When it comes to purchasing plastic molds, many people have encountered such confusion:Despite the apparent similarity in mold appearance and dimensional parameters between two apparently similar molds, the price difference can be thousands or even tens of thousands. Choosing the cheaper one often leads to frequent issues during mold testing, burrs, shrinkage, and warping during mass production, resulting in mounting mold modification costs in the later stages. On the other hand, choosing the more expensive one raises concerns about exceeding the budget and being questioned for the premium price. In fact, plastic molds are never products that are simply "judged by appearance and price". Instead, they are non-standard industrial products that are evaluated based on their structure, materials, craftsmanship, and quality control.
