POM is a popular material for CNC machining. Here are some common types of POM we can provide.

Acetal Copolymer (POM-C)

Acetal Copolymer, commonly known as POM-C, is a thermoplastic material that combines the properties of polyoxymethylene (POM) and polyacetal. It is an extremely versatile and strong material ideal for applications that require high strength, chemical resistance, low moisture absorption, good dimensional stability and wear resistance. POM-C has excellent mechanical properties over a wide range of temperatures and can be used in applications where temperatures range from -40 to +120 °C.

Acetal Homopolymer (POM-H)

Acetal Homopolymer (POM-H) is a thermoplastic material used in many industries. It is well known for its excellent machinability, low friction properties, and high wear resistance. POM-H is an excellent balance between stiffness and impact strength and can also be used in high-intensity applications. It has excellent chemical resistance to hydrocarbons, solvents, alcohols, dilute acids, and bases. It is also resistant to microbial growth and hot water sterilization.

Surface Finishes Options For POM Parts

There are several finishing options available for POM CNC machining parts. Some of the most common finishing options include:


Painting is a popular finishing option for POM parts. It allows you to add color and texture to the surface of the part.

Powder coating

Powder coating involves applying a dry powder to the surface of the POM part and then heating it to form a hard, durable finish.


Why Choose Our POM CNC Machining?

1. Increased accuracy and repeatability 

We can produce machine POM parts using computer numerical control (CNC) technology with extreme precision and consistency. This is ideal for applications where tight tolerances must be met, or identical parts must be reproduced regularly.

2. Greater flexibility 

With Our CNC machining, it’s easy to quickly change the design of a part or produce a small batch of custom POM precision parts. This flexibility can save time and money, especially compared to the cost of tooling for traditional manufacturing methods.

3. Reduced waste

Our CNC machining produces little scrap POM material, as each part is created from a solid block of material (known as “stock”). Any small scraps that remain can be recycled back into the production process.

4. Versatile applications 

CNC machining can create a wide variety of POM parts and products. Whether you need rapid prototyping or mass production for POM parts, we can help you achieve the desired results.

Machined POM Parts Applications

POM (Polyoxymethylene) is a high-performance engineering plastic that is widely used in various applications. Some of the most common applications of machined POM parts include:

1. Automotive industry: POM parts are often used in automotive applications due to their excellent resistance to wear, abrasion, and chemicals. They are commonly used in fuel systems, door handles, gears, and other components.

2. Aerospace industry: Machined POM parts are used in aerospace applications due to their excellent strength-to-weight ratio and resistance to impact and fatigue. They are often used in aircraft interiors, control panels, and other components.

3. Medical industry: POM parts are widely used in medical devices and equipment due to their biocompatibility, chemical resistance, and durability. They are commonly used in surgical instruments, implants, and diagnostic equipment.

4. Electronics industry: Machined POM parts are used in electronics applications due to their excellent electrical insulation properties and dimensional stability. They are often used in connectors, switches, and other components.

5. Consumer goods industry: POM parts are commonly used in consumer goods such as toys, sporting equipment, and household appliances due to their toughness, impact resistance, and ease of machining.

Overall, machined POM parts are ideal for applications that require high strength, durability, chemical resistance, and dimensional stability.

What are the benefits of CNC Machining POM(Delrin/Acetal)?

1.  POM CNC machining is an effective way to process engineering plastics. It requires a lower cost than other engineering plastics, making it an attractive option for many companies. POM machining can create highly precise parts with tight tolerances and complex geometries. It is also resistant to corrosion and abrasion, making it suitable for harsh environments. 

2. POM can replace traditional metal materials in CNC machining parts service. It is a thermoplastic with high tensile strength and good dimensional stability, making it an ideal choice for applications such as electronic, mechanical, instrument, automobile, building materials, agriculture, medical, sports, daily light industry, etc., requiring precise tolerances and low friction performance.

3. POM has outstanding machinability and excellent comprehensive performance, including:

  • Great wear resistance
  • High strength, fatigue strength, and rigidity
  • Good electrical properties & insulation
  • Good resilience, vibration absorption, noise reduction
  • Strong organic solvability and low water absorption
  • Dimensional stability
  • Low friction and ideal lubrication


POM (Polyoxymethylene), also known as Delrin and Acetalis, is an engineering thermoplastic that has a variety of applications in industrial and commercial settings. POM plastic has a high melting point and good thermal stability. It also has good electrical insulation properties and impressive dimensional stability. Its mechanical properties make it ideal for use in components that require precise machinings or tight tolerance requirements, such as gears and bearing surfaces. Additionally, its wear resistance makes it suitable for use in parts that experience high-speed abrasion or contact stress. Its chemical resistance makes it useful for automotive applications where exposure to fuel is a factor.

CNC machined POM parts provide many benefits to the manufacturing industry. With CNC machining, parts can be precisely cut with high accuracy and repeatability, saving time and money in the production process. CNC machined POM parts have superior surface finishes compared to other materials such as aluminum or steel, giving them better aesthetics and longer life cycles for end products. CNC machining is a cost-effective solution when it comes to producing small batch sizes of parts with complex shapes and tight tolerances.

Nylon is a strong and durable plastic that can be used for many applications, such as medical devices, automotive parts, clothing, and more. It’s lightweight yet strong enough to withstand wear and tear. Nylon is resistant to water and chemicals, making it a great choice for outdoor products like tents or backpacks that are exposed to the elements. However, when it comes to strength, Delrin is superior. Delrin has superior mechanical strength and stiffness compared to nylon but with less weight. It can also withstand higher temperatures than nylon and has better chemical resistance than most plastics. Delrin also offers excellent fatigue resistance, meaning it can withstand repeated stress without cracking or breaking over time. 

Custom CNC POM parts have a variety of applications in many different industries. These parts are most commonly used in the automotive and aerospace industries, where they are often used for components such as engine blocks, wings, and landing gear. They can also be used to create precise and intricate parts for medical devices and equipment or for industrial machinery and tools. CNC POM parts are also popular for use in the electrical industry due to their low cost and high accuracy. Because these parts can be custom-made to exact specifications, they can be used as replacement pieces for various machines or as replacements for vintage models that are no longer produced. 

When choosing the best plastic material for the CNC machining process, it is important to consider the mechanical and physical properties of the material. Factors such as stiffness, strength, hardness, thermal stability, and surface finish should be taken into account when selecting a suitable plastic. You should also consider how easy or difficult it will be to machine the material in terms of its tendency to stick to tools and whether it can be cut with blades. Furthermore, you may need to consider whether the plastic is able to accommodate any post-processing treatments that are needed. The cost is an important factor when selecting a plastic material for CNC machining, as some materials may require expensive tooling or special cutting techniques.
