The moulding and curing process is fully controlled and monitored by means of PLC Siemens S 7 (or as per the customer's request)
The loading device allows relocation of semiproduct to the press and subsequent relocation of final tyres off the press.
All the above data can be modified as per the customer's request.
Description of curing press VL 90”
The VL 90" curing press is a single-dome hydraulic mechanical press with the B.O.M. membrane system for moulding and curing of diagonal and radial tyres for building and special machines and tractors. It is the continuator of the successful line of hydraulic-mechanic presses VL 100“ utilising an original design that combines the traditional mechanical BOM system along with a hydraulic design of movements and central mechanism (the membrane controlling cylinders).
Lifting and tilting of the upper parts of the steam dome is solved by means of pulls and eccentric wheels, the drive comprises a pair of electric motors with direct drive via a pinion. Tilting is performed by a pair of hydraulic cylinders. Both movements are speed adjustable. The press is equipped with a thermal insulation of the steam dome.
The entire activity is controlled from a control cabinet, including the loading / withdrawing device. As standard, we provide our presses with Siemens or Alain Bradley control system.
In automatic mode, the press operates from gripping the semiproduct in front of the press, up to lowering of a final tyre to the cooling place next to the press.
Presses are typically delivered in a version with a steam dome or with heater plates. In both cases, the pressure vessel certificate is a matter of course..
