Delrin® Plastic Machining

Delrin® 150 is an ideal material for parts that require high stiffness and dimensional stability, low friction, and good chemical resistance. Delrin® plastic also exhibits excellent wear properties in both wet and dry environments, making one of the more versatile engineering plastics available. This material offers excellent machinability, making it ideal for parts that require intricate geometries and/or tight tolerances. Upland Fab has been working with Delrin® acetal for decades. We have the skills and expertise to produce quality parts the first time—and every time!

 

Delrin Acetal Homopolyer vs. Acetal Copolymer

 

Delrin 150 is a homopolymer variation of acetal. Though similar in most aspects, both options do provide unique characteristics that may make them better suited to your specific application. Both “standard” acetal and Delrin acetal are available in a variety of grades, including FDA-approved grades for food-contact applications. Contact Upland Fab to discuss your material requirements.

 

  • Delrin acetal homopolymer exhibits higher strength at room temperature than acetal copolymer, in addition to greater toughness and stiffness.

 

  • Acetal copolymer (standard acetal) offers better overall performance in continuous high heat or hot water environments; it also has lower porosity than Delrin.

 

Experts in Machining Delrin® Acetal

 

When working with Delrin 150, we utilize advanced multi-axis machining capabilities to ensure precise tolerances are met each and every time. Our CNC machining technology provides the precision and repeatability to create complex parts with minimal handling and fixturing. In many cases, highly intricate parts can be completed in a single operation.

 

Using DPD/MBD processes (Digital Product Definition/Model-Based Definition) allows us to work directly from your completed CAD models. This capability reduces manufacturing errors and guarantees high-quality parts at low cost. We provide high quality, cost-effective Delrin plastic parts.
