Product Overview

Maximize the structural fatigue life of your stamping and cold forging machinery with our high-precision YG15 Stepped Tungsten carbide die Insert. Engineered as a high-durability core liner for steel casing molds, this cemented carbide component is explicitly formulated to withstand intense radial expansion forces and continuous mechanical shock during high-volume fastener production and metal extrusion lines.

Manufactured via premium powder metallurgy sintering and precision-ground to strict micrometric tolerances, this stepped die core guarantees absolute concentricity and an ultra-smooth inner bore finish. It dramatically minimizes friction, prevents material galling, and maintains long-term dimensional stability for your finished metal parts.

Typical Industry Applications

This custom-sized YG15 stepped carbide die core is highly recommended for:

• Fastener & Hardware Manufacturing: Cold heading die inserts for producing high-tensile bolts, rivets, nuts, and screws.

• Metal Cold Forming: Liners for forward/backward cold extrusion, cold drawing tubes, and severe-duty stamping blocks.

• Industrial Wear Components: High-pressure progressive die bushings and heavy-duty slurry valve sealing sleeves.

OEM/ODM Custom Manufacturing Capabilities

As a direct factory supplier, we specialize in full bespoke processing according to your engineering blueprints:

• Complex Internal Profiles: Dies with hexagonal, square, splined, or unique multi-stepped internal geometric configurations.

• Tailored Grade Matching: We optimize carbide compositions based on your specific application—whether you need lower cobalt grades (e.g., YG8/YG11) for pure abrasive wear or higher grades (e.g., YG20) for progressive deep drawing.

Grade	Scope of application
YG8	It is suitable for rough machining of cast iron, non-ferrous metals and non-metallic materials, stretching of steel, non-ferrous metals and pipes, various drill bits for geological use, tools for machine manufacturing and parts that are easy to wear.
YG11	Suitable for all kinds of metal and non-metal powder molding and stamping.
YG15	It is suitable for stretching of steel bars and steel pipes under high compression ratio, tops, perforation and stamping tools working under large stress, and mold cores for powder metallurgy automatic press molds.
YG20	With high strength, it is suitable for making stamping dies such as progressive dies: such as stamping watch parts, battery shells, small nuts, etc.
