DAK Material Testing Systems in Industry & Research

DAK testing machines have been used extensively for ISRO’s Chandrayaan-3 mission and Gaganyaan programme. We are proud to support the engineering behind India’s space ambitions with material testing systems designed and manufactured in India.

Across ISRO applications, testing includes solid-propellant tensile strength and elongation, spring stiffness, bearing strength and O-ring evaluation. Materials are also assessed at −150 °C to simulate low-temperature space conditions and at +400 °C for high-temperature testing, helping engineers understand their behaviour under demanding conditions.

DAK has supplied multiple material testing machines to Hindustan Aeronautics Limited (HAL) for testing associated with the LCA Tejas programme and other aircraft-manufacturing activities.

Behind an aircraft is a broad programme of engineering and material evaluation. DAK contributes through the testing systems used in this work, supporting HAL’s material-testing capability as it advances India’s indigenous aviation programmes.

DAK universal testing machines support BrahMos Aerospace in testing materials and internal missile components, including metals, springs and rubber seals.

Metal tensile tests examine strength and deformation. Spring testing measures stiffness, while rubber testing evaluates tensile strength and elongation. Together, these capabilities support the assessment of the different material behaviours within a demanding defence-engineering programme.

DAK universal testing machines support DRDO's evaluation of metals, FRP composites, rubber materials and O-rings for defence applications, including missile components and tank-armour materials.

The applications also include tensile and elongation testing of insulating materials for personnel operating at high altitudes and in below-freezing conditions. Across these varied materials, the testing helps characterise their mechanical response—connecting laboratory measurements with the material questions engineers need to investigate.

Pidilite, Anabond and Normet use DAK testing systems to evaluate adhesion, bond strength and tensile behaviour—measuring how adhesives and bonded materials hold together, deform and respond to load.

Across these applications, testing includes adhesive and tile-bond strength, pull-off adhesion, slant shear, crack bridging and coating deformation. Using fixtures suited to each specimen and test method, these measurements help development and quality teams compare formulations and assess how bonded interfaces and coatings respond to mechanical loading.

DAK serves tyre manufacturers including BKT, MRF, CEAT and Emerald Tyres. Across these customer relationships, our UTM, MDR and RPA systems support testing from rubber compound studies to the mechanical evaluation of tyre-related components.

Applications include tensile and elongation testing of rubber dumbbells, compression, puncture, tyre-valve pull-out, curing studies and rubber process analysis. Together, these areas connect the study of rubber behaviour with measurements of strength, deformation and component response.

ICAT and ARAI, automotive testing and certification organisations in India, use DAK machines for a wide variety of tensile, compression, flexural and shear tests. These measurements help their laboratories evaluate the mechanical behaviour of automotive materials and components.

Autoliv uses DAK machines for seat-belt tensile testing and seat-belt buckle strength testing. By examining the webbing and buckle through their respective loading arrangements, these tests provide mechanical measurements for the evaluation of occupant-restraint components.

NIPER uses DAK universal testing equipment across a wide range of medical and biomedical investigations. Applications include syringe plunger testing—break-loose, glide and pull-out forces—alongside needle pull-out testing, needle penetration and penetration through vial closures.

These tests examine different aspects of a device's mechanical behaviour: the force needed to operate a syringe, the integrity of an assembled needle, and the resistance encountered during penetration. They form part of a broader programme of biomedical testing, with specimen-specific fixtures bringing different research questions onto the testing platform.

DAK machines support research across IITs, NITs and CSIR laboratories. At IITs, applications include rubber development and the study of metal alloys; NITs use our systems for metals and alloy investigations, while CSIR laboratories use them in instrumentation and research.

One IIT application combines tensile loading and twisting of animal tissue in a bio-bath on a UTM. This work investigates how combined loading affects tissue, helping researchers study injury mechanisms and inform the development of protective equipment. Together, these applications illustrate the range of questions that carefully configured mechanical testing can help researchers explore.
