Machined Acetal Description

CNC-machined Acetal is a type of plastic used in high-performance applications because it has strong mechanical and thermal properties. This plastic comes from polyoxymethylene (POM) resin and is known for its stability, low moisture absorption, and resistance to wear, chemicals, and oils.

Acetal is easy to machine and shape, making it perfect for complex parts that require precise dimensions. It is commonly used to make gears, bearings, bushings, and electrical components in the automotive, aerospace, healthcare, and industrial manufacturing industries.

Why should you choose machined Acetal for your project?

Acetal is a popular thermoplastic used in many industrial and engineering projects. Its main benefits include strong mechanical properties, such as high strength and stiffness, and resistance to wear and fatigue.

Acetal also provides good dimensional stability and low moisture absorption, making creating complex parts with precise tolerances easy. It is lightweight, non-toxic, and resistant to many chemicals, which makes it ideal for tough environments that may involve harsh chemicals or extreme temperatures.

In summary, Acetal is an excellent choice for making durable parts that need high strength and exact measurements without losing quality or performance.

Finishes for machined Acetal.

Acetal is a versatile plastic used in many engineering applications because it has several beneficial qualities. It is stiff, has low friction, and maintains its shape well. A critical factor in the production process is choosing the right surface finish. The wrong choice can affect how the final product works and looks.

Acetal can have four finishes: natural, matte, polished, or textured. Each type requires specific tools and methods. For a matte finish, you can use sand or a blast rust removal technique. You use compounds to create a smooth, shiny surface to achieve a polished finish. Special processes create a textured finish. When you choose a finish, consider both practical needs and visual appeal to get the best result for your part.
