Intensification Ratio (Ri)
By John Bozzelli In all hydraulic injection units, hydraulic power is converted, multiplied, into plastic pressure. The law of physics involved is F = P x A. That is force (F) is equal to pressure … [Read More...]

Backpressure Setting on an Injection Molding Machine
By John Bozzelli I do recommend you use 1,000-psi PLASTIC pressure for backpressure unless there is a reason not to. So on electrics it should be 1,000-psi set point. On hydraulic machines divide … [Read More...]
