2200L 6-Layer Co-Extrusion IBC Blow Moulding Machine with Surface Modification Function for High-Barrier IBC Tank Making

Huayu 2200L 6-Layer Co-Extrusion Blow Molding Machine represents our flagship large-volume hollow molding equipment, built on more than 20 years of manufacturing experience in the blow molding industry. This model is specially developed for producing high-performance 2200L multi-layer plastic hollow containers that require barrier, anti-ultraviolet, anti-static and chemical-resistant properties. It meets strict packaging standards for chemical raw materials, industrial reagents, food-grade liquid storage and special hazardous substance packing, filling the demand for large-capacity multi-layer containers in the global market.

The six-layer co-extrusion structure is the core advantage of this machine. Each layer can adopt different plastic raw materials according to customer formula design, including HDPE, barrier resin, adhesive resin and functional modified materials. Independent extrusion units are configured for every layer, with stable feeding, uniform plasticization and consistent melt temperature. The separate extrusion control system avoids material mixing and layer thickness deviation, ensuring each functional layer can play its designed role. Compared with single-layer or three-layer containers, six-layer products have greatly improved barrier performance against oxygen, water vapor and chemical solvents, extending the shelf life of stored contents and reducing leakage risks.

Precision wall thickness control system guarantees stable container forming quality. It adopts high-response servo hydraulic drive and professional wall thickness controller. The operator can set wall thickness curves at different positions of the parison through the touch screen. The system tracks and adjusts the die gap in real time during extrusion, effectively solving common defects such as uneven wall thickness, local thin spots and deformation after cooling. Even for large 2200L heavy containers, finished products maintain uniform stress distribution, stronger impact resistance and stable stacking performance. The finished barrels can pass strict drop test, hydrostatic pressure test and long-term stacking aging test.

The machine frame and mold clamping unit adopt heavy-duty welded and processed structure, with high rigidity and strong anti-fatigue capacity. The large clamping force ensures tight mold closing without flash during high-pressure blowing. The mold base supports customized mold installation according to customer product drawings. We provide matched mold development, processing and debugging services together with the host machine. The blowing system uses stable air circuit design, with adjustable blowing flow and pressure, which can adapt to different resin characteristics and product structure requirements.

Intelligent human-machine interface simplifies daily operation and parameter management. All production parameters, including extrusion speed, temperature zone setting, parison speed, blowing time and clamping cycle, can be saved as product recipes. Users can call the recipe with one click when switching products, greatly shortening trial production time. The system integrates fault alarm and record function. When abnormal temperature, pressure or action occurs, the screen will pop up corresponding prompt information for quick troubleshooting, reducing unexpected downtime.

Energy-saving design runs through the whole equipment. The servo power system only outputs required power according to working actions, cutting idle energy consumption obviously compared with traditional constant pump hydraulic systems. Heating zones are equipped with thermal insulation covers to reduce heat loss. Reasonable layout of extrusion channels reduces melt residence time, avoiding material degradation and saving raw material cost. It is suitable for continuous 24-hour stable production for medium and large factories.

We provide full turn-key support for this 2200L six-layer blow molding project, including formula suggestion, mold making, on-site installation, commissioning, operator training and after-sales maintenance service. Whether you build a new production line or upgrade old equipment, we can customize the configuration to match your target products and budget. This machine is a reliable choice for customers who pursue high barrier large hollow containers, helping manufacturers produce competitive products and expand business in the high-end industrial packaging market.
