Casting, Forging & Tooling
In-House Tooling, Casting and Forging.
Our tooling team works beside casting and hot forging, so a drawing or sample becomes a repeatable component with fewer handovers.

Glass Fittings, One System.
At our factory in Thai Binh, Vietnam, tooling, casting, forging, CNC machining, polishing, plating, assembly and inspection work as one system for repeatable glass fittings and OEM hardware.
The Site
Thai Binh, Vietnam. Production halls, tooling, plating lines, a test laboratory and raw-material warehousing.
One Team. One Production System.
Customers work with one Gold Classic team from the initial concept through production and delivery, supported by our factory in Vietnam. Requirements, drawings and approvals are handled by Gold Classic; the factory turns them into tooling, parts, finishes and packed goods.
The factory operates under the name VTAC. It is where every process described on this page takes place.
01End-to-end process
From the Drawing to the Carton.
Nine stages turn a drawing into finished glass fittings and OEM hardware, inside one organisation. Each stage is managed with knowledge of the one before and the one after.
- 01
Design Support
Understanding the application, drawings, material and functional requirements.
- 02
Prototyping
Checking structure, assembly and surface effect early, while changes are still inexpensive.
- 03
Tooling
Our in-house tooling facility turns the requirement into moulds, dies and process conditions that can be adjusted and repeated.
- 04
Casting & Forging
Investment casting or hot forging, selected according to geometry, strength, quantity and material.
- 05
CNC Machining
Dimensions, hole positions and mating faces are machined where the drawing demands control.
- 06
Polishing
Surface flatness, grain and appearance are prepared for the intended finish.
- 07
Plating & Finishing
Electroplating and ED coating on our own lines, to the approved colour and surface.
- 08
Quality Control
Inspection against drawings, approved samples and the agreed inspection specification.
- 09
Assembly & Packaging
Assembled and packed according to brand, channel and transport requirements.
02In depth
Two Capabilities in Depth.
Precision CNC
Precision CNC for the Features That Matter.
Hole positions, gasket seats, pin bores and mating faces are machined and checked against the drawing.

Forged In-House, Finished In-House.
Our forging line supports repeatable production of architectural hardware components, from heated billet and precision tooling through trimming, CNC machining, polishing, plating and final inspection.
What We Make
- Brass hinge bodies and hinge plates
- Customer-specific brass components developed with in-house forging dies
Process Envelope
- Material
- Hot-forged brass.
- Part size and weight
- Matched to the press and die for each component at drawing review.
- Geometry
- Solid, load-bearing forms with machined interfaces: hole positions, mating faces and bores are finished by CNC after forging.
- Batch size
- Repeat production with dedicated dies.
- After forging
- Trimming, CNC machining, polishing, in-house plating, inspection and packing within the same production system.
Production equipment
| Press capacity | Quantity |
|---|---|
| 150 t | 1 |
| 200 t | 3 |
| 300 t | 2 |
| 630 t | 1 |
Hot-forging presses. Mechanical transfer arms or FANUC robots assist billet handling on selected presses.
04Finishing
Polishing and Plating, on Our Own Lines.
Electroplating and ED coating are operated in-house, directly after polishing. Finishes are approved on physical samples and carried into production against that reference.
05Quality control
Inspected Against Drawing, Sample and Plan.
Every part is checked against the drawing, the approved sample and the inspection plan. Our factory operates a quality management system to ISO 9001:2015, assessed annually. The current certificate is available on request.
01 — Dimensional inspection 
02 — Test fixture, quality laboratory 
03 — Hinge under test 
04 — Final check before packing
