Injection moulding principles that need to be followed

maintenance bolton
Working at the fore front of the plastics industry we see a lot of the positives and negatives that come with injection moulding process. One of the biggest negatives we have been noticing is that even though it is an extremely industry and these processes are used everywhere, there seems to be a huge drop in the standard of training and personal development.  Here at GM Diag, we have been carrying out maintenance Bolton and working with the injection moulding machines for years.

The benefits that come with a machinery maintenance plan

maintenance bolton
With the large machinery our engineers see and work on on a daily basis, we also see how many issues flare up with one of these machines break down unexpectedly. Not only will it cause a stop in work, it can also mean you have to spend time and money that you weren't expecting too, to get it fixed. Now we're not saying that a maintenance plan will completely stop any unexpected breakdowns, but they massively reduce the chances. Here are some of the main benefits that come with a maintenance plan...

Why book our engineers to visit you on site?

Pipe Fitting
Our Bolton engineers spend the majority of their time out on other sites working on a range of different machinery. Over the years we have realised that it makes more sense to send engineers out to jobs than bring the jobs to the engineers. Especially when it comes to machinery that weighs over a tonne! But if you're still not sure why to consider on site machinery repair here are some of the main advantages that come with it.  On Site Bolton Engineers  The one of the advantages that...

Engel clamp rebuild

We was asked to take a look at an issue with a 600t Engel injection moulding machine. After a couple of attempts to resolve an issue with the clamp by other companies, we were asked to get involved. Our engineers carried out a full strip down of the complete toggle system and that  revealed several broken toggle pins and extensive wear to all links and bushes. The customer had been quoted a 16 week lead time to repair and in excess of £70,000.00 However we were able to hav...

Improving an injection moulding machine’s cooling system

We were approached by a new customer recently, and our engineers were asked to take a look at the existing cooling systems for their 17 injection moulding machine. Once we'd examined the machine, it was obvious to us that the current system in place needs to be replaced as a matter of urgency. Their current cooling system was plagued with leaks and a massive reduction in flow rate down time was becoming an issue. We put the customer in touch with Swegon Refrigeration who were able to supply...

We fix your machines in a time scale that suits you!

Our engineers have been working on dismantling full toggle link and toggle pins from a Engel 750 (as seen in the image below.) Most of the wear was found along one toggle pin which had seized and cracked in several places. Lead time from the machine supplier to repair this was 12 weeks and GMD estimate a full rebuild within 4 weeks at a fraction of the cost.  After the removal of two tie bars, the whole of the toggle system had to be stripped out of this 750 tonne Engel. T...
