Pre cut Shim Supplier & Exporter in India
Ask any maintenance engineer who’s had to re-align a pump at 2 a.m. and they’ll tell you the same thing: hand-cutting shim stock on site is nobody’s idea of a good time. That’s the gap Kalpataru Piping Solution set out to close. We’re a Mumbai-based pre cut shim supplier and exporter, and our shims come out of the factory ready to drop straight into place — no burrs, no on-site marking, no trial and error. Each piece is stamped with its exact thickness, held to a tight cutting tolerance, and available in whatever metallurgy the job calls for, from everyday Stainless Steel 304 and 316 to brass and copper for electrical work, right up to Monel, Inconel, Hastelloy and Titanium for the applications where nothing less will do. Need one alignment shim for a single pump base, or a full export container of shim kits for a shutdown crew halfway across the world? Either way, the same laser-cutting lines and inspection process stand behind it. Below you’ll find the specifications, sizes, materials, applications and pricing pointers you actually need to spec the right shim — written for engineers and buyers who’d rather skip the sales fluff and get to the numbers.

What is pre cut shim?
Think of a pre cut shim as the opposite of shim stock. Stock comes to you as a coil or a flat sheet, and someone on your team has to measure, mark and cut it before it’s usable — which is fine until you’re doing it for the fifth time that week. A pre cut shim skips all of that: it’s already the right thickness, already the right shape, and it goes straight into the gap. We make ours in slotted, horseshoe, square, rectangular, round and fully custom profiles, choosing between CNC laser cutting, stamping, waterjet or EDM depending on what the material and tolerance demand.

Manufacturing Process & Quality Control
- Material Sourcing & Verification — Raw coil and sheet stock is sourced from approved mills (Jindal, Posco, Aperam, Acerinox and others) with full mill test certification and traceability.
- Precision Cutting — Shims are cut using CNC laser cutting for clean, burr-free edges up to 6 mm thickness, or stamping, waterjet and EDM for special alloys, heat-sensitive materials and ultra-tight tolerances.
- Marking & Deburring — Every shim is thickness-marked and deburred so it is safe to handle and simple to identify during re-shimming.
- Dimensional & Quality Inspection — 100% dimensional and flatness inspection, supported by chemical composition verification and radiographic testing where specified.
- Packing & Documentation — Shims are packed in shim-corral cases, cartons or export crates along with mill certificates (EN 10204/3.1B) and, where required, third-party inspection reports.
- Global Dispatch — Orders are dispatched to customers across the Middle East, Asia, Africa, Europe and the Americas through our established logistics network
