Compression Mold
What is Compression Mold?
A compression mold is a tool used in the manufacturing process of compression molding. It consists of two or more mold halves that are closed under pressure to shape materials such as plastics, rubber, and composites. Compression molds are typically made of metal and can withstand the high pressures and temperatures required for the molding process. They are used to produce a wide range of products with precise dimensions and surface finishes, including automotive parts, electrical components, and consumer goods.

What is Compression Mold Process?
Compression Mold Process
The compression molding process involves the following steps:
- Material Preparation: The material, typically in the form of pellets, powders, or preforms, is prepared and placed into the mold cavity.
- Mold Closure: The two halves of the mold are closed under high pressure, often using a hydraulic press, to compress the material into the desired shape.
- Heating: Heat and pressure are applied to the mold to soften the material and facilitate flow into all areas of the mold cavity. The temperature and pressure levels are carefully controlled based on the material being molded.
- Cooling: Once the material has taken the shape of the mold cavity, the mold is cooled to solidify the part. Cooling may occur naturally or be accelerated using cooling channels within the mold.
- Part Ejection: After the part has sufficiently cooled and solidified, the mold is opened, and the finished part is ejected from the mold cavity. Ejection pins or mechanisms may be used to facilitate part removal.
The compression molding process is commonly used to manufacture a wide range of products, including automotive components, electrical insulators, appliance parts, and consumer goods.
