6 facilities. 43 presses. 20,000+ parts a day.
Plant network
Natraj Moulds operates 6 specialised manufacturing units in Nashik, Maharashtra, designed for clean material flow and optimised cycle times — housing moulding, secondary handling, storage and dispatch under one operational model.
ERP-networked operations
All 6 facilities are networked via our custom ERP system, managing inventory replenishment, machine scheduling, shift output and dispatch tracking in real time.
Built for trust, precision, and responsible progress.
Corporate vision
To be the most trusted global partner in precision thermoset moulding — driven by technical excellence, zero-defect quality, sustainable manufacturing, and continuous innovation for critical industrial applications.
Mission statement
Four commitments guide how we serve partners, operate our facilities, protect the environment, and develop our people.
For manufacturing excellence
Maintain continuous operational control across our 6 facilities using custom ERP systems, process discipline, and rigorous EN ISO 9001:2015 quality standards.
For our environment
Lead responsible thermoset processing through solar energy, Scope 1 and 2 tracking, and Product Carbon Footprint transparency to support global decarbonisation.
For our people
Foster a safety-first, growth-oriented workplace for our employees through technical training and operational empowerment.
Core values
Engineering precision
Optimising SMC, DMC, and Phenolic materials to meet exact thermal, mechanical, and dielectric parameters.
Uncompromising quality
Embedding quality from incoming compound verification through cycle control and final inspection for zero-defect delivery.
Customer partnership
Building long-term supply relationships through transparency, stock compliance, and consistent OTIF execution.
Responsible manufacturing
Reducing environmental impact through renewable energy, waste management, and carbon footprint measurement.
Moulding and secondary processes, engineered for repeatability.
Compression moulding
Our primary method for medium-to-large, high-strength thermoset components. Pre-measured compound is placed into heated mould cavities under high pressure.
- Superior mechanical strength and structural uniformity
- Low internal stress, high resistance to warping
- Efficient processing of heavy-section SMC and DMC parts
Transfer moulding
For parts demanding intricate geometries, thin wall sections or tight dimensional tolerances, with exact material placement into closed cavities.
- Precise metering of compound into closed mould cavities
- Reduced flash and minimal post-mould finishing
- Excellent repeatability for high-density electrical parts
Secondary & sub-assembly
Complete component solutions, ready for the customer's production line — no additional finishing required on receipt.
- Deflashing, trimming and surface grinding
- Post-mould drilling, tapping and machining
- Mechanical assembly of hardware, pins and fasteners
