Band iron bending and forming is made, and reinforcing frame will bag insulating cement, the same cathode hanging fixture of baking process；
Integral manufacturing：Two is each above and below negative electrode and anode has reserved mounting hole, and connecting plate, which is made, with band iron is assembled to cathode hanging fixture
On, and cathode hanging fixture wraps insulating cement and then is bolted connection with anode together.
The present invention is advantageous in that：The present invention overcomes the inadequate natural endowment of plating chromic electrolyte dispersibility difference, will be usual
Separate type anode and cathode design be changed to combine Contiuum type tool structure, anode is made like shape dress and put, by making conformal anode
So that the electric force lines distribution between negative and positive level is uniform, so as to obtain the qualified products of each several part thickness of coating uniformity.In the moon
On the hanger of pole, by Element Design into horizontal clamping, it is easy to the plating solution of inside parts smoothly to flow into and out, avoids the occurrence of life of choking with resentment
The problem of rust.Implement to electroplate using conformal anode frock, thickness of coating deviation range can be controlled within 10um, electroplated per groove
The qualification rate of product reaches more than 95%.Frock hanging tool structure simple and compact, clamping is convenient, accurate positioning, high efficient and reliable, safeguards
It is convenient, fully meet electroplating technology and the production requirement of product.
