don't just look at the price. There are many types of prototype models to be considered from the aspects of quality, cycle and service, which can be roughly divided into ten categories. Different types of prototype forming are selected according to different requirements of parts materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life, economy, etc. The prototype with high precision requirements needs to be processed with high precision CNC machine tools, and the prototype materials and forming processes have strict requirements. CAD/CAE/CAM prototype technology is also required to design and analyze. Some parts have special requirements when forming, and the prototype also needs advanced processes such as hot runner, gas auxiliary molding and nitrogen cylinder. Manufacturers should have CNC, EDM, wire cutting machine tools and CNC imitation milling equipment, high-precision grinding machines, high-precision three-coordinate measuring instruments, computer design and related software. General large stamping prototype (Such as car cover prototype) It is necessary to consider whether the machine tool has a blank holder mechanism, even side lubricants, multi-station upgrades, etc. In addition to stamping tonnage, the punching, feeding device, machine tool and prototype protection device are also considered. The manufacturing methods and processes of the above prototypes are not available and mastered by every enterprise. When choosing a prototype manufacturer, we must understand its processing ability, not only to look at hardware equipment, but also to combine management level, processing experience and technical strength. For the same set of prototypes, there is sometimes a big gap between different manufacturers. You should not pay more than the cost of the prototype value, but also less than the cost of the prototype. Shenzhen prototype manufacturers, like you, want to make reasonable profits in the business. Ordering a prototype with a much lower offer will be the beginning of trouble. Users must start from their own requirements, comprehensive measurement. Avoid multi-head cooperation, prototype production and product processing as much as possible (Qualified test pieces), May not produce a batch of qualified products. This is mainly related to the selection and forming process of machining machine tools (Forming temperature, forming time, etc)And the technical quality of the operator. With a good prototype, there is also a good forming process. It is best to cooperate in one stop and try to avoid multi-head cooperation.


The manufacture marketing game of 3d printing principle is changing with each innovation, and businesses of all products need to be ready to pounce.
