About us
GUAN SHENG
At the beginning of our establishment, we were a small machining shop. We adhere to the exploration and innovation of technology,
the pursuit and control of details, and the enthusiasm and thoughtfulness of customer service. In just two years, we have won praise and support from more customers. Due to the needs of the business, we have upgraded the equipment, and the production capacity has also increased with the continuous expansion of the production line.

MESSAGE FROM CEO
Hello, welcome to Guan Sheng - I'm glad to share with you what we can do for you!
We've been designing, creating and delivering amazing products to clients around the world for over a decade. We make this possible by always putting our customers first and always offering hight quality products.
Growing up in the countryside (near to sea side) taught me the value and rewards of hard work. I took it with me when I entered the industry as a CNC operator in 2002, working my way up the ranks and educating myself every step of the way. I use this experience and background to create an environment where our team and clients feel comfortable, inspired, and proud of what we accomplish together.
I've always believed in providing a complete solution for prototyping where you can design, build, test and reproduce your designs all under one roof. Combining this with my desire to be the best prototype builder in the world has helped us become what we are today - a 2,700 sqm full manufacturing operation.
It's an exciting time to be in this industry. Technology is advancing every day, and so are production methods and machinery. Constantly reaching new manufacturing and prototyping heights is incredibly satisfying.
I invite you to pay a visit to our company. You can see us with wide range of manufacturing and prototyping services. We'd love to help you create your next part, prototype or component.
Sincerely,
OUR TEAM

Nathan Cheng
Founder, CEO
For almost 20 years I’ve been involved in design and CNC production. Helping clients create parts, prototypes, and countless other projects has been an exciting experience and it’s why I love my job. Our team is an incredible collection of talent, skill, and personalities I have the pleasure of serving. I absolutely love sports – playing or watching. In my leftover time, it’s about strong mind and strong body – I am always studying new tech and exercising in the gym.
