India's vacuum furnace industry has grown rapidly over the past decade, driven by expansion in aerospace, defence, automotive, and advanced manufacturing sectors. Yet reliable supply of high-quality graphite insulation boards has remained a challenge for many plant managers — with long lead times from European suppliers and quality inconsistency from unbranded domestic sources.
Expo Advanced Materials Private Limited is a TOYO TANSO authorised partner, ISO 9001:2015 certified, and one of India's most trusted manufacturers and suppliers of graphite insulation boards and vacuum furnace components.
Why India-Based Sourcing Matters
- Lead time: Domestic supply means 5–10 business days vs 8–12 weeks from Europe or Japan.
- Cost: Sourcing locally eliminates import duties that can add 25–35% to the delivered price of European boards.
- Support: Direct technical support in your time zone, in English or Hindi.
- Trial orders: Smaller minimum order quantities for evaluation before committing to a large purchase.
Our Manufacturing Capability
- Rigid graphite felt boards — standard industrial grades, bulk density 0.18–0.32 g/cm³, up to 2200 °C.
- Soft graphite felt sheets — standard and high-purity grades for low-temperature zones and backing layers.
- CFC insulation boards — carbon fibre composite panels for high-cycle, high-temperature, or clean-process applications.
All boards are CNC-machined to your dimensions with tolerances to ±0.5 mm, supplied with full dimensional inspection reports and material test certificates.
