Demo 31st March

Tue, 16 Mar 2010 16:12:41 +0000

CMPreform is holding a demonstration of its technologies in Ridderkerk, the Netherlands. We will be showing the possibilities of preforming of glassfibre and carbonfibre. Further we will be showing electrically heated moulds. These moulds show steep heating and cooling characteristics which makes high volume injection moulding processes a reality. To top this of this we will be showing a reusable vacuum bag that is made entirely in the shape of the mould thus giving an optimal fit. The bag is manufactured using a water based plastic that is sprayed onto the mould where it cures. It can than be removed and used in production.
Please find the programme here.

Carbon-fibre preforms

Thu, 14 Jan 2010 14:17:01 +0000

CMPreform is proud to announce that it can offer the technology to make preforms out of carbon-fibre fabrics. Easy and affordable. To make a carbon-fibre preform one needs a preform mould and a suitable binder. We can offer 3 variants. A thermoplastic powder, a thermoset UV curing resin and 3 types of carbon-fibre fabric that has a thermoplastic binder woven into.

Do not hesitate to contact us for more information.

Composites Europe Trade Fair Succes

Tue, 15 Sep 2009 13:28:27 +0000

The Trade Fair, Composites Europe in Stuttgart, was a succes for CMPreform. Lots of parties have expressed interest in the preforming technologies. What was especially noteworthy that the ability to preform carbonfibre cloth met with serious interest. We are now developing this technique further for our clients.

Pentair chooses the CMPreform binder

Wed, 17 Jun 2009 12:39:46 +0000

Part of the preform technology is the special CMPreform developed binder. Pentair is a long time producer of preforms for its filterhousings. However the used binder is a thermoset that is environmentally unfriendly and costly. The thermoset binder in itself is not very expensive, it is more that to control emissions, there is the need to filter the outgoing air. Further, since the binder is a thermoset the filter installation needs to be cleaned weekly at considerable costs. By applying the CMPreform thermoplastic binder Pentair rids itself from the need to continually control the emissions. Cleaning costs will also decrease. The binder is a multi compound resin which will harden. Even in the air treatment system.

For Pentair changing from a resin to a fibre is relatively easy. They just change one from the other.

The existing preform process at Pentair uses a spraygun for chopped strands and resin binder. This combination is sprayed into a negative mould, which revolves around its axis. The mould sits in what in effect is an oven. After spraying the oven is closed and the resin is left to harden.

After some minutes the preform is taken out.

The proces with the thermoplastic binder is the same, save that the spraygun now sprays a mixture of fibreglass and binder.
