NESTech is a leading provider of Casting Simulation Services and an Authorized Master Software Distributor in India for C3P Cast-Designer Software. We help foundries and manufacturing companies optimize their casting processes, eliminate defects, reduce scrap, improve yield, and extend die life through advanced computer-aided engineering (CAE) simulation.

Our casting simulation expertise spans across all major casting processes including High Pressure Die Casting (HPDC), Sand Casting, Gravity Die Casting (Permanent Mold), and Investment Casting (Lost Wax). We work with a wide range of alloys including Aluminum (ADC12, A380, A356, LM6, LM25), Magnesium (AZ91D, AM60B), Zinc (Zamak 3, Zamak 5), Copper alloys, Grey Cast Iron, Ductile Cast Iron (SGI/Nodular Iron), and Steel (Carbon, Alloy, Stainless).

Using C3P Cast-Designer – a powerful and intuitive casting simulation platform – we provide end-to-end casting engineering solutions from gating and feeder design to defect prediction, process parameter optimization, and die thermal management. Whether you are developing a new casting or troubleshooting an existing production line, our simulation services help you achieve right-first-time casting, reducing costly physical trials and accelerating time to market.
