Technical description of Plastic injection molding machine
Model of the machine: BT 780 V-I (screw Ø 100)
Manufacturer: Guangzhou Borch Machinery Co., LTD (China)
Content:
1. Automatic loader SAL 800G 2, 2 h.p.
2. Drying machine with storage bunker SHD 150 + MST: 300
3. Mixer SHINI SVM 150
4. Chiller AEC Cooling capacity 72 kWt
5. Crate box mold
Production date: 2008
Period of exploitation: 8500 hours
Closing unit:
- fast-moving slide plate starts movement powered by closure cylinder
- fast-moving slide plate closes itself under high pressure when it approaches to the crate box mold
- there occurs the process of injection and cooling
- the crate box mold opens slowly
- the crate box mold opens fast to the required position
Injection and closing during runtime are made in turn. All actions are provided by hydraulic system under computer control.
