It is suggested in this paper that phenolic resin with three components and hybrid fiber were used to prepare clutch friction materials by cold-press process.

After using the cold extruding technology, abained good effect.

the advantages of the titanium alloy hexagon locking-nuts with flange with cold extruding technology replacing hot extruding working method are introduced.

The advantages of the reel internal gear with cold extruding technology replacing traditional metal cutting working method were narrated, and the technological for the reel internal gear was analyzed.

Optimizing aluminum alloy cold extrusion process;

This paper briefly introduces the features of the cool punch process and the main mechanical properties and processing performances of the commonly used light alloy materials,which provide the basis for selecting the suitable materials to satisfy the light weight requirement of the parts.

Cold extrusion processing is complexity,and affected by many factors,which cause design difficulty.

The initial design of cold extrusion process and die was obtained by code retrieval.
