                          \n
                        1. Hourly capacity of upstream AEM-450 extruder to match corresponding roller quantity model;<\/li>\n
                        2. Foamed sheet thickness and foaming ratio, prioritize 9\/11 wheel models for thick high-foaming materials;<\/li>\n
                        3. Workshop length, width, height and floor load capacity to verify machine overall dimension and weight;<\/li>\n
                        4. Whether factory cooling water supply pressure reaches 2MPa standard.<\/li>\n<\/ol>\n<\/div>

                          Q26: Can the working width of cooling cutting machine be widened after delivery?<\/span><\/strong><\/p>\n

                          A26:Standard unified 900mm working width, rollers, belts and frame are all prefabricated according to 900mm width and cannot be widened after delivery. Custom widened full machine plan with matched wider exhaust fan must be confirmed during model selection if wider sheets are required.<\/p>\n<\/div>

                          Q27: Can roller quantity be increased or decreased after machine delivery?<\/span><\/strong><\/p>\n

                          A27:The frame length, double-layer support and cooling water pipelines of 5\/7\/9\/11 wheel models are independently customized by mold. Roller quantity is fixed before delivery and cannot be refitted later. However, exhaust fan remains standard equipment no matter which model is selected, no addition or removal required.<\/p>\n<\/div>

                          Q28: What production problems will be caused by insufficient cooling water pressure?<\/span><\/strong><\/p>\n

                          A28:When water pressure is lower than 2MPa, internal roller water circulation slows down leading to insufficient sheet heat exchange, inadequate cooling and sheet warping with uneven internal stress. Even with built-in standard exhaust fan, insufficient cooling still causes dimension deviation after cutting and higher rejection rate.
