Zhoushan screw factory: we are the best choice!!!

First introduce the screw!!

It can be seen from the extrusion process that the screw is working in high temperature, corrosion, intense wear and high torque. Therefore, the screw must:

1) high temperature and non-deformation under high temperature;

2) wear and tear, long life;

3) corrosion resistant and corrosive materials;

4) high strength, high torque, high speed;

5) have good cutting performance;

6) small residual stress after heat treatment and small thermal deformation.

Common materials:

At present, the commonly used screw materials in China are 45 steel, 40Cr, ammonification steel, 38CrMOAl, high temperature alloy etc.

1) no.45 steel is cheap, good processing performance, but poor wear resistance and corrosion resistance.

Heat treatment: tempering hb220-270, high frequency quenching HRC45-48.

2) the performance of 40Cr is superior to that of no.45 steel, but it is often plated with a layer of chromium to improve its ability to resist corrosion and wear resistance. However, it has a high demand for chrome-plated layer. The coating is too thin and easy to wear. It is too thick and easy to flake off.

Heat treatment: hb220-270, hard chrome HRC > 55

3) the comprehensive properties of nitride steel and 38CrMoAl are excellent and widely used. The general nitrogen layer reaches 0. 4-0. 6 mm. But this material is low in resistance to hydrogen chloride and is high in price.

4) high temperature alloy material is superior to other materials, the material need not coating, it is mainly used for injection molding machine halogen-free, screw, high oxidation corrosion resistance of the material, heat treatment hra55 ` 60.

The use of the screw:

It is used in plastic molding equipment, such as plastic profile extruder, injection molding machine, etc. The screw and barrel are the core parts of plastic forming equipment. It is the part of heating extrusion. Is the core of plastic machinery.

Screw is widely used in machining center, CNC machine, CNC lathes, injection molding machine, wire cutting, grinding machine, milling machine, wire walking, brisk walking wire, PCB drilling machine, carved machine, engraving and milling machine, spark machine, bite the tooth machine, planer, large vertical lathe milling machine and so on.

We supply screw rod, conical twin screw, cylinder, parallel twin screw and so on. Welcome to purchase.
