Manufacturing process
Our dedicated manufacturing cells produce Compression Molded Parts from premium engineering fluoropolymer powder stock. After uniaxial preforming in precision tooling, components undergo computer-monitored sintering cycles and diamond-tooled CNC profiling to hold exact drawing dimensions.
Material selection notes
Featuring FDA-compliant virgin engineering fluoropolymer or specialized filled compounds, Compression Molded Parts provides reliable sealing and low-friction motion under continuous operating temperatures up to +260°C. Filler additions enhance mechanical rigidity, wear resistance, and thermal conductivity for heavy mechanical loads.
How to specify your order
To evaluate Compression Molded Parts for your project, submit component PDF drawings and resin requirements. HEMSUN engineers review part geometry, recommend appropriate compression tooling or CNC machining approaches, and provide competitive commercial proposals.
Quality checks and inspection
Quality assurance for Compression Molded Parts includes 100% optical dimensional inspection, digital micrometer verification, CMM coordinate layout testing, and water displacement specific gravity checks according to ASTM D792. High-voltage spark testing up to 80 kV/mm verifies absence of internal pinholes and voids.

Frequently Asked Questions
When is compression molding preferred over machining?
Compression molding suits higher-volume PTFE parts with relatively simple geometry, reducing material waste versus full CNC removal from stock.
What tooling is required for compression molded PTFE?
Custom molds are designed for your part geometry. Tooling cost and amortization are discussed during RFQ for production quantities.
