Product introduction

Bi-alloy Zhoushan screw manufacturers use high-quality SACM645 alloy steel as the base material, and weld the imported bi-metal layer on the top of the thread.

Detailed introduction

The material of the double alloy Zhoushan screw manufacturer uses high-quality SACM645 alloy steel as the base material, and the imported bimetal layer is welded on the top of the thread; the bimetal barrel uses high-quality 38CrMoALA as the base material and is subjected to quenching treatment; Double alloy screw barrel: with wear resistance, corrosion resistance, high temperature resistance, high pressure resistance, suitable for lens, transparent shell, cosmetics container, transparent acrylic, nylon, PVC, PC, PPA, PPO, PPS, PA6T, LCP, ABS fireproof, bakelite, PC + glass fiber, nylon + glass fiber, magnetic powder, ceramic powder, aluminum-magnesium powder, iron powder, electric injection molding machine, etc., can also be designed and customized according to user processing product requirements.
Design principle of double alloy Zhoushan screw manufacturers:
The main part of the pin screw is an ordinary screw, and the pin can be set in the falling groove of the melting section or the metering section of the screw or a smooth cylindrical surface without a screw groove at the end of the metering section. The pins are arranged in a certain arrangement, which can vary in density and quantity. The cylindrical pin is formed by assembling the pin into the hole of the screw; the square or diamond pin is formed by milling the pin directly on the screw.
If these pins are set in the melting zone, the pins can break the solid bed, disrupt the two-phase flow, stir the solid and liquid phases together, and increase the contact area between the undissolved solid phase fragments and the contained material, and promote Melting. If the pin is set in the melt conveying area, its main function is to divide the material flow, increase the interface, change the direction of the material flow, and rearrange the flow beam. Diverted and merged many times to change the flow direction and make the melt composition and temperature uniform.
