Product introduction

The mixing screw manufacturer is a professional manufacturer of extruder XPS foam plate screw, precision sol barrel for injection molding machine, parallel screw, conical screw, building block screw, barrel and accessories.

Detailed introduction

The material for the production of mixing screw products is made of high-quality gold-containing steel (38CrmoALA), which is precisely manufactured through adjustable quality and qualitative, surface nitriding, polishing and other processes, and has the characteristics of precision wear resistance.
Reasons for wear of mixing screw :
1. Each plastic has an ideal plasticizing processing temperature range, and the barrel processing temperature should be controlled to bring it closer to this temperature range. When granular plastic enters the barrel from the hopper, it will first reach the feeding section. Dry friction will inevitably occur in the feeding section. When these plastics are insufficiently heated and unevenly melted, it is easy to cause increased wear on the inner wall of the barrel and the screw surface. Similarly, in the compression section and the homogenization section, if the molten state of the plastic is disordered and uneven, the wear will also increase.
2. Speed should be adjusted properly. Because some plastics are added with reinforcing agents, such as fiberglass, minerals or other fillers. The friction of these materials on metallic materials is often much greater than that of molten plastic. In the injection molding of these plastics, if it is made with a high speed, it will not only increase the shear force on the plastic, but also strengthen the production of more shredded fibers. The shredded fibers contain sharp ends, which will cause wear The force is greatly increased. When inorganic minerals glide on the metal surface at high speed, its scraping effect is not small. Therefore, the speed should not be adjusted too high.
We can not only process samples and manufacture, but also design, survey and manufacture according to the special requirements of customers, or use bimetal repair work on old screws. The service life of bimetal screws is longer than that of ordinary nitriding screws. 3-May we Products for you to squeeze gold and silver!
Single screw extruder screw types and uses: ordinary type, progressive type, sudden type, mixing type, separation type, pin type, exhaust type, barrier type, split type, wave type, acceleration type Silk, granulation, drawing, blown film, extruded header, foaming, extruded sheet, extruded board, etc.
Jinfeng's promise: "Customer's requirements, Jinfeng's mission" "Professional precision screw and barrel manufacturer" "Professional refurbishment of old barrels"!
After long and unremitting efforts of Jinfeng people, they have advanced process equipment and technical force. At present, it has a full set of production lines and perfect testing facilities to ensure the quality of the products, and the technical indicators have reached 100%, which meets the requirements of customers.
