Product Description

Graphite mould performance:
1. Excellent thermal conductivity and conductivity.
2. Low linear expansion coefficient, good thermal stability and thermal shock resistance.
3. Chemical resistance is not easy to react with most metals.
4.in high temperature in most of the copper base tire body sintering temperature above 800 ºC) intensity increases with temperature rise
5. Good lubrication and abrasion resistance.
6. Easy to process, good mechanical processing performance, can be made into a complex shape, high precision mold.

Why  guide bush choose bronze with graphite column
Because of mold guide bush needs self lubrication, reducing The Times for refueling or don't come on, with high strength copper alloy (CuZn25Al5 CuZn24Al6Fe3Mn4) as basic material, according to a certain proportion according to the operating conditions in the working face processing out of the cavity and fill in the solid lubricant, high strength copper alloy provides high bearing capacity and the solid lubricant can be formed with low friction pair. Under the condition of dry friction, we design a pre-lubrication film on the bearing surface to ensure that the solid lubricant is transferred to the dual parts in the shortest time and to form an effective solid lubricant film.
