We do not ask how it
has always been done.

We ask what science demands, and how to engineer it with uncompromising precision. These are the laws our shop floor is run by.

  1. Truth above all

    Reality is our highest authority. We never alter data. We never hide defects. We never tell a customer what they want to hear. We tell them what is true.

  2. Physics always wins

    Steel does not care about budgets. Pressure does not care about deadlines. If physics disagrees with us, we change. Physics never does.

  3. Precision is respect

    Precision is respect for science, for customers, for colleagues. Every micron ignored today becomes someone's problem tomorrow. We refuse to create that future.

  4. Every defect is a gift

    A defect ignored becomes a future accident. A defect understood becomes permanent knowledge. So we investigate every one of them, without blame.

  5. Simplicity is mastery

    If two solutions perform equally, the simpler one wins, not because simplicity is fashionable, but because it is more reliable. Less variation. Less failure.

  6. Build for a century

    We never optimise for this quarter. Every decision must survive one question: will this still be right a hundred years from now?

Quality is the degree to which
reality matches intent.

If a drawing specifies 25.000 mm, quality is not 24.98. And it is not 25.03. Inspection does not create quality — it only verifies it.

Welding is the discipline
we are known for.

A pressure vessel is only as strong as its weakest joint. So welding here is not a shop-floor activity. It is a documented engineering process, governed by qualified procedures, qualified people and verified results.

  • GMAWMetal inert / active gas — MIG · MAG
  • SAWSubmerged arc, long girth seams
  • SMAWManual metal arc — MMAW
  • RWResistance & projection welding

WHAT THE ACCREDITATION MEANS

ISO 3834

Quality requirements for fusion welding of metallic materials. It governs how every weld is planned, controlled, inspected and recorded, not just how it looks.

EN 15085

Welding of railway vehicles and components. The standard that qualifies a shop to weld safety-critical rolling-stock assemblies.

HOW EVERY JOINT IS VERIFIED

  • Qualified welding procedures — WPS & PQR
  • Welder qualification records, kept current
  • Visual inspection of every weld
  • Dimensional inspection against drawing
  • Leak and pressure testing of vessels
  • Material and weld traceability, documented

“Our customers do not buy steel. They buy confidence.”

Built to hold pressure.
And to keep holding it.

Water tanks, air reservoirs, dryers and installation assemblies: rolled, formed, welded and tested in-house. From a single uncoated stainless vessel to twin tanks carried on their own welded frames, and complete air suspension systems for buses, trucks, trailers and rail.

Pass the caliper across any part below and the photograph gives way to its radiograph.

Twin water tank assembly on a single welded frame, with dished ends and flanged access ports
WT-2 / TWIN WATER TANKS

Twin water tanks

Two tanks carried on a single welded frame, with dished ends, flanged access ports and integral mounting feet. Rolled, welded and leak-tested as one assembly rather than two parts bolted together.

Twenty litres, stainless, and deliberately left uncoated, because on this vessel the weld is the finish. Nothing is filled, painted or hidden. What you see is what came off the bench.

A dash means we have not published that figure yet, not that it does not exist. Ask and we will send the drawing and the test record for the exact build you need.

Most of what we build
does not have a catalogue page.

A large part of what leaves this plant was designed for one customer and exists nowhere else. Send us a drawing, a specification, or just the problem, and we will design, develop and build to it.

From flat sheet
to sealed vessel.

The whole route runs under one roof at Faridabad, which is how tolerance survives from the cutting bed all the way to despatch. Laser cutting, plate rolling and dished ends, and press brake forming.

STAGE 01 CNC laser cutting

Profiles cut to drawing, with the edge quality that determines every joint downstream.

STAGE 02 Press brake forming

Bends set, checked and re-checked before a part is ever allowed to reach the weld bay.

STAGE 03 Plate rolling

Flat plate becomes a shell. Roundness here decides whether the girth seam closes cleanly.

STAGE 04 Certified welding

Qualified procedures, qualified welders, recorded results. And, where the joint repeats, a purpose-built machine running the seam so it comes out identical every time.

Organised component stores with labelled racking and floor marking
STAGE 05 Controlled stores

Labelled racking, marked floors, recorded movement. Excellence is invisible. It lives in preparation long before a customer sees a result.

BEFORE YOU ASK ANYBODY FOR A PRICE Put your drawing
on the light box. Drop a DXF and read its overall size, cut length, pierce count and weight in your own material and thickness. A PDF drawing goes up on the light box too, though only a DXF can be measured. Read by your own browser — the file is never uploaded, and closing the tab is the end of it. Read a drawing →

    You send a drawing

    Or a problem. Either works. If the drawing is ambiguous we say so before we quote, not after we have built it.

    WHAT YOU GET · A written reading of your drawing, with the questions it raises

Leadership at Sakshi Tools reviewing drawings

Twenty-eight years of
doing it properly.

Founded in 1998 by Brahma Parkash Arya, Sakshi Tools has spent nearly three decades manufacturing to other people's drawings, and holding itself to a standard higher than the drawing asked for.

Our team is made up of experienced, dedicated professionals who care about the work. Great engineering is not an act of genius; it is the accumulation of thousands of correct decisions, made with discipline, by people who would rather be right than quick.

Engineering team reviewing a job together at Sakshi Tools

MISSION Deliver a comprehensive range of industrial solutions — precision-engineered machines, testing equipment and air reservoirs — driven by expert technical support and a relentless focus on total customer satisfaction.

Send us the drawing.
We'll tell you the truth.

Whether it is a single vessel or a full assembly — tell us what it has to withstand, and we will tell you exactly how we would build it.

WHAT WE NEED TO QUOTE YOU

  1. A drawing, or a sketchA hand sketch with dimensions is enough to start. We will tell you what is missing.
  2. Capacity and working pressureThe two numbers that decide plate thickness, head form and test regime.
  3. Material and finishStainless, coated, or left bare. Say if the weld has to stay visible.
  4. Quantity, and whether it repeatsA one-off and a monthly schedule are different jobs. Both are welcome.
  5. Standards it must satisfyAnd who inspects — you, your customer, or a third party.
  6. How it mounts and gets handledBrackets, feet, lifting points. Most late changes come from this.
  7. When you need the first oneNot the whole order — the first piece you can put in front of someone.

Have only some of it? Send what you have. A short conversation usually settles the rest faster than a form does.

YOUR BUILD REQUIREMENTS

Drop a DXF and it goes up on the light box before you send: drawn to scale, measured, cut length and pierces counted, weight worked out. A PDF drawing is shown the same way, but a PDF carries no scale, so it is not measured.

Drawings you send are treated as confidential, are not shared outside this works, and are deleted on request. NDA on request. We will sign yours. What we do with your details →
