What is the testing process for Auto Parts Micro Screws processing?

2025,09,18

Hardness testing for Auto Parts Micro Screws processing uses a Rockwell hardness tester. Small auto parts Micro Screws have complex shapes, and the surfaces they can be tested on are very small, making them difficult to test on a standard benchtop Rockwell hardness tester.

Stamping processes include stamping, bending, drawing, forming, and finishing. Materials used in Auto Parts Micro Screws processing are primarily hot-rolled or cold-rolled (predominantly cold-rolled) sheet metal.

Such materials include carbon steel, alloy steel, spring steel, galvanized sheet, tinplate, stainless steel, copper and copper alloy sheet, and aluminum and aluminum alloy sheet.

The PHP series portable superficial Rockwell hardness tester is ideal for testing the hardness of these Auto Parts Micro Screws. Alloy Auto Parts Micro Screws are the most commonly used parts in metal processing and machinery manufacturing.

Stamping is a process that uses dies to separate or form metal strips. It has a wide range of applications.

The main purpose of Auto Parts Micro Screws hardness testing is to determine whether the annealing level of the purchased metal sheet is suitable for subsequent Auto Parts Micro Screws processing.

Different types of Auto Parts Micro Screws processing require different hardness levels for the steel sheet. Aluminum alloy sheet for Auto Parts Micro Screws can be tested using a Webster hardness tester.

When the material thickness is greater than 13mm, a Barcol hardness tester can be used. Pure aluminum plates or low-hardness aluminum alloy plates should use a Barcol hardness tester.
