China Hot-DIP Galvanized Ground Anchor Screw
Descriptions:
The screw is in a shape of a cylinder with a spiral groove cut on the outer surface or a cone with a spiral groove cut on the conical surface.It has many types with different head shape,such as external hexagonal screw,large flat screw and socket hexagon screw and so on.
Material requirement:
As the screw is working in condition of high temperature,certain corrosion, strong wear and large torque,it must reach the following requirements:
1) high temperature resistance, no deformation at high temperature;
2) wear resistance, long service life;
3) corrosion resistance, corrosive materials;
4) high strength, can withstand large torque, high speed;
5) good cutting performance;
6) low residual stress and thermal deformation after heat treatment.
Application:
The screw is generally 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,which is the heated extrusion plasticized part and the core of plastic machinery.
Moreover,the screw is widely used in machining center,CNC machine,CNC lathe, injection molding machine, wire cutting, grinding machine, milling machine, slow wire, fast wire and PCB drilling machine, fine carving machine, carving and milling machine, spark discharge motor, tooth biting machine, planer, large vertical car gantry milling and so on.
