LINKING SERIOUS BUYERS TO THE BEST SUPPLIERS
Serving the UK & IE plastics industry

Most plastic injection mouldings that are produced today are still compromised when compared to what they could be in terms of fully optimised product….
Scrap rates for the injection moulding industry are easy to calculate, but often painful to believe – it is simply the difference in weight between how much plastic you buy in, and the total weight of parts delivered. Typically this is as much as 10%, although when questioned about scrap rates companies reported to us the figures they wanted to talk about – such as “customer reject rates” of 4.5ppm or their “production reject rate” where we heard of 0.001%. These figures are just self-congratulatory and distorted.
