(2) Plating parts plating 1 Plating bottom layer: Because the plating layer has different bonding strength on different metals, some electroplating layers can not be deposited on steel. Therefore, for some special plating types, a layer of bottom layer is firstly plated as a transition, and the thickness is generally ( 0.00l ~ 0.01) mm.
2 Plating work plating: Working plating is the final plating layer on the surface, which is to meet the special requirements of surface mechanical properties, physical properties and chemical properties. A suitable final solution, such as a surface for wear resistance, may be selected depending on the properties of the coating, and the working coating may be nickel, nickel-tungsten alloy or the like. For corrosion-resistant surfaces, nickel, zinc, etc. can be used on the working surface. Nickel plating is the most common type of mold repair, and its plating solution is shown in Table 1.
(3) After plating, the plating is completed immediately after plating, and the residue on the edge of the plated part is removed.
1.3 Electrochemical plating features (1) Equipment features: The equipment is small in size, light in weight, and easy to carry, so that it can be operated on site or in the field.
(2) Characteristics of plating solution: Most of the plating solution is an aqueous solution of metal organic complex, which has considerable solubility in water and has good stability. Can be used over a wide range of current densities and temperatures. It has non-combustible, non-explosive, non-toxic, low corrosion, low environmental pollution, easy to operate and safe.
(3) Process characteristics The process is flexible, the deposition speed is fast, the coating type is many, and the bonding strength is high.
Application of 2 <br> <br> electrochemical plating in the plastic mold is an important application in the plastic mold surface of the mold is coated with a uniform layer of thin gold alloy, to prevent the processing of PVC or PVDC release release Corrosion of the resulting hydrochloric acid, corrosion caused by small pits will produce drag marks, crow's feet and other defects on the surface of the product, and will shorten the life of the mold. At present, electrochemical plating is generally used to plate 2.5" m thick gold alloy on the surface of the mold. This metal plating can prevent the corrosion of PVC and greatly improve the service life of the mold. Another advantage of using gold alloy electrochemical plating is that When repairing the coating, it can be repaired without removing the mold. For the polished surface, iron powder is usually used, or the surface of the mold is brushed with a soft steel brush to make the new coating fused with the surface of the mold. Together.
These materials have an adhesion to steel and chromium when forming PET, ABS, PE, PP plastic articles. Through the gold alloy plating, this can enhance the separation of this material from the cavity surface of the plastic mold. The thickness of the gold-plated alloy can meet the anti-adhesion requirements as long as it reaches about half the thickness required for forming PVC.
