A compression machine is a general term for equipment that applies pressure to shape or form materials. In the plastic manufacturing industry, it refers to machines that mold parts by compressing heated plastic into a mold cavity.

This process is used to produce a range of components, including plastic caps, seals, and custom parts. The machine typically includes a heating system, mold clamping unit, and a press system to shape the material under controlled force.

Compression machines are suitable for both thermoset and thermoplastic materials, depending on the application. Operators can fine-tune pressure levels and mold temperature to achieve the required product specifications.

Industries such as automotive, packaging, and consumer goods utilize compression molding for parts that demand precise shaping and material control.

Maintenance of a compression machine includes checking for uniform heating, ensuring mold cleanliness, and monitoring pressure systems. With proper setup, this machine type supports steady production with minimal waste.
