25+ years manufacturing premium jewelry for the world's wholesale market — from our Bangkok factory to your customers.
Univox Manufacturing Co., LTD. was founded in Bangkok, Thailand with a single mission: to produce the finest electroformed and cast jewelry for wholesale buyers worldwide. What began as a small workshop focused on silver electroforming has grown into a full-service B2B jewelry manufacturer.
Today, Univox supplies silver and gold jewelry to leading brands, boutiques, and importers across the United States and Europe. Our products reach end consumers on four continents, carried by buyers who trust our quality, reliability, and ethical manufacturing practices.
We operate from a purpose-built facility in Bangkok that houses our electroforming baths, casting division, polishing workshop, and quality control laboratory. Everything happens under one roof — giving us complete control over quality at every stage.
These principles guide every decision we make — from how we manage our factory to how we work with our buyers.
Every piece we ship represents our reputation. We invest in process controls, equipment, and training to maintain the highest quality standards in the industry.
We see ourselves as manufacturing partners, not just suppliers. Long-term relationships built on transparency, reliability, and shared success.
