The HYBM-300 is a dedicated residential water tank blow moulding machine optimized for the production of 300-liter HDPE rooftop storage tanks serving the rapidly expanding housing development markets across Southeast Asia.

Countries including Vietnam, Indonesia, the Philippines, Thailand, and Myanmar are experiencing unprecedented urbanization driven by rural-to-urban migration, creating sustained demand for 300L tanks as the standard rooftop water storage unit in mid-rise apartment buildings, townhouse developments, and single-family homes.

Unlike larger tanks that require structural roof reinforcement, the 300L format fits within the standard 300kg-per-square-meter live load rating of typical Southeast Asian reinforced concrete roof slabs, making it the default specification for residential architects and plumbing contractors throughout the region.

The machine features an integrated masterbatch dosing unit that enables precise control of UV stabilizer concentration in the outer tank wall, ensuring a service life of 12 to 15 years under the intense equatorial sunlight conditions that characterize Southeast Asian climates from the Mekong Delta to the Java Sea coast.

• Integrated UV Stabilizer Dosing: A volumetric masterbatch dosing unit mounted on the extruder feed throat delivers precisely metered UV stabilizer concentrate at 2% to 5% by weight, ensuring every tank meets outdoor service life requirements without the material waste of pre-compounded UV-stabilized resin grades.
• Rooftop-Optimized Tank Geometry: The 200-point radial parison programmer stores a pre-configured wall thickness profile for the 300L tank geometry with reinforced dome and base corner sections, producing tanks that withstand the 0.3 MPa hydrostatic pressure at the tank base when filled without excessive wall thickness in lower-stress upper sections.
• High-Humidity Electrical Protection: All control cabinets are fitted with thermostatically controlled anti-condensation heaters that activate automatically when the machine is powered down, preventing moisture ingress and electrical corrosion in the 80%+ relative humidity environments typical of Southeast Asian factory conditions.
• Quick-Release Mold Mounting: The hydraulic mold clamping system with quick-connect fittings enables changeover between 200L and 300L tank molds in under 45 minutes, allowing manufacturers to serve multiple customer specifications from a single machine.
• Local Language HMI Support: The HMI interface supports Vietnamese, Bahasa Indonesia, Thai, and English language options, reducing operator training time and minimizing the risk of parameter entry errors by non-English-speaking machine operators.
