Polyoxymethylene (POM) Injection Molding
While polyoxymethylene is not something that you might come across in your everyday life, it is an extremely popular material for injection moulded products. The many benefits of polyoxymethylene include:
- Extremely strong
- Retains properties in the temperature range -40°C up to 140°C
- Excellent dimensional stability
- Impressive wear and tear characteristics
- Creates a high-gloss surface
- Low moisture absorption
After reading the characteristics of polyoxymethylene it is not difficult to guess a number of different products which may benefit. These include:
- Gear wheels
- Ball bearings
- Fasteners
- Knife blades
- Locking systems
- Ski bindings
The strength and durability characteristics of polyoxymethylene are very similar to many types of metal, as demonstrated in the above products. This makes it a very popular material when considering the many applications of injection moulding.

The Pros and Cons of POM Injection Molding Materials: Properties, Applications, and Limitations
POM (Polyoxymethylene) is a thermoplastic polymer that is commonly used in injection molding due to its unique properties. POM injection molding materials offer a combination of strength, stiffness, and dimensional stability, making them suitable for various applications. In this article, we will explore the properties, applications, and limitations of POM injection molding materials.
Properties of POM Injection Molding Materials
POM is a high-performance thermoplastic polymer that exhibits the following properties:- High strength and stiffness: POM has a high strength and stiffness, making it suitable for applications that require high strength and stiffness.
- Good dimensional stability: POM has good dimensional stability, meaning it can maintain its shape and size even when exposed to high temperatures or humidity.
- Low friction coefficient: POM has a low friction coefficient, making it suitable for applications that require low friction.
- Chemical resistance: POM is resistant to many chemicals, including acids, alkalis, and alcohols.
Applications of POM Injection Molding Materials
POM injection molding materials have a wide range of applications in various industries, including automotive, consumer goods, and electronics. Here are some of the most common applications of POM:- Automotive parts: POM is commonly used to make automotive parts such as gears, bearings, and fuel system components.
- Consumer goods: POM is used to make a variety of consumer goods, including handles, zippers, and mechanical toys.
- Electronics: POM is used in the electronics industry to make camera parts, printer components, and other electronic devices.
Limitations of POM Injection Molding Materials
While POM injection molding materials offer several advantages, they also have some limitations, including:- Not suitable for high-temperature applications: POM has a low melting point, making it unsuitable for high-temperature applications.
- Poor UV resistance: POM is not UV resistant, meaning it can deteriorate when exposed to UV radiation.
- High moisture absorption: POM has a high moisture absorption rate, meaning it can swell when exposed to moisture.
- Limited color options: POM injection molding materials have limited color options, making it difficult to achieve certain colors.
