Sridevi Tool Engineers Case Study

NX Sridevi Tool Engineers Increasing profitability through improved mold-making technology Industry A design process built on NX Industrial machinery Mold Design allows mold makers to realize productivity gains of Business challenges more than 50 percent and cost Profit margins eroding due to savings exceeding 40 percent increased competition Continuous improvement drives growth Automakers’ demands for Sridevi Tool Engineers Pvt. Ltd. (Sridevi) increasingly shorter cycle was founded in 1972 to manufacture times molds and dies. The company has Rigorous quality expectations prospered in both domestic and international markets ever since. In 1986, Sridevi was the first commercial tool shop Keys to success in India to adopt computer numerical In-house design process control (CNC) machining, a move that using NX gave the company a strong competitive Design that automates many advantage and helped it to grow at a much assurance system based on the ISO 9000 aspects of mold design faster pace than other tool shops in India. standard. Another aspect involved In 1998, Sridevi formed a joint venture changing the company’s design process Part-mold associativity that with Italy’s second-largest tool company, from one provided by an outside vendor speeds design changes Comec S.p.A. Called Comec India, this and based on 2D computer-aided organization serves the European engineering (CAD) to an in-house 3D CAD Results automobile market. solution equipped with industry-leading mold design capabilities. Mold designs completed in Today, in addition to the automakers, half the time Sridevi provides molds to white goods “There were numerous drawbacks to the Mold development cost and consumer products manufacturers. old process,” says Surendra C. Kalyanpur, savings of more than Customers include Honda, Yamaha, Sridevi’s managing director.

This involved, for design since that meant going back to the example, the implementation of a quality vendor. And once a design was complete, www.siemens.com/nx “Quality is tremendously important to Sridevi, and especially in this regard, the decision to go with NX has been very beneficial.” Surendra C.

In contrast to other automatically create portions of the mold, options they evaluated, NX™ software such as the cavity and the base,” notes V. from Siemens PLM Software met all of Veerapandian, assistant manager of design these requirements. “Other programs were at Sridevi. Designers add components such as electrodes and gates by selecting those parts from a component library, or using built-in tools to create them quickly. For example, to place a gate, they simply indicate the location and enter the specifications. NX Mold Design generates the geometry and inserts the gate into the model.
