Customized Molds

The development of powder metallurgy molds is a crucial part of the powder metallurgy process, directly influencing the final product's shape accuracy, dimensional stability, and surface quality. Below are the general steps involved in the development of powder metallurgy molds.

01/ Design Planning

Initially, it is essential to formulate the design plan for the molds based on the specifications and requirements of the parts to be produced. This involves considerations such as the geometric shape of the molds, material selection, cooling systems, and the number of mold releases.

02/ Mold Material Selection

Based on the characteristics of the powder metallurgy process and the materials of the parts being produced, appropriate mold materials are chosen. Commonly used mold materials include high-speed steel, hard alloy, tungsten carbide steel, tool steel, etc.

03/ Mold Design

Following the design planning, the specific design of the molds is conducted. This includes the internal and external structural design of the molds, cooling system design, and considerations for mold lifespan.

04/ Manufacturing Processing

Utilizing machining, electrical discharge machining (EDM), wire cutting, grinding, and other processes, the design drawings of the molds are transformed into actual mold components.

05/ Assembly and Debugging

The machined mold components are assembled, and the molds undergo debugging and testing. This includes testing the opening and closing performance of the molds.

06/ Trial Production and Verification

Using the molds for trial production, the shape accuracy, dimensional stability, surface quality, and other indicators of the parts are inspected. Based on the inspection results, necessary adjustments and improvements are made.

07/ Mass Production

After successful trial production and verification of the molds, mass production can commence. The molds are used for large-scale production of parts.

Throughout the development process of powder metallurgy molds, close collaboration among process engineers, design engineers, mold manufacturers, and other personnel from various stages is crucial. This collaboration ensures that the design and manufacturing of the molds meet production requirements and can produce parts that meet quality standards.
