Guide Sleeves with Oil Grooves DME Standard Shoulder Type SKH51 Materials for Plastic Injection Mold
Description
The guide bush is a kind of mold parts, which is used together with the guide pins to guide and ensure the accuracy of the movement. In the inner cylindrical surface usually has oil grooves, the quantity depend on the length of the guide bush.
Because of the wear resistance of SKD11 and SKH51, they are chosen as the production materials of guide bushes usually.
Quick Details
Between the bush and the leader pins, its generally require little fit clearance, less than 0.05mm.

Materials
SKH51 is a high-speed steel, the Japanese JIS grade, equivalent to the German DIN 1.3343, the United States M2.
It belongs to tungsten-molybdenum tough high-speed steel. The steel has fine and uniform carbide particles, high toughness, excellent cutting performance and good thermoplasticity. It has good wear resistance, especially resistant to high temperature of 600 °C without softening. It is suitable for manufacturing various tools that are wear-resistant and impact-resistant, advanced die, screw die, tools that require toughness and shape, milling cutters, drill bits, etc.
Processing
As the guide bush and guide pins with the size of the high precision requirements, and the inner cylinder and the outer circumference should be coaxial, therefore when manufacture the guide bush, it need to grinding in the inner cylinder first, and then install the mandrel grinding cylindrical surface.
Packing and Shipping
The guide bush are packaged with plastic bags with rust preventing oil, customized package is welcome.
About the shipping, all the well-known express companies and ocean shipping can be selected, but in remote areas, we can only use EMS.
