The blow mold may be formed of a hollow plastic. It enters a series of processes, including the process referred to a thermoplastic material from hollow material production. It has three main types, namely extrusion, injection molding and stretch blow molding. The whole process from beginning to melt the plastic with holes at both ends. Where holes are formed by blow-molding air.
The latest blow mold applications
In the blow mold has experienced a series of historical change at the same time, some people are using technology to improve productivity. Now, the industry is setting up a new blow molding applications. The most common examples include:
Coextrusion blow. This usually involves large parts, commonly used to produce containers and vials. This will soon be recognized in the market, especially now need to recycle plastics.
Three-dimensional blow. This began in Japan blow mold, the blow mold to produce different shapes and sizes of plastic.
Hard-hard and soft or hard and soft technology soft technology. In this new application, users have the right to select a different plastics material.
Other relevant facts on the blow mold
The best way to start the project relates to the use of the blow mold is to consider the different characteristics of polymeric material. For example, if we consider the use of high-density polyethylene, it means that the material has a low strength, excellent chemical resistance and desired insulation capability. Polycarbonate choice, it will be possible to obtain good heat resistance, excellent transparency and rigid material.
The blow mold in order to complete the work, but also the use of different types of equipment or machinery. Range from a single-stage blow molding machine to modern automatic PET blow molding machine. The most common output of this process is a bottle, a one-piece chair, garbage cans, drums and fuel tanks.
