In the process of handboard model processing, mistakes are always inevitable. PMMA is also commonly known as plexiglass or acrylic, because the material performance is very brittle and easy to crack, and there is no adhesive trace. Therefore, special attention should be paid in the process of processing. Once the cutting is too fast, the whole material may break, so the whole handboard will be scrapped. Therefore, PMMA handboard samples are also better than other handboards Dear, what should we do if there is a mistake? How to deal with it?

　　Some hand models have big mistakes that can't be remedied. They can only be scrapped, such as Transparent PMMA, PC, etc., because transparent workpieces are not allowed to have adhesive traces, while some workpieces can be remedied to recover losses. Workpieces are non transparent, such as ABS, POM, PA, etc., which are generally aimed at plastic parts. Generally, the remedy can be filled in the place of over cutting or wrong cutting, and the most commonly used remedy is 502 glue mixed with prickly ash or atomic ash.

　　取適量痱子粉加入502膠水調(diào)成稀糊狀即可成為502膠水混合痱子粉，將調(diào)好的材料填入過切的地方待干后再補(bǔ)加工一下，原子灰為膠狀粘稠物，需要配合催干劑才能凝固，進(jìn)口原子灰較貴，國產(chǎn)原子灰較便宜。

　　Take a proper amount of prickly ash powder and add 502 glue to make it into a paste, then it will become 502 glue mixed prickly ash powder. Fill the prepared material in the over cut place, and then make up for processing after it is dry. The atomic ash is a glue like viscous substance, which needs to be combined with the drier to solidify. The price of imported atomic ash is more expensive, and the price of national atomic ash is cheaper.
