Trim Tool and form dies

In the metal stamping tools. The punch and dies are widely used to press the material into different shapes or cut the material. Some of them are not precision because of the end-products needs ,but some are not ! Especially in the electronic and semiconductor industry ,the accuracy will reach +/-0.001mm .

Typically carbide or hard steel are used to make the punch and die. Compared with the steel ,the carbide material has higher hardness and strength , they greatly extend the service life of your tools. Our comprehensive range of products have wide application in various industries .

Therefore ,the state-of-the-art machining equipment and technology are very important . They’re applied to ensure the consistent quality,high precision,excellent working performance . Also the TICN and DLC coating are available to extend the tool life and improve the end-part quality .

The Working Requirements of Punch Tooling

Wear Resistance

The punch tooling is deformed in the die cavity when it flows and slides along the surface of the cavity . this situation will result in great friction between the surface of the cavity and the workpiece material,which leads to the failure of the punch tooling due to poor wear. So the wear resistance of punch tooling is one of the basic and important properties of the stamping tooling.

Strong toughness

Most of the mold working conditions are very bad, and some of them often bear large impact load to brittle fracture. In order to prevent the punch tooling components suddenly broken when working, the punch tooling material should  have a high strength and good toughness. The toughness of punch tooling mainly depends on the carbon content, grain size and microstructure of the material.

High Temperature Resistance

When the working temperature of punch tooling is higher, the hardness and strength will decrease, resulting in early abrasion and deformation until failure.Therefore, the punch material should have higher tempering stability  to ensure that the punch tooling has higher hardness and strength at working temperature.

Fatigue Fracture Resistance

In the cycle working process for  the long-term action, fatigue fracture often occurs .   Its forms include small energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture resistance of punch tooling mainly depends on its strength, toughness, hardness and inclusion content in the material.

Cold and Hot Fatigue Resistance

Some punch tooling are always in the state of repeated heating and cooling in the process of work, so that the cavity surface will be cracking and peeling under tension, pressure stress,while increasing friction, plastic deformation and reducing the dimensional accuracy,  punch tooling will failure. Cold and hot fatigue is one of the main failure forms of hot working die punch. This kind of punch tooling should have high cold and hot fatigue resistance.
