Today, parts need to be more precise. Traditional trimming methods often can’t meet the high standards for polyurethane (PU) shock absorbers.
To solve this, STMC now offers cryogenic deburring services for PU shock absorbers. We use advanced technology to help improve your product quality.
PU material is great for shock absorption. But after molding, it often has rough edges (flash). These edges look bad. They can also cause parts to fit poorly, wear out faster, and reduce the equipment’s lifespan.
What is Cryogenic Deburring?
It’s a new way to clean parts. It is fast, clean, and safe for the product.
Here’s how it works:
-
We freeze the parts at a very low temperature using liquid nitrogen. This makes the rough edges brittle.
-
We then spray soft media at high speed. This removes the brittle edges cleanly.
Why choose our service?
-
No Damage: The main part of the product stays perfect.
-
Saves Time: We can process many parts at once, much faster than by hand.
-
Clean & Green: No chemicals or harmful dust.
-
Saves Money: Less manual work and fewer wasted parts lower your costs.
