CNC Machining POM

CNC Machining POM

POM (also known as polyoxymethylene) is a synthetic thermoplastic polymer. It has a good balance between mechanical properties and cost, and is widely used in the manufacture of gears and bearings. POM has excellent wear resistance, low friction coefficient, and good chemical resistance, and is suitable for CNC machining. The POM parts made by CNC machining can be used in many fields, such as automotive, aerospace, food and beverage, and medical.

If you are looking for a POM CNCmachining factory in China, YS Rapid is pleased to provide you with custom CNC Machining Parts from POM/Delrin material, we provide various Delrin POM machining including POM CNC milling, Delrin CNC turning, POM gear hobbing, etc.

Guide For Delrin / POM Plastic CNC Machining

As one of plastic machining materials, Polyoxymethylene homopolymer (POM) is an impact and abrasion resistant semi-crystalline thermoplastic used in a wide variety of machining applications. With its excellent material properties and high machinability, POM is very popular with product designers and CNC machinists.

POM is opaque in nature, but POM is available in a variety of colors. It has a density of 1.410-1.420 g/cm3, a crystallinity of 75-85%, and a melting point of 175°C.

POM is well suited for CNC machining such as POM milling and POM Lathing. It can also be cut with a laser cutting, and its pellets can also be used in injection molding and plastic extrusion.

The Characteristics of POM CNC Machining Materials & the Advantages of POM CNC Machining Parts.

Electrical characteristics

POM has excellent thermal insulation properties and also has excellent mechanical strength. POM is a material that is very suitable for electronic components.

CNC POM machined parts are precision mechanical parts that can also withstand substantial electrical stress, making them suitable for use as high voltage insulators. Its low moisture absorption also makes it an excellent material for keeping electronic components dry.

Mechanical strength

POM has a tensile strength of 7000-9000 PSI, is very hard, has strong toughness, and is less dense than metal. POM CNC custom machined parts are suitable for lightweight parts that need to withstand high pressure.

Anti-fatigue

POM is a very durable material with excellent resistance to fatigue failure in the temperature range of –40° to 80°C. In addition, its fatigue resistance is less affected by moisture, chemicals or solvents. This characteristic makes it an ideal material for CNC machining parts that need to withstand repeated impact and stress.

Impact resistance

POM can withstand instantaneous impact without failure, mainly because it has extremely high toughness, and specially treated POM can provide better impact resistance.

Good dimensional stability

Dimensional stability measures a material's ability to retain its normal dimensions after exposure to pressure, temperature, and other conditions during processing. POM does not deform during processing, is suitable for machining, and can achieve precise tolerances.

Friction properties

Moving mechanical parts are usually lubricated to reduce the friction they create when they rub against each other. POM machined parts are inherently slippery and require no lubrication. This feature can be used as part of machinery where external lubricants may contaminate the product, such as food processing machines.

Sturdy

The high tensile strength and durability of POM make it a suitable material for high stress applications. POM machined parts are so hard that they can even be used as a replacement for steel and aluminum machined parts.

Moisture-proof

Even under the most humid conditions, POM absorbs very little water. This means it maintains its structural integrity and dimensional stability even in underwater applications.

Creep resistance

POM is a very tough material that can withstand a lot of pressure without breaking. This outstanding durability enables POM's machined parts to be used in many industries.

electrical insulation

POM is an excellent insulator. Due to this characteristic, POM machinery parts are used in many electronic products.

Disadvantages of POM materials

Low Adhesion: Due to its chemical resistance, POM does not adhere well to adhesives, resulting in difficult bonding. This also makes it difficult for POM machined parts to do surface treatment such as painting.

Flammable: POM is not self-extinguishing and will burn until there is no more oxygen. Fighting a POM fire requires a Class A fire extinguisher.

Heat Sensitivity: Machining POM parts at high temperatures can cause distortion.
