Tungsten Carbide Punch for Tool and Die Components
Tungsten Carbide Punch for Tool and Die Components
Reliable tool and die component supplier providing tungsten carbide punches made by PG profile grinding. High precision, custom manufacturing based on customer drawings.
As an experienced tool and die component supplier, we manufacture high-precision tungsten carbide punches and Inserts using advanced PG profile grinding technology. These punches are designed for demanding stamping and forming applications where dimensional accuracy, edge quality, and long service life are critical.
Why Choose PG?
PG profile grinding allows us to produce complex punch geometries with excellent profile accuracy and superior surface finish. Compared with conventional machining methods, PG grinding ensures tighter tolerances, sharp cutting edges, and consistent repeatability, making it especially suitable for progressive dies and precision stamping tools.
Tungsten carbide is selected for its high hardness, outstanding wear resistance, and stability under high-load production conditions. This makes the punches ideal for high-volume stamping, fine blanking, and applications requiring extended tool life. Each punch is custom-manufactured strictly according to customer drawings, ensuring accurate fit and reliable performance within the die assembly.

As a professional tool and die component supplier, we support both prototype and small-to-medium batch production. Material options, tolerances, and surface finish can be optimized based on different application requirements, punching materials, and expected tool life. In addition to tungsten carbide, alternative tool steels can be provided upon request.

FAQs
We typically achieve ±0.002 mm tolerance with PG optical profile grinding.For simpler geometries or specific critical features, tolerance can reach to ±0.001mm. Final capability depends on part geometry, material, and profile complexity.
We typically grind radii as small as R0.02 mm (tool steel) and R0.01 mm (carbide).
All sharp corners are produced with a controlled micro-radius for durability and performance.
Yes. We specialize in complex and asymmetric PG-ground profiles, including compound curves and non-symmetrical shapes.

PG optical profile grinding provides significantly higher profile accuracy and repeatability than standard grinding, especially for parts with complex contours and functional edges.
Compared with standard grinding, PG grinding offers:
Superior profile accuracy for curves, angles, and asymmetric shapes
Direct optical profile verification during grinding
Cleaner, sharper cutting edges with controlled micro-radius
Better consistency across multiple identical parts
Standard grinding is well suited for straight surfaces and simple geometries.
However, when the function of a punch or insert depends on precise contour shape, PG optical profile grinding ensures the profile matches the design intent exactly.
For precision molds, connector tooling, and fine-pitch stamping applications, PG grinding often results in more stable performance and longer tool life.
