Infrastructure

The Automotive and Industrial Division of HTL Ltd operates from two locations in Chennai and Hosur, covering an area of 20,000 sq. ft. and 10,000 sq. ft. respectively. These facilities are well-equipped with modern machinery and systems to carry out key processes including auto wire cutting, crimping, cable processing, stripping, ultrasonic welding, and other assembly operations. These processes enable the division to manufacture high-quality wiring harnesses and automotive components. Both facilities have obtained industry-recognized certifications such as IATF 16949, ISO 9001, 14001, and 45001 standards. The division has testing labs that conform to ISO 6722-1 standards, ensuring that the products meet or exceed customer expectations.

Since its establishment in 2019, the Automotive and Industrial division has been following the "Design to Delivery" concept. The division has skilled engineering teams and the necessary CAD, harness design, and development software solutions to design and develop wire harnesses in-house. This approach allows for the verification of the wire harness assembly before starting the assembly process, which reduces late engineering changes.

The company also emphasizes regular process improvement tools and techniques such as Lean manufacturing, SMED, Poka-Yoke principles, and monthly kaizen initiative that help in identifying and eliminating waste to deliver products with the highest possible quality.
