Tungsten Carbide Punches and Punch Pins

Precision carbide punches and punch pins for stamping, piercing, forming, and high-cycle tooling.

Product Overview

Tungsten Carbide Punches and Punch Pins are precision tooling components designed for demanding metal forming, stamping, piercing, and cold forming operations. Made from cemented tungsten carbide, these punches provide excellent wear resistance, high compressive strength, dimensional stability, and long service life under repeated production cycles.

Compared with conventional tool steel punches, carbide punches can maintain cutting edges and working dimensions for longer periods, helping reduce tool changes, downtime, and inconsistency in high-volume production. They are particularly suitable for applications involving hard materials, thin metal sheets, stainless steel, copper alloys, electronic components, fasteners, and precision formed parts.

KENIN Carbide manufactures carbide punches and punch pins according to customer drawings, samples, or operating requirements. Available designs include round punches, square punches, shaped punches, stepped punches, heading punches, piercing punches, ejector pins, and other custom precision tooling components.

Applications

Tungsten carbide punches and punch pins are widely used in precision metalworking and high-cycle production tooling where long service life and dimensional consistency are required.

Typical applications include:

– Metal stamping and sheet metal punching
– Precision piercing and blanking operations
– Cold heading and fastener manufacturing
– Connector, terminal, and electronic component production
– Powder compaction and forming tooling
– Automotive parts and precision hardware manufacturing
– Stainless steel, copper alloy, and hard material processing
– Progressive dies and high-speed stamping dies

Custom Manufacturing

KENIN Carbide supplies custom tungsten carbide punches and punch pins based on customer drawings, samples, or technical requirements. We can manufacture standard and non-standard punch designs for different stamping, piercing, forming, and cold heading applications.

Custom options include:

– Carbide grade selection based on wear resistance, toughness, and impact conditions
– Round, square, rectangular, stepped, tapered, and special-shaped punch profiles
– Custom diameter, length, head design, working length, and shank geometry
– Precision grinding for critical tolerances and concentricity requirements
– Surface finish options including ground, polished, lapped, or customized finishes
– Working-edge geometry for piercing, blanking, forming, or heading operations
– Custom inspection requirements, marking, packaging, and batch traceability
