Simone told me about the excellent job that your team is doing there, so far we are on line with our ambitious schedule.

I think that would represent an absolute world record for the wiring operation for a 20 MN press.

Project Manager

Well done to all those involved in the design, fabrication, assembly and electrical construction of our machines. Not only have you delivered them on or before schedule, but you’ve also done it impressively. Thank you.

Thank you for the level of service that your company provides. Your company has a good attitude, your staff act very professionally, providing good advice, being punctual and not to mention work completed is of a good standard and done in good time. There is also a good level of trust and I do appreciate the effort you all put in. Please relay my thanks to everyone and especially to Paul.

On behalf of the Dairy Goat Co-op, I wish to thank those people that battled on Tuesday afternoon into Wednesday and again on ANZAC day to help DGC with scoop inserter robots that had ceased working. Often work calls for us to step out beyond the normal hours and this is a huge inconvenience in our lives. I am very appreciative and again thank you for supporting us. I think we have resolved an issue that has perhaps been there for some time.

We are fortunate that we have good support companies (with very good people) supporting our operations.

It was a pleasure to experience Don and his guys working so well in extremely taxing conditions over the weekend. Outside was disgustingly unpleasant but your guys stuck to task and we are all up and running this morning – #1 goal achieved, fantastic.

Please pass my thanks onto the team.

Thanks heaps for sorting out the cables for the new CNC. The boys were awesome.


Just wanted to acknowledge great consistent performance from Ian, Anthony & Tyrone over the last month.

Really good detail and accuracy coming through on the invoices and not to many surprises in the costs. Thanks to you all for pulling this together.

Yesterday we had a successful production start-up on the laminator Chop Knife. The Chop Knife has since been running well and all emergency stops, interlocks and guarding etc has been reviewed via a Machine hazard ID report. The project was well run with no major safety or hardware issues.

Thank you for the excellent way in which safety and work co-operation was conducted, the long hours worked and the on-time completion. We are now back to full production.
