Error is inevitable in the process of hand board model processing. For example, PMMA is also our common plexiglass or acrylic acid, because the material is brittle crack, and there is no glue trace, so pay special attention to in this process, once the knife is too fast, the material may break, and then it will be scrapped, so PMMA standard sample is also more expensive, What can we do to change our mistakes? How can we deal with them?

一些手板模型的一個巨大的錯誤無法彌補,只能報廢,如透明PMMA、PC,等等,因為透明的工件不允許有膠痕,但有些工件可以彌補損失中恢復過來,工件不透明,如ABS, POM, PA,一般為塑料部件改良。方法可以用材料填充在一般切或錯切的地方，更常用的材料是502膠混合痱子粉或原子灰。取適量花椒粉，加入502膠水制成薄糊狀，混合花椒粉制成502膠水。將混合均勻的物料倒入超切處，待干燥后再進行二次加工。膩子是膠黏的，需要與干燥機配合固化。

A huge mistake of some hand board models cannot be made up, so they can only be scrapped, such as Transparent PMMA, PC, etc. because transparent workpieces are not allowed to have glue marks, but some workpieces can be recovered from the loss. Workpieces are not transparent, such as ABS, POM, PA, which are generally improved by plastic parts. The most commonly used treatment material is 502 glue mixed with prickly ash or atomic ash. Take some pepper powder, add 502 glue to make a thin paste, and mix pepper powder to make 502 glue. Pour the evenly mixed material into the over cutting place, and then conduct the secondary processing after drying. The putty is sticky and needs to be solidified with the dryer.

結構面板主要用于驗證產品的結構合理性。對面板尺寸的要求相對準確，對面板外觀的要求相對較低。外國客戶對這些要求尤其嚴格。如果從功能角度對板進行劃分，可以分為外觀板和結構板。非結構化的板也被稱為板外觀,只看到外表,不需要活動,所謂的外觀外觀標準只要求手類似設計的產品,或使用相同的產品,不需要它能有什么效果,這樣不能用于產品銷售,主要用于展覽,為了做好宣傳工作。

The structural panel is mainly used to verify the structural rationality of the product. The requirements for panel size are relatively accurate, and the requirements for panel appearance are relatively low. Foreign customers are particularly strict with these requirements. If the board is divided from the functional point of view, it can be divided into appearance board and structure board. The unstructured board is also called board appearance. It only sees the appearance and does not need activities. The so-called appearance standard only requires products of similar design, or uses the same products, and does not need any effect. It cannot be used for product sales, but mainly for exhibitions, in order to do a good job in publicity.

木板可以活動和結構,可以看到手的功能,結構的板是內部中空,可用于電子元件,也可以用作一個成品,如汽車模型、結構的手必須有一個身體、車輪、門,等等,只要是一般的外表應該,和分布構件組裝,結構相對復雜,每個位置非常精確的大小標準,否則安裝可能會出現問題。

The board can move and structure, and can see the function of the hand. The board of the structure is hollow inside, which can be used for electronic components, and can also be used as a finished product. For example, the hand of the car model and structure must have a body, wheel, door, etc. as long as it is the general appearance, it should be assembled with the distribution components, the structure is relatively complex, and the size standard of each position is very accurate, Otherwise, there may be problems with the installation.
