Improve Your Continuous Filament Winding GRP Production

Do You Want to Improve Your Continuous Filament Winding GRP Production Efficiency and Immediately Maximize Your Profits?


Did you ever calibrate the resin pumps of a dosing system for GRP pipe production? Or maybe you saw your technician going up and down, weighting the resin, changing parameters, adjusting the pumps and trying his luck?

It is always a lottery. If you want to get really precise, you have to be sure that all the calibration steps have been carried out properly, hoping that the viscosity of the resin will be the same during the entire production phase.

If your intention is to maximize your return on investment in the composites market, utilising the filament winding technology, then this article is indispensable for you.

It is important for you to know that at present, only a few continuous filament winding machines are able to produce with performances which are equal or superior to the original average objectives.

Furthermore, the most disconcerting fact is that management continues to look for new solutions to reduce the production costs, to be more competitive on the market or increase the profits. Unfortunately, this is continued search occurs because the management invested in a Continuous Filament Winding (CFW) Plant that does not allow them to be competitive enough, due to elevated scrap levels during production and the impossibility to reduce it, or the inaccurate dosing of raw material, and, even worse, due to the fact that they are producing with recipes or processes that are not optimized. With such initial conditions, is it clear that they cannot reach their cost targets?

So, how does one solve these issues in a sure and rapid way? Let me reveal a secret to you: to correct the weak points on your existing manufacturing plant is much easier than you can imagine.

If your company is trying to optimise GRP pipe production and you want to ensure that you benefit from a rapid return on investment through profit maximisation, then you cannot refrain from reading on about one of the most important steps you need to take to ensure that every dollar invested will generate profits.

As you know, in GRP pipe production the most expensive raw material is the resin.

What is the role of the resin in a pipe? It serves as the “glue” that binds the fibers together after the curing (when the resin sets). The pipe liner resin also provides the most definitive corrosion resistance to the transported fluids. It’s chemical and physical properties play a key role in the pipe design.

But we need to put the exact quantity of resin because an excess of resin means converts to waste/scrap and lower pipe specifications. Yes, you have understood correctly, if you put more resin than the exact needs for the pipe, you are spending money and producing an inferior quality pipe.

If you keep that concept in your mind all the time, I am sure that you can expect at least 2 things from your technology…
