The SQ-20~200L Large Accumulator Blow Molding Machine is designed for high-efficiency production of 20–200L large hollow plastic products. It uses an accumulator head and supports multi-material feeding from two directions, with optional configurations such as double-layer/low-flow head to match different product requirements.

Built for stable quality control, the machine features PLC control with a touch-screen HMI and a multi-point parison controller for wall-thickness management across different products. It also supports multiple special functions, including up & down, material support, inside/outside thread rotation demolding, sub-mold open/close, auto sealing, and auto take-out (manipulator).
