puhallusmuotoprosessien
Puhallusmuotoprosessien, or blow molding processes, are a manufacturing technique used to produce hollow plastic parts. The fundamental principle involves heating a thermoplastic polymer tube, known as a parison, and then inflating it by blowing air into it while it is enclosed within a mold. The pressurized air forces the softened plastic to expand and conform to the inner contours of the mold. Once the plastic cools and solidifies, the mold opens, and the finished hollow part is ejected.
There are several variations of blow molding. Extrusion blow molding is the most common, where the parison
This process is widely used for manufacturing a diverse range of products, including beverage bottles, containers
