Sigma Advanced Systems starts aerospace production at Sri City
Sigma Advanced Systems has started making airplane parts at a new factory in Sri City, India.
The factory began production only eight months after construction started.
Its first parts were sent to the company’s UK operations for checking.
The facility currently has enough equipment for 100,000 machine-hours of work each year.
It may eventually grow to nearly 300,000 machine-hours per year.
Sigma wants to move more of its airplane-parts manufacturing to India.
After expansion, about 70% of the manufacturing process is expected to happen there.
The company also plans to train workers in specialised aerospace skills.
Sigma Advanced Systems has begun producing precision-machined aerospace components at its Sri City facility in Andhra Pradesh.
The facility moved from construction to active production in eight months, and its first batch was sent to the company’s UK operations for final verification.
The 75,000-square-foot facility currently supports 100,000 machining hours annually and is designed to scale up to nearly 300,000 hours.
Sigma expects about 70% of its aerospace manufacturing process to be carried out in India after the planned expansion.
The facility has completed initial source-change approval stages with Rolls-Royce Aerospace and plans to provide specialised on-campus training.
