India’s regulatory regime for automotive aluminum die-cast parts is shaped by MoRTH notifications under the Central Motor Vehicles Rules (CMVR), supported by the Automotive Industry Standards Committee (AISC) and Automotive Industry Standards (AIS) published through ARAI, alongside product and material standardization by the Bureau of Indian Standards (BIS). In practice, these frameworks affect casting validation, documentation, and the test evidence OEMs request for safety and homologation, particularly for structural components.

A key compliance anchor for foundries and their upstream suppliers is BIS material standard IS 617:2024 for aluminium and aluminium alloy ingots and castings (applicable across casting processes including pressure die casting), which sets chemical composition and mechanical test parameters. In addition, DPIIT’s Aluminium and Aluminium Alloy Products (Quality Control) Order, 2026 (S.O. 1319(E), dated 11 March 2026) mandates BIS certification for specified aluminium and aluminium alloy products under the BIS Act, 2016, with BIS as the enforcing authority. Implementation is staged, with requirements becoming effective from 1 December 2026 for covered product groups, which increases the need for lot-level traceability and formal compliance documentation across the supply chain.

Value Chain Analysis

The value chain starts with primary aluminum and secondary scrap sourcing, followed by alloying and melt preparation, die and tooling design (often involving simulation-led gating and solidification engineering), and core manufacturing through high-pressure die casting (and, where relevant, low-pressure and gravity routes). Downstream steps include trimming, heat treatment (where specified), CNC machining, surface finishing, dimensional and metallurgical inspection, and then delivery to OEM/Tier-1 assembly lines under just-in-sequence schedules, with exports routed through coastal logistics corridors.

Industry participants include integrated automotive component suppliers and specialist casters. Named players with aluminum die-casting footprints include Endurance Technologies, Rockman Industries, Jaya Hind Industries, Sipra Engineers, Sandhar Group, Spark Minda Group, and Rico Auto Industries, supported by multi-location manufacturing networks serving regional automotive clusters.
