Round Rod in POM C FG 450x1050 mm natural

POM C FG is the food grade version of POM C, made for direct contact with food under both the EU and the FDA regulations. Mechanically and thermally it is the same acetal copolymer as standard POM C, but produced and certified for the food industry. It also means the material is traceable through production, something workshops appreciate when they have to show how a turned part is documented.

Technically the material has a density of 1.41 g/cm³ and handles continuous operation at 105 degrees. The lowest working temperature is -40 degrees and the water absorption sits at a low 0.8 percent. The fire rating is HB. The coefficient of friction against stainless steel is low, the wear is even and the material is tougher than POM H.

The round rod format is the most common starting material for turned parts in food and packaging machines. Typical parts made from POM C FG round rod:
- Bushings and sleeves in belt conveyors
- Gears and belt pulleys in drive units
- Support rollers and guide arms in bottle and can handling
- Dosing bushings and shafts in filling machines
- Guide pins and studs in capping stations

The standard color is natural (slightly yellow white). Blue shows up for workshops that follow the HACCP principle that food contact surfaces should be visually distinguishable from the food; a chip broken off in a blue color is spotted immediately during a visual check on a receiving line.

Chemically POM C FG stands up to the cleaning agents that dominate the food industry: alkaline foam washes, mildly chlorinated disinfectants and hot process water. Strong acids and powerful oxidizers break the material down, so stay with the cleaning programs that your cleaning agent supplier recommends for POM. With hot steam cleaning the temperature has to be limited to short exposures below 120 degrees.

In turning, POM C FG behaves like standard POM C: sharp inserts, high cutting speeds, good chip clearance. The chip tends to come out long and should be broken mechanically or by pulsing the feed. The material gives a fine surface straight off the lathe, and the tolerances hold over time because POM C has low creep and few built-in stresses. Grinding and polishing are rarely necessary.

Standard dimensions in round rod start around 6 mm and run up to large diameters for big bushings and rollers. We cut rod to measure; always leave a couple of millimeters extra on the length for facing and finishing. For larger runs we can supply it cut with chamfered ends.

At 450 mm in diameter and 1050 mm in length, this heavy natural rod is a blank for large turned parts with food approval.
