Professionalism & Efficiency Drive Real Cost Savings!
Direct-from-factory custom precision parts, mold inserts, and components tailored for plastic, optical, and die-casting molds 。
WHO WE ARE
PrecisionChina is a premier, ISO 9001 certified manufacturer specializing in close-tolerance precision machined components and high-end mold inserts. Backed by over 20 years of technical expertise, our 2,500 square-meter facility delivers full-service solutions, including professional DFM engineering evaluation, mold design, advanced CNC programming, and precise component fabrication. We serve as a trusted manufacturing partner for global engineering teams demanding flawless quality and geometric accuracy.
WHY CHOOSE US
We eliminate the middleman to offer premium quality with a 30% direct-factory cost advantage. While China hosts over half a million trading companies that markup factory quotes, our independent facility controls the entire manufacturing process in-house. By bypassing these brokers, we return that 30% profit baseline directly to our customers, ensuring you receive world-class machining capabilities without the unnecessary trading overhead.
OUR MAIN SERVICE
Our advanced production lines feature high-speed CNC milling, precision turning, 5-axis machining, and micro-drilling. We specialize in complex electrical discharge machining (Wire EDM), internal/cylindrical grinding, and custom mold accessories tailored for optical, injection, and die-casting molds. Additionally, we provide comprehensive in-house industrial surface treatments—including anodizing, passivation, and powder coating—and professional design and fabrication of inspection fixtures and jigs.
OUR ADVANTAGE
Efficiency and accuracy drive our operations. Upon receiving your original STEP/IGES drawings or physical samples, our senior technical specialists will perform an immediate engineering evaluation, guaranteeing professional feedback and transparent quotes within 24 hours. Every custom component undergoes rigorous dimensional verification via our Zeiss Coordinate Measuring Machine (CMM), translating our zero-defect commitment into certified, data-driven reliability for your critical projects.

With over 20 years of rich manufacturing expertise, we offer fully integrated, direct-from-factory one-stop machining solutions for both domestic and global customers demanding uncompromising geometric accuracy and ultra-high part precision.
We provide full-range CNC Milling & Turning services, equipped with advanced CNC milling machines, precision CNC turning centers and automatic lathes, as well as high-performance 5-Axis CNC Machining equipment for processing complex curved surfaces and irregular structural parts that cannot be completed by conventional 3-axis machining.
Focusing on mold core accessories production, we customize high-precision Optical Mold Inserts, injection mold inserts andDie-Casting Mold Inserts, supporting full-set Precision Injection Mold Making and die-casting mold auxiliary processing, matching strict tolerance standards of optical molds, automotive molds and medical precision molds.
How We Work: From Blueprint to Delivery
We streamline your custom manufacturing journey into three simple, highly secure, and efficient phases.
Step 01: Start A Free Quote (Within 24 Hours) Send us your 3D/2D CAD drawings (STEP, IGES, DXF) or physical samples. Specify your project requirements such as resin/metal materials, surface finishes, and demand quantities. Our sales team will evaluate your data and provide a detailed, transparent quotation within 24 hours.
Step 02: DFM Engineering & Mold Design Once finalized, our senior engineering team conducts a thorough DFM (Design for Manufacturability) evaluation and mold flow analysis. Within 1 to 2 days, we review all optimization details regarding part geometry and mold construction with your team to prevent defects before any steel is cut.
Step 03: High-Precision Tooling & Mold Making We order certified tool steel/mold bases and launch the in-house machining process. Utilizing advanced production lines—including multi-axis CNC milling, precision turning, slow-feed Wire EDM, and micro-grinding—our highly skilled technicians build your core components to sub-micron tolerances.
Step 04: Mold Trial & Troubleshooting We set up the completed mold to perform functional injection molding tests. We verify the exact mechanical correctness of the molded parts and keep comprehensive tracking data in records. Typically, it takes 1 to 2 rounds of strict mold trials and meticulous micro-modifications to ensure the tool is flawless.
Step 05: Mass Production Upon your sample approval, we prepare the production-grade resins or metals and finalize quality acceptance documents. Molds are securely set up in our automated systems to scale up batch production efficiently without compromising quality consistency.
Step 06: Quality Assurance & Global Shipping Every custom component undergoes rigorous dimensional verification using our Zeiss Coordinate Measuring Machine (CMM) and digital inspection instruments. Flawless parts are custom-packed and labeled to meet global specifications, then safely shipped directly from our facility via air or sea.
OUR MISSION
Empowering Innovation with Flawless Precision Our mission is to bridge the gap between complex engineering designs and absolute production reality. By combining sub-micron multi-axis tooling technology with rigorous, data-driven Zeiss CMM inspection, we commit to delivering zero-defect component execution for high-tech industries worldwide. We are dedicated to maximizing our customers' global competitiveness by providing elite, direct-from-factory custom manufacturing solutions that continuously drive real engineering cost savings.
