Static Pressure Molding
Static Pressure Molding
Precision and High-Density Molding
Static pressure molding (SPM) is an advanced molding method that combines high-pressure airflow with vibration technology to homogeneously compress sand within the mold. This process provides superior dimensional accuracy and smooth surface quality, especially for large-scale and complex castings. In modern foundries, it minimizes casting defects by guaranteeing flawless penetration of sand into the mold cavity.
Working Principle and Technology
These systems create an air shock while filling the mold with sand, ensuring that the sand particles reach even the finest details. Then, the applied static pressure evens out the hardness of the sand at every point in the mold.
Advantages of Static Pressure Molding Systems
Key benefits that will improve your business's production quality:
High Mold Density and Surface Quality: Thanks to the even compaction of sand at every point, no roughness (pitting, etc.) occurs on the casting surface; the need for cleaning (grinding) is reduced.
Excellent Dimensional Accuracy: Eliminates the risk of expansion or slippage in the mold, ensuring parts are 100% faithful to the technical drawing.
Ideal for Large and Heavy Castings: Thanks to its high pressure capacity, it offers unparalleled stability in molding large-volume parts.
Reduced Mold Defects: Minimizes chronic molding defects such as air gaps or incomplete filling.
Short Cycle Times: Automated processes maximize efficiency by increasing the number of molds produced per unit of time.
Full Automation Compatibility: Easily integrated into intelligent casting lines (Industry 4.0); eliminates operator errors.
