Sand Casting
Aluminum sand casting from the Austrian market leader. Based in Klagenfurt, MWS has been the Austrian market leader in the field of aluminum sand casting for many years. You too can rely on absolute professionalism and long-standing expertise in the field of sand casting.
Advantages of the Sand Casting Process
Greater Design Flexibility
Sand casting offers the greatest possible design freedom. This ranges from flexibility in component development to the production of closed profiles.
Improved Further Processing
The gentle sand casting process enables uniform mold filling, which ensures additional, problem-free processing of the castings through welding.
Fast and flexible implementation
Sand casting ensures a short realization period for your project and maximum flexibility. We can also react rapidly to any changes during development.
Economical Production
Every 50 seconds, a mold is opened, and a finished component sees the light of day. Chained automated processes enable fast and highly flexible production.
Greater Design Flexibility
Pressure from all sides? We give you the necessary freedom.
Rigid tools, rigid slides. The design limitations in die casting are not surprising. As a rule, only open profiles can be produced, which may yield towards the open side under stress.
In contrast, sand casting allows the use of sand cores to create undercuts, which permits maximum design freedom during component development and the production of closed profiles with high rigidity.
Fast and Flexible Implementation
When under pressure, many things slow down. We accelerate implementation.
Ordering steel, building tools, incorporating any changes, producing: In the production of components using the die casting process, up to 40 weeks can pass from order to delivery. This is partly due to the complex manufacturing of large and heavy steel tools.
Thanks to the model equipment made of high-performance plastics used in the sand casting process, series production typically takes only 12 weeks from tool manufacturing to component delivery. This allows the flexibility to react to any changes during component development.
Significant time savings begin as early as the prototype development stage. Since prototypes are almost exclusively produced using the sand casting process, the results can be transferred to later series production almost unchanged. However, if the components are to be produced by die casting later, additional tests will be necessary to verify the new processes which have been selected.
Improved Further Processing
Fine, flexible, perfectly shaped: Those planning big things don’t need pressure.
300 to 1,000 bar. With this immense force, the aluminum material is pressed in the die casting process, almost tearing it apart. This has consequences. For example, if profiles are to be joined by welding during subsequent processing, the trapped air in the form of blisters causes significant problems.
The gentle sand casting process impresses with uniform mold filling and extremely low turbulence. Cooling can be precisely controlled. Subsequent processing by welding is possible without problems.
Economical Production
Our definition of efficiency: Maximum impact without any pressure.
Chained automated processes facilitate fast and highly flexible production. This allows for quick reactions to short-term increased part demand from customers.
Cycle times in die casting tend to be significantly longer due to the extended solidification phase, tool costs considerably higher and steel is expensive. Furthermore, the frequent thermal fatigue cracks in tools due to thermal cycling necessitate frequent, costly tool changes. The plastic models used in the sand casting process can be used up to 60,000 times, depending on the design. Subsequent repair is still possible. Moreover, model modifications, for example during a component facelift, can be carried out without problems.
Technology changes. Our standard remains: highest quality in aluminum sand casting – reliable, precise, leading.
