Fully Automatic 3-Layer Co-extrusion IBC Blow Moulding Machine for 1200L IBC Tank Making Machine Production

This HUAYU HYBM1200 3-layer co-extrusion extrusion blow moulding machine is specially engineered for mass production of 1200L HDPE IBC intermediate bulk containers and large-volume chemical plastic tanks. Built on mature blow moulding technology accumulated over years of research and field practice, this heavy-duty equipment delivers outstanding stability, reliable output and excellent product wall thickness control, making it a preferred solution for plastic container manufacturers targeting chemical storage, liquid transportation and industrial packaging markets.
The machine adopts a three-layer co-extrusion structure, which enables separate feeding and melting of different plastic materials for each layer. This layered design brings remarkable advantages over single-layer barrels. The outer layer provides great resistance against abrasion, weathering and ultraviolet radiation, protecting the tank surface from scratches and aging during outdoor storage and long-distance transport. The middle layer serves as the main structural support to guarantee sufficient mechanical strength and impact resistance of finished IBC tanks. The inner layer can use special barrier resin to achieve superb anti-permeation performance, effectively preventing leakage and chemical penetration when holding solvents, pesticides, industrial oils and various corrosive liquids. Customers can freely adjust the material proportion and thickness ratio of three layers according to their product requirements to meet diverse container standards and market specifications.
The extruder system is optimised for high and stable plasticising capacity. With precise temperature control across each barrel zone, raw materials are melted evenly without overheating or material degradation. The screw and barrel are treated with professional wear-resistant processing, extending service life and reducing maintenance frequency under continuous heavy-load production. The accumulator head is customised for large parison output, supporting uniform parison extrusion for 1200L large hollow products. It ensures consistent wall distribution across the whole container body, top and bottom corners, greatly lowering reject rates caused by uneven material flow.
For the clamping unit, this machine is equipped with a high-rigidity heavy-duty clamping frame. The hydraulic driving system supplies powerful and balanced clamping force, keeping moulds tightly locked during high-pressure blowing. The linear guide structure ensures smooth and accurate mould opening and closing, avoiding mould offset and flash. The wall thickness control system supports multi-point parison thickness adjustment in real time. Operators can set thickness curves via the human-machine interface, automatically adjusting material distribution to thin out redundant positions and reinforce high-stress areas of the tank. This intelligent control helps save raw material consumption while improving the impact resistance and load-bearing performance of final IBC tanks.
This fully automatic blow moulding machine supports continuous cyclic production. After mould closing, parison extrusion, blowing, cooling, mould opening and product ejection are completed automatically in sequence. Operators only need to monitor the system status and finish simple material feeding and finished part picking. The human-machine touch screen integrates all production parameters, including temperature, pressure, cycle time and wall thickness curves. All operation data can be saved and recalled for different moulds and product recipes, convenient for quick model switching and production management. Safety protection modules cover mould movement, hydraulic overpressure and abnormal alarm functions to protect operators and equipment during 24-hour non-stop operation.
The machine frame uses thickened welded steel structure with stress relief treatment, minimising deformation under long-term heavy work. Hydraulic components are selected from trusted global suppliers to maintain stable pressure output and low noise. Cooling circuits are reasonably arranged inside moulds to speed up product cooling and shorten each production cycle, lifting daily output capacity.
This HYBM1200 3-layer blow moulding machine is widely applied to produce 1200L IBC tanks for chemical industry, food-grade liquid packaging and waste liquid storage. Finished containers meet strict requirements for drop test, stack test and leakage inspection. HUAYU provides complete technical support including mould matching, installation guidance, on-site commissioning, operator training and long-term after-sales maintenance service. We also offer flexible customisation options such as modified parison head, special cooling system and upgraded control logic according to customers’ raw materials and product standards.
With low energy consumption, low failure rate and easy maintenance, this heavy-duty 3-layer co-extrusion blow moulding equipment helps plastic product factories cut production costs and obtain high-quality large hollow plastic containers. It is a cost-effective choice for enterprises expanding IBC tank production lines and upgrading from single-layer equipment to multi-layer barrier container manufacturing.
