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.

Precision Die Cut Punch Product show

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.

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

We are very sorry that all reamers are custom-made according to the customer’s requirements. So we don’t have any in stock.

The delivery time depends on the complexity of punching tools components and the purchasing quantity. we usually take about 7-15 days to finish them.

Dear customers, We will 100% inspect all dimensions of ordering ceramic parts before shipment, and generate detailed inspection reports. We will deliver to you together.

We placed great emphasis on the safety, timeliness, and efficiency of transportation. So we only cooperate with the best international logistics companies, such as DHL, UPS, and FedEx. We can accept EXW, FOB, DAP, DDP, and other service terms.

We are a direct tooling manufacturer, and T/T transfer is available. For the sample with a small amount, we can also accept credit cards, papal, western union, etc.
