Cap Compression Moulding Machine
1.Obvious advantage of Compression molding --Simple system:
1)Less heating and cooling energy:
In injection molding,heating temperature should be more than 200℃.Without hot runner,cap compression molding requires lower plasticizing temperature < 180℃ in extrusion. Meanwhile, cooling consumption is also saved.
2)Less material waste in color changeover:
Each bottle cap factory need to produce cap with various colors to satisfy different customers’ demands. Therefore, we have to face the matter and cost in plastic cap moulding color changeover.
| Item | Cap injection molding technology with hot runner | Cap compression molding technology |
| Average color changeover time | 60min | 10min |
| Average color resin consumption | 50kg | 5kg |
| Manpower | 2 | 1 |
