The Critical Parts That Make Your Dies Perform

A high-speed stamping press puts immense stress on tooling components. Punches wear down, and matrices chip. To prevent costly downtime, you need replacement parts that fit perfectly the first time.

JUMAI Tech leverages its extensive die-making expertise to manufacture independent mold components. Whether you need standard MISUMI/PUNCH equivalents or highly complex, non-standard custom shapes, our grinding and EDM departments deliver components with absolute dimensional stability.

Plug & Play Replacement

Manufactured to exact CAD tolerances, eliminating the need for bench fitting.

Custom Non-Standard Parts

We specialize in machining unique shapes based on your specific 2D/3D drawings.

Precision Components We Produce

Stamping Punches and Dies

Punches & Die Matrices

Formed, pierced, and custom-shaped punches and die blocks. Available in various tip geometries for blanking, coining, and deep drawing applications.

Guide Pillars and Bushings

Guide Elements

High-precision guide pillars and ball-bearing bushings. Ensuring perfect alignment between the upper and lower die shoes during high-speed stamping.

Tungsten Carbide Inserts

Carbide Inserts & Cores

Ultra-hard tungsten carbide components for high-wear areas. Drastically extends tool life in abrasive or extremely high-volume mass production.

Advanced Metallurgy

Materials & Surface Coatings

Selecting the correct steel and surface treatment is vital for preventing galling, reducing friction, and extending the MTBF (Mean Time Between Failures) of your mold.

High-Performance Tool Steels

We stock and machine premium materials including SKD11, SKH51 (HSS), ASP23 (Powder Metallurgy HSS), DC53, and Tungsten Carbide. We apply vacuum heat treatment and cryogenic treatments to optimize internal hardness.

PVD / CVD Surface Coatings

To combat adhesive wear, we offer advanced vapor deposition coatings. Options include TiN (Titanium Nitride - Gold) for general purpose, TiCN (Titanium Carbonitride - Grey) for harder materials, and DLC (Diamond-Like Carbon) for ultra-low friction.
