Frequently asked questions
What do castings cost?
It is impossible for us to quote prices for labor charges without first seeing the piece or pieces in question. We invite you to send your designs to us and we will gladly give you an estimate before any work is begun. Of course, the integrity of a client’s creation is always held in strict confidence whether sent for pricing or for production.
How long does it take to make a mold?
The process of making standard size rubber or non-shrink molds generally takes approximately a day or two.
How long would it take to complete my casting order?
Depending on the size of the order, most waxes received before 2:45 pm (Eastern time) Monday -Thursday are cast and ready to ship the next day. In order to provide you rapid turnaround on your job, we suggest you ship your wax, so it arrives via FedEx or UPS mid-morning.
Bulk order timelines vary. Should you be working with a specific deadline, please let us know.
How much do molds cost?
Molds start at $25.00 (for example, a basic ring) . Charges increase depending on size and complexity.
Are there any other costs?
In addition to casting labor and mold charges, there are the metal charges, based on the daily market per pennyweight (dwt.), finishing and stones setting (if these options are chosen) and shipping and handling.
Who keeps my molds?
The design is your own; you are only charged for the labor and cost of the materials incurred in making the mold, and it is returned to you with your order. You can send it back to us each time you need to reorder. We can also hold your molds on our premises which will simplify your ordering process if you are ordering frequently from these molds.
What are my casting size limitations?
Our standard casting size limitations are generally 4½ inches by 6¾ inches. We can accommodate some larger pieces using shell technology; please contact us with your specific details.
What type of metals do you cast?
We cast in platinum 90-10, 95-5, gold 24k - 10kt in the following alloys: yellow, white, green, and pink. We also cast in sterling silver, tarnish-resistant sterling silver, lead free brass, silicone bronze, and white bronze. If you require additional materials or colors, let us know.
How will my order be shipped?
We ship via FedEx, UPS and USPS.
Are my designs insured in shipping?
Models for molding are generally insured for $100.00 each unless a higher amount is specified. Molds are insured for the average cost to remake the mold. Wax models that are cast into metal are not insured for any additional value over the invoice unless the customer so specifies.
Can I drop off or pickup my order?
We always welcome visits from our customers. Call us for directions and/or an appointment.
How do I pack my waxes for shipping?
Your waxes and originals are very fragile and delicate pieces. Please take great care in packing them; the parcels are often abused in shipping and they can break easily. Use plenty of absorbent packing material around each individual piece, preventing them from movement, and use a large sturdy box. Of course, always include a list indicating the number of pieces enclosed so that we'll know if something arrives broken.
Is there anything else I need to do when sending in an order?
Your letter of instructions should include your shipping address as well as a list of contents with details as to your order for each item, indicating quantity and metal. Indicate if you require an estimate prior to producing your order, and always include a telephone number and email address.
Can I use my own metal?
In order to be able to supply you with the highest quality castings, we must know the metal we are using. Any metal you send us may have even the slightest impurity in it which could affect your, as well as everyone else’s castings, so we cannot add it to our inventory. We will however cast a separate flask with your metal, but the casting quality will not be guaranteed. Please contact us for details before sending metal with your job
Is there a minimum order?
There are no minimum casting orders, however if we are setting up a separate flask for your casting in your metal there will be a minimum charge of $35.00.
Does IMC provide finishing services?
Yes, we do provide a complete variety of finishing services, which include anything between removal of sprue and tumbling and up to supplying and setting of stones. Please contact us for additional information.
What are my payment options?
Orders may be prepaid via credit cards or COD. Credit terms are extended to frequently reordering commercial accounts which are rated by the JBT. after completeing a credit application.
What type of molds are available ?
We offer traditional rubber molds (highest shrinkage rate) and Castaldo Long life RTV molds (lowest shrinkage rate). Metal molds for plastic and wax injection are available as well. Generally, there is 1% to 10% shrinkage from master to finished piece. Shrinkage has been calculated from in-house tests and manufacturer specifications and may be different depending on model geometry. (Example: Marquise dimensions change differently than squares and outside dimensions change differently than inside dimensions.)
Sprue and design issues
We strive to deliver the best quality cast product. Often we receive esthetically beautiful waxes or computer generated models that do not account for the natural laws of precious metal flow dynamics. These technical design issues often cause porosity, non-fills, and other casting defects.
Based on our experience we can compensate for these issues by changing sprues, adding risers, adjusting flask and metal temperatures or recommending a change in the model. If you choose not to have modifications to your molds or models, we cannot guarantee satisfactory results. We reserve the right to reject a model, mold, or waxes if we feel that the results will produce poor quality due to pre-existing uncorrected potential issues.
We will gladley use your existing mold or metal model, we may recommend modifications to ensure quality. We may need to replace, modify, move, or completely alter the feed sprue system of your metal model to get the best casting results. Minor alterations are typically done at no charge. Major alterations to molds, or sprue changes on models, are done for a fee. Sprue changes on models will also require making a new mold for a minimal fee. We will contact you in advance regarding any recommended changes.

Do you provide 3D scanning services ?
We can capture and manipulate physical objects and bring them into the digital world using a 3D scanner, In many cases it can eliminate the lengthy and costly mold making processes.
Match an existing piece
Reproduce irreplaceable heirlooms
Digitally create organic pieces (Shells, fossils, twigs, food)
What is the difference between CAD and CAM services?
CAD (computer-aided design) describes the use of computer software programs to create 2D or 3D models.
When the design phase using the CAD software is complete, we deliver a screenshot from the. STL or .3DM file(s) along with digital renders to illustrate the entire design and layout of the jewelry piece for final approval. That file is then used to create physical prototypes of the jewelry,
CAM (computer-aided modeling) is the use of software programs and machinery to create and manufacture a 3D object. Upon completion of working with a CAM program and machines, a 3D wax model is created which physically represents the way the final product will look.
How do I submit my design ideas ?

Do you provide CAD design services ?
Submit your jewelry sketch or a photo and we’ll design a 3D CAD model based on your specific instructions.When the design phase using the CAD software is complete, we deliver a screenshot from the. STL or .3DM file(s) along with digital renders to illustrate the entire design and layout of the jewelry piece for final approval. That file is then used to create physical prototypes of the jewelry,
