Vacuum coating equipment ABS plastic plating common process

Vacuum coating equipment ABS plastic plating process can be divided into three parts, this is the pre-treatment process, chemical plating and electroplating processes. Each section contains a number of processes or procedures.

(1) vacuum coating equipment ABS plastic plating pretreatment process for pre-treatment process, including surface finishing, stress checks, degreasing and coarsening.

① surface finishing. ABS plastics before the treatment, to be a surface finishing, this is because in the plastic injection molding process there will be residual stress. Special gates and a portion corresponding to the gate, there will be the internal stress.

② the stress screening method. At room temperature injection molded ABS plastic release acetic immersed 2 ~ 3min, then carefully cleaned surface, dry.

③ degreasing. You can have a lot of choice in addition to oil business, after degreasing, first wash in hot water, then wash in water, and then in a 5% sulfuric acid neutralization, and then cleaned before entering the roughing process, so you can protection roughening solution so life is extended.

④ coarsening. ABS plastic roughening methods there are three types, namely high acid, high chromic acid and phosphoric acid type, from the point of view of environmental protection, it should adopt the high sulfate type.

(2) vacuum coating machine ABS plastic plating process plating process includes sensitization, activation, electroless copper or nickel plating

3) vacuum coating machine ABS plastic plating process is divided into thick plating, decorative and functional electroplating plating three.

① vacuum coating equipment thicker plating. Due to the chemical coating is very thin, make metalized plastic achieve the effect, the coating must have a certain thickness, so to thicken after plating plating.

② vacuum coating equipment decorative plating decorative plating can be a copper-nickel-chromium process, it can be bright copper then other finishing, such as brushing bronze after treatment, it can be bright nickel plated copper after adding in the light, then plated imitation gold.

③ vacuum coating equipment functional electroplating. Functional functional purpose actually depends mainly on the nature of the surface electroplated coating to be embodied. In fact, from a broad perspective, also a decorative function, but the function mentioned here, or physical or chemical means, or electrical properties. For example the conductive coating, reflective coatings, electromagnetic shielding coating, welding coating and the like.
