CDP Lines
Technic’s CDP-2000 is a precision electroplating machine designed for high accuracy controlled depth precious metal plating onto loose parts, typically for pins and sockets for the electronic connector industry. Considering that only a small area at the end of the part needs to be electroplated, tremendous savings can be realized when compared with conventional plating methods.
Parts may include:
- Electrical connector pin and socket components
- Spring plunger contacts
- Terminal posts
- Or any other pin/cylindrical shaped objects manufactured as single components
Key Design Features
- Transport belts available with permanent inserts or removable cartridges depending on the volume and required flexibility.
- Dual processing lanes can be configured with the same or two different component configurations. Common chemical reservoirs supply process cells in each lane.
- Plating cells utilize precision fluid flow and level controls to produce controlled depth repeatability to within 0.5mm.
- Menu driven computer reconfigurable anodes provide plating flexibility for a variety of part types including difficult to plate parts requiring high throw into internal recesses.
- Contact roller connects cathode current to transport belt, providing noise-free low resistance electrical contact with minimal drag and no particle generation.
- Plating cells utilize a synchronized backup conveyor, which provides pressure on each part through the cells for reliable cathode electrical connection in transport belt.
Features & Benefits
- High, medium, or low volume production – Plated component throughput of 1000-20000 parts per hour
- Rapid payback with up to 70% gold savings over conventional barrel plated parts
- Unique plating cell and sparging design provides accurate and repeatable plating depth control and consistent part to part thickness uniformity
- Plating cell eliminates the ‘brown ring’ at the demarcation line between controlled depth deposit and base deposit.
Load/Unload Options
Manual or fully automatic, in-line or off-line loading and unloading of parts is available. Automation is accomplished using various technologies including:
- Vibratory bowl feeders
- Inline conveyor
- Scara robot
- Cassette-to-cassette
Gold Savings Case Study
Data presented here is the summary data from an actual case study demonstrating Gold & Dollar savings achievable when using the CDP-2000 versus barrel plating of connector sockets and pins. Plating thickness profiles used for the calculation of savings are averages of a 20 piece sample size taken from a 200 part run for both the parts.
