Basic knowledge of POM POM

POM: English name POM, is also more difficult to bond material, bonding area 10*30mm
1, I use the Dole 3401 (or 401) to directly bond the POM, and after 24 hours, I will open it with a light touch!
2, I used Dai Le 3401 (or 401) plus low agent for bonding, and after 24 hours, I also opened it!
3, I first polish the POM (roughly you can use a rake or a saw blade), but don't use too much force, feel the surface is rough, and then use the Dlay 3401 (or 401) to stick directly. It's difficult to open it with your hands for 24 hours.

Typical application of POM POM:
POM has a very low friction coefficient and good geometric stability and is particularly suitable for making gears and bearings. Because of its high temperature resistance, it is also used in pipeline devices (pipe valves, pump housings), lawn equipment, etc.
Injection Molding Process Conditions:
Drying: If the material is stored in a dry environment, it usually does not require drying.
Melting temperature: homopolymer material is 190~230°C; copolymer material is 190~210°C.
Mold temperature: 80~105°C. In order to reduce the shrinkage after molding, a higher mold temperature may be selected.
Injection pressure: 700~1200bar
Injection speed: Medium or high injection speed.
Runners and gates: Any type of gate can be used. If tunnel-shaped gates are used, it is best to use shorter types. Hot-nozzle runners are recommended for homopolymer materials. For the copolymer material, either an internal hot runner or an external hot runner can be used.

Chemical and physical properties of POM POM:
POM is a tough, elastic material that has excellent creep resistance, geometric stability, and impact resistance even at low temperatures. POM has both homopolymer and copolymer materials. Homopolymer materials have good ductility and fatigue strength but are not easy to process. Copolymer materials have good thermal stability, chemical stability, and ease of processing. Both homopolymer and copolymer materials are crystalline materials and do not absorb moisture easily. The high degree of crystallinity of the POM leads to a very high shrinkage, which can be as high as 2% to 3.5%. There are different shrinkage rates for various different reinforced materials. google_protectAndRun("ads_core.google_render_ad", google_handleError, google_render_ad);
