Harinck

New advanced powderocating line, unique in Belgium

At Harinck NV in Wielsbeke, the existing powder coating line was reaching its limits. The divergent curing curves of sheet material on the one hand, and massive door handles on the other, inevitably caused bottlenecks in output. Together with Coateq, a new line was developed that addresses four core objectives: productivity, sustainability, traceability, and safety.

The installation consists of:

Routing

• Rail system with double buffer
• Strategic bypasses in all zones
• Automatic routing via barcode-controlled product parameters

Pre-treatment

• Pre-treatment based on titanium instead of chromium-VI
• Double degreasing and pickling step for improved adhesion
• Automatic control of temperature, pressure, conductivity, and pH

Drying oven

• Excellent thermal insulation
• Double automatic airlock doors
• Heat recovery from the curing oven air

Application

• Two booths (with the necessary safety procedures)
• Four spray guns (one before and one after the robot, respectively)
• HD dense-phase technology instead of the venturi principle

Gelling Oven (pre-cure)

• Runs entirely on recovered residual heat from the drying oven
• Avoids extra energy consumption
• Prevents colour contamination in the main curing oven

Water treatment

• Closed system with vacuum evaporator (PCA Water)
• Process water reuse, minimal sludge fraction
• Also connected to the older powder coating line

Monitoring

• Real-time measurement via gas, water and electricity meters
• Process parameters linked to product barcodes
• Complete traceability per product and batch

The results after commissioning are clear:

• 20% higher productivity thans to automatic routing
• Significant energy savings through heat recovery and insulation
• Optimal water reuse and lower consumption
• Better product quality due to optimal adhesion
• Complete traceability of every product
• Enhanced safety and working comfort for operators

With this investment, Harinck posesses a powder coating line unique in Belgium, successfully achieving its objectives regarding productivity, sustainability, traceability, and safety without compromise.
