Solution Description
Expert make injection moulding POM gears
Description:
POM (Complete-name: CZPT formaldehyde), is a CZPT plastics of CZPT -side-chain, high density, substantial crystalline and linear polymer, which is praised “Plastic Steel”, and has comprehensive exceptional performances, such as: use-resistance, large hardness, anti-impregnant, great rigidity (Tensile modulus of elasticity), chemical steadiness, isolation resistance and dimensional stability.
POM has broadly applied in CZPT cellular industries, electronic and electric goods, commodity, pipeline & fittings, precise equipment and so on, which can be instead of the bronze, Zinc, tin and other metals.
Except POM-H, is typically copolymerized with ethylene oxide collectively, in get to avoid the melting of POM material in the large temperature. POM-H has the far better performances than POM-C in its substantial crystalline, mechanical strength and rigidity.
And POM-C has the far better performances than POM-H in its reduced melting stage, temperature steadiness, fluxion characteristic and machining capacity.
Father a lot more, POM-H+PTFE, which is made from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the low co-productive of frication, very good lubrication, wear-resistance, CZPT -creepage resistance.

EP also sells equipment tooth measuring products referred to as equipment gauges! Gear gauges minimize problems, saving time and income when determining and ordering gears. These pitch templates have 9 groups to determine all normal pitch measurements: Diameter Pitch “DP”, Circle Pitch “CP”, External Involute Spline, Metric Modulus “MOD”, Short Tooth, Good Pitch, Coarse Pitch and Remarkable Pitch .
