The classification of the handpiece
Early handpiece because of the limitations of various conditions, mainly in its most of the work is done manually, making the handpiece to make a long period of time and it is difficult to strictly achieve the appearance and structure of the size of the drawings, and therefore its check the appearance of the structure of the rationality of the function of the big discount.
With the progress of science and technology, the rapid development of CAD and CAM technology, for the manufacture of the board provides better technical support, making the accuracy of the board possible.
On the other hand, with the increasingly fierce social competition, the speed of product development has become the main contradiction in the competition, and the handmade board manufacturing is precisely to effectively improve the speed of product development.
It is in this case, the handmade board manufacturing industry has stood out, become a relatively independent industry and flourish.
The board according to the means of production points, can be divided into handmade board and CNC board:
(1) handmade board: the main workload is completed by hand.
(2) CNC board: its main workload is completed with CNC machine tools, and according to the different equipment used, can be divided into laser rapid prototyping (RP, Rapid Prototyping) board and machining center (CNC) board.
A: RP board: mainly with laser rapid prototyping technology to produce the board.
B: CNC: mainly produced by machining centers.
RP board with CNC board compared to each other:
RP board's advantages are mainly expressed in its rapidity, but it is mainly through the stacking technology molding, so the RP board is generally relatively rough, and the wall thickness of the product has certain requirements, such as the wall thickness is too thin will not be able to produce.
The advantages of CNC boards are reflected in its ability to accurately reflect the information expressed in the drawings, and CNC boards have a high surface quality, especially after the completion of the surface spraying and silk screen, even more than the open molds produced after the product but also glowing. Therefore, the CNC hand plate manufacturing more and more become the mainstream of the hand plate manufacturing
Hand plate in accordance with the production of the material used in points, can be divided into plastic hand plate and metal hand plate:
(1) Plastic hand plate: its raw materials for the plastic, mainly plastic products, such as televisions, monitors, telephones, etc. Hand boards.
(2) metal plate: its raw materials for the aluminum-magnesium alloy and other metal materials, mainly some high-end products of the board. For example, laptop computers, high-level video players, MP3 players, CD players and so on.
The necessity of making handboards
(1) Check the appearance of the design
Handboards are not only visual, but also touchable, he can be very intuitive in the form of physical designers to reflect the creativity, to avoid the drawings out of the good-looking and made out of the disadvantages of the good-looking. Therefore, the handboard production in the development of new products, product shape is essential to the process of speculation.
(2) Check the structural design
Because the board can be assembled, so it can visually reflect the structure of the reasonable or not, the degree of difficulty of installation. Facilitate the early detection of problems, solve the problem.
(3) to avoid the risk of directly opening the mold
As the cost of mold manufacturing is generally very high, relatively large molds worth hundreds of thousands or even millions of dollars, if the process of opening the molds to find structural irrationality or other problems, the loss can be imagined. And the hand plate production can avoid this loss, reduce the risk of opening the mold.
(4) so that the product launch time greatly in advance
Because of the handboard production of the anterior, you can use the handboard in the mold before the development of the product publicity, and even pre-sales, production preparations, and early occupation of the market.
