaki adopted another way of exhaust, without the need to discharge the glue, let alone onto the pressure plate. This greatly reduces the waste of adhesive material and makes the operation cleaner.

6. Improved shut-off valve

We have adopted a more reliable shut-off valve design, which can reliably cut off even with high injection pressure during screw injection, preventing inaccurate injection and feeding.

7. Improved pneumatic nozzle

Kawasaki's pneumatic nozzle has undergone significant improvements based on years of practical experience. Not only is it small in size, but it also has a compact structure, high reliability, and minimal maintenance.

In this design, the water transport part covers the entire nozzle section, with silicone, cooling water, and compressed air all integrated into a sophisticated structure. It has the advantages of good cooling effect, reliable sealing, and strong force.

Practical application has shown that this new pneumatic nozzle can greatly improve the injection precision of injection molding machines.

8. Characteristics of Kawasaki's color paste system

A complete colorant system consists of a colorant pump and a colorant metering valve.

The basic parameters of the color paste pump are as follows:

1. Maximum working pressure: 200bar

2. Gas source pressure: 0.4-0.8MPa

3. Addition ratio: 0.3-4% (combined with the main agents A and B)

All Kawasaki's feeding systems have pre installed control programs for the color paste, and the mechanical parts have interfaces for the color paste system, making it easy to install and remove the color paste system.

At the same time, we also considered the convenience of adjustment in the design of the measuring mechanism, which includes digital indicators. This way, when customers want to achieve the original color paste addition effect, they can remember the previous value and easily restore the original addition amount, greatly reducing the debugging work.
