Technical plastics replacing metal in machines and automation equipment

In the machine and automation industry, technical plastics are increasingly replacing metal. The benefits are numerous: lower weight, better sliding properties, chemical resistance, lower maintenance costs, and quieter operation. PlastShop delivers semi-finished products to machine builders, contract manufacturers, and maintenance workshops throughout the Nordic region. Our materials are easily processed with conventional CNC machines and lathes.

Requirements and challenges

The material must withstand constant mechanical stress without deforming
Low friction and good wear resistance for moving parts
Dimensional stability at varying temperatures and humidity
Easy processing with CNC, lathe, and milling
Chemical resistance to oils, fats, and lubricants

Recommended materials

POM C / POM H
First choice for precision parts. Low friction, high stiffness, excellent processability

PA6 / PA6.6
Gears, bearings, and sliding surfaces. High wear resistance and good chemical resistance

PE-1000 (UHMW)
Exceptional wear resistance for conveyors, guides, and wear strips

PEEK
High-performance parts that withstand high temperatures and aggressive chemicals

PET
Precision parts with excellent dimensional stability and surface finish

PC
Machine guards and sight glasses. Transparent and extremely impact-resistant

Common applications

Gears and gearboxes

POM and PA6 provide quiet operation, low friction, and long service life without lubrication.

Bearings and bushings

POM, PA6, and PEEK replace metal bearings with lower weight and maintenance.

Conveyors and guides

PE-1000 and PA6 for sliding surfaces, guides, and wear strips on conveyor belts.

CNC-machined parts

POM, PEEK, and PET provide excellent surface finish and tight tolerances in CNC machining.

Why choose plastic?

Technical plastics offer a unique combination of properties that metal cannot match. Plastics are lighter, have naturally low friction (often without the need for lubrication), dampen vibrations and noise, and do not corrode. In many applications, plastics provide longer service life and lower total cost than metal. Additionally, plastics are easier and less expensive to process, resulting in shorter lead times and lower production costs.
