1. Heavy steel fabricated body of l-beam and plates construction.
2. Graded cast-iron platens of liberal thickness.
3. Uniquely designed telescopic main press cylinder. Cylinder is openable at both ends for insitu - servicing. The use of telescopic cylinder results in fast and accurate operation of the press with mould beginning to close at fast speed, low pressure. Slow mould closing at full pressure can be selected to develop desired pressure just before mould is fully closed. This not only provides safety to the mould, but also results in substantial power saving.
4. Top platen approach and return are at dual speed.
5. Variable breathing cycle at intermediate pressure before final curing pressure, is possible to degas the mouldings.
6. Top and bottom ejecting systems are provided.
7. Slow opening feature is provided to prevent mouldings from breaking due to jerks during opening.
8. Electrical and hydraulic controls are in-built with the press and integrated to provide flexibility of working.
9. Safety gate is fitted to reverse the machine, if opened during pressing period.
10.Heating points are provided for both platens, and controlled by electronic temperature controllers.
11. Transfer moulding facility can be provided, extra. Standard machine is suitable for compression moulding.
Operating cycle as under:
Operator closes safety gate by push button actuatuon -- fast approach of moving platen (top platen) -- automatic changeover to slow speed -- mould close at reduced breathing pressure -- mould breathe (one to many depending on setting) -- press full close at desired high pressure -- motor automatically off -- cure -- motor automatically on -- press slow open for set distance -- press fast return -- press slow stop at upper extremely and safety gate opens automatically -- time delay -- ejector operates (top or bottom depending on setting. Top ejection is by reoperation of the top plate for a set distance and bottom ejector is operating from below for a set stroke ) -- time delay -- ejector return ( for bottom ejector only) -- motor stops automatically -- to start fresh cycle, actuate push button.
