| Back Pressure: LowInjection Pressure: HighThe material is supplied dry and ready to mould in sealed, moisture proof sacks. No drying is necessary unless the material has been exposed to air for longer than three hours. The appearance of splash marks on the surface of mouldings indicates excessive moisture is present.Should drying become necessary two hours at 80°C in a dehumidifying dryer is recommended. Alternatively material may be dried for up to six hours in a hopper drier or an air circulating oven at a temperature not exceeding 80°C. |
| 备注 | |
|---|---|
| 1 . | Mould shrinkage is significantly influenced by many factors including wall thickness, gating, component shape and moulding conditions.The range values stated were determined from specimen bar mouldings of 1.5mm to 4mm wall thickness. They are provided as a guide for comparison purposes only and no guarantee should be inferred from their inclusion. (Specimens measured in the dry state, 24 hours after moulding). |
| 2 . | At conventional deflection |
