Compression Molding Services
Thermoset, Rubber & Composite Components
TNK provides precision compression molding services for thermoset plastics, rubber compounds, and engineered composite materials. This process enables the production of strong, durable components with excellent dimensional stability and surface finish.
Our compression molding solutions support prototype development, low-volume production, and full-scale manufacturing for customers across Canada and the United States.
By combining engineering expertise, mold design support, and controlled production processes, we deliver reliable molded components that meet demanding performance requirements.
What is Compression Molding?
Compression molding is a manufacturing process where a pre-measured material charge is placed into a heated mold cavity and compressed under controlled pressure.
During the molding cycle, the material flows to fill the mold geometry and cures into the final component shape.
This process is commonly used to produce high-strength, heat-resistant, and structurally stable components used in industrial and engineering applications.
