What is Polyoxymethylene (POM)? / /

Polyoxymethylene (POM) is a popular material for injection molding. Sometimes known as acetal, polyacetal, polyoxymethylene glycol, polymeylene glycol, or polyformaldehyde, POM liquifies at its melting point and is low friction material. POM is ideal for applications that require strength, durability and hardness.

Benefits of Polyoxymethylene (POM) Injection Molding / /

Polyoxymethylene (POM) has many ideal properties. POM has good wear, chemical, and heat resistance. Additionally, it is favored for its rigidity and durability are needed. It has excellent dimensional stability and is resistant to water absorption and chemical compounds. Applications of POM include zippers, pulleys, medical equipment, gears, sliding mechanisms, etc.

POM Injection Molding Properties and Conditions / /

When designing for an injection molding project utilizing POM, several important factors must be considered. In its homopolymer form, POM has excellent hardness and tensile strength. In its copolymer form, POM has desirable thermal stability and chemical resistance. In its solid state, POM is non-toxic and can be used for food equipment and applications. Polyoxymethylene has a melting point of 356 to 446 degrees Fahrenheit and a mold temperature of 122 to 221 degrees Fahrenheit. POM’s tensile strength is ~9000 psi, hardness level is R80, and flexural modulus is ~265000 psi.

Polyoxymethylene Injection Molding Finishes / /

Once a part has been injection molded, it is moved to finishing. The finishing stage can change a part’s appearance or add physical properties. Here are some of the finishing processes offered by Fathom.

Standard No Machine Mark Tool Marks Removed Low Cosmetic
SPI-C1 600 Stone Low Polish Parts
SPI-B1 600 Grit Paper Medium Polish Parts
SPI-A2 Grade #6 Diamond High Polish Parts
SPI-A1 Grade #3 Lens or Mirror
IM-1 Light Bead Blast Need 1 Degree Draft Angle
IM-2 Medium Bead Blast Need 1.5 Degree Draft Angle
IM-3 Heavy Bead Blast Need 3 Degree Draft Angle

Polyoxymethylene Injection Molding FAQs / /

Q: Does Fathom offer injection molding?

A: Yes, Fathom offers injection molding services.

Q: What is injection molding?

A: Injection molding is a manufacturing process commonly used for plastic parts. During injection molding, molten plastic is injected into a two-part mold using high pressure. Once the part has cooled inside the mold, it is ejected. The part may or may not require a secondary finish.

Q: Is Fathom ISO certified?

A: Fathom’s certifications include ISO 9001:2015, ISO 9001:2015 Design, and ISO 13485:2016. For site-specific certifications, please visit https://fathommfg.com/fathom-manufacturing-certifications.
