Advantages of plastic hand board proofing

一是驗證外觀，產品主要就是看看外觀品質好不好，驗證設計的外觀是否完好。

First, verify the appearance. The main purpose of the product is to see whether the appearance quality is good and whether the design appearance is intact.

二是驗證結構，主要是驗證產品結構及裝配是否合理。

The second is to verify the structure, mainly to verify whether the product structure and assembly are reasonable.

三是驗證功能，實現跟真機一樣的功能以及操作合理性。

The third is the verification function, which realizes the same function as the real machine and the rationality of operation.

三是參加展會，產品還沒有上市的時候，利用這個手板來獲取訂單。

Third, when participating in the exhibition and the products are not on the market, use this hand board to obtain orders.

塑膠手板加工工藝

Plastic hand board processing technology

按工藝分：可分為CNC手板、3D打印手板、硅膠復模手板和低壓灌注手板。

According to the process, it can be divided into CNC hand board, 3D printing hand board, silica gel replica hand board and low-pressure perfusion hand board.

1、硅膠復模手板

1. Silicone replica hand board

什么是硅膠復膜？硅膠復膜可以制作很多種材料，如PC和ABS，軟膠。硅膠復膜又叫真空復模，需要3D打印或者CNC加工一個模型，之后后用原版來做好硅膠模具，然后將液體材料灌入硅膠模具，等液體材料凝固之后就形成了手板模型。

What is silicone lamination? Silicone lamination can be made of many materials, such as PC, ABS and soft glue. Silica gel lamination is also called vacuum lamination. First, a model needs 3D printing or CNC processing, and then the original version is used to make the silica gel mold, and then the liquid material is poured into the silica gel mold. After the liquid material solidifies, the hand model is formed.

2、CNC手板：就是通過CNC機器雕刻加工來生產手板的一種方式，這是手板加工的主流技術。

2. CNC hand board: it is a way to produce hand board through CNC machine engraving, which is the mainstream technology of hand board processing.

3、3D打印手板：目前使用較多的是SLA工藝技術，利用3D打印機，方便、快捷、便宜。可以快速的將復雜的手板模型制作出來。就是強度耐溫性能較差，久了也會變色。

3. 3D printing hand board: SLA process technology is widely used at present. 3D printer is convenient, fast and cheap. It can quickly make complex hand model. Even if the strength and temperature resistance are poor, it will change color for a long time.

4、低壓灌注手板

4. Low pressure perfusion hand board

什么是低壓灌注？ 低壓灌注又叫低壓反應注射成型，就是將雙組份聚氨酯材料經混合后，在常溫、低壓環(huán)境下注入快速模具內，通過材料的聚合、交聯、固化等化學和物理過程形成制品。具備效率高、生產周期短、過程簡單、成本低的優(yōu)點。主要用于產品開發(fā)階段的小批量試制，以及覆蓋件、不均與壁厚等產品的小批量生產，已廣泛應用于科技汽車等行業(yè)。

What is low pressure perfusion? Low pressure injection, also known as low-pressure reaction injection molding, is to mix two-component polyurethane materials and inject them into the rapid mold at room temperature and low pressure to form products through chemical and physical processes such as material polymerization, crosslinking and curing. It has the advantages of high efficiency, short production cycle, simple process and low cost. It is mainly used for small batch trial production in the product development stage, as well as small batch production of covering parts, uneven wall thickness and other products. It has been widely used in science and technology automobile and other industries.
