Tungsten Carbide
Tungsten carbide is formed and pressed ,the carbide is approximately twice as hard as steel ,and twice as density as steel.


Tool Steels
The tools steels have their distinctive hardness,resistance to abrasion.


Ceramics
The ceramic material has various hard ,brittle,heat-resistant.

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 .

Punch and Die Application

stamping

Cold forming die The cold forming is one of the metal stamping process that plastically deforms metal using dies ,Sundi manufactures carbide cold forming dies for the auto and electronic parts application

Deep drawing

The deep drawing is a metal forming process .If the parts have higher surface roughness requirement ,we usually choose the CVD coating to improve the tooling life

Semiconductor and Electronics

The carbide punches and dies are widely used in the stamping the lead frame in the semiconductor ,trim and form in the electric industry

The Advantage of Punch and Die

Wear Resistance:

Great were resistance is one of the most important functions during metal working . the were resistance depends on the friction. Yet the friction from  punch surface and workpiece will affect the working life .We design and manufacture the punches & dies with good finish . So they  will reduce the friction and  extend the tooling life

High Temperature Resistance:

When the working temperature is raising ,the poor die and punch will make the molds out of shape . Or we have to replace the punch and die frequently .So the material of the molds should have higher temperature stability . Good material will make sure the whole mold parts in good hardness and strength.

Good Flexibility:

The working condition puching tool is very strict, it need a loading resistance to avoid breaking. So the higher loading resistance flexibility is very important to make sure the mold working stability
