PROCESS & CRAFTSMANSHIP
Every Oystra commission follows a defined process — from first brief to installed object. Our production capability is entirely in-house. From the first prototype on our 3D printer to the final polish on a vacuum-cast bronze panel, every stage is controlled, documented, and accountable.
PROCESS & CRAFTSMANSHIP
The Brief
Every commission begins with a conversation. We receive project drawings, mood references, finish preferences, and programme requirements. From this we produce a written design intent document and a preliminary materials schedule — the first shared language between studio and craftsman
Design, Drawing & Prototyping
Our studio team produces dimensional drawings to 1:1 scale for all architectural elements. Drawings are issued in DWG and PDF format for integration into project documentation. Where form requires resolution before drawing sign-off, we use our in-house 3D printer to produce a physical prototype — a rapid, accurate model of the finished object before a single gram of metal is committed.
Material Sampling
Before production commences, we produce finish samples on the specified substrate — a section of CNC-cut brass panel, a powder-coated iron tile, a vacuum-cast bronze piece, a Corian surface with inlay test. Samples are dispatched to site or studio and signed off before production begins. This stage is not optional.
Making
Production takes place entirely in our Delhi NCR facility. Sand-casting and vacuum casting are conducted in-house using our manual and electric furnaces, reducing reliance on external suppliers and ensuring every casting meets our quality standard before it enters the finishing line.
CNC laser cutting handles precision flat work in brass, bronze, and aluminium — intricate jali patterns, dimensionally accurate panel profiles, and complex geometric cuts that would be impossible to achieve by hand at scale. The CNC wooden machine supports any timber-backed hybrid work.
Shot blasting prepares all metal surfaces for coating adhesion. Our powder coating oven and spray booths provide consistent, durable finishes across large production batches. Liquid paint finishing adds flexibility for bespoke colour matching and custom applications. Our spinning machine produces all cylindrical and vessel forms — planters, lamp bodies, rounded furniture elements.
The surface is always hand-finished. MIG welding handles all structural assembly. The result is an object that has been through industrial precision and human touch in equal measure.
Quality & Inspection
Every piece is checked against the approved sample and original drawing before despatch. Dimensional tolerances, surface finish quality, and structural integrity are documented. A material passport recording the techniques used and finish specification is issued with every commission
Delivery & Installation
We manage crating, transport, and site delivery in coordination with your project team. For large architectural elements, we attend site for installation supervision and final touch-up. Maintenance and aftercare guidance is supplied for all surface finishes.
The Techniques
Advanced brass fabrication techniques · precision CNC cutting · laser etching and chemical embossing for intricate detailing
Handcrafted metal forming · casting, forging and polishing · PVD coating and finishing for long-lasting architectural-grade surfaces
Sand-Casting
Molten brass or bronze is poured into sand molds built from our patterns using our in-house manual and electric furnaces. The resulting surface carries the texture of the sand — organic, warm, and unrepeatable. Sections are cleaned, chased, and hand-finished before assembly.
Vacuum Casting
Our vacuum casting facility produces defect-free, high-density cast components — ideal for decorative elements requiring exceptional surface quality and dimensional accuracy. Vacuum casting eliminates the air pockets and inclusions common in open casting, producing work of jewellery-grade precision at furniture and architectural scale.
CNC Laser Cutting
Our CNC metal sheet laser cutter enables precision cutting of brass and aluminium sheet to tolerances impossible to achieve by hand. Intricate jali screens, geometric panel systems, and complex profile work are cut with complete accuracy and speed, then hand-finished and patinated.
Repoussé & Chasing
Sheet brass or bronze is worked from behind with hammers and punches to raise dimensional relief forms — botanical motifs, geometric patterns, figurative elements. The surface is then chased from the front to refine detail. A technique unchanged in three thousand years, now produced alongside CNC precision.
Chemical Patination
Brass and bronze surfaces are treated with chemical solutions — liver of sulphur, ferric nitrate, cupric nitrate — to produce controlled colour change: deep oxidised black, blue-green verdigris, warm amber. Each patina is applied by hand and sealed with wax or lacquer to specification.
Powder Coating & Liquid Finishing
Our in-house powder coating oven and liquid paint booth deliver durable, consistent finishes on cast iron, aluminium, and fabricated brass elements. Powder coating provides corrosion-resistant, globally compliant finishes. Liquid finishing extends the palette to bespoke matched colours for project-specific requirements.
Metal Spinning
Our spinning machine shapes brass and aluminium sheet into precise cylindrical and curved forms — lamp bodies, vessel sculptures, planters, and rounded furniture components. Spun forms carry a characteristic directional grain that is distinctly different from cast or fabricated surfaces.
Shot Blasting
All metal components destined for coating pass through our shot blasting system, which uniformly prepares the surface for maximum adhesion — the difference between a finish that lasts decades and one that does not.
Corian Fabrication
Corian solid surface is CNC-machined, thermoformed, and hand-finished within our facility. As a substrate for metal inlay, CNC-engraved devotional work, and backlit architectural panels, Corian provides a clean, seamless surface that integrates with brass and bronze elements with precision and permanence.
Submit Your Brief. We'll Build the Specification.
Every Oystra commission begins with a formal design brief — not a catalogue selection. We review your project parameters, material requirements, and site constraints before preparing a specification response. Our team operates in the technical language of architectural and interior design practice.
Whether you are specifying a single architectural component or coordinating a complete interior material package across brass, glass, and solid surface, Oystra’s submission process is structured to your programme and procurement timeline.
