CNC Machined UHMW

UHMW is a common plastic known for extreme durability, versatility, and cost-effectiveness. You can also count on UHMW parts to be reliably abrasion, impact, and chemical resistant.

UHMW

Our Ultra High Molecular Weight Polyethylene, or UHMW for short, was crafted as a unique solution for projects that needed durability, low friction, and chemical resistance. That means it’s used most often in wear applications that need a longer lifespan.

UHMW is self-lubricating, which ensures smooth and noiseless operations. Known for its extremely high molecular weight, it features an unsurpassed combination of slickness, toughness, and impact resistance.

Used in a variety of applications

UHMW is also easy to machine with common woodworking tools, one of the contributing factors to its cost-effectiveness. The truly surprising thing about parts made from UHMW is that they often outperform metal parts in specific applications. 

As with other plastics like HDPE, UHMW is an excellent fit for marine construction applications for things like dock fender pads, pile guards, and anti-skid walkways. Similarly, these two materials tend to replace wood in these scenarios and they do not rot, splinter, or corrode like wood.
