We should try our best to avoid making mistakes in the processing of handboard models, but in our customized processing industry, it is impossible to make no mistakes, so how should we remedy the mistakes? Generally, remedial materials can be used to fill over cut or wrong cut places. The commonly used remedial material in the hand board industry is atomic ash or 502 glue mixed prickly heat powder.
Atomic ash is a colloidal viscous substance, which needs to be combined with a drying agent to solidify. Imported atomic ash is expensive, such as bentex autodody filler in Germany, with a price of more than 100 / 250g; Domestic atomic ash is cheaper, with a price of more than 50 / 850 G.
502 glue mixed with prickly heat powder: take an appropriate amount of prickly heat powder and add 502 glue to make it into a thin paste. Fill the adjusted material into the over cut place and process it again after it is dry.
The premise of remedy is: the workpiece is non transparent, and the transparent workpiece is not allowed to have bonding traces. Generally, plastic parts are remedied. Non transparent parts include ABS, POM and PA. Transparent parts: PMMA, PC.
In particular, PMMA is also commonly known as plexiglass. Due to the particularity of material properties, it is very brittle and easy to crack, and there can be no bonding traces. Therefore, special attention should be paid in the processing process. Once the cutting is too fast, the whole material may break, and the whole hand board will be scrapped. Therefore, PMMA hand board samples are also more expensive than other hand boards.
