In the blow moulding process, a fused plastic product matrix is extruded in the form of a vertical tube (parison) which is pressed inside two halves of a mould (manufactured entirely in PLASTIN). This tube is then blown with air to take the inner shape of the mould. It is then subsequently cooled and released in the final form of the container.

For over thirty years, PLASTIN has been using this type of process, ensuring an excellent end product, guaranteed by experience and constant investments. For larger containers, the fused polymer must be extruded very quickly, otherwise it risks “stretching” by effect of gravity. This is called intermittent extrusion, which usually only produces one piece for each machine cycle. PLASTIN also supplies smaller containers using machinery that can reach production of considerable quantities. This allows production of large quantities of containers at competitive prices, thereby supporting industry needs.
