POM \/ acetal gear family<\/h2>\n

POM\/acetal is frequently evaluated for plastic gearing because of its dimensional behavior and low-friction characteristics, but grade, geometry, mating material and temperature still determine suitability.<\/p>\n

POM can be sensitive to aggressive press fits and to thermal growth relative to a metal shaft. Where the bore is critical, state the shaft material, fit intent and assembly temperature. For dry-running pairs, the mating flank material and finish should be part of wear testing.<\/p>\n<\/section>\n

How to read the product photograph<\/h2>\n

The main image is a photograph of a physical sample or representative component, not a dimensional definition. Resin colour, tooth count, bore or hub features, rack length, inserts and other details can change with the released drawing. Use the photograph to understand the product family; use the controlled drawing, mating interface and agreed inspection plan to manufacture and approve the part.<\/p>\n<\/section>\n

      Common risks for this geometry include grade substitution without rechecking shrinkage or dimensions; service moisture\/temperature outside the approval condition; wear-pair assumptions based on one material only. These are best addressed before the first sample by reviewing the complete mating interface, not by tightening every drawing tolerance.<\/p>\n

      02<\/span><\/p>\n

      Choose material by duty<\/h3>\n

      POM \/ polyacetal \/ acetal Material selection should be checked against load, speed, temperature, moisture or chemicals, lubrication and the required dimensional condition.<\/p>\n<\/article>\n

      03<\/span><\/p>\n

      Freeze the production route<\/h3>\n

      Injection molding or machining according to confirmed product configuration The route should be fixed only after quantity, tolerances, surface requirements and change risk are understood.<\/p>\n<\/article>\n

      04<\/span><\/p>\n

      Agree acceptance<\/h3>\n
