Our agility is derived from our proficiency to grasp evolving customer requirements. With a keen focus on understanding the unique needs of our clients, we aim to offer engineering excellence that forms an integral part of their supply chains and delivers immaculate value. It drives us to build processes and products that facilitate change, create one-of-its-kind products that lend us a competitive edge.

For years, we have steadily improved our manufacturing capabilities, introduced advanced technology and consistently fortified the entire value chain. In our relentless pursuit for excellence, we have strengthened every step of the organisational domain, from design and prototyping to production, packaging and logistics. With growing preference for precision engineered products, we are adopting methods to reduce redundant processes and aiming to sharpen our skills to align ourselves with emerging industry trends.

To support our growth objectives, we have relied on sustained capital expenditure to remain relevant and successfully tackle major shifts in industry preferences. At Pitti, we are enthusiastic about propagating agility across operations to make way for robust value creation and steer the organisation towards new growth paths.

We have also demonstrated our agility by efficiently responding to unexpected challenges. While the world remained in the throes of an unfathomable crisis in the year gone by, our resilience, perseverance and dedication empowered us to tide through tough times without a significant impact on financial performance.

Driving efficiency through agility

With continuous shifts in global value chains, consistent introduction of new-age technology and growing diversification of engineering applications, we are keen to sustain efficiency through agility.

We are demonstrating efficiency by developing manufacturing methodology that supports the delivery of customised products, the proficiency to offer superior quality products within close deadlines and our consistency in supplying products that can be easily inculcated in the customers’ production line. We consolidate quality responsibility at our end on the intergrated product. The cumulative capacities of the Hyderabad and aurangabad facilities enable us to significantly expand our product portfolio and integrate cutting-edge technology across operations. During the year under review, we have setup fabrication and shaft making lines for enhancing efficiency at our customers end. Over the years, we have built capabilities to punch, cut, machine and assemble components of higher complexities and integration with greater accuracy and lower tolerance levels.

We rely on agile processes, methods and facilities to deliver our competitive edge efficiently.

Creating niche market - ensuring customer delight
Rotor die casting with shaft assembly

The company used to supply finished laminations to customers which required further value addition in the form of core building, pressurizing and high-pressure die casting, shaft procurement from upstream suppliers and shaft assembly, air gap turning and grinding of bearing face. In addition to increased dependence on numerous suppliers, the customers faced issues with quality and timely deliveries. The Company realized the customers’ concerns and established an in-house manufacturing process for high pressure die casting, shaft manufacturing and assembly, and air gap turning. The ready-to-use rotor with shaft assembly enables customers to access superior quality products at better rates from a single supplier. It improved customer experience remarkably, strengthened relations with clients and improved the Company’s business prospects.

Built up rotor, shaft assembly, copper bar insertion and brazing

In order to further process the finished laminations offered by the company, customers had to avail the services of upstream suppliers for pressurizing the lamination core, procurement of shafts, copper parts copper bar insertion, machining & assembling. This not only increased operational hassles, it also affected the quality of products.

To avoid these issues, the Company revamped its manufacturing capabilities and processes for producing assembled copper bar rotors. It helped to build capacities for lamination core building, pressurizing, in house shaft manufacturing with modern CNC turn centers, stack pre heating and shrink fit assembly. Furthermore, the Company provided facilities for insertion and machining of copper bars, assembling of copper rings and brazing, air gap turning and painting. This not only resulted in customer delight, but also enabled our clients to procure quality products from a single supplier, opening new avenues for Company’s unique offerings.

Stator frame with core ready for winding

Earlier, the supply chain for stator core involved routing parts through multiple locations for casting, machining and shrink fit, before its delivery to Mexico for motor manufacturing. The lengthy process affected the quality of products, the time for procurement and it also had an impact on cost. The Company revisited its value chain to procure stator frame casting, built in-house capability for pre machining, shrink fitting stator core within the frame and final machining. This eliminated quality and delivery issues for the end customer and provided a significant cost advantage. Coordinate measuring machine (CMM) inspection was also integrated with the production process to ensure the quality of finished products. The cumulative effect of these interventions resulted in superior customer experience, horizontal deployment of similar model to other products and improvement of the Company’s business prospects.
