støbningsteknik

Støbningsteknik, also known as Investment Casting or Wanli Process, is a metal casting technique used to create complex shapes and geometries. The process involves first creating a wax or plastic pattern of the desired shape, which is then coated with a refractory material and invested in a mold. This mold is then burned out and poured with molten metal, which takes the shape of the original wax pattern.

A key characteristic of støbningsteknik is its ability to create intricate and complex shapes with high precision, making it a suitable method for producing objects with small cavities or undercuts. The process is also valuable in the production of components with thin walls or with a near-net-shape finish.

There are several variations of the støbningsteknik process, including the production of ceramic or gel-type shells around the wax pattern, and the use of core rods to create internal cavities or undercuts. Another technique involves using a granular investment material to produce smaller and more complex castings.

Støbningsteknik is widely used in various industries, such as aerospace, biomedical engineering and precision machining. It offers benefits like the capacity for producing castings with relative densities close to that of wrought metal, and high surface finish values without post-processing requirements. However, the technique also presents challenges like material choices, dimensional tolerances, and shell production time. As with any manufacturing process, understanding and managing these factors are essential for realizing the full potential of støbningsteknik.
