"Hand plate" belongs to the local industry terminology, the terminology is called: "sample, verification pieces, samples, such as scale models, etc. ~~~~~~!" To put it plainly, the product is manufactured in small quantities before the finalization of the verification samples.
The need for mold production of products, hand plate is in the premise of no mold, according to the appearance of the product drawings or structural drawings made one or several, used to check the appearance or structure of the rationality of the function of the prototype. Hand plate in different places also known as the first board.
The history of the board:
Early boards were limited by a variety of conditions, mainly in the majority of the work is done manually, making the boards made of a long period of time and is difficult to strictly achieve the appearance and structure of the size of the drawings
paper requirements, and therefore its check the appearance of the structure of the rationality of the function of the big discounts.
With the progress of science and technology, the rapid development of CAD and CAM technology for the manufacture of the board provides a 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 board manufacturing can effectively improve the speed of product development.
It is in this case, the hand plate manufacturing industry will stand out as a relatively independent industry and flourish.
The classification of the board:
( A) according to the means of production to break up the board in accordance with the means of production, can be divided into handmade boards and CNC boards:
(1) handmade boards: the main workload is completed by hand.
(2) CNC hand plate: 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) hand plate and machining center (CNC) hand plate.
A: RP boards: mainly produced by laser rapid prototyping technology.
B: CNC boards: mainly produced by machining centers.
RP board with CNC board compared to each other: the advantages of RP board is mainly in its rapidity, but it is mainly through the
stacking technology molding, so 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 that they can accurately reflect the information expressed in the drawings, and the surface quality of CNC boards is high, especially after the surface coating and silkscreen printing is completed, which is even more brilliant than that of the products produced after the molds are opened.
Therefore, the CNC hand plate manufacturing has become more and more the mainstream of the hand plate manufacturing industry.
Two according to the materials used
The board in accordance with the materials used in the production, can be divided into plastic boards, silicone boards, metal boards:
(1) Plastic boards: the raw materials for plastic, mainly plastic products, such as televisions, monitors, telephones and so on.
(2) Silicone hand plate: its raw material is silicone, mainly to show the shape of the product design hand plate, such as cars, cell phones, toys, handicrafts, daily necessities and so on.
(3)Metal plate: its raw material is aluminum-magnesium alloy and other metal materials, mainly for some high-grade products, such as laptop computers, high-level media player, MP3 player, CD player and so on.
The necessity of handboard production (1) check the appearance of the design
The handboard is not only visual, but also touchable, he can be very intuitive to the form of physical designers to reflect the creativity of the designers, to avoid the drawings out of the good-looking and made out of the good-looking "
the drawbacks. Therefore, the hand plate 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 installation of the degree of difficulty. Facilitate the early detection of problems, solve the problem.
(3) to avoid the risk of directly opening the mold
Because the cost of mold manufacturing is generally very high, relatively large molds worth hundreds of thousands or even millions of dollars, if in the process of opening the mold found that the structure of the irrational or other problems, its losses can be imagined.
And the hand plate production can avoid such losses, reduce the risk of opening the mold.
(4) so that the product launch time greatly in advance
Because of the advance nature of the production of handboards, you can use the handboards in the mold before the development of the product publicity, and even pre-sales, production preparations, early occupation of the market. Now the hand plate production technology has been quite mature, the production of the appearance of the product is no different from the product, many manufacturers are taking the hand plate product exhibition to obtain orders and then open the mold production. Minimize the risk.
