Precision Custom Cut Punch

Cut Punch,Trim and die punch maker

We will select the most suitable tungsten carbide or steel to fabricate the cut punch, the performance of the carbide plays a critical role in the semiconductor packaging industry, which needs high requirements for tolerance and stable performance. We are equipped with advanced machining devices to produce the bar cut punches, such as optical grinding from Waida and Wasino, and the sinker E.D.M from Sodick. All slots are grind by profile grinding with smooth surface finish and tolerance, which can improve tooling life by 50-100% for trim mold. We use the qualified tungsten carbide from well-known brands, such as FUJILLOY, Kennametal, EVERLOY, CERATIZIT, etc. They have higher resistance for certain precision metal stamping operations and reduce the maintenance time of metal stamping mold.

Tiebar Cut Punch

Tiebar Cut Punch

There is a small clearance between the slot teeth. The Wire EDM process can’t achieve the surface requirement. The profile grinding wheel can grind the slots with a width of 0.2mm and a depth of 5-6 mm.

Round Punch

Round Punch

Our precision manufacturing machines in our workshop can meet the demands of complex shapes. Such as Sinker E.D.M machining the harden material Asp23 with HRC62-64, the tolerance can reach +/-0.002mm.

Carbide Cut Punch

Carbide Cut Punch

There’s high precision in the semiconductor industry, we produce various cut punches with advanced equipment, such as optical profile grinders, and wire E.D.M to meet the top requirements in each process.

The Application in the Semiconductor Industry

Semiconductor-cut steel molds include cooperation with the upper cutting tool and the lower cutting tool. The upper cutting tools include its ontology and punch as a body of the blade, the lower cutting tool has placed the semiconductor product ontology pits and the carbide dies working as blade tooth. There is some clearance between the punch and die tooth blade set corresponding to the blade slot between the blade than stated on the cutter body thin, between the end face and horizontal bevel edge. When cutting the blade of the carbide bar cut punch is tilted and gradually cut, which can reduce burr, pin damage, and residual waste ribs while ensuring the cutting effect. And one-sided contact can be reached with the cutting bar at a certain angle, to make sure the tool wear is little, so that the service life of the semiconductor cutting bar mold can extend greatly
