KUKO engages with every project from the initial application review. We assess product characteristics, packaging format, film type, required output, operating speed, and upstream and downstream equipment interfaces to ensure the machine configuration aligns with your production process.
Throughout manufacturing, rigorous build-quality inspections, configuration validation and pre-shipment trial preparations are systematically managed and reviewed with the customer to achieve full mutual alignment. KUKO additionally manages the full scope of technical documentation compilation, export compliance documentation, installation scheduling, on-site commissioning, operator training handover and ongoing after-sales support. Every set of documentation and service provision is formally defined and confirmed for each individual project enquiry.
Product drawings, photos, samples, proposed packaging method, pack patterns, film specifications, line-layout files, and a video of the existing production line will help KUKO confirm sealing method, tunnel size, interfaces, and the most suitable configuration before pricing.
