Blow molding, is a process used to manufacture hollow plastic parts, trough the expansion of the material. This is make by pressure air on the walls of the preform, whether it is injection-blowing; or the parison, if it is extrusion-blowing.

Blow molding is a continuous or discontinuous process of producing hollow thin-walled parts from thermoplastic materials. For example: bottles and containers. The two main types of blowing are by injection and by extrusion.

The blow molding, is a blowing process in which the preform is a tubular sleeve, formed by extrusion, called a preform, which is closed by the lower part in a hermetic way due to the clamping exerted by the mold parts when closing. Then it is blown, allowed to cool and the part is ejected.

We have experience in blowing extrusion of engineering plastics like; LDPE, HDPE, PVC-U, PS, PP, etc. Developing solutions for the Automotive and Electrical sector mainly. 

In MADISAYM We offer service of Extrusion-blowing plastic with machines up to 2 liters of capacity in volume.

Currently in our facilities we can support to you from the tooling, until manufacturing finish good parts. We elaborate prototypes, tests, etc.

Plastic Blowing, can give you a solution to your need.
