Lost Wax


The basic idea of ​​lost wax casting has been used since the Bronze Age. At that time, beeswax and clay were used. Today, modern industrial waxes are used for the production of ceramic casting mould.
This modern lost wax process allows for profitable work even in small quantities. The accuracy achievable today makes it possible to cast integration-ready parts. Extensive design possibilities make the process an alternative for workpieces with high machining costs, both for small and large series.

Wax Injection Mould


Mould manufacturing in accordance with customer documentation.
The drawing and the 3D model are the basis for the manufacturing of the mould for the start of production.
In mould making, we use the latest technologies such as 5-axis machining centres and the latest CAD systems. An optimally designed and produced shape is the basis for quality-oriented fine parts.
Owing to our own tool shop, we have control over the process right from the start.
 
Wax Model Manufacturing.
In the casting process, firstly, a wax part is needed for the cast component. This is produced with the use of spraying machines. Subsequently, the individual wax parts are glued together to form "pouring clusters"

Casting Mould


Production of ceramic shells is in the hands of experienced professionals.
First, the clusters are immersed in liquid ceramic and then sanded down. Ceramic dipping is repeated 6 to 10 times, and each coating is dried before the next layer is dipped.


Dewaxing and firing the ceramic shell.
Wax is removed from the ceramic shells using steam and pressure. Then the empty ceramic shells are fired at approx. 1000°C. Now the ceramic tray is sufficiently firm and ready for casting.

 

Casting


Metal Casting
The liquid melt is poured directly into the still hot glowing shell. This results in a good surface and very good dimensional accuracy.

Unpacking - Separating


Removing the ceramic shell
Separating the cast parts from the casting system (cluster)



Cleaning


Removing the residual ceramic by sandblasting and pickling.
 


 

 


Grinding


Removing sprue residues by grinding.
 
 
 
 


 

Further Processing


Depending on the customer's request, the parts are heat-treated and/ or mechanically processed.
Bürstlein offers you various surface treatments, for example:

Zinc Plating
Nitriding
Nickel Plating
Polishing
Electropolishing
Painting
Powder Coating



 



Quality Assurance


Our certifications are only the documentation of our own quality requirements, which mostly go beyond the requirements of our customers.

A 0-error target is applied

We do not compromise on quality.
The complex processes in a precision investment casting process require constant checking and further development of the processes in order to always provide our customers with the optimum product.


Starting with the wax models for the moulds through the continuous inspection of the melt up to the internal final acceptance, all test steps are documented.
Modern measuring systems, optical and tactile, form an important basis here.
Individual testing tools ensure that each part performs its purpose reliably.
