A platen size of 16″ x 16″, for example, will result in 256 square inches of surface area. A platen size of 32″ x 32″ will result in 1024 square inches of surface area.
What is the unit of injection pressure?
For injection molding, the injection pressure can be between 15,000 and 20,000 psi (103–138 MPa). The average injection molding machine has 20,000 psi.
What is the injection pressure?
Injection pressure is that pressure under which the mold fills; sometimes this is called the first-stage pressure. The holding pressure is the pressure that is maintained on the melt after the mold is filled and until the gate freezes or the pressure is removed by cycle timer-control.

Can I put new vapor barrier over old?
Our best practices are that the old vapor barrier is left in place and the new one is placed over it. The old barrier even if it does not cover the entire crawl space serves to provide some additional moisture blocking and also help protect your new vapor barrier from any rocks or debris on your crawl space floor.
