Our Journey
1998 — Industry Beginnings
Mr. Zhang Ming, founder of RpProto, entered the rapid prototyping industry and began his professional career in model and prototype manufacturing.
2002 — Company Founded
Xiamen Rapid Prototype Co., Ltd was officially established in Xiamen, China. With a team of 15 employees, the company focused on Rapid Prototyping and CNC Machining, serving factories across the Xiamen region and quickly earning strong customer recognition.
2005 — Vacuum Casting Added
RpProto expanded its rapid prototyping capabilities by launching a dedicated urethane vacuum casting department — enabling cost-effective small-batch production of plastic parts without hard tooling. The workforce grew to 50 employees, and the customer base exceeded 100 companies across various industries.
2010 — Industry Recognition
RpProto established dedicated rapid injection tooling and plastic injection molding departments, growing the team to over 100 employees and significantly expanding its low-volume manufacturing offering. Thanks to consistently high part quality and reliable service, RpProto was recognized as a Top Prototype Manufacturer in China, solidifying its reputation as an industry benchmark.
2014 — Sheet Metal Capability
To meet the growing demand for metal prototype parts and enclosures, RpProto invested in its own sheet metal fabrication facility in Xiamen. This addition significantly expanded production capacity and allowed RpProto to offer more complete integrated prototyping and low-volume manufacturing solutions — from plastic to metal, all in-house.
2022 — 3D Printing Expansion
RpProto launched a dedicated 3D printing department — adding SLA, SLS, and FDM capabilities to its existing rapid prototyping services. With total staff exceeding 200 employees, RpProto now operates one of the most complete rapid prototyping and low-volume manufacturing ecosystems in Xiamen, serving clients across automotive, medical, electronics, and consumer industries worldwide.
