FREQUENTLY ASKED QUESTIONS












CASTING

  • CASTING CAD/CAM MODELS

Please be aware that some of the CAD/CAM models do not follow the laws of metallurgical physics. These technical design flaws can sometimes cause spruing and casting issues such as: breakages, porosity, non-fills, and other casting defects - therefore we are unable to guarantee successful castings of these models.


  • CASTING RESINS

The recommended burnout schedule for resin models differs from our standard one and takes longer to process. While we are able to successfully cast some types of resin, we cannot guarantee this for all types due to many factors, such as: incorrect curing of the resin, bad chemical reactions, different burnout requirements etc. To ensure the highest quality of castings we strongly advise you to use CAD/CAM models rather than resin.


  • ADDING/CHANGING SPRUE

To ensure the best quality of casting our specialists have the final decision as to where to sprue the design (unless specifically requested otherwise). The position of the sprue will differ, depending on which metal the design is being cast in.


  • RECYCLED ALLOYS

Thanks to our high standard equipment and machinery we are able to provide precious metals castings of the highest quality. Our silver and gold alloys are 100% recycled.


MOULD MAKING

  • WHAT TYPES OF MOULDS DO YOU MAKE?

We offer two types of moulding; hot rubber moulds and cold-cure moulds.


  • WHAT IS A COLD CURE MOULD?

It is a liquid silicon rubber mould that vulcanises at room temperature so does not require any additional heat or pressure to cure.


  • ADDING/CHANGING SPRUE

To ensure the best quality of casting our specialists have the final decision as to where to sprue the design (unless specifically requested otherwise). The position of the sprue will differ, depending on which metal the design is being cast in.
