WS2 aids release in big moulds.
The mould for a large
tote bin had caused problems over a long period. The company
had tried roughening the edges in an attempt to improve
release but without success. We coated the mould. Thereafter
release improved significantly. The mould core shown here
weighed in at 1.5 tonnes.
WS2 Solves release for Cosmetics Packaging (with 5p piece)
This is a
small thin walled part with 0.25mm internal webs. Parts would
occasionally stick in the cavity. The sticking got a whole
lot worst when regrind was used. Since the mould had quite
thick sprues a lot of material was not reusable. We coated
the cavity inserts of the mould. The cycle time was able to
be reduced from 8 sec to 7 seconds and sticking was
eliminated. The first shift after coating the mould the
production increased from 22k to 32k on 100% regrind. On
going improvement 18k/day. - solved with WS2 Coating.
WS2 Solves release for Deodorant Packaging
The
cavities of a major deodorant client had a rather special
moulding made from a clear PET material which kept sticking
to the mould cavity. A small modification to the gate area
plus coating with WS2 solved the problem. As a bi-product of
coating the cavity the filling time was reduced by 0.9
seconds. Also the polished cores were causing drag marks on
the finished part. These were coated.... no more drag marks.
Side-actions have been coated to help filling and surface
finish.
WS2 releases Recessed Nameplates
Moulding
were sticking in these recessed nameplate blocks. Also the
stainless steel from which they were made was picking up due
to their sliding action. Both problems solved with WS2.
Electrical Products In-house Moulder
The company sent a small mould that had always been problematic. We coated the whole mould for a total of £136.00. Three months later they reported a saving of 140 hours downtime, 0.25 tonnes of material and they were now 5 days ahead of demand!
Sealant Packaging
The company moulds sealant packaging cartridges 44mm dia x 220 long which were regularly sticking on the cores. WS2 coated cores ran without problem. The company sends mould cores & cavities for coating with WS2 on a regular basis.
Bearings Moulder
One part in Acetal stuck in the mould about once per shift, after coating the part ran for a 4 day test period without sticking once. Since then various moulds have been coated on a regular basis.
Medical Moulder, South Coast
Small finger cores 4mm x 1mm x 15mm long were sticking. These cores required high polish and then they had to be "run-in" for 24hrs before the production was usable. We coated the polished cores which proved usable immediately. We then coated unpolished (sparked) cores these also were usable without the "running-in" period. A very happy man.
Trade Moulder
Having severe difficulty moulding a castelated core. WS2 coated core "while you wait" while worked immediately on retrial.
