1000L High-Output HDPE Water Tank Blow Moulding Machine for Southeast Asian Rainwater Harvesting Systems

The HYBM-1000H is engineered as a high-output extrusion blow moulding solution dedicated to 1000-liter HDPE water storage tank production, with particular optimization for the rapidly expanding rainwater harvesting market across Southeast Asia.

Countries including Indonesia, Vietnam, Thailand, and the Philippines are implementing national rainwater collection mandates that drive sustained demand for 1000L tanks in both residential and community-scale installations.

This machine delivers an impressive throughput of 14 to 18 finished tanks per hour when running a standard 6kg tank configuration with 1.5mm nominal wall thickness, translating to over 40,000 tanks annually in a single-shift operation.

The extruder features a 100mm barrier screw with a 32:1 L/D ratio that provides superior melt homogeneity, which is essential for tanks deployed in tropical climates where polyethylene undergoes significant thermal expansion and contraction cycles throughout the day.

• Exceptional Throughput Rate: The 260kg/h extrusion capacity paired with a 12-liter accumulator head enables consistent cycle times of 180 to 220 seconds for 1000L tanks, yielding 14 to 18 units per hour depending on wall thickness specification and ambient factory conditions in tropical Southeast Asian environments.
• Barrier Screw Technology: The 100mm diameter barrier screw with 32:1 L/D ratio incorporates a Maddock mixing section that eliminates unmelted resin pockets, delivering melt temperature uniformity within ±2°C across the parison. This directly improves tank burst pressure consistency by 15% compared to conventional single-flight screw designs.
• Tropical Climate Optimization: The hydraulic cooling system is oversized by 40% relative to temperate-climate designs, incorporating a plate-type heat exchanger and dual cooling fans rated for continuous operation at ambient temperatures up to 45°C, which is typical for factories in Jakarta, Ho Chi Minh City, and Bangkok.
• Multi-Layer Ready Architecture: The extruder platform supports future upgrade to a two-layer co-extrusion configuration by adding a secondary 45mm extruder module. This enables production of tanks with a virgin inner layer and recycled-content outer layer, reducing raw material costs by up to 25% for non-potable water applications such as irrigation and toilet flushing.
• Integrated Leak Testing Station: An optional in-line pneumatic leak testing module performs automated 0.5 bar pressure-hold testing on every tank immediately after demolding, rejecting defective units before they enter the deflashing station. This eliminates post-production quality inspection labor and reduces field failure claims.
