Støbetype

Støbetype refers to the specific method or process used in casting to create a shaped object from molten material. The choice of støbetype is critical as it influences the final product's shape, accuracy, surface finish, mechanical properties, and production cost. Various støbetypers exist, each suited for different materials, production volumes, and design complexities.

Common støbetypers include sand casting, which uses a mold made from sand, suitable for large and complex shapes, often used for ferrous metals. Investment casting, also known as lost-wax casting, produces highly detailed and intricate parts with excellent surface finish, ideal for aerospace and jewelry. Die casting involves forcing molten metal into a reusable mold cavity under high pressure, offering high production rates and good accuracy for non-ferrous metals. Permanent mold casting utilizes reusable metal molds, providing better surface finish and dimensional accuracy than sand casting, often used for aluminum and magnesium alloys. Shell molding uses a mixture of sand and resin cured to form a shell mold, offering good accuracy and surface finish for medium to large production runs. Centrifugal casting involves spinning a mold while molten material is poured in, resulting in dense, uniform castings with good mechanical properties, often used for pipes and cylinders. The selection of the appropriate støbetype depends on factors such as the material being cast, the required tolerances, the desired surface quality, the complexity of the design, and the intended production volume.
