Heavy-Duty CNC Electric Paper Cutter

The customer is a printing and packaging group/distributor in the *** region. Through the *** distributor, within *** months, they purchased from our company in *** batches: 18 wireless perfect binding machines, 12 PUR perfect binding machines, 9 heavy-duty hydraulic paper cutters, 15 hydraulic paper cutters, 22 electric paper cutters, 8 automatic label carton die-cutting machines, and 14 print laminating machines, totaling 98 units. The equipment is distributed across *** production bases and *** warehousing centers, involving *** machine operators, *** maintenance personnel, and *** customer service staff. After the project was put into operation, due to high operator turnover, the coexistence of multilingual teams, and inconsistent parameters across sites, problems such as pages falling out after perfect binding, PUR temperature setting deviations, cutting size drift, lamination bubbles, improper die-cutting pressure and waste removal settings, and chaotic maintenance cycles occurred. In the first month after launch, after-sales consultations reached more than 3,200, on-site services totaled 126, and work orders reached 1,860. The customer requested systematic batch training.

Our company has launched a special cross-regional training service initiative: 1) Establish an 8-person training and process team, first conduct remote surveys of *** stations and collect *** job questionnaires; 2) Develop 6-level courses based on 7 types of equipment, covering basic operation, changeover and adjustment, parameter recipes, daily maintenance, safety standards, and troubleshooting; 3) Use 12 online live broadcasts, 7 recorded course sets, and 45 days of on-site residency, covering *** stations in 6 batches, and provide multilingual illustrated manuals, operation video QR codes, inspection checklists, and parameter cards; 4) After training, conduct theoretical and practical assessments, issue authorized work certificates to those who pass, and establish training files; 5) Set up a remote support group and a monthly retraining mechanism, unify parameter standards such as glue binding/PUR temperature, cutting pressure, lamination temperature and speed, and die-cutting pressure, and assist customers in establishing spare parts and maintenance plans.

***National*** Regional *** Printing Group has deployed our wireless perfect binding machines, PUR perfect binding machines, heavy-duty hydraulic paper cutters, hydraulic paper cutters, electric paper cutters, automatic label carton die-cutting machines, and print laminating machines in batch across *** factory areas, totaling 286 units. Due to continuous 8 months of three-shift high-load production, batch concentrated failures have occurred: temperature control drift and glue pot coking in wireless perfect binding machines, glue path blockage and inaccurate metering in PUR perfect binding machines, insufficient pressure and oil cylinder leakage in heavy-duty hydraulic paper cutters, paper pusher positioning deviation in electric paper cutters, uneven pressure in die-cutting machines, and temperature fluctuation and roller surface damage in laminating machines. The failures have affected *** production lines, impacting daily delivery by approximately *** ten thousand copies/boxes, and the customer requires batch repair to be completed within *** days.

Launched a special after-sales mechanism for major overseas customers, established an 18-person repair team, first completed preliminary screening of 286 devices through remote diagnostics, and identified *** types of high-frequency faults; allocated 3,860 sets/pieces of spare parts including heating tubes, temperature control modules, PUR glue path components, hydraulic seals, oil pump valve groups, paper cutting knife pads, die-cutting steel plates, and laminating rollers from the *** central warehouse and *** spare parts warehouse, and air-freighted them to *** in 3 batches; dispatched 12 engineers to the *** factory, and carried out rotating repairs across 7 plant areas according to three-shift schedules and downtime windows, completing temperature control calibration, glue path cleaning, hydraulic pressure-holding testing and seal replacement, paper cutting precision calibration, die-cutting pressure balancing, laminating temperature uniformity adjustment, and firmware upgrades; simultaneously delivered operation SOPs, preventive maintenance sheets, and on-site technician training.

***Region*** agent feedback: The 860 units of equipment it supplied to *** printing plants, including perfect binders, PUR binders, heavy-duty hydraulic paper cutters, hydraulic paper cutters, electric paper cutters, automatic label carton die-cutting machines, and print laminating machines, generated 326 after-sales work orders in a concentrated period before the *** peak season. The main issues include: glue temperature fluctuation and glue layer stringing on binding machines, hydraulic alarms and cutting precision deviation on paper cutters, unstable temperature/tension on laminating machines, and registration offset on die-cutting machines. Customer *** contact requested remote batch processing to avoid downtime affecting delivery deadlines.

Our after-sales team activated the emergency response plan for remote technical support, grouping by product line and conducting batch troubleshooting through remote video, remote diagnostic tools, and an online ticket system. We guided customers to check the power supply, air supply, hydraulic oil level, glue pot temperature sensor, knife pad, laminating pressure roller, tension parameters, die-cutting plate pressure, and positioning sensor; remotely assisted in restoring parameters, upgrading firmware, resetting PLC alarms, and cleaning and calibrating sensors. For 860 units of equipment, we issued a batch processing list, provided multilingual SOPs, operation videos, and inspection checklists, and conducted 8 online training sessions for more than 60 terminal operators. For equipment requiring replacement parts, after verifying the model, *** overseas warehouse arranged shipment.
