keskusvalumenetelmä

The term "keskusvalumenetelmä" translates from Finnish to English as "central casting method." This refers to a manufacturing process where a mold is centrally filled with molten material. The core principle involves introducing the casting material, often metal or plastic, into a single, central point of the mold cavity. Gravity or pressure then forces the material to flow outwards from this central gate towards the mold's extremities.

This method is commonly employed in various industries, particularly in the production of components with relatively simple geometries and uniform wall thicknesses. Its advantages include a more uniform filling of the mold, potentially reducing stress concentrations and improving the structural integrity of the final product. The central gate can also simplify the mold design and runner system compared to methods with multiple gates.

However, the effectiveness of the central casting method is dependent on factors such as the viscosity of the molten material, the design of the mold, and the temperature control during the casting process. If not properly managed, issues like incomplete filling, trapped air, or uneven cooling can arise. Despite these considerations, the keskusvalumenetelmä remains a valuable technique for achieving consistent and reliable casting results in many industrial applications.
