POM Sheets and Rods

Larosi supplies POM sheets and rods in natural color, available from stock for fast delivery. POM is among the most requested engineering plastics for the production of precision mechanical components. POM sheets and rods can be cut to size through our dedicated cutting service, ready for subsequent machining such as milling or turning.

What is POM and why it is chosen for precision mechanics

POM, or polyoxymethylene, is a semi-crystalline engineering plastic also known by the trade name Delrin. Those looking for this material often use the two terms interchangeably, but they indicate the same type of acetal resin.

POM sheets and POM rods stand out for some key characteristics:

• High dimensional stability, even with tight tolerances
• Good sliding properties and low coefficient of friction
• Excellent machinability with traditional machine tools and CNC
• High rigidity compared to other semi-finished engineering plastics

These properties make POM a frequent choice for those producing components subject to continuous movement or repeated surface contact.

POM sheets and rods available from stock

Larosi keeps POM sheets and POM rods in natural color in stock. This choice ensures continuity of supply and uniformity between different batches, avoiding color variations that complicate the planning of recurring orders.

Natural color is not a limitation for most mechanical applications, where function prevails over aesthetics.

For large quantities or non-standard formats, contact us: we check actual availability before confirming the order.

Custom cutting of POM sheets and rods

POM sheets and rods can be cut to size directly by Larosi. We use a Putsch Meniconi SVP 145 vertical saw, designed to ensure precision even on technical materials such as POM.

The cut piece arrives ready for subsequent machining, without scrap to manage in the workshop. Discover how the plastic sheet custom cutting service works, with our transparent three-level pricing model.

Applications: where POM sheets and rods are used

POM is used in numerous areas of industrial mechanics. Among the most common applications:

• Gears and toothed wheels
• Bushings and sliding bearings
• Linear guides and motion components
• Parts subject to constant friction or repeated loads

Thanks to these properties, many mechanical workshops choose POM to replace metal components when weight or noise reduction is needed.

POM vs Nylon (PA6): which material to choose

POM and Nylon (PA6) are often compared because they cover similar applications, but the practical differences are significant.

POM generally offers greater dimensional stability and lower moisture absorption compared to PA6. This makes it preferable for components that require tight tolerances and dimensional consistency over time.

PA6, on the other hand, often provides better impact resistance and greater toughness under dynamic stress conditions.

In summary:

• Choose POM for dimensional precision and sliding properties
• Choose PA6 for impact resistance and greater mechanical toughness

If you are not sure which material is needed for your project, contact us: we will evaluate the specific application together.

POM vs Polyethylene (PE): differences and selection criteria

The comparison between POM and Polyethylene (PE HDPE) also frequently arises among those selecting technical semi-finished products.

POM stands out for rigidity and dimensional precision, suitable for precision mechanical components such as gears or calibrated bushings. PE, on the contrary, offers greater abrasion resistance and better performance in continuous sliding applications or in contact with abrasive surfaces.

The choice therefore depends on the prevailing type of stress in the component:

• Precision and rigidity: POM
• Wear resistance and sliding under load: PE HDPE

Both materials are available from Larosi stock, with the possibility of custom cutting for both types.
