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 fix your machines in a time scale that suits you!

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.
