Designers and jewelers across the globe rely on Castimize to turn their 3D models into real metal objects. Whether you’re creating custom parts, delicate earrings, or meaningful jewelry pieces – we’re here to bring your vision to life.
Below, three of our customers share their experiences – and the results speak for themselves.
Testimonial 1: Jason Oshannesy
Functional parts for his mini train project – Brass
I wasn’t sure how I’d finish my models. The team at Castimize reached out, promising superior quality and service. To test them, I sent over some challenging brass parts—and the results were outstanding. The details are flawless, and the surface finish is impeccable. Thanks to Castimize’s lost wax process, I’ve achieved an entirely new level of detail on even the smallest components, without the painstaking effort of crafting them by hand. I couldn’t be happier with the results!
Castimize: Jason’s precision parts needed more than just casting — they required detail, accuracy, and a flawless finish. Our lost wax process was the perfect match. We also recommend to have a look on Jason’s Facebook page to follow his progress on his mini trains and to see video footage!
Testimonial 2: Max B.
Earrings – 18K Yellow Gold Plated Brass
I greatly appreciate the responsiveness and capabilities of the Castimize team. For example, I was able to order a chain and bar T-bar toggle attached to my earring design. My wishes were then refined by Castimize and executed perfectly.
By using Castimize, I can stay true to my initial design which is very important for me. The final earring design had many small details that I asked Castimize to try to keep during the polishing process, which they managed to preserve. The final product exceeded my expectations and I will definitely come back in the future.
Castimize: Max came to us with a detailed earring concept. Together, we refined it into a polished final product, without compromising on his original design.
Testimonial 3: Kathyann Saleem
Pendant and Signet ring – Silver
Why I chose Castimize for my jewelry business.
From the beginning, their professionalism and reputation made me curious to see how they could support my jewelry designs.
Their online platform is incredibly user-friendly — uploading my .stl files is straightforward and hassle-free. From my very first order, their customer service has been outstanding — responsive, helpful, and genuinely invested in ensuring my pieces turn out exactly as I envisioned.
I primarily cast in silver when designing my jewelry. My pieces are fairly uncomplicated, but I’m particular about the finish and want them to match my vision perfectly. To test Castimize, I purposely submitted two designs that had caused issues with past companies:
- An engraved pendant with an interlocking finding, to be finished in Antique Silver.
- A much-loved Signet Ring with a star engraving, to be finished in Polished Silver.
Before placing the order, I reached out to the Castimize Team to confirm the details. They listened carefully and understood exactly what I wanted. When the pieces arrived, the results were beyond my expectations — the finishes were flawless, and the attention to detail was exactly what I had hoped for.
My goal is to grow my business from a side hustle into a full-time venture, and I’m confident that Castimize will grow with me. I look forward to continuing this collaboration as my business expands!
Castimize: From initial upload to final polish, Kathyann challenged us with complex silver designs — and we delivered. We’re proud to support her journey as her brand grows.
