What problems need to pay attention to when making prototype models

The production of prototypes should not only focus on product design, but also ignore prototype manufacturing, when some users develop products or trial production of new products, they often focus only on product development and development at the beginning, ignoring communication with prototype production units.

nowadays, there are more and more types of prototype models, which can be roughly divided into more than 10 types, we can choose different types of prototype models according to different functions and uses, for example, different types of prototype molding products can be selected according to different requirements such as parts materials, physical and chemical properties, mechanical strength, dimensional accuracy, surface finish, service life and economy.

1. Vehicles, motorcycles, toy cars, and other vehicles and prototypes of various fine components.

2. Telephone, fax machine, mobile phone, walkie-talkie, intercom doorbell and other communication products prototype. .

3. Prototypes of household appliances such as TV sets, video monitors, air conditioners, vacuum cleaners, humidifiers, etc. .

4. All kinds of aluminum alloy metal prototype manufacturing, batch aluminum alloy and plastic injection molding products.

5. Prototypes of various machine components, B- ultrasonic machines, electronic instruments, and medical devices.

6. All kinds of plaster, putty, wax carving, mechanical action tooth box, SLA rapid molding.

There are a lot of things to pay attention to in the prototyping process, at present, the Shenzhen tuowei prototype model specifically explains the problems that need attention in making the prototype model:

1. the prototype of conventional products is generally made of ABS material, which is easy to process and beautiful after prototype processing.

2. Prototype of high temperature resistant products, optional materials (1)Epoxy resin; (2)Electric wood; (3)Black PC; (4)PA (Nylon). The prototype of these four materials can not be bonded except for black PC, and the other three can not be bonded and need to be processed as a whole.

3. A product prototype for wear resistance, optionally POM or PA. Neither of these two materials can be bonded and need to be processed as a whole.

4. Prototype of high toughness product with PA or PP optional. Neither of these two materials can be bonded and need to be processed as a whole.

5. The prototype of transparent product, which can be used (Acrylic)Transparent ABS, transparent PC and other materials. The prototype made of these materials is polished and transparent to achieve the same effect as the real product.

6. Surface treatment of prototype models is generally divided into surface effects such as fuel injection, electroplating, Frosted, silk screen printing and pad printing. The prototype fuel injection is divided into smooth surface, dumb surface, sand surface, transparent color, translucent color, fluorescent color, rubber oil and other effects.

prototypes with high general accuracy requirements all require high-precision CNC machine tools to be processed, and there will be strict requirements for the materials, molding and process requirements of the prototype. In addition, CAD/CAE/CAM prototyping technology needs to be used for design and analysis. In the process, some parts will also have some special requirements due to prototype molding, this will require the prototype to be processed using advanced processes such as hot runner, gas-assisted molding, and nitrogen cylinders.
