Stamping material and mold testing

1. Metal stamping parts; Hardness testing of materials

The hardness testing of stamping materials is mainly aimed at determining whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping processing. Different types of stamping processing techniques require sheets of different hardness levels. Aluminum alloy plates used for stamping parts processing can be tested using a Vickers hardness tester. When the material thickness is greater than 13mm, a Babbitt hardness tester can be used instead. Pure aluminum plates or low hardness aluminum alloy plates should use a Babbitt hardness tester.

2. Hardness testing of metal stamping parts molds

The main material for stamping dies is die steel (including tool steel and high-speed steel), and sometimes hard alloys are also used.

Stamping molds usually require high hardness and toughness, and heat treatment is necessary.

Small and complex shaped stamped parts can be used to test surfaces that are too small to be tested on ordinary desktop Rockwell hardness testers. The PHP series portable surface Rockwell hardness tester is suitable for testing the hardness of these stamped parts. Alloy stamping parts are commonly used components in metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal plates and strips. Its application range is broad. Stamping processing includes processes such as punching, bending, deep drawing, forming, and finishing. The materials used for stamping processing are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet and strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plated plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.
