LOST WAX INVESTMENT CASTING SPECIALIST
CIREX is one of the largest steel-casting companies in the world and casts using the “lost wax” method. With this method, lost wax castings can be produced with a high degree of dimensional accuracy and complex shapes. This method also provides engineers with a significant degree of product design freedom and choice of materials. Your specific desires and requirements can be incorporated in the cast pieces.
CIREX is one of the largest lost wax foundries in the world and specialises in the production of steel investment castings. CIREX has operations in the Netherlands and the Czech Republic. The foundry in the Netherlands is the larger of the two and has a melting capacity of 4.000 tonnes of steel per year. Due to a fully automated process, our Dutch location is perfectly suited for large series of investment castings, where a high-level quality is being guaranteed. CIREX composes her own steel alloys so almost any type of steel can be cast.
The Czech foundry specialises in producing smaller series of lost wax investment castings in steel and uses similar operating processes as the Dutch foundry. The flexibility of our production is most important and comes first. This allows the foundry to perform especially well when it comes to casting complex castings against market prices. In total, the Czech foundry owns four semi-automated casting installations with a total melt capacity of 1.000 tonnes per year.
FINISHING & MACHINING IN THE CZECH REPUBLIC
This Czech facility finishes the castings from both foundries according to product specifications. This includes blasting, sanding or machining the castings by means of drilling, tapping and milling. Due to the fact that CIREX owns a modern, specialised finishing department, components produced by CIREX can be delivered ready-to-install. At our Czech facility we can perform the following process steps:
- Heat- and surface treatments
- Calibrating & Machining
- Assembly of subcomponents
CIREX castings are applied in the automotive and aeroplane industry, pharmaceutical and food industry, process technology and machine construction all over the world. Renowned manufacturers use castings that have been cast in the CIREX foundries. These components are for example used in motors, gearboxes, paintmixers, balers and hydraulic transmissions.
LOST WAX INVESTMENT CASTING PROCESS
This production method is also known as precision casting and is one of the oldest casting techniques. It is often utilized because it has the following advantages:
- Complex shapes can be cast as a single component;
- Products with undercuts can be cast;
- Machining costs are significant reduced;
- A draft angle is not required;
- Precise tolerances are achieved;
- Surface quality is extremely high;
- Last but not least, almost any steel alloy can be cast
