Stress Cracking
Plastics which remain in contact with chemicals for long time periods undergo stress. Futher physical stress may cause stress cracking.
Molding Time
A period of time spent for molding. It sometimes refers to the time spent to heat and harden thermosetting plastics.
Molding Material
A material used for molding There are two kinds of resin materials for injection molding: thermoplastics and thermosetting plastics.
Molding Cycle
A series of steps necessary to complete one molding, or the period of time spent for the molding. The cycle in which the time for injection,…
Molding Temperature
The temperature necessary to melt a molding material.
Molding Pressure
The pressure necessary to mold molten plastics. Molding pressure is calculated by dividing the load onto molten plastics by the project area of the part (the…
Sprue
A channel through which molten plastics is transferred from the nozzle to the runner. It sometimes refers to the solidified plastics at the location.
