MOLD TEMPERATURE: 305-350oF
Cavity Pressure: 1000-2000 PSI
Preheat Temperature: 150 – 180 Deg. F (Can Use Microwave Oven)
Preheating is not next is recommended to pre-Plasticize Material.
This promotes better flow and can reduce cycle time.
Close Time: 1-3 Seconds for Small Parts / 3-5 Seconds for Medium / 4-7 Seconds for Large
Cycle Time: 60 Seconds or Less for Small Parts / 60 Seconds TO 180 Seconds for Medium / 180 or More for LaRge
