Granule screw side feeder for plastic injection industry
1.High precision dosing control system based on loss-in-weight principle.(resolution: one per four millions)
The granule screw side feeder is a game-changer in the plastic injection industry. With its high precision dosing control system based on the loss-in-weight principle, it can achieve a resolution of one per four million. This level of precision is unmatched and ensures that the materials are dosed accurately, reducing waste and improving efficiency.
2. Self-adaption ratio control, automatic correction of feeding error, enhance the precision rating high up to 99.7%.
Additionally, the patent unique interior screw feeding mechanical design enhances the feeding accuracy, making it more stable and reliable. The self-adaption ratio control system also adds to the precision rating by automatically correcting feeding errors, which results in the high precision rating of 99.7%.
3. Two model series to work for granule & powder separately.
This side feeder comes in two model series that can work for granules and powders separately, making it versatile and adaptable to various industry needs. It's an excellent investment for any plastic injection manufacturer seeking to improve the accuracy and efficiency of their dosing systems.
4. Minimum feeding volume down to 50-100 g/h.
5. More reliable with branded hardware and full intellectual property rights software.

Side Feeder FAQ
1. What is the precision rating of the dosing control system based on the loss-in-weight principle?
The precision rating of the dosing control system based on the loss-in-weight principle is very high, with a resolution of one per four millions. This ensures that the correct amount of material is delivered each time, which is crucial for the quality of the injection-molded products.
2. What is unique about the interior screw feeding mechanical design of the granule screw side feeder?
The granule screw side feeder has a patent unique interior screw feeding mechanical design, which ensures smooth and consistent feeding of the granules. This design also helps to prevent clogging and other issues that can affect the quality of the final product.
3. How does the self-adaption ratio control work?
The self-adaption ratio control is an automatic correction system that helps to enhance the precision rating of the granule screw side feeder up to 99.7%. It works by detecting any feeding errors and adjusting the feeding ratio accordingly, ensuring that the correct amount of material is always delivered.
4. Can the granule screw side feeder work for both granule and powder materials?
Yes, there are two model series of the granule screw side feeder, one that is designed to work with granules and one that is designed to work with powder materials. This makes the feeder a versatile solution for the plastic injection industry, capable of handling a wide range of materials and applications.
