Causes of cracking in Auto Parts Micro Screws

Cracks can occur if processing pressure is too high, speed is too fast, filler is excessive, injection and holding times are too long, and internal stress is excessive. Adjust the opening speed and pressure to prevent mold release cracking caused by excessively deep drawing of the part. Injection pressure is too low or injection speed is too fast. Prevent cracking caused by weld cracking and plastic degradation. Use mold release agents correctly and be careful to remove mist and other...

Advantages of nickel plating on Aerospace Micro Screws

Aerospace Micro Screws can be coated to improve their performance and make up for their shortcomings. The advantages of nickel plating on Aerospace Micro Screws are introduced below. The nickel plating layer of Aerospace Micro Screws has high stability in the air. Because nickel has a strong passivation ability, a very thin passivation film can be quickly formed on the surface, which can resist the corrosion of the atmosphere, alkali and some acids. Chemical nickel plating has extremely fine...

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

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...
