Brief description
Fig. 1 is the front view of embodiment core, and wherein, 1 is core, and 2 is the tip of core.
Fig. 2 is the top view of embodiment core.
Fig. 3 is the profile of embodiment core.
Fig. 4 is embodiment pictograph auxiliary cathode schematic diagram.
Specific embodiment
Below the present invention is described in further details.
The reason 1.1 pairs of part generation burrs and dross, is analyzed
The burr of part coating boundary line and the main cause of dross generation：1. the hypotelorism of negative electrode and anode；2. lead to
The current density of electricity is excessive；
Current density during 1.2 electroforming, electroforming time, relation is analyzed between thickness
Due to the requirement of spare part outside measurement, it is the place that power line is concentrated at the tip of core and the boundary line of part,
Coating sedimentation rate herein is higher than other burnishing surfaces, when burnishing surface reaches drawing requirement, the size of tip surface just beyond
The full-size of part requirements.It is thus desirable to finding equalization point between current density, electroforming time, thickness.
1.4 comprehensive analysis
When actual plating produces, placing part is equal with the distance of anode and cathode, and also cannot be to electricity in terms of cost-effective
The size specification of coating bath is readjusted；The current density controlling power line concentrated area is accomplished by disperseing these regions
Power line.
Embodiment：

The profile in the region that the wing frame of both sides, described central authorities' skeleton and wing frame are concentrated with described power line is consistent；
2.2 adjustment electro-deposition process parameters
Electroplating time needed for the transformation of frock makes part produce changes, and by a series of trial-production part, adopts
Collection data post analysis draw current density and electroforming time：
| Parameter | Current density A/dm2 | Electroforming time h |
| Before core transformation | 10-15 | 8-10 |
| After core transformation | 16-18 | 13-16 |
Reduce surplus during 2.3 quarter type
The surplus that part boundary line is reserved 8-10mm makes boundary line surplus be decreased to 1-2mm.
