POM, also known as acetal or polyacetal, is a thermoplastic material known for its exceptional strength, stiffness, toughness, and low coefficient of friction. Delrin belongs to the wider category of POM plastics and is a particular brand of acetal. Despite different manufacturers, Delrin and other POM acetal materials share similar properties. POM is commonly used as a substitute for metals in mechanical parts due to its high wear resistance, low friction, and resistance to abrasion, chemicals, and moisture. Additionally, it can withstand a wide range of temperatures.
POM can be CNC machined into complex shapes and is available in various grades with different properties, such as enhanced stiffness or improved chemical resistance, to suit different applications. It is used in a wide range of industries, including automotive, electrical, medical, and consumer goods.
There are several popular grades of polyoxymethylene (POM), each with different properties that make them suitable for specific applications. Here are some of the most commonly used grades of POM:
The most common POM grade used for manufacturing is acetal copolymer (POM-C), also known as polyoxymethylene copolymer. POM-C has a good balance of mechanical properties, including high stiffness, low friction, and excellent dimensional stability. It is also resistant to moisture and chemicals, making it suitable for use in a wide range of applications, including automotive, medical, and consumer products.
POM homopolymer (POM-H) is another grade of POM that has higher stiffness and hardness than POM-C, but it is also more brittle and has lower impact strength. POM-H is often used in applications that require high stiffness and strength, such as gears and bearings.
UV stabilized POM is typically used in outdoor or UV-exposed applications where prolonged exposure to sunlight or UV radiation can cause the material to degrade or discolor over time.
This is a specialized grade of POM that is approved for use in contact with food and beverages. It is formulated to meet stringent food safety regulations and does not contain any harmful substances that can leach into food.
Material selection can be the difference between success and failure for any project. Educate yourself on material properties to make sure you use them in a way that brings optimal results.
|Density (g /cm3)||Rockwell Hardness||Tensile Strength, Yield||Elongation at Break||Tensile Modulus||Softening Temperature||Friction Coefficient|
|POM||1.39-1.43||135 MPa||63 MPa||27 %||2600 Mpa||150℃||0.35|

There are several benefits to CNC machining Polyoxymethylene (POM):
The complexity and size of the POM part can impact the machining time and cost. Optimize the part design by reducing the unnecessary features and tight tolereance can help to reduce machining time and costs.
Using larger batch sizes can help reduce the cost of CNC machining POM parts by optimizing machine time and reducing setup costs associated with changing tools and fixtures between different jobs.
Optimizing the machining parameters, such as cutting speed, feed rate, and depth of cut, can help to reduce machining time and improve part quality. Choosing appropriate parameters can also help to prevent overheating and material degradation.
Choosing a reputable and experienced CNC machining company like AT-Machining can help to ensure that the POM parts are produced efficiently and cost-effectively. A good supplier can provide expertise in material selection, part design, and machining optimization, which can help to reduce costs.

POM (Polyoxymethylene), also known as Acetal or Delrin, is a thermoplastic material known for its high stiffness, strength, and wear resistance. It is commonly used in automotive, electrical, and consumer goods applications due to its excellent mechanical properties and dimensional stability.
while both POM and ABS can be CNC machined, POM, is generally considered to be a better material for this process due to its high dimensional stability, hardness, and low coefficient of friction, which make it easier to machine and produce high-precision parts
POM is approved for use in food contact applications by regulatory agencies such as the FDA and the European Food Safety Authority. This means that POM is considered safe for use in food packaging and processing equipment, and will not leach harmful chemicals into food or beverages
In terms of machining, aluminum is a bit more challenging to machine than POM because it is metal and can be more difficult to cut and shape. However, aluminum can also produce a high-quality surface finish and can be machined to very tight tolerances, making it a good choice for applications that require high precision.
POM (polyoxymethylene) and nylon are both strong and durable thermoplastics that have a wide range of industrial applications. In general, POM is considered to be stronger and more rigid than nylon, while nylon is more flexible and has better impact resistance.
