Description

Machined Acetal is a type of engineering plastic commonly used in high-performance applications due to its exceptional mechanical and thermal properties. It is a thermoplastic derived from polyoxymethylene (POM) resin and is known for its excellent dimensional stability, low moisture absorption, and resistance to abrasion, chemicals, and oils. It is also easy to machine and fabricate, making it an ideal material for intricate parts and components that require tight tolerances and complex geometries. Acetal is often used in automotive, aerospace, healthcare, and industrial manufacturing industries for applications such as gears, bearings, bushings, and electrical components.

Why should you choose machined Acetal for your project?

Acetal is a popular thermoplastic material with several benefits for various industrial and engineering applications. One of the primary reasons to choose it for your project is its exceptional mechanical properties, as it possesses high strength, stiffness, and resistance to wear and fatigue. Additionally, Acetal offers good dimensional stability, low moisture absorption, and excellent machinability, which makes it easy to manufacture complex parts with tight tolerances. Furthermore, it is lightweight, non-toxic, and has good chemical resistance, making it suitable for use in demanding environments where exposure to harsh chemicals or extreme temperatures is expected. Overall, it is an excellent choice for applications that require parts with tight tolerances, high strength, and durability without sacrificing material quality or performance.

Finishes for machined Acetal

Acetal is a remarkably versatile material used extensively in various engineering applications due to its unique combination of desirable qualities. For instance, this plastic provides exceptional stiffness, low friction, and unparalleled dimensional stability. However, a crucial factor that must not be overlooked during the production process is determining the appropriate surface finish. Choosing the wrong finish could dramatically affect the functionality and aesthetic appeal of the final product.

Acetal can be finished in four ways: natural, matte, polished, or textured. Each technique requires specific tools and methods to achieve the desired outcome. For instance, a sand or blast rust removal technique is effective to produce a matte finish. On the other hand, a polished finish involves using a series of compounds that result in a smooth and glossy surface. Moreover, to create a textured finish, a specific process is necessary. Ultimately, when selecting your desired finish, you must consider both practical and visual considerations to achieve the optimal outcome for your part.
