Blow Molding Concept And Its Different Applications

Blow Molding Concept and Its Different Applications

A blow mold may be formed from a hollow plastic. It goes into a series of processes including that of the this website production of hollow materials from a material known as thermoplastic. It has three main types namely the extrusion, injection and stretch blow moldings. The whole process starts when a piece of plastic with a hole in either ends are melted. The hole is where the air passes through to form a blow mold.

Newest blow mold applications

While blow molds underwent a series of changes in history, certain technologies were instituted to improve the output. Now, new applications are being set in the blow molding industry. The most common examples include:

Coextrusion blow molding. This usually involves large parts and is commonly used in the production of containers and small bottles. This will this website soon be recognized in the market especially now that there is a need to recycle plastic.

Three-dimensional blow molding. This type of blow mold started click here in Japan and is capable of producing different shapes and sizes from a plastic material.

Hard-soft hard or soft-hard-soft technology. In this new application, users are entitled to choose different materials aside from depending on plastic.

Other pertinent facts on a blow mold

The best way to start a project involving the use of a blow mold is to consider the different characteristics of the polymer material. For instance, if one is considering a high-density polyethylene, it means that there is low temperature strength, excellent chemical resistance and ideal insulating capacities in the material. For a choice of polycarbonate, one will be able to acquire great resistance from heat, excellent transparency and a hard and tough material.

To complete a blow mold job, different types of equipment or machinery are also being used. This may range from the single stage blow molding machine to the modern automatic PET blow molding machines. The most common outputs from this process are milk bottles, one-piece chair, garbage cans, drums and fuel tanks.
