particular hydro-pneumatic press was designed in-house for a refrigeration
company, to manufacture cabinet doors. The press can accept
a number of fixtures to produce a wide variety of doors.
The fixture is clamped between the platens and then the
door casing is injected with polyurethane foam. The press resists the
reaction pressure of the polyurethane, ensuring the door remains perfectly flat.
Six pneumatically operated pins are incorporated into the
lower platen to allow the foamed doors to be raised, for removal
by fork truck.
The
press is fully guarded around three sides and a light-guard
fitted across the front entrance. A full risk assessment
and FMEA was completed during the design and manufacture
to ensure compliance with European regulations and create
a reliable machine.
The
lid is opened using two hydraulic cylinders both fitted
with counter balance valves, which will hold the lid in
position should a hose fail. In addition, when the lid is
fully open it is held in position by a lock pin.
Both
the mechanical and electrical designs were completed in-house
to the customer’s specification. The company provided
a list of preferred suppliers for major components and specific
dimensions required. Upon completion of various stages of
the design, approval was given by the customer prior to
manufacture commencing.
The
project was completed on time and to the customer’s
satisfaction. The customer has now increased the production
rate of these doors and virtually eliminated any scrap parts.
