Product Description
Melting temperature: 240 ~ 300C; For materials with ordinary characteristics, it shall not exceed 310c, and for materials with flame retardant characteristics, it shall not exceed 270C.
Mold temperature: 30 ~ 40C for unreinforced materials, 80 ~ 90C for thin-wall or large-area components, and 90 ~ 100C for reinforced materials. Increasing the temperature will increase the crystallinity of the material. Accurate control of mold temperature is very important for PA12.
Injection pressure: up to 1000 bar (low holding pressure and high melting temperature are recommended).
Injection speed: high speed (better for materials with glass additives).
Runner and gate: for materials without additives, the runner diameter should be about 30mm due to the low viscosity of the material. For reinforced materials, a large runner diameter of 5 ~ 8mm is required. The runner shape shall be all circular. The injection port shall be as short as possible. Multiple forms of gates can be used. Do not use small gate for large plastic parts, which is to avoid excessive pressure or excessive shrinkage of plastic parts. The gate thickness should preferably be equal to the thickness of the plastic part. If a submerged gate is used, a minimum diameter of 0.8mm is recommended. Hot runner mold is very effective, but it requires accurate temperature control to prevent material leakage or solidification at the nozzle. If hot runner is used, the gate size should be smaller than that of cold runner. Typical uses water meters and other commercial equipment, cable sleeves, mechanical cams, sliding mechanisms and bearings.
