Ertacetal® POM Rods for Engineering

POM rod, also known as polyoxymethylene rod or stainless steel rod, is a solid cylindrical material made of high-density and high crystallinity thermoplastic engineering plastics. It is made by polymerizing formaldehyde monomers (or trimeric formaldehyde) and has excellent mechanical properties, dimensional stability, and chemical corrosion resistance, widely used in industrial manufacturing. POM rods are usually presented in white, black, or other customized colors, with a smooth surface and high dimensional accuracy, which can meet the processing needs of precision parts.

polyoxymethylene rod

Specific application areas and components

Machinery and equipment

Gears and bearings: replace metal gears, reduce noise and friction losses, suitable for textile machinery and printing machinery.

Guide rails and sliders: Linear motion systems used in CNC machines and automated production lines, providing high wear resistance and stability.

Electronics and Electrical

Connectors and sockets: resistant to insertion and extraction, arc resistance, and meet the requirements of high-frequency signal transmission.

Insulation support: used for the internal structure of circuit breakers and relays to ensure electrical isolation.

Automotive industry

Safety system components, such as seat belt buckles and window lifting mechanisms, must be resistant to fatigue and impact.

Fuel system: Fuel pump gears, injector components, resistant to fuel corrosion and have good sealing performance.

Industrial automation

Robot joints: Lightweight design while ensuring high load capacity.

Conveyor Belt Guide: Food grade POM rods can be used for conveyor lines in clean environments.

Medical devices

Surgical instrument handle: Complies with biocompatibility standards (such as ISO 10993), with a smooth surface that is easy to disinfect.

Precision instrument casing: resistant to chemical corrosion, suitable for laboratory equipment.

Other fields

Consumer goods: Small precision components such as eyeglass frames, zipper heads, stationery fixtures, etc.

Building materials: door and window pulleys, furniture hinges, balancing strength and noise reduction effects.

Precautions

Processing restrictions: Avoid prolonged high-temperature processing to prevent material degradation; Drying treatment is required (moisture content<0.1%).

Environmental adaptability: Long term use in humid environments may result in slight moisture absorption. It is recommended to apply a protective layer.

Color selection: Black POM rods are usually added with carbon black for UV resistance, while white or other colors require confirmation of weather resistance.
