  • Composite Mouldings were tasked to build a very large pig to be carried around (by 2 volunteers) the London Marathon. Originally we expected the pig to weigh 40kg but with CML’s technical advise and their ability to use different applications and materials they were able to get the pig’s final weight down to 25kg! We found CML a pleasure to work with and their advice was a real asset to making this challenge possible
