POM: The Most Useful Material in the Workshop?

POM: The most useful material in the workshop?

When we talk about engineering plastics in the workshop, POM (polyoxymethylene) is often overshadowed by other materials, such as PE-HD or PA6G. But we believe that POM is one of the most versatile and useful materials in our range. Let’s take a closer look at POM and explore what makes it so popular for precision machining.

POM C versus POM H: What’s the difference?

POM is available in two main variants: POM C and POM H. The main difference between them is the polymerisation process. POM C is a copolymer, whilst POM H is a homopolymer. This affects the material’s properties and areas of application. For example, POM C has a higher hardness and better resistance to wear, whilst POM H has a higher tensile strength.

But what does this mean in practice?

When carrying out precision machining, it is often important that the material can be machined with high precision and without deformation. Both POM C and POM H are excellent choices, but with different strengths and weaknesses. Can we always rely on POM to meet the requirements for precision and reliability?

Machinability and dimensional stability

POM is known for its excellent machinability. It can be cut, milled and drilled with ease and produces short chips that are easy to handle. We offer POM cutting services in various dimensions. This makes it an ideal material for the manufacture of complex parts and precision components. POM is not only easy to machine, but also highly dimensionally stable. This means that it does not deform or change shape during machining or use, which is crucial for many applications.

An important property of POM is its low friction. This makes it suitable for the manufacture of parts subjected to high loads and sliding, such as bearings and valve seats. How can we best utilise this property in our manufacturing? Are there any particular challenges or considerations to bear in mind when working with POM?

Typical applications for POM

POM is often used in the manufacture of precision components that require high reliability and stability. Some examples of common applications are:

• Gears and transmission components
• Bearings and bushings
• Valve seats and seals
• Components for medical and laboratory equipment

These are just a few examples of the many applications in which POM can be used. What makes POM such a popular choice for these applications? Is it the combination of low friction, high hardness and excellent machinability that makes it suitable for precision machining?

Why is POM a good choice for precision machining?

Many factors come into play in precision machining. We must consider the material’s properties, machinability, dimensional stability and cost. POM is often a good choice. But why?

We believe it is a combination of all these factors. It is a material that can be machined with high precision, has low friction and high hardness, and is cost-effective. Do you have any experience of working with POM, and what do you consider to be its main advantages and challenges?
