| 1 | Required Output | Choose a machine capacity that covers normal demand plus approximately 15–25% growth. | A small capacity gap can create delivery delays, while excessive capacity increases equipment and operating costs. | Rated cycles per minute, cavities per mold, operating hours per day, and expected utilization rate. | High |
| 2 | Cup Lid Diameter and Geometry | Define the lid diameter range, stacking profile, sealing edge, drinking opening, and any custom features before selecting the forming area. | Tooling and forming stations must match the lid design. Small dimensional differences can affect cup compatibility and sealing performance. | Maximum forming area, mold dimensions, product height, trim tolerance, and changeover requirements. | High |
| 3 | Material Compatibility | Select equipment compatible with the intended sheet or roll material, such as PP, PET, PS, PLA, or other approved thermoforming materials. | Different polymers require different heating profiles, forming conditions, and cooling times. | Material range, sheet thickness range, heater control zones, forming method, and recycled-content compatibility. | High |
| 4 | Production Method | Match the machine type to the required process: thermoforming, injection molding, or compression forming. | The process affects tooling cost, cycle time, material usage, product consistency, and the range of possible lid designs. | Process sequence, mold structure, trimming system, cooling method, automation level, and scrap handling. | Medium |
| 5 | Automation and Labor | Use automatic stacking, counting, conveying, and scrap collection when continuous production and low manual handling are required. | Automation can improve repeatability, reduce handling errors, and support stable output during long production runs. | Automatic feeding, product counting, stack height control, conveyor layout, sensor systems, and operator requirements. | Medium |
| 6 | Utilities and Factory Space | Confirm electrical supply, compressed air, cooling water, ventilation, floor loading, and access space before purchase. | Insufficient utilities or restricted installation space can reduce machine performance and increase commissioning time. | Installed power, voltage and frequency, air pressure, cooling capacity, machine footprint, and maintenance clearance. | Medium |
| 7 | Quality, Safety, and Maintenance | Prioritize stable temperature control, reliable sensors, guarding, accessible maintenance points, and documented operating procedures. | Consistent process control helps maintain lid dimensions, sealing performance, appearance, and production uptime. | Temperature accuracy, alarm functions, emergency stops, guarding, spare-parts availability, maintenance intervals, and training support. | High |
