Your Design is the Centerpiece of Our Work

At Carrera, you can enjoy the benefits of the latest technology without sacrificing creativity. If you have drawings or sketches, our technicians will convert them into computer models to your specifications. You can submit your files quickly here

If you already work in CAD, you can upload your files to our secure server and we will build your parts in our facility. We can also work with you to modify any of your existing files to add to your collection. 

Building Your 3D Wax Prototype

3D-Print Jewelry

After your CAD File is finished it is then sent to the 3D-Printer where a wax or resin prototype is built. At Carrera we house over 15x 3D-Printers at our Mid-Factory. Schedule a tour and check out the Carrera Team and learn about jewelry manufacturing. 

Working With A Jewelry Model

While CAD/CAM plays a dominant role in jewelry manufacturing, not every design calls for a CAD file to be created.

Sometimes you might have an original master model that simply needs to be adjusted or repaired in some way. Our model makers are highly skilled metal-smiths that can create a new model from scratch or re-design an older model into a modern best seller.

  • Sizing for special Orders
  • Sprueing for optimum casting
  • Repairs to bent or damaged models
  • Design alterations. 

Going Into Mass Production

Many times the type of rubber that is used to cut your molds will greatly affect your finished product. That is why we offer many different types of molds, depending on your specific needs. We will always be available to help you choose which is best suited to your design. 

  • Regular Mold
  • Mixed Mold
  • Hard Rubber
  • VLT Rubber
  • Silicon Rubber
  • Clear Silicon
  • G-Rubber

Casting Quality Starts Here

The quality of the wax is probably the most underrated part of the casting process.  Any defects in the wax like distortion or internal air bubbles will dramatically affect the end results of your casting. Our mold cutters and wax injectors work very closely to insure that every mold is working perfectly to produce the finest wax possible.

Every wax in our shop is inspected with a 10x loop. We work with several types of waxes including "carving wax". With the use of our vacuum wax injectors we are able to duplicate excellent results over and over.  

Assuring Casting Consistency

Jewelry Tree for Casting

Once we have a wax that has passed through the Quality Control Team it is time to attach the wax to a small wax tree.  Before your wax can be "set up" on a tree it first must be evaluated for the following: 

  • Is the sprue in the right position and the right size?
  • What will be the best angle to attach the wax to the tree?
  • What temperature will these pieces be cast at?

All of this information is recorded so that next time you place an order for the same piece we can maintain consistency in our "Set-Up" process. Over the years, our casting technicians have worked with many designers and artists. We have an extensive 'library of knowledge' of how to cast almost any type of design.

Carefully Tuned Process Control

Jewelry Metal Pouring

By the time we get to the actual casting part of the cycle much of the crucial work is already done. Just as if you were cooking a fine meal, much of the hard work takes place in the preparation. 

If we've done our job correctly in all of the previous steps then the casting process should go smoothly. We have worked with our metal suppliers to come up with exact casting parameters for all of our different metals. Whether you are casting in gold, platinum or silver we already have a specific digital program stored in our database that runs our casting equipment.

State of the Art Technology

Jewelry Casting Ovens

The casting process in an overnight process.  Once our trees are invested and properly cured, they are ready to go into our specially designed burnout ovens. Each oven has been delicately fine-tuned to give optimal results. Each oven runs on a digitally controlled program that was specifically written for each of the many different metals that we cast.

Responsible Manufacturing

Jewelry Assaying

We combine high ethical standards to optimal accuracy in the acquisition and processing of precious metals. All of Carrera's precious metals can be traced to accredited sources that are all verifiable eco-friendly. Please see our Environmental Policy for your convenience. 

Whether we are casting your product or your sending us an item to be assayed we provided you with the exact chemical composition breakdown for all materials present in your jewelry. 

 

Care 

Jewelry Tree Cutting Sprues

We are finally near the end of the process. It is time to carefully remove the castings from the trees. It would be a shame to damage your casting after all of that work. We go to great lengths to assure that your pieces are not bent or accidentally nicked while cutting. If a large piece has a complex sprue system on it, we will remove it from the tree with a jewelers saw. 

At this point your casting will be matched up with an original image of your piece. Once it passes through quality assurance the remaining sprue is cut as close as possible. We don't want you buying more metal then is necessary.
