Classification of Shouban Since the early Shouban was restricted by various conditions, it was mainly performed in that most of its work was done by hand, making it difficult to strictly meet the dimensional requirements of the appearance and structural drawings. The function of checking the appearance or structural rationality is also greatly reduced. With the advancement of science and technology, the rapid development of CAD and CAM technology has provided better technical support for hand-board manufacturing, making the accuracy of the hand-board possible. On the other hand, with the increasingly fierce competition in the society, the speed of product development has become the main contradiction of competition, and hand-saw manufacturing can effectively improve the speed of product development. It is in this situation that the Shouban manufacturing industry has emerged as a relatively independent industry and has flourished.
The hand boards are divided according to the means of production, which can be divided into manual hand boards and numerical control hand boards:
(1) Manual Shouban: Its main workload is done by hand.
(2) CNC Shouban: Its main workload is achieved by CNC machine tools. According to the different equipment used, it can be divided into Rapid Prototyping (RP) and CNC machining.
A: RP Shouban: The Shouban is mainly produced by laser rapid prototyping technology.
B: CNC Shouban: Mainly produced by the processing center Shouban.
The RP Shouban compares with the CNC Shouban:
The advantages of the RP handboard are mainly manifested in its rapidity, but it is mainly formed by a stacking technique. Therefore, the RP handboard is generally relatively rough and has a certain requirement on the wall thickness of the product. For example, the wall thickness is too thin to be produced. The advantage of the CNC Shouban is that it can accurately reflect the information expressed on the drawings, and the surface quality of the CNC Shouban is high, especially after it finishes spraying and silkscreening, even more brilliant than the products produced after opening the mold. Therefore, the development of CNC Shouban is becoming the mainstream Shouban Shouban manufacturing industry, according to the materials used in the production, can be divided into plastic Shouban and metal Shouban:
(1) Plastic Shouban: Its raw materials are plastic, mainly the palm of some plastic products, such as televisions, monitors, telephones and so on.
(2) Metal Shouban: Its raw materials are aluminum-magnesium alloy and other metal materials, which are mainly hand plates of some high-end products. Such as laptops, advanced player, MP3 player, CD player and so on.
Necessity of making hand-pieces (1) Checking the appearance design The hand-plate is not only visible but also touchable, so it can be intuitively reflected in the form of real objects to the designer's creativity, avoiding the "draw it out to look good and do it It does not look good." Therefore, the production of Shouban is indispensable in the development of new products and the scrutiny of product appearance.
(2) Checking the structure design Because the hand board is assembleable, it can intuitively reflect whether the structure is reasonable or not, how easy it is to assemble, how easy it is to identify problems early and solve problems.
(3) Avoid the risk of directly opening the mold Because the cost of mold manufacturing is generally high, the value of the relatively large mold is hundreds of thousands or even several million. If the structure is found to be unreasonable or other problems in the process of opening the mold, the loss may be Want to know. The production of Shouban can avoid this loss and reduce the risk of mold opening.
(4) Make the product launch time greatly ahead Due to the advancement of the production of the hand board, you can use the hand board as the promotion of the product before the mold is developed, and even the pre-sales and production preparation work can occupy the market early.
Hand board
The hand board is a (set) or a few (sets) first to be used to check whether the appearance or structure is reasonable, without first opening the mold.
