STMC Successfully Completes Cryogenic Deflashing of EPDM Rubber Rings for Client

Recently, STMC undertook a cryogenic deflashing order for a client’s ethylene propylene diene monomer (EPDM) rubber rings. The client delivered a large batch of rubber ring products, requiring efficient removal of flash and burrs without damaging the surface, ensuring smoothness and dimensional accuracy. Leveraging advanced cryogenic deflashing technology and extensive processing experience, STMC successfully completed the delivery, earning high praise from the client.

Stringent Process Requirements

EPDM rubber is widely used in automotive, electronics, and construction industries due to its excellent weather resistance, anti-aging properties, and sealing performance. However, traditional manual or mechanical deburring methods can easily cause deformation or surface scratches on EPDM rubber rings, affecting product yield. The client’s shipment consisted of a large quantity of uniformly sized rubber rings, requiring efficient flash removal while ensuring zero damage.

Solution: Ultra-Low Temperature Cryogenic Deflashing Technology

STMC employed industry-leading cryogenic deflashing technology, completing the task with precision through the following steps:

Scientific Batching: Strict weighing and classification of incoming materials to ensure balanced processing per batch.

Multi-Machine Coordination: Simultaneous operation of multiple ultra-low-temperature cryogenic deflashing machines to significantly improve efficiency.

Parameter Optimization: Adjusted temperature, vibration frequency, and duration based on EPDM material properties to ensure flash embrittlement and removal while maintaining the rubber rings’ elasticity and smoothness.

Full Inspection: Post-processing dimensional and surface checks to ensure 100% compliance with client standards.

Key Technical Advantages

Damage-Free: Ultra-low temperatures embrittle flash, avoiding scratches or deformation from mechanical contact.

High Efficiency: Parallel processing with multiple machines, achieving a daily capacity of XX million pieces, shortening lead times.

Eco-Friendly & Safe: No dust or chemical pollution, aligning with green manufacturing standards.
