Traditional definition of plating equipment plating processing process generally coloured plate bottom plating, on the partition plating, laser laser plating, secondary plating, retreat partition varnish and spray protective film; and plastic plating refers to the use of chemical nickel plating and electroplating in the way of plastic surface coating metal material plating processing technology.
Plastic plating is now common in the processing of new materials and new technologies and new technology fusion of technical, it broadens the traditional definition of the scope of application of plating, plating equipment for the development trend in the field of creating a new upgrading of the industry, called the traditional definition of plating processing process, a ‘beautiful big back’, with a wide range of prospects for the industry.
Plastic products through the plating of metal materials layer, preserving the plastic parts of lightweight, high quality and low price, high production and processing efficiency; and has a metal material appearance, electrical conductivity, heat transfer and aging characteristics, now plastic plating has been widely used in electronic devices, optical equipment, CNC lathe keys and light industrial products and other aspects.
Plastic plating technology is still relatively cumbersome production process and processing technology limitations, there are, for example, poor plating solution credibility, the actual operation is difficult, the plating quality is not stable, very easy to appear black spots and other defects. However, a new type of immediate catalytic reaction or immediate plating of plastics has been developed and designed to shorten the manufacturing process and improve the reliability of the plating layer.
In improving the compressive strength of plastic parts, relying on the addition of tiny particles to shorten the raw material chemical fibres or particles doping, resulting in high toughness polymer materials, in addition to grasp the plastic plating parts passivation treatment before the treatment process, can be received satisfactory practical results.
Should take into account the plastic is a conductive medium, can not immediately just start plating, essential to use the stacking of conductive ceramic film will be transformed into a conductive negative way.
Therefore, the plastic plating equipment on the type of plastic, product design, manufacturing and processing technology are clearly put forward high requirements. Nowadays, the general plating plastic types are ABS, polypropylene and polyester, etc., in particular, ABS plastic is widely used, the actual effect of plating is.
Considering that the inappropriate product modelling design will cause the commodity product workpiece part of the ground stress and reduce the plating interface tension, the requirement of plating plastic should prevent a lot of plane, and need to round off all the edges and corners, in addition to not suitable for too thin, thin and thick do not have to have a sudden change to ensure that the quality of the plating.
Because the plastic parts after plating surface shortcomings will become more and more eye-catching, thus the surface smoothness of the mould shell requirements are very high, metal drawing, spinning, trimming, sandblasting process and other decorative design of the actual effect will have to be done in the mould shell on the go out, commodity products workpiece injection processing generally do not use the film releasing agent, in order to better be able to better out of the mould is convenient, the mould shell should be made according to the mould orientation production to a certain degree of gradient.
