About GT Prototype – 10+ Years Professional Precision CNC Machining & Rapid Prototyping Factory   Company Overview Established in Shenzhen in 2014, GT Prototype has evolved from a small prototype workshop into a comprehensive one-stop precision manufacturing enterprise focused on rapid prototyping, custom CNC machining, sheet metal fabrication and low-volume mass production. We fully align production standards with American ANSI and European DIN industrial specifications, with the entire factory running under standardized ISO 9001:2015 quality control workflows. Every prototype and custom machined component passes multi-stage dimensional inspection before delivery, eliminating dimensional tolerance deviations for automotive, medical, automation, aerospace and consumer electronics clients.     Factory & Equipment Advantages Our 30,000 square meters independent factory splits into metal machining workshop and plastic prototype workshop, separating metal cutting, plastic milling, surface finishing, assembly and inspection processes to avoid cross-contamination and improve production efficiency.   Our complete equipment lineup covers full precision processing chains: Machining equipment: 3-axis, 4-axis and 5-axis high-speed CNC machining centers for complex curved surface, deep cavity and ultra-tolerance part manufacturing; Inspection equipment: 3D coordinate measuring instruments, optical projectors, roughness testers and hardness testing machines to realize full dimensional & surface quality inspection; Auxiliary equipment: Laser engraving machines, sandblasting lines, anodizing surface treatment stations to support one-stop finished part delivery. Core Technical Team Strength We maintain a stable team of 135 full-time loyal employees, with zero high turnover of core technical staff. Our senior CNC programming and machining engineers own more than 15 years of precision processing experience, proficient in solving complex structural prototype difficulties, ultra-thin wall machining, tight tolerance (±0.005mm) processing challenges that many small factories cannot handle. Our sales & technical support team can communicate fluently in English, provide DFM (Design for Manufacturability) optimization suggestions free of charge at the drawing review stage, helping global buyers cut manufacturing costs and shorten prototype delivery cycles.   Global Business Layout   Over the past decade, our custom metal and plastic prototypes have been exported to more than 18 countries across Europe, North America, Southeast Asia and Oceania, with annual sales volume breaking 6 million US dollars. We provide stable prototype and small-batch machining support for industrial design studios, R&D labs, machinery manufacturers and medical device enterprises worldwide. GT Prototype’s core value: Precision first, stable quality, on-time delivery, transparent factory direct pricing. We are your long-term reliable China rapid prototyping & CNC machining partner.   GT Prototype cover a wide range of fields, including automotive, aviation, medical, robotics, communications and consumer electronics,etc.   Company Philosophy   Business philosophy: Focus on industry, focus on products   Service concept: sincerely respect customers, refine customer service, increase customer value, create customer satisfaction
