Clint Palmer
Remlap Tracking Pty Ltd
Remlap Tracking has been with Cresta Plastics for about 18 years. We started at the very early stages with tool design, and not knowing a thing about plastic manufacturing, Cresta Plastics arranged the manufacture of the dies for us.

Since the beginning nothing has been too much trouble, including many die modifications and changes of products along the way, just to keep life interesting.

The service the team at Cresta Plastics have provided us has always been exceptional.
E. Pasfield
R.V. Electronics
R.V Electronics Pty Ltd have been using Cresta Plastics for over 20 years. during this time, we have had a number of products produced by them, and are very happy with the quality and service that they have provided us.
Pete Miller
Cresta held my hand along the way, from design to finding a toolmaker, to production. Seriously it was incredible. Good people give great service which makes for a great product. You’d never get support like this overseas – or interstate for that matter. Having a partner like Cresta meant we could play with materials and design concepts quickly. If there was a problem with tooling we knew about it within 24 hours of delivery which sped up the process immensely.
