I. Core Hardware Component Verification
1. Transmission Structure: High-quality models employ a full servo drive, chainless transmission design, paired with a patented semi-circular turning bearing turntable. Even under long-term high-speed operation, issues such as misalignment and excessive bearing wear will not occur. Inferior models often use ordinary chain drives, which will exhibit significant vibration and misalignment after 1-2 years of operation.
2. Frame Material: High-quality equipment uses a thickened pure sheet metal frame, precision machined to reduce welding stress, making it resistant to deformation over long-term use and with a service life of over 20 years. Low-priced models often use ordinary square tube and aluminum profile structures, which are prone to deformation under stress and have a service life of only 2-3 years.
3. Core Components: Priority is given to models equipped with industrial-grade Ricoh/Epson printheads, imported servo motors, and low-voltage electrical components from brands such as Chint. The ink path system features a complete white ink circulation and filtration function, significantly reducing the probability of printhead clogging.
II. Actual Operation Status Testing
1. Conduct a full-load continuous printing test on-site, running continuously for more than 2 hours. Observe whether the equipment exhibits significant shaking or abnormal noise, and whether the actual production capacity reaches more than 90% of the nominal value, avoiding purchasing equipment with "falsely advertised" capacity.
2. Check the equipment's automation functions: whether it supports fault self-diagnosis, production data statistics, and remote parameter adjustment. High-quality models are equipped with an industrial-grade PLC control system, which can significantly reduce the operating threshold and troubleshooting time.
III. Verification of Printed Finished Product Effect
1. Test multi-color printing accuracy, continuously printing 100 patterns. The color registration error should be stably controlled within 0.2mm, with no significant misalignment.
2. The finished printed product must meet the requirements of abrasion resistance and water resistance. After multiple washes, the pattern should not fade or crack, the ink layer should be uniform without smudging, and the white ink on dark fabrics should be evenly laid down without whitening or bleed-through.
IV. Manufacturer Qualifications and After-Sales Support
Prioritize original manufacturers with multiple invention patents and utility model patents, rather than OEM assemblers. These manufacturers offer more reliable equipment processing precision and quality control. Also, confirm whether the manufacturer provides localized 48-hour on-site service, a free warranty period, and a comprehensive spare parts inventory to avoid delays in repairs and long-term downtime losses in case of malfunctions.
