Plastic moulding punching machine - with adjustable core and die plate parts for dimensional discrepancy compensation

摘要

A punching machine for three-dimensional injection mouldings of plastic such as bumpers for motor vehicles, includes a split core and a split die plate can be adjusted relative to the other parts of core and die plate. This allows for a compensation in discrepancies caused by shrinkage. Holes can now be punched in bumpers or radiator cowls for motor cars in precisely defined locations.
