Questions

About These Guides

Who are these guides written for?

Design engineers choosing a stack-up or a finish, and buyers deciding what to send with an enquiry. They are not marketing pieces.

Where do the capability figures come from?

From the rigid, aluminium and flexible capacity tables published by the company. Nothing in these guides invents a number.

Can you review my design against these guides?

Yes. Send the files with your enquiry and we will check them against the published capability before tooling.

How often are new guides added?

New guides are added as questions come up repeatedly. Tell us what is missing and it will go on the list.

Ask Us Something These Guides Do Not Cover

Send the question and the files. Answers come from the people who run the plant rather than from a sales script.
