AI Technical Summary
Existing plastic bottle molding technology suffers from problems such as uneven preform heating, asynchronous cooling, and poor air blowing synchronization, resulting in uneven wall thickness, numerous molding defects, low finished product qualification rate, low production efficiency, and high energy consumption, which cannot meet the needs of high-speed and high-quality production.
The plastic bottle blow molding system employs zoned precise preheating, multi-stage air blowing, and internal and external composite cooling. Combined with PLC control, it achieves precise temperature control of various parts of the preform, synchronized blowing, and improved cooling efficiency. Through zoned infrared heating, multi-stage air path control, and closed-loop cooling technology, the plastic bottle molding process is optimized.
It significantly improves wall thickness uniformity and finished product qualification rate, shortens molding cycle, reduces energy consumption, improves production efficiency, and meets the needs of high-speed and high-quality production.
