It has been a busy year for Rajoo Engineers Ltd., as the Indian maker of extruders and film and sheet extrusion equipment closed three deals with companies from Italy, Germany and its home country that greatly expand Rajoo's product offering and technology.
The company, based in Rajkot, India, closed all three business deals in 2010. One of the deals a joint venture with Bausano & Figli SpA, an Italian maker of pipe and profile extruders will help Rajoo serve an important market in booming India.
There is a lot of development in infrastructure already in India, like real estate and buildings and roads, said Rajoo Chairman Chandrakant Doshi. And they all require pipe and also profiles. This company will be providing for pipelines.
The other two deals involve a technical collaboration with Hosokawa Alpine AG that was announced 10 days before K, and a merger between Rajoo and Wonderpack Industries Pvt. Ltd., a Nashik, India, maker of thermoforming machinery.
Doshi outlined the strategy during an interview at Rajoo's booth at K 2010 in Dusseldorf, where Rajoo grabbed attention by extruding sheet from 100 percent recycled PET.
Doshi said the Rajoo/Wonderpack business is moving forward. Wonderpack had its own booth at the K show.
In the pipe and profile machinery arena, Rajoo will begin building extruders in January, in a building in Rajkot, India, that is separate from its headquarters plant, Doshi said. Initially, 10 people will work at the business, called Rajoo Bausano Extrusion Pvt. Ltd. The plant will employ about 60 at maximum production.
Bausano, based in Rivarolo Canavese, Italy, owns 51 percent of the joint venture; Rajoo owns 49 percent.
Rajoo Bausano will sell extruders in India, Africa and Southeast Asia. Doshi said this will be Rajoo's entry into extrusion systems for pipe, profile and wood-plastic composites. Rajoo's headquarters plant will produce many of the parts for Rajoo Bausano Extrusion.
The majority of the manufacturing and the assembly will be outsourced to Rajoo, he said. Components will be manufactured by Rajoo, will be sold to Rajoo Bausano, and Rajoo Bausano will build the machines.
The equipment offering includes pipe extruders for PVC, polyethylene and polypropylene. The joint venture is promoting its longer extruders, with length-to-diameter ratios of 30-1, which officials said improves melt homogenization at much higher outputs using an extruder and motor similar in size to the standard Indian size of 18-1 to 20-1.
Doshi said vacuum sizing technology, offered on Rajoo Bausano lines, is another improvement for India, since the technology extrudes pipe with a smooth inner surface so fluid flows through easily. He said existing pipe extrusion systems in India use the floating bung technique, which yields a rough inner surface.
These are at least 20-25 years old, whatever machines are in the market, he said.
On the blown film front, Rajoo is working with Hosokawa Alpine of Augsburg, Germany. We will be developing a hybrid model of a blown film line where some of the parts and technology will come from Hosokawa and some of the parts will be incorporated and manufactured by Rajoo, Doshi said.
Rajoo will assemble the equipment in Rajkot. The goal is to create better-quality, but affordable, blown film lines that Rajoo will sell to customers in India, Nigeria, Ghana, Kenya and Tanzania.
Rajoo already makes blown film lines, but Doshi said the new combined-technology line will be at a higher technical level that Rajoo equipment, at a lower price than Alpine.
We have very good blown film lines. But in India there are customers who will be buying only European lines, Doshi said.
He said Rajoo also will supply some subassemblies to Hosokawa Alpine's factory in Germany, giving Alpine a lower-cost sourcing option.
At K, Rajoo's recycled-PET sheet line was equipped with crystallizing, drying and materials-handling equipment from auxiliary equipment maker Conair Group Inc.
The Rajoo line produced 271/2-inch sheet at a rate up to 660 pounds an hour. Conair of Cranberry Township, Pa., operates a joint venture company in Ahmedabad, India, called Nu-Vu Conair Pvt. Ltd., and that operation negotiated the contract with Rajoo.
For the K show line, Conair supplied a Model CR42 crystallizer, a Carousel Plus dryer, drying hoppers with temperature control, DuraLoad hopper loaders and and filterless material receivers.
