UHMW Machined Parts
Cox Manufacturing has a reputation for machining quality parts & high volume swiss screw machining from UHMW. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.
Ultra-High Molecular Weight polyethylene (UHMW) is a high-density plastic, ideal for screw machine parts that require extremely high resistance to wear and abrasion. It has the highest impact strength of any thermoplastic and is highly resistant to most corrosive materials. UHMW is self-lubricating and performs well in extraordinarily low temperatures, but begins to soften in higher temperatures. Unlike nylon, it has a very low moisture absorption rate, making it suitable for use in wet environments.
Ultem has a machining cost factor of 0.7 when compared to steel 12L14.
