Moulding Expectations – Die & Mould Feature
The capital goods industry largely believed to be a barometer of a country’s economic growth, has vital support from the die and mould industry. With major global and Indian players ramping up their manufacturing operations within the capital goods industry in India to take advantage of initiatives like Make in India and export to regional markets, the Indian die and mould industry is experiencing a sharp rise in demand pointing towards a significant growth potential in years to come. The focus is on shedding traditional ways of doing business and adapting to changing times, where customer expectations are in focus and more value creation is sought and achieved.
The Die and Mould making industry in India has evolved through the years which have ensured that it is in a position to be able to compete on an international front. The demand for Die & Mould has been fueled primarily from automobiles, auto components, packaging, plastics, electronics, electrical, healthcare and machine tool industries and the growth of these sectors has seen a huge opportunity for the Die and Mould making industry in India. In fact with the globalization within the industry there has been a clear bent towards quality and the kind of moulds being used across different industries. The Indian tool room is also changing quickly as the industry is veering towards using CNC machining to manufacture. With precision and quality being the cornerstones of the business, the switch to CNC is all set to give the industry a competitive edge as well. D. K. Sharma, Executive Vice President & Business Head, Godrej Tooling explains, “the Indian Die and Mold making industry is currently at a stage where it has to come out from the cocoon of being a ‘mom & pop shop’ that was started by first generation entrepreneurs. It has to grow into an industrial outfit for continued growth and sustainability. Challenges are related to high investments and skills. The changing customer demands in Quality Control Delivery (QCD) have made the learning curve steep. As a corporate tool room, we are remodeling to address these challenges. We are all typically limited by the growth of the sectors we serve. Hence a 10-20% CAGR is the range in which all tool rooms aspire to frame their growth plans.”
With rapid globalisation, competition within the Indian industry is intensifying. Naturally newer technologies and efficient products is the norm as far as market expectations are concerned. “We have addressed it through three steps – closing the loop of technical collaboration for efficient product and better experience, focusing on value creation through digital levers rather than cost cutting, and incorporating a cycle of continuous learning in technology as well as execution,” says Sharma. As the Die & Mould industry needs the best surface finishing of the Die Mould machines, there are several new age technologies being seen. Adoption of high-speed machining and CAD technology enable reduction in the production time and cost of producing high precision surface finishes. One of these is the “SSS” of the Super Smooth Surface Technology that provides an optimal speed control function for machining die mould with a smooth surface. This technology also ensures high machining stability and quality with virtually no wrong impact from the cutting shape or speed. This is why SSS control is being sought after as it ensures both stable and high-quality processing, irrespective of the speed and shape command to achieve high quality processing. Also the finishing is smooth as there are no streaks on the processing surface despite the command shape that changes consecutively. The effectiveness of this technology can be seen from the fact that it reduces processing time and the conventional ratio 5:30% of time reduction (comparing with the same accuracy). Likewise with easy parameter setting, no requirement of parameter adjustment for correction of shape and easy adjustment for Efficiency-oriented and Accuracy-oriented needs, this makes it a technology that is easy to apply as well. Adoption of high-speed machining and CAD technology enable reduction in the production time and cost of producing high precision surface finishes. Since the right design is of paramount importance the industry is also increasingly using proper CAD/CAM solutions as the risk of error is minimised when the process is automated giving very less scope for manual intervention. CAM solutions to create a machining program use approximating the minute line segments for the motion curve of the tool relative to the workpiece and ant small error is mostly included in the data of minute line segment.
High Speed Machining or HSM is another much favoured technology as it helps in reducing the production time and cost of producing high precision surface finishes. This apart, the tool life is also extended especially if there is good care to tailor and balance the tool. Likewise, rapid tooling is a technology that aims to reduce cycle times by 40% as compared to conventional machining. This is executed by using conformal cooling, bimetal layering and better mould materials like aluminum, that allow quicker thermal conductivity inside the moulds. These rapid processes also ensure production of inserts and mould tooling in less than 48 hours. Rapid processes are also capable of producing modifications in the tool like undercuts or side-action easily. Again investing inm research and development activities to cater to the enhancement of value in newer products is a focus area. “We have dedicated a team of experienced designers and young achievers to explore innovative solutions based on future trends, product performance and customer feedback. In all our lines of business, we have invested through pilot projects related to future customer needs as well as product category, specific features in dies to enhance productivity and an extended after sales support which is a key input to close the loop for efficient products,” explains Sharma.
Cost competitiveness through shorter run times and productivity improvement are key deliverables for the industry. Tooling being a project type business, lead time is a direct function of capacity and project management skills. “We have adopted CCPM (Critical Chain Project Management) route of theory of constraints. We are now on a pilot project – flow improvement across the entire supply chain for a specific product category, expanding further to the entire operations. Our association as a partner is at two levels – new product development through dies and improvement in running dies to enhance productivity. The partnering for new product launches is most critical and we have graduated to a level where some of the OEMs in the automotive sector have placed their faith in us for new launches. There are learnings which will help serve this segment better,” says Sharma.
India’s thriving manufacturing sector has always been one of the largest employer of lakhs, but today things are looking different for the country’s manufacturers. Automation, advanced technologies and robotics are at the cusp of change in this sector. “The Government’s Make In India initiative is certainly laudable for bringing the sector into sharp focus, but without better infrastructure and availability of basic amenities, the initiative cannot take off as intended. The efficient removal of lengthy bureaucratic processes and quality training for a skilled workforce are essentials for long term success for both the Government and manufacturers. The government’s plans to develop industrial corridors and build smart cities with state-of-the-art technology and high-speed communication will all aid in bettering the manufacturing sector,” says Professor Elliott Weiss, Darden School of Business, University of Virginia. Despite various liberal government policies, the sector is yet to make a mark globally and 100% FDI in the tooling industry is certainly attracting steady investors. Consumer industries like automotive are seeing renewed demand especially in new technology and designs that has a direct correlation with increased demand for various innovative tools. The tooling industry that includes dies, moulds, jigs and fixtures plays an important role in manufacturing process across most industries. “As an organization, we welcome these initiatives as they generate huge opportunities. At the same time, they also pose bigger challenges in meeting the expectations of customers who have been used to get dies from an altogether different eco system. A bigger task of making manufacturing more attractive to the younger generation and managing digital transformation effectively is going to be critical for our industry. A number of things are happening simultaneously and we are constantly looking for opportunities to learn and serve our customers better. Unlike many other industrial products, tool making is an art. While every product requires passion, tool making takes it a level higher as it requires highly specialized skills. The challenge would be to maintain the passion and use technology for better tool making which the next generations can take forward,” says Sharma. Little wonder then that the focus on dies and moulds is going to remain a key aspect for all manufacturing industries. And this becomes more important as the number of large scale industries that need die and moulds is constantly on the rise.
