Sonnax develops every new product with you in mind. Over the past year, we’ve released three vacuum test plates – and we want to hear from you about which applications to cover next.
Which plates would help your shop the most?
Why did we do this?
Much like we update our cell phones and computers, Sonnax must periodically update its website to keep up with the latest technology. Over the past year, our web team has been hard at work rebuilding the Sonnax website from the ground up to make it faster and easier to use than ever before.
What are the biggest changes?
Will my bookmarks/links still work?
Links to part pages, product line landing pages and the homepage are still the same. Unit pages and tech resource links, however, have changed due to the updated navigation structure.
I used to place orders through your website...what should I do now?
Contact your Sonnax sales representative.
Do I need a login/Will my old login still work?
No, you do not need a login to access any data on the Sonnax website anymore.
How do I (or my customers) make a suggestion, offer a comment or ask a question about the website redesign?
Contact us! We welcome all questions and feedback.
