Loft Tank Roto Mould Manufacturer

Loft Tank Roto Mould Manufacturer

Vishnu Engineering manufactures Loft Tank Roto Moulds for plastic tank producers who supply the residential construction and real estate markets. Loft tanks also called overhead storage tanks re one of the highest-volume plastic products in India, and the quality of the mould directly determines the quality and marketability of the finished tank. We have supplied loft tank moulds to manufacturers across the country for over two decades.
Loft tanks are installed in roof spaces, on rooftops, and in overhead positions where space is sometimes tight and the tank needs to fit specific architectural constraints. Our moulds accommodate a range of loft tank profiles standard cylindrical, flat-top, low-profile, and triple-layer designs. The triple-layer loft tank is now a strong market segment, and we manufacture moulds specifically for multi-layer production that incorporate the internal insert cavity for the middle layer of black LLDPE, which provides UV protection.

All Vishnu Engineering loft tank moulds are manufactured from aluminium alloy, CNC machined, and tested before delivery. We include thread rings, lid seat profiles, overflow ports, and inlet/outlet fittings as standard design elements. If you want your brand name or tank capacity embossed on the finished product, we incorporate that into the mould at no additional complexity.
