How to ensure the quality and safety of plastic molds
1. High requirements for machining accuracy
Usually the mold is composed of a die, a punch and a mold base, and some can also be multiple assembled modules. In this way, the combination of upper and lower molds, the combination of inserts and cavities, and the splicing of modules all require high machining accuracy. The dimensional accuracy of precision molds is generally in the micron level.
2. Complex shape
For some products such as car covers, aircraft parts, toys, household appliances, etc., the surface of the shape is composed of a variety of curved surfaces, so the cavity surface of the mold is more complicated. Certain surfaces must be processed mathematically.
3. Small quantity
Module production is not mass production, and often only produces a sum of money.
4. Multi-process
In the process of mold processing, many processes such as milling, boring, drilling, reaming, and tapping are always used.
