Introduction
SISMA S.p.A. is an Italian precision engineering company founded in 1961, with over six decades of specialisation in laser technology for the jewellery industry. Their systems are used by jewellery manufacturers, goldsmiths, and production facilities worldwide for laser welding, marking, micro-cutting, chain manufacturing, and metal additive manufacturing.
SISMA’s range covers the full spectrum of laser applications in modern jewellery manufacturing — from a single-bench welder for a goldsmith workshop to an industrial 3D metal printing machine for a design studio. Every system is built to the Italian engineering standard that has made SISMA one of the most trusted names in jewellery laser technology globally.
NJTPL has been the authorised Indian dealer for SISMA since 2002 — giving Indian manufacturers direct access to genuine equipment, backed by local installation, operator training, and after-sales service from Mumbai.

Why Laser Technology Is Essential in Jewellery Manufacturing
Laser technology addresses precision, speed, and consistency demands that manual processes cannot deliver at scale — across multiple stages of the production process. Laser welding replaces the torch with none of the heat damage risk to stones or settings. Laser marking eliminates hand engraving variability on production volumes. Laser cutting enables micro-precision work no mechanical tool can replicate. Additive manufacturing opens design possibilities casting simply cannot achieve.
Across all applications, SISMA systems deliver pinpoint precision, non-contact processing with no workpiece distortion, a minimal heat-affected zone that protects surrounding metal and stones, and fully repeatable programmable results — the same parameter set, the same result, every time.






Product Range
LMD Ready | LMD | LM
LMD Ready
LMD Ready is SISMA’s entry-level welder — pre-configured for goldsmiths and workshops new to laser welding. It handles ring resizing, prong tipping, chain repair, and clasp welding reliably. The right starting point for a workshop moving from torch to laser for the first time.
LMD
LMD is the full-featured professional range — available in multiple power outputs for different metals and section thicknesses. It incorporates Smart Spot beam-shaping technology, ECO mode, and remote connectivity. Better suited to production environments requiring higher power, consistency, and uptime — including platinum welding and heavier fabrication.
LM
LM is SISMA’s compact bench welder — suited to fine jewellery repair, stone-in-place welding, and delicate fabrication where a small footprint and precise energy control are the priority.
Easy | Easy Go | Big Smark | Big Smarky
Easy
Easy is SISMA’s compact marking system for hallmarking, logo engraving, serial number marking, and surface decoration — a practical, space-efficient solution for workshops needing consistent laser marking.
Easy Go
Easy Go is the portable version — a transportable unit for manufacturers needing marking capability across multiple locations or on larger workpieces that cannot be brought to a fixed station.
Big Smark
Big Smark is the larger-format marking system for higher production volumes, larger workpieces, and more demanding engraving applications where the Easy’s working area is insufficient.
Big Smarky
Big Smarky combines laser marking with precision micro-cutting — enabling precise cutting of sheet metal, filigree patterns, and fine geometric forms alongside full marking capability.
MySint 100
The MySint 100 is SISMA’s selective laser melting metal 3D printer — producing complex precious metal forms directly from digital files, without tooling or casting. Gold and palladium alloy powders are fused layer by layer, building forms with internal geometries and structural complexity that casting cannot achieve. Suited to design studios, export manufacturers, and larger facilities needing complex 3D forms or rapid design prototyping.
Bismark
The Bismark is SISMA’s dedicated laser chain coupling machine for automated welding of Bismarck chain links. Manual chain coupling is slow and inconsistent. The Bismark automates the process — laser-welding each link closure with consistent precision at production throughput speeds, link after link.

Frequently Asked Questions
LMD Ready vs. LMD — which is right for my workshop?
The LMD Ready suits workshops new to laser welding focused on standard repair tasks. The full LMD range is better for production environments needing higher power, Smart Spot technology, and remote connectivity. NJTPL can advise based on your application.
Easy, Big Smark, or Big Smarky — when do I need cutting?
Easy and Easy Go are marking and engraving systems. Big Smark extends this to larger formats and volumes. Big Smarky adds micro-cutting — the correct choice if cutting filigree or sheet metal forms is a production requirement.
Is the MySint 100 right for a smaller manufacturer?
The MySint 100 is an industrial machine suited to design studios, export houses, or larger manufacturers needing complex 3D forms or design prototyping. NJTPL will assess your requirements honestly before recommending it.
What metals do SISMA laser welders work with?
All standard jewellery metals — yellow, white, and rose gold across all carats, sterling silver, platinum, and palladium alloys. Wattage and pulse parameters are configured by NJTPL during commissioning.
