Smooth Mold Guide Bushings with Oil Grooves DME Standard Shoulder Type SKD11 Materials for Injection Mold
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.
Between the bush and the leader pins, its generally require little fit clearance, less than 0.05mm.

we have the following standard sizes of leader bushing in stock, generally can be shipped within 3 working days.
If customized, please let us know the following values or send us a drawing, the delivery time is generally 15-20 days.
SKD11 is a kind of high carbon high chromium alloy tool steel. It has high hardness and wear resistance after heat treatment. It has strong hardenability and good dimensional stability. It has good toughness and high temperature fatigue resistance and can withstand temperature fusion. So It is suitable for long-term work at high temperature with good cutting performance and polishing performance, suitable for high precision long life cold working die and thermosetting formed plastic mold.
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.
