Precision Seal Trimming Solutions for Global Manufacturers

Where Sealing Performance Begins — At the Edge

As engines evolve toward higher efficiency, longer service life, and stricter emission standards, the reliability of automobile oil seals has never been more critical. One often overlooked but decisive factor in seal performance? The precision of the trimming process.

At INTER-CHINA MACHINERY -TrimTech Sealing Solutions, we specialize in advanced oil seal trimming machines designed to ensure every seal leaves the production line with a clean, accurate, and consistent edge — because even a 0.1mm burr can lead to leakage, customer returns, or field failures.

We don’t just sell machines — we deliver precision, productivity, and peace of mind.

Why Precision Trimming Matters

Oil seals made from HNBR, FKM (Viton), ACM, or PTFE are highly engineered components. After molding or injection, they often carry flash or uneven edges that must be removed before assembly. Poor trimming leads to:

❌ Lip damage causing early oil leakage
❌ Inconsistent dimensions affecting fit and sealing pressure
❌ Surface micro-cracks initiating premature failure
❌ Rejection by OEMs due to non-compliance with IATF 16949

Our trimming systems solve these issues with controlled, repeatable, and material-optimized cutting technology — essential for both mass production and high-reliability remanufacturing.
