What are the key design principles for Auto Parts Micro Screws?

Auto Parts Micro Screws are not common in everyday life, but they play a significant role in industrial machinery manufacturing. Larger parts, in particular, require auto parts Micro Screws for processing to achieve proper production efficiency and performance. Below, we will explain the design principles for Auto Parts Micro Screws.

1. Dimensional stability: During the molding process, the surface of the plastic part in contact with the Auto Parts Micro Screws should maintain greater dimensional stability than the surface away from the vehicle. In the future, due to material rigidity requirements, if the material thickness changes, the male mold may become the female mold. The dimensional tolerance of plastic parts must not be less than 10% of the shrinkage rate.

2. Regarding the surface of the molded part: Within the molded material packaging, the visible surface structure of the molded part must be molded where it contacts the vehicle. Whenever possible, the shiny surface of the plastic part must not come into contact with the vehicle's exterior. This is similar to using female molds for bathrooms and laundry rooms.

3. Geometric design: Dimensional stability and surface quality must be considered comprehensively during design. For example, a product's design and dimensional stability may require a female mold, but a product requiring a high surface gloss may require a male mold. Therefore, a molding order uniquely considers both factors to ensure optimal production conditions. Experience has proven that designs that do not meet actual processing conditions often fail.
