How to electro-plate plastics that does not conduct any electricity.
Process of placing conductivity on plastics that has no conductivity.
*Etching
Add hydrophilic property.
Dissolve butadiene rubber to create fine pitch to the resin surface.
Attach resin and metal using anchor effect.
*Catalyst
Add Palladium catalyst to plastic surface.
*Electroless nickel
Use palladium catalyst as a nucleus, deposit nickel layer on plastic's surface.
Deposit decorative plating film on resin surface.
*Copper plating
Good leveling effect to reduce 凹凸 on surface.
It is flexible and able to ease heat expansion pressure of resin and metal.
*Three types nickel plating
By depositing three layers of nickel plating,it is able to resist against corrosion.
*Chrome plating
It has good corrosion resistance and hard filming characteristic.
It will give surface a beautiful bluish color.
When processing resin plating, there are about 30 processes that takes 3-5 hours.(Including pre-treatment)
For each process there is always a chance for defects. But to combat those problems and keep our quality high, we have many different analyzing equipments.
Plated layer is harder than plastics, but easier to crack. Thus there is a need to design materials carefully.
*Electric current will concentrate on materials edge, causing burn deposit.
*Inner area is hard to deposit (Thinner deposit).
*Cracks may occur by concentrated heat expansion pressure.
Have at least 2-3R curve on the material's edge
