1 Cycle Time Calculation for Plastic Parts Injection

2020-7-23 · 2020-7-23 · When estimating the storage time of injection molded parts, it is generally calculated between 65% and 85% of the maximum plasticizing capacity (g/s) of the injection molding machine. The injection process is usually divided into 3 stages (slow-fast-slow). Below is the estimated cycle time calculation formula: Ti=W/20~50%V + t

2018-10-29 · But you cant decide the injection capacity of the injection-molding machine simple by Wx, you have to exchange it into Wps. The formula is: Wps=Wx × 1.05 Vx. In which, Vx represents the specific gravity of certain plastic.

Injection Capacity Calculator For Injection Molding

Given the injection capacity and melt density of GPPS as well as the melt density of the material you intend to use, the calculator will work out the shot weight allowance. Use for existing molding machinery when planning to change material to determine if the shot weight allowance falls within the recommended range of 25% to 65% of injection capacity.
