Platinum, gold, and silver casting in NYC’s Diamond District

Precious Metals Casting

Specialized precious metal casting with careful process control for established trade clients.

Premium Quality Castings

Our precious metal casting practice supports existing trade clients with gold, platinum, and silver manufacturing. We work with wax and resin patterns and select the process to suit the alloy, geometry, and intended finish.

Computer-controlled casting equipment supports consistent process management. Technical review and quality control address detail reproduction, surface condition, and suitability for subsequent setting and finishing.

Please email production-ready files or pattern details, alloy specifications, quantities, and finishing requirements. Pricing and scheduling are confirmed for each accepted project. We maintain a selective production schedule for existing trade clients. We are not currently accepting new manufacturing accounts or collection-development projects. Please email technical specifications and production requests. All workshop visits are by appointment only.

Gold and Silver

Recycled

In our manufacturing shop, not a single piece of the metal strap would be thrown away. We make jewelry made entirely of recycled silver and gold by utilizing our production expertise.

Testimonials

★★★★★

I met with Carlos to talk about a project in silver. the pieces are something that would be nearly impossible to make molds for so I needed to print 3D wax. He was understanding, knowledgeable, and accommodating. His craftsmanship is like no other in NYC's jewelry district. The castings are gorgeous. Your project is in good hands with Carlos and Tech-Designs.

For the people who reads this review and need a honest opinion regarding Tech Design I can say one thing, just this year alone Carlos did over 20 projects for us in witch we generated over 3 million in purchase orders. His CAD skills are at the highest level of jewelry manufacturing and because he is a jeweler and designer he makes everything work flawlessly. I would definitely recommend Carlos and Tech Designs.
