POM W2320-0035LEV, POM W2320-0038, POM W2320-003, POM W2320-003RO

POM raw materials are widely used to manufacture various sliding and rotating mechanical parts, gear, lever, pulley, sprocket, especially suitable for bearings, hot water valves, precision metering valves, chain rings and rollers of conveyors, flowmeters, internal and external handles of automobiles, cranks and other window rotating machinery, oil pump bearing seat and impeller gas opening. Valve closing, electronic switching parts, tight solids, wiring column mirror mask, electric fan parts, heating plate, instrument button; bearing of audio and video tape; various pipelines and agricultural sprinkler irrigation systems and valves, sprinklers, taps, bathtub parts; switch keyboard, butt***, audio and video tape reels; temperature control timer; power tools, courtyard Parts for garden finishing tools, surfboa***, sailboats and sledges, watch micro gears, frame accessories for sports equipment and backpacks with various ***les, fasteners, lighters, zippers, ***les, cardiac pacemakers in medical devices, artificial heart valves, apex vertebrae, prostheses, etc. POM W2320003U NC, POM W2320-U03, POM W2320-U035-LEV, POM Z2320003, POM Z23200035

It can replace most non-ferrous metals, automobiles, machine tools, instrumentation internals, bearings, fasteners, gears, springs, pipes, conveyor belt accessories, water cookers, pump shells, water leakers, taps, etc. POM 7054, POM 7510, POM 7513, POM 7520, POM 7554, POM 8520, POM 8554, POM 9054, POM 9054, etc.

Process features:

(1) POM does not need to be dried before processing, and it is better to preheat during processing (about 80 C), which is good for the stability of product size., POM CF452, POM CF454, POM EF450, POM EF500

(2) The processing temperature of POM is very narrow (0-215 C). It will decompose when the residence time in the barrel is slightly longer or the temperature exceeds 220 C, resulting in strong stimulating formaldehyde gas., POM FA405, POM FS410, POM GA510

(3) Pressure holding pressure of POM material should be larger (similar to injection pressure) to reduce pressure drop. Rotation speed of screw should not be too high and residual quantity should be less; POM GA520, POM GN455, POM GN705, POM GN755, POM GT525, POM H***50, POM HC750

(4) POM product shrinkage rate is large, easy to shrink or deformation. POM has high specific heat and die temperature (80-100 C). It is very hot when the product is demoulded. It is necessary to prevent scalding fingers., POM LA541, POM LA543, POM LD755, POM LM511, POM LS701, POM LT200, POM LT350, POM LT802.

(5) POM should be processed under the condition of "medium pressure, medium speed, low material temperature and high mould temperature". Control mould temperature, POM LT804, POM LV450, POM MG210 and POM MT754 are needed in the forming of precision products.

(6) High mechanical strength and rigidity

(7) Maximum fatigue strength

(8) Good environmental resistance and resistance to organic solvents

(9) Strong repetitive impact resistance, good electrical properties, good recovery, self-lubrication, good wear resistance, excellent dimensional stability., POM SH210, POM SH310, POM SH410, POM SH510, POM SH710, POM TFC64, POM TFC64N, POM TFC64N, POM TFC64N
