Mold Development Technology

Our mold development for powder metallurgy integrates precision design, material optimization and process simulation. We first customize 3D mold models via CAD software, tailoring cavity structures to part geometries and powder flow characteristics. High-wear-resistant materials like H13 steel are selected for mold cores, undergoing quenching and tempering to reach 50-55 HRC hardness. We also apply nitriding treatment to enhance surface durability, extending mold lifespan by 30%+. Before mass production, we conduct finite element analysis (FEA) to simulate powder compaction, adjusting parameters to avoid defects like cracks. This iterative process ensures molds meet tight tolerances (±0.02mm) and stable production of high-density powder metallurgy components.

Mold Development Process

The die development process is a critical sequence from design to validation. It begins with product and die design, followed by precision machining, heat treatment, and assembly. The final stage involves tryouts and adjustments on production presses to ensure the tool meets all specifications for quality, functionality, and durability before mass production.

Product and Mold Design:This phase involves collaborative design of the product and its corresponding die. It focuses on optimizing part geometry for manufacturability (DFM) and defining the tool's cavity, core, and ejection system.
