The Coimbatore works: how plain, thread, and API gauges are made, heat-treated, and calibrated, with ISO 9001, NABL, and API 5B / 7-2 licences.
Precision gauge manufacturing built on engineering depth, integrated production, and traceable quality, from a single Coimbatore works.
DSN Enterprises manufactures precision plain, thread, and API gauges for Indian industry. Every gauge is built to customer drawing, calibrated to traceable standards, and shipped with complete certification, no shortcuts.
Integrated manufacturing means fewer hand-offs between production, inspection, and documentation, resulting in tighter tolerances and shorter lead times.
From our Coimbatore works, we combine CNC machining, precision grinding, and controlled heat treatment with a NABL-aligned calibration laboratory. One team responsible from raw material to final certificate.
We supply plants across Tamil Nadu, Bangalore, and Hyderabad, national OEM and job-shop networks, and export customers who demand the same rigour on every shipment.
Every gauge is made to agreed tolerances, inspected, and documented. What we ship matches what your line accepts, no variance.
Continuous investment in tooling, process control, and application know-how for demanding thread forms and custom profiles.
Clear lead times from enquiry to dispatch. Gauges that fit your quality plan and delivery schedule, not generic catalogue lead times.
We stand behind every measurement and certificate. If a gauge isn't fit for use, we flag it before it reaches your floor.
Manufacturing depth, accredited calibration, and engineers who speak your drawing language.
CNC machining, grinding, and lapping under one roof, built for repeatable tolerances on plain and thread gauges, with NABL-aligned calibration in-house.
Gauge designers and metrologists who review drawings, thread data, and feasibility before production starts. Your print is understood before steel is cut.
Strong coverage of Tamil Nadu from Coimbatore, plus scheduled dispatch into Bangalore and Hyderabad, with pan-India supply and export programmes for OCTG, automotive, aerospace, and precision engineering.
ISO 9001:2015 quality management, NABL-accredited calibration, and API 5B / 7-2 licensing for licensed OCTG gauging where your programme requires it.
Controlled steps from material to certificate, every gauge leaves our works ready for production use.
OHNS (W) and carbide are selected against wear, size, and tolerance class, mill certificates recorded for critical programmes.
CNC turning, grinding, and lapping hold size and form through every pass, critical for thread and plain gauge function.
Final inspection, hardness check, and calibration against traceable masters, documented on the certificate you file with QA.
Accreditations that underpin your audits, customer approvals, and OCTG programmes.
Licensed manufacturing for API 5B thread gauging, used on casing, tubing, and line pipe connections across oil and gas supply chains.
NABL-accredited calibration laboratory delivering traceable results accepted in ISO audits and customer source inspections.
API 7-2 licensing for rotary shouldered connection gauges, used on drill string and heavy-duty threading programmes.
Quality management system covering design, manufacture, calibration, and customer feedback loops, audited and certified.
Send your drawing or gauge list, we will confirm scope, lead time, and certificate requirements from Coimbatore.
