The Advantages Of Blow Molding

By Genevive B. Mata


The creation of plastics including a hollow design relies on specific processes to achieve the desired results. Blow molding is a procedure that is implemented in the development of cost effective and efficient production in specific types of plastics. Due to the numerous advantages of using these types of processes, it has become a popular choice for many businesses.

There are three main types of molding processes that are implemented according to the particular need of the company. Extrusion, stretch, and injection molding are the most commonly implemented in large production where the costs are lower and is flexible to be used with many different materials. Most businesses rely on these measures because of the many benefits that it offers for long term results.

Specific procedures are implemented according to the type of product that needs to be manufactured and was developed in 1938. Having become one of the most commonly applied commercial methods, it can be implemented in a variety of applications. Depending on the particular type of product that needs to be developed, the most cost effective solutions are taken into consideration.

The arrival of soft drink bottles in 1977 led to an increase in the demand for such processes and soon the blow mold method became a standard process. It offers a number of advantages including flexibility, fast production, cost effectiveness, and a high level of performance under pressure. The tooling prevents against irregular shape formation and different construction.

An injection blow mold is most commonly implemented in the production of glass and plastic products. The most common being the manufacture of bottles and smaller supplies that need to be delivered in large volumes. The process involves the melting of the polymer that is injected into a mold and then stretched and shaped into the desired outcome.

Completing the stretching procedures will be attended to with preforms that include blowing high volumes of pressure into the specific molds. The use of a core rod will be implemented for the stretching of the preform that can be developed into a variety of shapes and sizes. Such processes can be implemented depending on the company requirements in manufacture.

Extrusion methods are implemented in the creation of dairy bottles, cartons, and even shampoos holders. The advantages include cost savings and efficient production processes when having to meet large order volumes. Blow mold processes remain among the most common applications in manufacture and in the development of art forms.
