What they will do for you
Magnetic Platens allow practical and safe rapid tool change in the injection moulding process. This system is perfectly designed to meet the demands of lean manufacturing.
The 'Quad-Press' system is manufactured with square poles of alternating polarity, in a chessboard configuration, with an even distribution of magnetic flux concentrated exclusively in the mould clamping area.
A short electrical pulse activates the system, securing the mould by the strength of permanent magnets for unlimited time, without consuming electrical energy. Only by another electrical pulse is it possible to demagnetise the system and release the mould.
Each square pole of the 'Quad-Press' system is an independent magnet. The total holding force available is directly proportional to the number of magnetic poles engaged with the surface of the mould.
Features
- Solid block construction allows reduced thickness of the magnetic platens
- Proximity sensor located in neutral area of platen detects presence of mould to enable activation of magnetic clamping
- Equal holding force across surface of mould
- Moulds of any shape or size are easily clamped without any modification to the mould base plates
- Platens can be easily and quickly installed to any machine by utilising existing hole patterns
- Electrical interlock and isolating key switch ensure safe operation
What are the advantages
- Significant reduction in mould change and set up times
- Reduction of machine down time
- Higher productivity and improved manufacturing flexibility
- Easy access to electrical, hydraulic and air connections due to the absence of mould clamps
Customers View
"After the initial investment cost there are no hidden extras, no need to purchase nuts and bolts for fixing tools to platens. There is a safer installation of tooling because there is no longer the need for the Setter to reach into the platen area to tighten the bolts. The mould change is performed standing outside the machine and away from the mould during its handling phase."
