Message from THE GM

Hello, and welcome to PTJ – I am very excited to share what we can offer you!

For over a decade we have been designing, creating, and delivering amazing products to our customers across the globe. We have made that possible by always putting the customer first, and by always delivering a winning product.

I have always believed in delivering a total solution for prototyping where you can design, build, test, and replicate your designs – all under one roof. Combining that with my desire to be the best prototype maker in the world has helped us become what we are today – a 9,000 square-meter manufacturing operation.

It is an exciting time to be in this industry. Technology advances daily and with it, production methods and machinery. It’s incredibly satisfying to constantly reach new manufacturing and prototyping heights.

I invite you to explore our company, please view our wide range of manufacturing and prototyping services. We would love to help you create your next part, prototype, or component.

Lastly, I personally invite you to tour our factory here in Dongguan. I will personally give you a tour of our facility and answer all of your questions.
