baby leg mould and PVC moulding
recognised method of producing hollow plastic articles is by rotational
moulding.This process however, especially when processing PVC, requires
moulds that are corrosion resistant, of high thermal conductivity,
capable of accommodating sharp fluctuations of temperature, with
relatively thin wall sections but remain mechanically strong enough
to give accurate reproduction of fine detail. Electroformed Nickel/Copper
moulds meet this criteria.
can be supplied individually mounted,fitted with auxiliary attachments,or
as a 'gang' of several moulds mounted on to a metal frame with a
common closure system.
service includes provision of masters which for smaller items would
normally be in wax, but larger components requiring extra stability
are better suited by using acrylic or polyester.
R.I.M and self skinning foam processes are well served by electroforming,especially
where leather grain or other fine detail is required. These shells
are normally supplied as 3-5mm thick nickel. Backing of shells depends
on the application, but can
include filled resin,aluminium casting,or a simple frame to meet
