Thank you Hedy

I am very impressed with your progress reports.

This is good!

There will be some more new tools shortly (after Xmas), we are just finalising and testing product design

Customer from New Zealand work for batch room component.

We have been working with Hedy now for almost 7 years. During that time we have purchased somewhere between 2-8 plastic injections molds and/or stamping dies and/or rubber compression molds per year. We have been very impressed with their quality and delivery, both in the tools themselves and the fabricated parts. Most of these tools we bring into the US, but we have found it’s economical to leave some there as well. I can’t say enough good things about this company. Even our tool room manager, a 35+ year veteran of US machine shops and toolmaker himself, has given the highest compliments to Hedy and his team.

We always start with a 3d model, STP or SAT or similar format. They can quote from those, usually within 2 days, but then we follow up with a dimensioned drawing specifying tolerances and key features. From there we do a full tooling specification, developed by our tool room manager, that details fasteners, type of steel, ejectors, mold type, etc. From these documents we can get a final quote, and then once we approve and issue a purchase order we get weekly updates on the progress of the tool as well as pictures and sometimes power point presentations when there are details of the mold design that need further discussion.

I believe if you follow our model of documentation, you will not be disappointed. I would be happy to share with you some of the documents from some example projects we have completed with Hedy.
