Is the production process of plastic mold complicated?

With the development of technology, plastic molds have long been an irreplaceable product in our days. In our real life, plastic products have almost captured various fields. Whether it is the spare parts of the aircraft car and the ship, some of the toothbrush cups that are commonly used in our daily days have plastic shadows. In fact, the plastic products that are commonly used around us are not produced by the manufacturers according to the drawings one by one, but are mass-produced through plastic molds.
Before the manufacturer wants to produce a plastic product, the mold of this product will be prepared in advance. After the mold is finished, the manufacturer can mass produce and manufacture through this mold. So is the manufacturing process of plastic molds messy?
In fact, the manufacturing process of plastic molds is very accurate and messy. Because in the real world, plastic molds have been applied to various plastic products, and many plastic products have to be very accurate in manufacturing, such as plastic bottles. And the manufacture of plastic caps needs to be very precise, because if there is a little bit of non-conformity, it should be impossible to combine. Therefore, in the manufacture of plastic molds, we must pay attention to such problems, we must make the molds very accurate to be able to make quality plastic products. Of course, for those plastic products that are relatively large and relatively inexpensive, there is no too high process requirement. For example, the mold of the plastic basin does not have too strict requirements for the manufacturing process.
