Hand board model, in general, hand board is one or several functional templates made first according to the product appearance drawings or structural drawings without opening the mold to check the rationality of appearance or structure. At present, handboards are also called Shouban in different places. Next let's introduce two kinds of classification methods of the lower board model.
1、 According to the manufacturing mode, the handicraft model is divided into CNC handicraft and handicraft:
1. CNC hand board: its main work is completed by CNC machine tools. According to the different equipment used, it can be divided into RP (rapid prototyping) hand board and CNC hand board.
2. Craftsmanship board: its main work is finished by craftsmanship.
3. RP board: mainly produced by laser rapid prototyping technology. DB: CNC hand board: mainly produced by the processing center.
Compared with CNC handboards, RP handboards have their own advantages:
The advantages of RP hand board mainly lie in its rapidity, but it is mainly formed by stacking skills, so RP hand board is generally relatively rough, and there are certain requirements for the product wall thickness, for example, the wall thickness is too thin to produce.
The advantage of CNC model is that it can accurately reflect the information expressed in the drawings, and the appearance quality of CNC model is high, especially after finishing the appearance spraying and silk screen printing, even more brilliant than the products produced after opening the mold. As a result, CNC handboard processing is becoming the main stream of handboard manufacturing industry.
2、 By data used
According to the materials used in manufacturing, the hand board can be divided into metal hand board, plastic hand board and silica gel hand board:
1. Metal handboards: the original materials are aluminum magnesium alloy and other metal materials, mainly handboards of some advanced products, such as laptop, advanced single player, MP3 player, CD player, etc.
2. Plastic handboards: the original materials are plastic, mainly handboards of some plastic products, such as TV sets, monitors, telephones, etc.
3. Silica gel hand board: the original material is silica gel, which mainly shows the design shape of products, such as cars, mobile phones, toys, handicrafts, daily necessities, etc.
