APL Apollo, a leading tube manufacturer in India, contracted Fives for two OTO hollow shape universal forming mills (OTO HSU) for its manufacturing facilities in Raipur (Chhattisgarh state) and Murbad (Maharashtra state).
The OTO HSU tube mill has been specifically designed to produce square and rectangular tubes for the construction industry. The mill produces HSS (hollow structural section) tubes by direct forming, skipping the traditional step of constructing round tubes and then squaring them. The range of products can vary from a minimum size of 20x20 to a maximum size of 120x120mm within a range of four mills, with a maximum production speed of 120m/min.
Main benefits of OTO HSU technology:
- Frequent and fast production changeovers due to the universal design (no rolls change)
- Covering a wide range of dimensions and thickness
- Very fast set-up time due to the high automation level and technology
- Reduced production cost
- Average material saving around 3-4%
