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?

一些手板模型的一个巨大的错误无法弥补,只能报废,如透明PMMA、PC,等等,因为透明的工件不允许有胶痕,但有些工件可以弥补损失中恢复过来,工件不透明,如ABS, POM, PA,一般为塑料部件改良。方法可以用材料填充在一般切或错切的地方，更常用的材料是502胶混合痱子粉或原子灰。取适量花椒粉，加入502胶水制成薄糊状，混合花椒粉制成502胶水。将混合均匀的物料倒入超切处，待干燥后再进行二次加工。腻子是胶黏的，需要与干燥机配合固化。

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.

结构面板主要用于验证产品的结构合理性。对面板尺寸的要求相对准确，对面板外观的要求相对较低。外国客户对这些要求尤其严格。如果从功能角度对板进行划分，可以分为外观板和结构板。非结构化的板也被称为板外观,只看到外表,不需要活动,所谓的外观外观标准只要求手类似设计的产品,或使用相同的产品,不需要它能有什么效果,这样不能用于产品销售,主要用于展览,为了做好宣传工作。

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.

木板可以活动和结构,可以看到手的功能,结构的板是内部中空,可用于电子元件,也可以用作一个成品,如汽车模型、结构的手必须有一个身体、车轮、门,等等,只要是一般的外表应该,和分布构件组装,结构相对复杂,每个位置非常精确的大小标准,否则安装可能会出现问题。

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.
