For injection speed symbol V, while pressing injection P and position displacement pressure and speed Pos. V1 = 25, V2 = 40, V3 = 30, P1 = 40, P2 = 60, P3 = 35. For posts set from Pos1 to Pos3 with the Product forecast so 90%, and 10% using holding.

Then the machine on the road manually.old close —-> high press —-> Inj. unit forward —> inject —–> Charging —-> Cooling —-> open —-> Eject.

When we have injected manually we are setting up the finished product 60 & sd 80% we run semi-automatic until the product becomes 80% sd 90%, we hold the holding speed, Holding press and Holding time until the product becomes 100%, in accordance with the quality of the product which we expect.
