Turning ideas into technical models.

Rhino & Fusion 360 files prepared for tooling, mold feasibility, and production accuracy.

Precision molds built in-house.

CNC milling for steel tooling, cavities, and inserts prepared for die-casting performance.

Tooling prepared for production.

Molds aligned, tested, and optimized to guarantee clean filling and repeatable results.

High-volume die casting for consistent output.

Industry 4.0 automated machines for stable production and dimensional repeatability.

From casting to clean components.

Excess material removed, parts separated, and prepared for finishing stages.

High-volume delivery capability.

Thousands of identical components are produced per cycle to meet industrial supply needs.

Smerigliatura & burattatura.

Hand refinement and tumbling polishing to smooth surfaces and remove casting lines.

Frames, buckles, rings & custom hardware.

Every piece is engineered for galvanic treatment and can be finished in any colour or effect available, matching brand identity, material requirements, and design specifications.

2–3 week typical lead time.

Orders are packed, palletised, and shipped worldwide through reliable logistics partners.

Turning concepts into zamak hardware with centrifugal die casting — perfect for testing, sampling, and low-order quantities.

Quick Casting. Quick Validation. Quick Decisions.

CAD Design & Pre-Production Setup

Bringing concepts to life with Rhino/Fusion 360. Models are prepared for mold geometry, shrinkage, and casting flow.

Mold Preparation for Centrifugal Casting

Brass, Zamak or Silicone masterpiece samples are installed, aligned and heated for consistent filling and material flow.

Spinning Cast Cycle

The mold spins at a controlled speed to distribute molten zamak equally — ideal for prototypes and low-volume batches.

Centrifugal Casting Machine Operation

Molten zamak is poured and pressed outward by rotation, ensuring detailed parts and crisp edges.

Part Extraction & Manual Refining

Pieces are removed from the mold and sprues are separated for first-stage cleanup before finishing.

Raw Output Before Finishing

Unfinished zamak components ready for tumbling, sanding, or custom finishing based on client specifications.

Sample Sets & Prototype Series

Small quantity runs for testing, sizing, functionality, or approval before mass production.

Delivery in 2–3 Weeks

Fast lead times for prototypes and low-volume production. Worldwide shipping available.

Organic Shapes, High Detail, Premium Casting.

When Shape Matters — Microfusion Delivers.

Sculpted Precision for Brass & Bronze Components.

CAD Design & Engineering

3D models are created in Rhino and Fusion 360, optimised for microfusion in brass or bronze.

Master Piece via CNC or 3D Printing

A high-precision master model is produced on CNC machines or 3D printers and used to create the wax-injection mold.

Wax Injection into the Mold

Casting wax is injected into the mold, generating accurate wax copies of the final component.

Wax Tree Assembly

Each wax part is mounted on a central sprue, forming a “tree” ready for investment casting.

Investment Plaster Fill

The wax tree is placed in a cylinder and filled with investment plaster, creating a heat-resistant mold around the wax.

Burnout in the Oven

Cylinders go into the burnout oven: the wax melts out, and the plaster cures, leaving precise cavities for metal.

Brass or Bronze Casting

Molten brass or bronze is injected into the pre-heated mold, taking the exact shape of the former wax parts.

Cooling & Plaster Removal

After cooling, the investment plaster is broken away, and the metal tree is removed.

Cutting and First Cleaning

Individual pieces are cut from the tree and checked, ready for detailed finishing.

Surface Cleaning & Detailing

Edges are refined, surfaces smoothed, and parts prepared for polishing and galvanic finishing.

Finished Components Ready for Shipping

Costume jewellery quality or hardware pieces in brass or bronze, ready for the client’s chosen finish and colour.

Packaging & Worldwide Delivery

Components are packed, labeled and shipped worldwide. Typical lead time is around 2–3 weeks, depending on quantity and finish.

Iron Formed to Function — Built for Use.

Bending, Pressing, Shaping — Hardware with Structure.

Industrial Precision for Everyday Durability.

Engineering for bending & press tools.

Components are designed in Rhino/Fusion 360 with tolerances that match the shaping method.

Machine-ready tools for consistent results.

Custom dies, forming heads, and bending programs are set for material thickness and geometry.

Hardware formed into its final shape

Iron, brass, or aluminium is bent, stamped, or pressed to create structural components.

Fresh from the press line.

Parts are structurally formed and ready for edge cleaning, finishing, or assembly.

Ready for polishing or galvanic treatment.

Edges are refined and surfaces prepared for plating (nickel, gold, antique, etc.).

Fast lead time. Global shipping.

Final components are boxed, palletised, and shipped locally or worldwide.
