POM CNC Machining

Polyoxymethylene (POM for short) also known as acetal, delrin, is an engineering plastic with excellent comprehensive properties and is often used to manufacture various precision parts. Below introduces the characteristics, processes and applications of POM materials:

High strength and rigidity

POM has high hardness and rigidity, making it an ideal structural engineering material.

Low friction and wear-resistant

POM can withstand long-term repeated loads without fatigue damage and is suitable for custom gears, bushings, and bearings, and other transmission parts.

Chemical resistance

It has good chemical stability to most inorganic acids, alkalis, alcohols, solvents, and fuels etc. POM is commonly used in manufacturing valves, corrosion-resistant compressor pistons, pump parts, fuel system components etc.

Self-lubricating property

It has a low friction coefficient under dry friction conditions and is suitable for manufacturing bearings, etc.

Easy Machinability

The simplicity of POM being cnc turned, milled, drilled, molded making it easily precision machined into parts with complex shapes.

Low water absorption and dimensional stability

The processed POM parts are dimensional stable and have a smooth surface. POM parts holds its size and shape even during changing humidity conditions, it does not suffer from moisture-related problems like swelling or warping.

Benefits of CNC Machined POM Parts

Easy design verification and modifications:

CNC machining enables customers to verify their precision CNC pom parts design quickly, making design modifications cost-less and quicker than injection molding.

Precision and Consistency in quality:

CNC machining allows both precision and complex geometry, with easy machinability of POM material, CNC machining pom parts are high precision and consistent in quality, making it ideal for either small or large-scale aerospace or medical parts production.

Time saving:

At HuaRuiDa, CNC machined parts usually features Ra1.6 or 0.8µm, thus CNC machined POM parts requires less post-processing for its easy machinability, helping customers open the market faster at a competitive cost.
