Furniture Hardware Die Casting - Zinc & Aluminum

Furniture hardware is one of zinc die casting's natural homes: handles, hinges, connectors, locks, and fittings that must look flawless on the showroom floor while surviving years of daily use. KastMfg produces furniture hardware for OEM and private-label programs, from as-cast decorative parts to load-bearing structural fittings.

Why Zinc Dominates Furniture Hardware

Requirement	Zamak delivers
Mirror-class chrome plating	As-cast Ra 1.6 µm surfaces plate directly
Thin walls, fine detail	0.8 mm walls, crisp logos and textures as-cast
Solid, quality feel	6.6 g/cm3 density reads as "premium" in the hand
High volume economics	Hot-chamber cycles of 15 to 30 seconds
Thread strength	Cast or tapped threads hold assembly loads

Zamak 3 covers most decorative furniture hardware; Zamak 5 for load-bearing fittings; aluminum (A380) for larger structural parts like chair bases where weight matters.

Finishes That Sell Furniture

Furniture hardware lives or dies on finish quality. In-house and partner-line options:

• Chrome plating - bright, brushed, or satin over copper-nickel undercoats
• Nickel and black nickel - warm metallic looks
• Powder coating - matte black, white, and RAL colors with excellent scratch resistance
• PVD-style finishes - brass, bronze, and gunmetal tones via plating stacks
• Antique finishes - brushed antique brass and copper for traditional lines

Salt-spray testing (48 to 96 hours neutral, per finish spec) verifies bathroom- and kitchen-grade corrosion resistance before shipment. See surface finishing and zinc plating for process detail.

What Furniture OEMs Should Know Before Tooling

1. Finish first. Specify the finish at DFM stage - plating-grade surfaces need different die polishing and zero visible flow lines, which affects gate placement
2. Weight targets. Zamak's density is a feature in handles but a cost in shipping; aluminum or hollow-back designs cut freight weight on big programs
3. Assembly interfaces. Cast-in threads, press-fit pins, and spring features are all routine - tell us the assembly method and we design the interface into the die
4. MOQ reality. Furniture hardware tooling pays back around 10,000 pieces per SKU; low-volume options exist for collection testing
