Die benefits of the lost wax casting process are obvious:
Faithful conversion of the model into metal - no problems with undercuts at spatial forms - the artistic freedom ist virtually unlimited. Gugg has mastered this technique.
Full-plastic and semi-plastic figures. The molding material of the original model is usually made of plaster or clay, fired or unfired, clay, as well as plasticine and paper mache.
Silicone molds have a unique price-performance ratio and belong to the customer (copyright protection). The molds are professionally stored by us for free. There are several casts possible from these molds, also in concrete, plaster or plastic.
Advantage: model directly in wax (Attention: Observe wall thicknesses!) and cast in lost wax form afterwards.
Mode of operation:
- Model Delivery
Models with solid suface, also "lost wax models". Gentle handling, the original will not be damaged. Wax models will be stored in a special, refrigerated room. Model intake on request throught Guggs own fleet.
- Silicone negative mold or clay form
Creation of a mirror image of the original - the negative.
Silicone mold: advantage: longer lifetime for more casts.
Clay form: less expensive, but short lifetime
Manufature of negative molds in-house.
- The wax positive
Through remodeling arises from the negaive mold by applying a wax coating the positive mold - the unchanged original impression of the model.
- Cuts and feeds
The basis for a uniform and high-quality cast with homogenous, closed casting skin are great care, adequate placement and professional installation of the feeds.
- Filling with core mass
For quality and weight reasons, most objects usually are implemented hollow. The wax positive must therefore be filled carefully wit a fine core mass.
- Insertion
To embed the finished trimmed and retouched wax model in the fireclay fom.
- Drying - Cooling
The melting out of the wax model happens in a drying ofen. Of special importance is the uniform temperature increase and the exact holding of the maximum temperature until the process is completed. Slow, steady cooling.
- Casting
Pouring the metal in the resulting cavity in the fireclay form with optimum casting temperature and casting speed. We use only certified metals.
- Peeling, Cleaning
Careful removal of the fireclay, cleaning with water pressure only in order to avoid damage to the cast surface.
- Chasing, Patination
Further processing, removal of sprues and vents. Chasing, assembly and welding for large objects. Change of the surface color through patination. Traditional processing technology, proven over centuries, ensures optimal results. For details, see HERE
- Quality Control
Our name must stand for quality - at Gugg this promise has been taken literally for generations. Only quality can endure.
