Description

Monolithic plating correction fixture and its correction structure

The invention relates to a plating fixture; in particular to an innovative structural designer of a single-plate electroplating correction fixture and a correction structure thereof.

In the electroplating process, each workpiece to be electroplated usually has to be clamped to the electroplated frame structure through some electroplating fixtures.

In general, electroplating does not necessarily only target metal products, and many plastic products require electroplating. For the common electroplated plastic sheets on the market, for example, automotive rain guards and decorative sheets on bumpers are often inevitably produced after injection molding because of their own length, thickness, mold temperature and other factors. The deformation of one, if such a product is not corrected before plating, even if it is barely electroplated, it can not meet the requirements of product specification, and even enlarge the amount of deformation originally formed, the quality will be delivered to the customer, It will make the industry's own reputation greatly reduced, and over time, it will gradually lose its market competitiveness.

In addition, even if the injection molding technology is skillful, it can improve the uniformity of the shape of the workpiece after injection molding. If the plating fixture is not provided during the plating process, it may also be due to the high temperature generated during the plating process (about Celsius). Seventy degrees or so) and deformation, leading to the abandonment of the former, resulting in the waste of raw materials and labor costs, indeed have to be cautious.

Therefore, in view of the problems existing in the above-mentioned conventional technologies, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goals and directions of breakthrough.
