BI Axial Rotomolding Machine


Vishnu Engineering’s BI Axial Rotomolding Machine is one of our most dependable offerings a machine we have refined over two and a half decades of working directly with plastic manufacturers. The biaxial rotation mechanism rotates the mould simultaneously on two perpendicular axes during the heating cycle, which is what gives rotomoulded products their characteristic seamless, hollow structure and even wall distribution. There is no simpler or more effective way to produce large hollow plastic parts.
The machine completely handles LLDPE and HDPE materials with ease, making it the appropriate fit for water tanks, chemical containers, playground equipment, and industrial storage. Our design also prioritizes heat uniformity every point of the mould sees consistent temperature exposure, which means fewer rejections, fewer thin spots, and a stronger finished product. The control system is PLC-based, so operators can set parameters, monitor cycles, and maintain repeatability without relying on guesswork.
Where Vishnu Engineering differs from many other suppliers is in the after-sales support. We have customers who have run our rotomolding machines continuously for over 20 years. The machine is built purely from heavy-duty steel with components sourced for longevity, and our service team is available when you need them.

FAQs
Biaxial rotation distributes molten plastic across every surface of the mould simultaneously top, bottom, sides, and corners. Single-axis machines cannot achieve the same uniformity, which leads to thicker walls at the base and thinner walls at the top. For water tanks and containers that need to hold pressure and load, biaxial rotation is the right approach.
Yes. Our multi-arm configurations permits different mould sizes to run simultaneously. Each arm can carry different product moulds, which improves throughput and reduces idle time between batches.
Output completely depends on the product size and cycle time, but most operators running our biaxial rotomolding machine can complete 12 to 18 cycles per 8-hour shift for standard tank sizes. Larger tanks take longer per cycle, but the numbers stay strong.
