From first prototype to production run — Stratnel offers manufacturing services built around 3D printing and casting technologies, with engineering support at every stage. All under one roof, all ISO 9001:2015 certified.
We manufacture 3D printed polymer parts for every stage of the product lifecycle — from early design validation through to production-grade end-use components. Using FDM, SLS, and SLA technologies, we work with engineers to ensure parts are optimised for printing and perform exactly as required.

Convert your CAD into a physical prototype before committing to tooling. Catch design errors early, compare iterations side by side, and de-risk your product launch — all with engineering input from our team on how to improve your design for manufacturing.

Custom jigs, fixtures, templates, and assembly tools printed on-demand for your shop floor. Improve repeatability, reduce operator error, and get purpose-built production tooling in a fraction of the time and cost of traditional fabrication.

Structural polymer components manufactured to production tolerances for direct use in your product or assembly. From one-off parts to low-volume production runs, we maintain consistent quality across every batch with full inspection reports shipped with every order.
Stratnel has been a trusted supplier of 3D printed investment casting patterns to leading foundries across India for over eight years. Our patterns consistently deliver near-zero ash content, excellent surface finish, and tight dimensional control — enabling foundries to serve customers who need low volumes or complex geometries without committing to hard tooling.
3D printed wax-replacement patterns manufactured using Stratment 102 — our proprietary FDM filament developed specifically for investment casting. Our patterns deliver the surface quality, dimensional accuracy, and clean burnout that foundries depend on for critical castings in aerospace, defence, and medical applications.
Eliminate hard tooling costs for sand casting. Our 3D printed patterns let you produce complex metal parts in small volumes without the lead time of traditional pattern making.
Vacuum casting produces high-quality polyurethane parts using silicone moulds made from a 3D printed master pattern. Ideal for small production runs of 10–50 parts where injection moulding tooling is not yet justified — delivering surface finish and material properties close to production-grade moulded parts, at a fraction of the cost and lead time.

We offer four grades of vacuum cast polyurethane to cover the full range of application requirements — from rigid structural housings to soft flexible components, optically clear covers, and glass-filled high-strength parts.
Durable, dimensionally stable parts for housings, enclosures, and structural components. Good impact resistance and surface finish.
Flexible polyurethane for seals, grips, gaskets, over-moulded handles, and vibration-damping components. Shore hardness to specification.
Optically transparent polyurethane for lenses, light covers, and display windows. Can be tinted. High surface quality finish.
Glass-filled grade for higher stiffness, strength, and dimensional stability. For structural brackets and load-bearing components.
Our process is designed to be fast, transparent, and low-effort for you.
