Plastic mold is a tool for producing plastic products. It is composed of several groups of parts, and there is a molding cavity within this combination. During injection molding, the mold is clamped on an injection molding machine, and the molten plastic is injected into the molding cavity. The plastic cools and takes shape in the cavity, after which the upper and lower molds separate. The product is ejected from the cavity by the ejection system and leaves the mold. Finally, the mold closes again for the next injection molding, and the entire injection molding process is carried out cyclically.

Selecting the right plastic mold material is crucial for performance, durability, and cost-efficiency. Key factors include polishing performance, thermal stability, machinability, surface hardness, wear and corrosion resistance, and budget. Common choices range from P20 and NAK80 for polishability, H13 and S136 for heat resistance, to D2 and 1.2379 for wear-heavy parts. Material decisions should be based on the application, production volume, and surface requirements, supported by mold flow analysis and prototype testing.
