FROM THE IDEA TO THE FINISHED CAST PART

Product catalog summary

Overview of Sand Casting Process:

The document outlines the sand casting process for metal casting, emphasizing the use of large-format sand molds. The process is detailed in several steps, starting from the CAD model to the finished casting.

Key Steps in the Process:

CAD Model: The process begins with the creation of a CAD model, which serves as the blueprint for the sand mold.
Sand Mold Creation: The sand mold is created to match the CAD model exactly, allowing for precise casting without the need for draft angles or undercuts.
Integrated Gating System: This system is incorporated into the mold to facilitate the flow of molten metal.
Embedding and Pouring: The sand mold is embedded, and aluminum is poured into it.
Demolding and Cooling: After pouring, the mold is demolded, and the casting is allowed to cool.
Lost Sand Mold and Finished Casting: The sand mold is lost in the process, resulting in the finished casting.

Specifications and Advantages:

Mold Measurements: Molds can be as large as 4 x 2 x 1 meters.
Efficiency: The process eliminates the need for elaborate mold setups and allows for short throughput times of just a few days.
Design Flexibility: Structures can be designed according to specific requirements without additional costs for changes in geometry.
Material and Surface Quality: Special sands are used to prevent casting problems, and surface quality can be adjusted by using different sands. Coarse-grained sands are used for high gas permeability.
Cost Savings: Significant cost savings are achieved, especially for complex molds and batch sizes ranging from one to several hundred pieces.
