Sheet metal processing is now involved in a wide range of fields, such as home furniture, machinery and equipment, transportation and other sheet metal workpieces are becoming more and more common. Considering the different uses and requirements of the goods, the processing procedures are also different. Spraying is generally a process that covers all sheet metal plus product workpieces, and the following are some of the difficulties that often occur in the case of spraying.


Difficulty 1: Refurbishing a part of the peripheral surface paint bulge into a ring shape. This is mainly because the substrate is not thoroughly hard bottomed, causing absorption of the top coat. The sandpaper was too coarse, and the topcoat used an unsuitable paint thinner. The part repaired with putty or eye filler ash was not properly lapped or closed before spraying the topcoat.


Prevention method: sand the repaired part until the metal material layer is exposed; environmental protection sheet metal processing in the edge of the exposed paint layer using paint thinner to carry out organic solvent experiment, if the paint material becomes soft, this paint film must be sealed. Putty and eye filling ash can only be used on the exposed alloy and cannot be covered on the original paint surface. Use sandpaper suitable for your own sanding; make it clear that all preparation materials have long been thoroughly dry.
