Manufacturing Processes
Wet Lay-Up
With a suitably prepared tool, a gel coat is applied, this can be coloured, or specially adapted to have the finish sprayed post production.
The fibreglass reinforcement is then applied, resin is then applied to wet out the dry glass, and consolidated usually with a roller. This process is carried out by hand, which it is known as hand lay-up. Cost effective for parts with more complicated shapes, as the tools can be split, making it suitable for undercuts.
Closed Mold
This process involves a two part tool that will create a part that has a finish on both sides.
The material is put into the tool, which can first have a gel coat if required. The two halves of the tool are then brought together and held closed under vacuum. Resin is then introduced and left to cure. The resulting part has a good finish on both sides. The tools are more expensive to make as usually machined from aluminium, but the will last a long time and many hundreds of parts can be made from each one.
Careful thought has to go into the design of the part as undercuts, while not imposable, are much harder to incorporate in the finished part.
Vacuum Bag.
This process is similar to the closed mould system, but instead of a two part tool, the top is sealed with a flexible bag. Developed for the pre impregnated material which goes on to be oven or autoclave cured, we have developed the process to be used at ambient temperatures with many types of resin. This will produce a very well consolidated part, but due to the extra cost of the bagging material, which is replaced every cycle, this can be less cost effective than other processes.
Closed Mould or Resin Transfer Moulding
Traditionally fibreglass was just a bucket of resin with chopped strands mat, wetted out in an open mould. This is still the most cost effective method of production for low to medium volume parts, also where more complex shapes, with undercuts etc. are required to be moulded as one part. Whether you need patterns, moulds or components, if you have an idea, we can help you make it. Contact our fibreglass manufacturers today to discuss your project. Based in Suffolk, we serve clients across Cambridge, Essex and East Anglia.
