Sincere Tech is mold and tooling manufacturer in China, we produces a large number of CNC machined Engineering Prototypes for all levels of functional product evaluation. CNC Machining is one of our core competency, and we have continuously invested in new CNC machines, hardware, software, systems and training to maintain world-class capabilities, focused on speed and accuracy.

We machine Engineering Prototypes from many plastics, metals ( stainless steel & aluminum) and composite materials. Customer requests typically range from one to 100 machining parts, and may focus on a single, key component, or include all of the mechanical parts in a product. Customers use our CNC machined parts for everything from thermal and RF testing to evaluating acoustical and environmental performance.

Effective use of Engineering Prototypes helps product design teams refine and stabilize the functional details of their parts and assemblies, reducing the chance that later design changes will interrupt and add cost to the tooling cycle.

Our CNC machining capabilities include vertical and horizontal milling centers, wire and die-sinking EDM, and a full complement of supporting processes including custom milling and turning, grinding, tumbling, heat treating, media blasting, and welding, and post manufacturing include powder coating, anodizing, printing, chrome, manual product assembly service, etc.

Our experience with milling plastics, both neat (unfilled) and as composites is extensive. In some cases, when specialty materials are not available as machining material, we have the capability of molding small and medium-sized billets from injection molding resins, and using these as machining material. We have also developed a custom modular fixturing system that makes these molded stock materials convenient to load and unload with automatic positioning.

Achieving Speed and Quality

We use a combination of software tools to ensure high as-machined dimensional accuracy, good surface quality, and efficient high speed machining. The majority of our part machining is done using UG software. We maintain an extensive software definitions library of cutting tools and substrate materials, which our programmers access to ensure we machine with optimal conditions.

We have also implemented process verification software to identify risk areas in CNC machining, and ensure a high success rate. This software simulates the entire machine environment, including table, spindle, workholding, tool checking, and cutting tool library. Most recently, we have also implemented a cutting path optimizer, which maintains constant material removal rates, making sure there is a constant loading on the cutting tool. This provides us with a significant time savings
