Advanced Zamak Die Casting for High-Quality Furniture and Decorative Hardware

Furniture and decorative hardware must deliver functional performance, aesthetic appeal, and tactile quality. From drawer handles and knobs to door hinges and trim accents, these components are expected to maintain their appearance and durability through years of use. Zamak die casting offers an ideal manufacturing solution for producing high-strength, visually appealing metal parts at scale, with excellent dimensional control and surface finish.

At Neway, we specialize in zinc alloy die casting using premium Zamak grades tailored for furniture and decorative applications. Our advanced tooling and finishing capabilities allow us to produce detailed, consistent, and customizable hardware solutions for global furniture and fixture brands.

Why Zamak Die Casting Is Ideal for Furniture Hardware

Zamak alloys, composed primarily of zinc with aluminum, magnesium, and copper, are known for their excellent castability, surface finish potential, and mechanical strength. These properties make them highly suitable for producing durable and aesthetically refined hardware.

Key Advantages

• Excellent dimensional stability with tolerances of ±0.05 mm

• High surface definition for fine details and logos

• Tensile strength of up to 400 MPa (Zamak 5)

• Density of 6.6 g/cm³ for a substantial, high-quality feel

• Compatibility with decorative electroplating, painting, and powder coating

Zamak parts are ideal for reproducing smooth contours, sharp edges, embossed logos, and tactile elements that enhance user experience in high-end furniture hardware.

Common Decorative and Furniture Hardware Applications

Zamak die castings are used in both structural and decorative roles across home, office, and hospitality furnishings.

Zamak Alloy Selection for Decorative Hardware

Neway utilizes multiple Zamak alloys depending on the application's design complexity, strength requirements, and finishing needs.

Zamak 5 is typically preferred for functional hardware such as hinges or pull handles, while Zamak 3 and 7 are used where cosmetic appearance is the primary concern.

Dimensional Precision and Design Versatility

Furniture hardware often features intricate profiles and must meet tight fitting tolerances for seamless installation and function. Zamak die casting enables complex shapes to be formed in a single mold cycle, eliminating secondary processes.

• Wall thickness: as low as 0.8 mm

• Feature detail depth: 0.2–0.5 mm for logos or decorative textures

• Draft angles: down to 0.5° for minimal material removal during ejection

• Tolerances: ±0.05 mm general, ±0.02 mm for mating components

• Surface finish: Ra ≤ 1.6 µm after tumbling or polishing

Undercuts, slots, and threads can be directly cast, reducing machining time and cost.

Surface Finishing for Decorative Applications

Surface aesthetics are critical in furniture hardware. Neway offers advanced post-processing solutions that elevate each part's visual and tactile quality.

• Electroplating: gold, nickel, brass, antique bronze, and chrome finishes

• Powder coating: matte, gloss, or textured coatings in RAL/Pantone shades

• Painting: durable coatings for color-coded or brand-matched pieces

• Polishing: to achieve mirror-like or satin textures

• Assembly: press-fit bushings, threaded inserts, or multicomponent units

All finishes are RoHS-compliant and meet household use standards for abrasion resistance and environmental safety.

Tooling and Scalable Production

Neway offers in-house tool and die making optimized for both decorative detail and cost-effective mass production.

• Tool material: H13 steel hardened for long service life

• Tool life: 250,000 to 500,000 shots typical for Zamak applications

• Lead time: 3–5 weeks with DFM and mold flow validation

• Shot cycle time: 20–35 seconds

• Part size: up to 200 mm in width; multi-cavity tools for smaller parts

• Rapid prototyping with soft tooling or hybrid molds available

Batch production supports volume ranges from 5,000 to 1 million+ units annually, with full process repeatability.

Case Study: Decorative Cabinet Handle with Multi-Finish Options

A luxury furniture brand approached Neway to create a line of cabinet handles featuring:

• Intricate logo recess (0.3 mm depth)

• Finish variations: antique brass, satin nickel, matte black

• Mounting hole positional tolerance: ±0.02 mm

• Ra ≤ 1.2 µm surface roughness before plating

• Quantity: 300,000 units annually in three SKUs

Neway developed a multi-cavity die system with interchangeable finish blocks and implemented in-line CNC machining for mounting faces. Handles were electroplated in three finishes and assembled with press-fit threaded inserts. The project achieved a first-pass yield of 99.1% and maintained visual consistency across finishes.
