Plastic Injection Molding 101 The Basics of an Injection ...

Plastic injection molding presses are classified or rated based on tonnage, or more specifically the clamping pressure or force. Presses can run in size from less than 5 tons of clamping pressure to over 4000. The higher the press ton rating, the larger the machine. A machine rated for 68 tons can deliver 68 tons of clamping pressure.

What is the Molding Pressure?

Apr 07, 2019· Molding pressure typically refers to a measurement of force within an injection molding machine. In injection molding, plastic resins are melted and pushed into a steel or aluminum mold, fabricating small plastic parts. The mold pressure determines with what force the melted resin is forced through the machine and injected into the awaiting mold.
