What is molding pressure?

- May 05, 2018 -

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 plastic parts. The mold pressure determines with what force the melted resin is forced through the machine and injected into the awaiting mold.The amount of molding pressure should be enough to fill the mold completely, preventing what are known as short shots, or plastic parts that are not formed all the way.
