Wilmington Machinery has built and installed two vertical structural foam presses for a customer looking for a machine more suitable than a horizontal press, but with all the advantages vertical presses provide.
The two new large vertical type low-pressure structural foam presses accept between one and six moulds mounted and can produce one to 20 components per cycle. Each vertical press mould is filled independently and precisely by Wilmington’s proprietary Versafil injection system.
To meet customer demands, Wilmington re-engineered the MP800 injection unit to incorporate a first-in, first-out, reciprocating screw of 30:1 L/O and an in-line accumulator arrangement. The design maintains the ability to compound both virgin and recycled resins with various fibrous and non-fibrous additives for strength and reducing the cost of the moulded component.
Direct gas injection into the extruder barrel provides large part thin-wall structural foam moulding. The machine is also capable of non-foamed moulding of medium-sized parts.
The MP800 model retains its capability of both cold and hot runner moulds using either short shot (foam) or pack/hold moulding techniques.
A second complete Wilmington Machinery plastic pallet moulding system has also recently been delivered to a European customer.
The US-based company is inviting attendees to its stand (Hall 13, booth B91-19) at this year’s K trade fair in Düsseldorf, Germany.
