What are stamping anticorrosive processing

Dongguan precision electronic technology co. , LTD. , founded in 2008, is the guangdong dongguan enterprise specialized in stamping parts processing, main processing lead frame, non-standard precision shrapnel, terminal stamping, precision electronic hardware components, etc. In precision stamping industry, accumulated experience; Study technology, complex hardware technology to overcome and reduce the production hardware manufacturing costs. Won the approval of all brands. In stamping parts processing to prolong the service life of the workpiece and avoid corrosion rust, usually completes the corresponding anti-corrosion treatment, general common anticorrosive processing methods are: asphalt paint coating, paint spraying the workpiece preheated before can improve the adhesion of asphalt paint, accelerate drying. Cement mortar lining with special coating, can improve the corrosion resistance of workpiece lining. Epoxy coal asphalt coating is a kind of two-component coating, the coating has good adhesion and very smooth surface. Epoxy ceramic lining due to the manufacturing process is difficult, the cost is high, so there are some limitations on use, high adhesion and bright and clean degree, is an excellent stamping anticorrosion coating. Coating or sulfate aluminate cement concrete coating, these two kinds of special cement coating are suitable for high precision stamping in corrosion protection, improve the ability of resistance to erosion. Polyurethane coating is a kind of order to adapt itself to the requirements of environmental protection and development of a new type of green, the special coating, good wear resistance and corrosion resistance. Above is the precision stamping of six kinds of methods commonly used anti-corrosion.
