Xinhengda has rolled out a professional extrusion blow molding machine purpose-built for plastic water tank production.
Equipped with premium FIFO accumulator head, MOOG parison thickness regulator and servo hydraulic drive, the system supports 1 to 5-layer co-extrusion and automated manufacturing of plastic tanks ranging from 20L to 10000L. Adopting PLC and touchscreen HMI together with robotic finished part pick-up, the machine works perfectly with HDPE resin to balance high output and low energy use.

The equipment brings remarkable economic benefits for tank producers. Compared with enamel liner production lines, it cuts raw material costs and lifts molding efficiency. Plastic liners made on this machine deliver better thermal insulation than stainless steel alternatives to save long-term operational energy.
Thanks to precise wall thickness calibration, integrally molded liners have seamless structure with great sealing, corrosion and aging resistance. Fitted with top-brand components, the machine maintains stable continuous operation and reduces reject rates.

Boasting fully automatic control and user-friendly HMI, the unit is easy for new operators to master. Its optimized mechanical layout facilitates routine maintenance, backed by reliable after-sales support to reduce enterprise operating expenses. Customizable machine configurations are available for producing 120L–1500L inner tanks, meeting varied demands from solar equipment manufacturers.

Widely applicable to civil water storage, industrial liquid handling and new energy sectors, this blow molding solution offers manufacturers a flexible, high-efficiency production option.
