Line Upgrade and Retrofit

Manual-to-Automatic Line Conversion

Manual-to-Automatic Line Conversion transforms existing manual electroplating, anodizing, and surface treatment lines into automated production systems, reducing dependence on manual handling and improving process consistency. Conversion solutions include automatic gantry hoists, flybar handling systems, conveyor integration, PLC and HMI controls, and automated process recipe management. Each conversion is engineered around the existing tank layout, available factory space, production capacity, and operational requirements. By automating workpiece transfer, immersion timing, and production sequences, manufacturers can improve productivity, reduce human errors, enhance workplace safety, and achieve more consistent surface treatment quality while retaining suitable existing equipment.

System overview

Engineered around your production requirement

Converting a manual surface treatment line into an automated system requires careful evaluation of the existing production arrangement, equipment condition, and process requirements. The objective is to establish a more structured and repeatable production workflow while making effective use of existing infrastructure.

The conversion process begins with an assessment of tank spacing, structural supports, loading capacity, available overhead clearance, and access for maintenance. Particular attention is given to whether existing tanks and supporting structures can accommodate automatic transfer equipment or require modification.

Production sequences are then reviewed to determine suitable hoist configurations, transfer routes, processing priorities, and cycle times. Depending on the production layout, the conversion may involve installing overhead gantry structures, extending tank support frames, rearranging loading stations, or introducing intermediate transfer positions.

Automated operation allows different products to follow predefined treatment sequences, with controlled immersion times, lifting movements, and transfer priorities. For facilities processing multiple product types, flexible recipe configurations help accommodate variations in treatment requirements without extensive mechanical adjustments.

Implementation can be carried out in planned stages, including mechanical modifications, electrical installation, control system integration, testing, and production validation. This approach helps reduce operational disruption while providing a practical pathway from labor-intensive production toward a more standardized, traceable, and scalable manufacturing process.
