Industrial Trip to Goa
February 24, 2007 § 1 Comment
Our class of B.E. COMPS (2006-2007) went on an industrial trip to Goa from 16th of Feb, 2007 to 19th of Feb, 2007. The industry we visited in the course of the trip was Nebula Home Products Ltd. The company specialises in the design and manufacture of Printed and E-Fluted Cartons. The company was established in 1996 and today is a leading name in the field of manufacturing and supply of packaging products. Nebula manufactures printed cartons for some of the most popular and well known brands in India, namely Colgate, Nestle, Philips, Balsara and Kodak, among many others.
We visited the company’s premises in the Pilerne industrial estate in the town of Bardez in Goa. The facility is spread out in 11,800 square metres and has a built up area of 3000 square metres. The company is situated in a very spacious environment and the working conditions are extremely good. On entrance into the company we were given disposable caps, much like shower caps, as it is compulsory in the premises around the machines, which allowed for protection both for the ink and our hair, in case of any eventuality with the inks in the machines. The company boasts of a full start to stop processing of the cartons right from the time it is unprocessed cardboard to the high quality packaging that we see on Colgate toothpaste. We got to see the full repertoire of machines that the company employs in the manufacture of the cartons. As they specialise in both design and manufacture, we were first shown the design process by our escort. He explained about the ‘positives’ that are first made out of the final design and are printed out onto a special plastic sheet. By using these positives, the designs are transferred onto the packages, much like what is done with negatives in the case of photographs. The designs are then transferred onto printing machines. The printing machines are the state of the art Roland Printing Machines. The company has 3 variants of these machines. These are 2 colour offset, 4 colour offset and 6 colour offset machines. These machines vary in the number of colours that can be put on the packaging and quality that offset printing guarantees. These machines are extremely precise and fast. After the printing comes the coating process. The paper has to be coated in a variety of ways to achieve the quality that enamours customers. Various types of printing and coating styles are practised at Nebula. Chief among them being the Emboss in, Emboss out, Scum print, Rough cut print, corrugated prints etc., in all they make around 9 different varieties depending on customer needs. The coating machines used are either UV based or water based, sourced from countries like Taiwan. We were shown the gloss coating process on one of the machine, which was a very interesting sight. The end product after printing and coating is a huge, almost A2 size cardboard which contains a lot of packaging material (depends on size of package). This has to be cut down to size. This is done by the die cutting machines. There are 4 types of machines for this with 2 hand operated and 2 automatic. These machines cut the cardboard to size of the actual packages. From here on the process moves to the seperation operation where individual packages are separated by workers and put back into the manufacture line. The next process is gluing, with bottom gluing machines and also manual gluing. Here is where the process ends and the packages are readied. There were some other machines which were part of the setup and are used when required, these include a Hot Foil Stamping Machine, Corrugation Machine, E-flute Pasting Machine etc. The last machine we got to see was a huge CNC machine which was used in the process of printing. The machine had its own temperature controlled room with its own crew working on it. It was a fully automated machine with a computer panel which showed information about the various parts of the machine and the status of jobs. The computer equipment was impressive. We ended the tour of the company premises with a vote of thanks for our escort by our H.O.D Prof. Manoj Sankhe.
Our visit to the industry was very fruitful from the point of view of learning about a process which we had little knowledge about. We got to learn a lot by watching the various machines in action. The trip was especially fruitful for the students of robotics elective as they got to see the machines and elements they learn about. All in all, the trip was a very good experience for us.
We are thankful to the college authorities, our departmental staff who accompanied us and the Nebula management for making this trip possible.
