Injection molding machine operation instruction and good

Injection Molding Cycle = mold open/close time + injection time + melting time + cooling time, all of which need to be minimized. Generally speaking, for a 100g injection molding machine, if a 2-plate mold is applied, the mold open/close time is kept at about 2s, or appropriately longer if there are sliders. Injection time should be reduced
