Modern refrigerator manufacturing covers multiple complex processes such as box sheet metal processing, polyurethane foaming, door body (glass/metal/composite material) assembly, compressor/condenser/evaporator and other core components integration, refrigeration system leak detection and performance testing, and needs to meet the customization needs of different scenarios of “domestic (single door/double door/multiple door)+ commercial (freezer/display cabinet)” at the same time.
Traditional production lines often face the following core problems:
- High structural complexity: The size of the box and door body of a multi-door refrigerator (such as French four-door, opposite door) is greatly different, and the thickness accuracy of the foam layer is required to be ± 1mm (directly affects the insulation effect). Traditional manual positioning can easily lead to deviations;
- Strict energy efficiency and safety standards: Major global markets (such as EU ERP, U.S. DOE, and China’s new energy efficiency standards) have mandatory requirements on refrigerator power consumption, noise value (≤ 40dB), and leakage volume (≤5g/year) of refrigerants (such as R600a fluorine-free environmentally friendly refrigerant), making it difficult to accurately control ordinary processes;
- There is an urgent need for flexible production: consumers prefer rapid iteration (such as embedded refrigerators and zero-embedded designs), and the same production line needs to be compatible with rapid switching of different volumes (180L-600L) and different door materials (glass/stainless steel)., the replacement of traditional production lines takes as long as 2-4 hours;
- It is difficult to control the quality of key processes: the foaming process requires precise control of temperature (±2℃), pressure (±0.05MPa) and material ratio (black material/white material ratio). The installation accuracy of door body hinge/drawer rail affects the service life, and manual testing is easy to miss.
In response to these pain points, the refrigerator assembly line focuses on “process adaptation + intelligent control”, providing global refrigerator manufacturers with one-stop solutions from “single equipment” to “full-process production lines” to help produce more efficient and products. More reliable and more flexible in switching.
