Whether your POM injection molding project is time-sensitive, requires high precision, is short project run related, or highly complex, Fathom can deliver. Injection molding is just one of many manufacturing technologies offered by Fathom. Get started today.
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.
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.
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.
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.
SURFACE FINISH | GUIDE | TYPICAL APPLICATIONS |
---|---|---|
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 |

A: Yes, Fathom offers injection molding services.
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.
