Acetal Machining
Acetal Machined Parts
Sunhy has a reputation for producing quality screw machine parts from Acetal plastic. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.
Acetal is a versatile low-cost plastic, ideal for parts that require high mechanical strength and rigidity, while machining to very tight tolerances. It has good dimensional stability and chemical resistance, making it long-wearing. Unlike nylon, it has a very low moisture absorption rate, making it suitable for use in wet environments.
Acetal has a machining cost factor of 0.7 when compared to steel 12L14.
