GUARANTEE Your Casting Quality and Use Our Mold Making Service:

You spend a lot of time caring for your customers, designing and modeling; let us do the casting for you and save your energy and talent for what you love to do.

We can select the mold material that best suits your piece. Generally, there is 1% to 6% 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 dimension change differently than inside dimensions.) It is your responsibility to plan for the dimensional change in your parts based on your needs. Consider your model’s finish, mold material, finishing process and final part requirements. Please call or e-mail with any dimensional change (shrinkage), concerns or for further explanation.

If you want us to work from your mold or metal model, it is common that we must make modifications to them to assure quality.  We may need to modify your mold with vents or internal modifications to work with our system. We may need to replace, modify, move, or completely alter the feed sprue system of your metal model to get the best casting result. Minor mold 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 require new molds to be made. These molds are also made for a reasonable fee. You will be advised in advance if this is necessary and you can make that decision. 

If you choose to have no modifications to your molds or models, we cannot guarantee that there will be no seams or perfect fills. We always do our best to give the highest quality wax and castings with the tools and materials we have available. Additional wax injection charges may be applied based on the wax shot to acceptable wax ratio and the amount of time required to clean the waxes from your mold. We reserve the right to reject a mold if we feel that the labor required to produce the order exceeds profitability. 

A great deal of time, energy, and testing is spent at Hoover and Strong by our product development department to engineer absolute casting quality into each of our production products. Most designers, custom carvers, and retail jewelers don’t have the luxury to test their one of a kind or limited production designs in this manner. We often receive esthetically beautiful waxes and computer generated models that do not follow the natural laws of metallurgical physics. These technical design issues sometimes cause porosity, non-fills, and other casting defects. We do our best based on our experience to compensate for these issues with sprues, risers, flask and metal temperatures but without testing, it’s a best "guess". Hoover and Strong can not be responsible for these types of defects. If there is a mold available we sometimes recast your parts at no charge to you. These additional casting trials will be at our discretion and beyond that additional trials will incur a charge.

If you have spent a lot of time or money making a hand carved wax or rapid prototype, it is always in your best interest to make an RTV mold of your valuable design. The small $30 investment in a mold is far cheaper than re-carving or rebuilding your design again in the unlikely event of a less than satisfactory casting.

The mold materials that we use are listed below along with their associated properties. The casting and mold department will make individual decisions on type of mold needed based on model sent. Refer to the model section of our casting tips article.

There are rare times that we may refuse to cast a wax at all if the failure is assured based on our experience. We cannot afford to expend our time and labor when we are certain of failure based on our experience. 

Before you send your waxes, look for:
Air bubbles near the surface, heavy file marks, flashing, incomplete prongs, bearings or bezels, dirt or metal filings on or in the wax, small gaps and/or cracks in your part.

Security:
Hoover & Strong will never copy or infringe on a customer's copyright and is not liable for copyright infringements by others. It is the customer's responsibility for maintaining ownership of the submitted design. Hoover & Strong will absolutely never cast designs that have trademarks other than that owned by the sender. These trademarks can be real or implied, i.e. an actual stamp or pieces with known protection such as proprietary designs. Download the H&S Nondisclosure Agreement. Please package wax models very carefully in a small box. We suggest that you don't use tissues to wrap the waxes. Use a soft, fibrous material that will not leave behind lint. Tape the small box inside a large box before mailing.  

Hoover & Strong is not responsible for lost or damaged models during shipment.

Send models and waxes to Hoover & Strong, Attention: Contract Casting Department. Fed Ex or UPS are best; U.S. Postal Service only if it is insured and able to be tracked.
