Vibratory Plating

Vibro-Barrel

We offers vibratory plating service to bulk process delicate work piece as alternative to barrel plating. Vibratory plating is designed to prevent entanglement, deformation, scratches and other mechanical defects on work piece. It is commonly employed in plating of pin, switch, connector and terminal. Plating finishes available including nickel, silver, palladium and gold. Vibro-Barrel – Concept A vibration generator transmits oscillation pulses to the basket through the vertical shaft. This vibration causes the parts to move slowly around the basket’s axis while gently being mixed and agitated. The parts move over rows of cathode contact that located at the bottom of the basket, while maintaining electrical contact at all times. There are plastic screens located at the bottom of the basket, which allow exchange of chemical solution. Thus, ensure constant current density and uniform plating. Vibro-Barrel – Benefits Reduces precious metal consumption  The vibratory action helps to dislodge trapped solution from the plated parts decreasing the amount of drag-out and increasing the effectiveness of the rinse cycles. Eliminates part damage  A wide variety of part sizes and types can be plated in these units. The gentle vibratory action reduces tangling and protects small delicate parts from being bent, scratched, or otherwise damaged. Minimizes drag-out  The vibratory action helps to dislodge trapped solution from the plated parts decreasing the amount of drag-out and increasing the effectiveness of the rinse cycles. Vibration improve parts lapping defects  The vibration action helps to separate the parts during the plating process to prevent overlap together. Vibro-Barrel Plating Line

Selective Plating Technology

Reusable, Easy Handling Masking Used During Plating Process.

The main use of selective plating is to focus plating on the functional area, thus bringing down plating costs. The area of a part not to be plated is masked so that it is not plated. Epson is currently providing two types of selective plating: nickel and silver. We also work closely with our customers to provide customized solutions that meet and exceed their expectations. r Selective Nickel Plating Selective nickel plating is used for high-pressure turbine support assemblies, which are plated at a minimum thickness of 500µm. Unplated areas are masked with masking tape during the plating process. Main Application/Advantages Epson has developed a new plating production line concept that reduces the time taken from days to hours, uses a smaller solution tank and delivers better quality. Please refer to the relevant pages Aerospace Industry，Nickel Plating Non-Bath Selective Plating (NBS) Non-bath selective plating (NBS) is performed using Epson's self-designed machine, which has a solution agitation system specialized for selective plating. The internal diameter of the part to be plated is used as a bath, while any non-plated areas are covered with a rubber mask. The bath level is automatically controlled and the loading jig and rubber mask are specially designed to cater to different sizes. Main Application/Advantages NBS is used for selective silver plating. Using this method allows the special anode to control the distribution of the plating thickness, from 1~50 µm. NBS also helps to conserve chemicals and energy, thus making it environmentally friendly. Please refer to the relevant pages Oil and Gas Industry，Silver Plating

Waste Water Reycling System

Plating can be used in a variety of environmental control systems related to waste water treatment, including DI systems and water recycling systems. Epson's cyanide treatment line is used to treat all cyanide, gold and alkaline waste from production, and can treat approximately 222m3 of waste daily. Epson also has a heavy metal treatment line to treat all metallic and acidic production waste, and can treat approximately 278m3 of waste daily. These systems allow users to maintain trade effluent treatment facilities in good order and allow for quality trade effluent that exceeds PUB's regulatory and environmental requirements. Epson is working to improve the current chemical coagulation to electro-coagulation method for waste water treatment in order to minimise chemical usage and waste. Another system that Epson has developed is the DI system, which has been used as the feed source for water generation. The system is able to generate three different types of DI water (RO, LP and HP) to meet production needs using Ultra Filtration and an RO system. The DI system can produce approximately 528m3 with less than 20us of quality water daily to ensure an uninterrupted quantity and quality of DI water supply. -> µS (micro Siemens) Epson's in-house water recycling system has proved to be a cost-effective and efficient way to reduce our water consumption. The system minimises chemical usage and the strain on natural resources, conforming to Seiko Epson's environmental policies and focus on water conservation. The result has been an approximately 40% recycling rate for production waste water. In addition, we also have a rainwater collection project in place. Epson is currently working to achieve zero trade effluent discharge by recycling all effluent. Operation Process
