Advantages of Acetal (POM) in precision industrial applications

Acetal, also known as POM (polyoxymethylene), is an engineering thermoplastic widely used in industrial environments that demand high precision, durability, and strength. Thanks to its physical and mechanical properties, it has become a reliable solution for replacing metal components in machinery, transportation equipment, and technical devices. At Suimtec, this material is marketed under the name Acetal TEC/PLASTIC, recognized for its dimensional stability and superior technical performance.

One of the main advantages of acetal is its excellent dimensional stability, which allows it to maintain its shape and tolerances even under varying humidity or temperature conditions. This makes it ideal for parts requiring constant accuracy, such as gears, bushings, and moving components. Furthermore, its high mechanical strength and structural rigidity allow it to withstand loads without significant deformation, thus extending the service life of the systems in which it is installed.

Acetal also exhibits a low coefficient of friction, which promotes smooth movement between contacting surfaces. This property reduces frictional wear, decreases the need for lubrication, and improves the overall performance of the mechanical system. Furthermore, its chemical resistance to oils, solvents, and fuels allows its use in harsh industrial environments and in sectors such as automotive, pharmaceutical, and food.

Another notable feature is its excellent machinability. Acetal is easily machined on conventional lathes and milling machines, offering precise results similar to steel, but with less weight and no risk of oxidation. This allows for the manufacture of customized components, optimizing costs and production times.

Among its most common applications are gears, pinions, bearings, valves, bushings, sprockets, valve seats, rollers, and structural supports. Its use is key in industrial processes where operational reliability is paramount.

Suimtec's Acetal TEC/PLASTIC is available in sheets and bars, tailored to customer needs and backed by expert technical support. It is a modern, efficient, and durable alternative to metal for operations requiring precision and strength under demanding industrial conditions.
