Lost Wax Developments Ltd utilise the latest technologies to produce castings of superior quality in a range of different materials.  We pride ourselves on our high levels of performance, not just for the finished items we produce, but throughout the entire production process, working closely with each individual customer from initial concepts to ensure their visions and designs are realised.

We employ a range of different technologies to produce our castings, including investment casting (lost-wax casting), 3D thermojet wax printing, stereolithography modelling, silicone tooling, reverse engineering and hand-crafted modelling.

Our customers span a diverse range of industries from oil & gas and fire & safety to automotive and even fine art, and over the years we have produced a variety of products including: safety harnesses, water impellers, drill head rotors, food mixing paddles, blades for the marine industry, trophies and sculptures.  We can cater for one-off prototypes as well as high-volume production runs, and our castings range from 5grams right up to 75kgs.

Wax Injection and Assembly

The initial step in the Lost Wax Development Ltd casting process is wax injection. Metal dies are machined which are then injected with wax to make the casting. They are then assembled and placed on a runner system ready for the next step in the process, which is Shell Manufacture.

Shell Manufacture

The assembled wax patterns then need to have a ceramic coating applied and this is done robotically. The assemblies are dipped in the ceramic coating and stuccoing until the desired shell is achieved.

De-Waxing and Casting

After the ceramic and stuccoing coating has been applied and the shell is formed, the wax must then be removed.  The shell is placed in a furnace at temperatures over 1000°C for preheating.  Once the right temperature has been reached molten metal alloy, which has previously been melted, is poured into the shell and then allowed to set.


The final process undertaken by Lost Wax Development Ltd is finishing, which happens once the ceramic shell and metal contents have fully cooled.  The shell is now removed and the metal casting undergoes a series of processes to achieve the desired finish.  All castings are carefully cleaned within the confines of a carousel shot blast cabinet and then further blasting techniques are applied to reach a customer’s predetermined specifications.

General Casting Tolerances

Lost Wax Developments Ltd works within a set of dimensional tolerances which can be found by following the link.  This information includes details for angular tolerance, linear tolerance, concentricity, ovality and flatness and we also provide details of our Form of Supply with all quotation documentation.  If you are in any doubt as to the suitability of your project with regards to the general tolerances stated then we would welcome you to discuss this with us.

Thermojet Solid Object Printer

Lost Wax Development Ltd is pleased to be able to offer 3D modelling with our 3D Systems Thermojet printer.  Its state of the art printing capabilities produces solid models from 3D CAD data allowing you to bring your designs to life.  It offers maximum single print dimensions of 250x190x200mm, however by printing separate components much larger models can be constructed by assembling the smaller pieces together.

Stereolithography (SLA) & Silicone Tooling

Our SLA machine produces intricate parts from photosensitive epoxy resins, through a process of complex layering, directly from a 3D CAD model. Stereolithography machines deliver high levels of accuracy as well as speed, allowing you to visualise prototypes and new parts without delay. Parts produced via this method can be used for fit, form and function and the finished parts are of such high quality that they can be used as show parts.

3D Scanning

3D scanning allows CAD modifications to be made to existing physical parts and objects.  We use traditional reverse engineering methods to scan the object’s dimensions, which then produces a CAD file that is an accurate representation of the object. In CAD format, any adaptations and alterations can then be made in order that a new object can be manufactured.

Metal Specifications

Lost Wax Development is able to work with a wide range of different metal alloys to produce our high quality castings in order that we best meet your specific requirements.  These include, but are not limited to:

  • Carbon and low alloy steels
  • Tools steels
  • Stainless and heat resistant steels
  • Cobalt based satellite type alloys
  • Nickel
  • Brasses
  • Aluminium

The full specifications of each alloy can be obtained by following the link.  Please contact us if the particular alloy you are looking for is not shown and we will advise if your requirements can be catered to.
