Within the jewellery manufacturing process, model making is an essential step in ensuring an exceptional quality end product. At Vipa Designs, our comprehensive model & pattern making services cater to clients across the jewellery and silverware industries, combining traditional and time-honoured hand craftsmanship with state-of-the-art CAD/CAM technology to bring even the most intricate designs to life.
Our award-winning master craftspeople understand the importance of refining a model to the highest possible standards to ensure the quality of your castings. Working from your designs or ours, we can create master models from a range of materials to suit your final application, including wax, resin, metal and natural objects. Working with the utmost precision and care to deliver a flawless model free from scratches and other imperfections, we pride ourselves on our commitment to unrivalled accuracy and dedication to our craft.
At Vipa Jewellery we understand the importance of quality and consistency, which is why we take great care in every stage of our lost wax casting process. After creating a master model, it’s time to form a mould. Within jewellery production, mould creation is a vital stage in ensuring the consistency of jewellery items can be accurately duplicated at any time in the future. We can make two different types of moulds; a vulcanised rubber mould for metal masters or a cold cure silicone mould from wax and plastic masters.
The master model is used to form the mould, which forms a negative impression of the model enclosed. After being vulcanised and cured, this rubber mould has the ability to withstand extremely high temperatures without losing its structural integrity. Once the model is released, pressurised molten wax is injected through the sprue opening in the mould. After the wax cools, the mould is peeled open to reveal an injected wax model, which is then finished by our master craftspeople to eliminate any imperfections, and subsequently encased in investment material, cured, and incinerated.
The wax model is then melted away (hence the term lost wax casting) to leave a cavity within the investment mould, ready for molten precious metal to be poured into it within the casting process.
With market-leading skills in both traditional model making and CAD/CAM 3D printed technologies, we’re here to help at every stage of taking your vision from concept to completion – from one-off, bespoke products to entire collections and ranges.
