A Look At Blow Molding Processes

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.

Molding procedures are based on 3 specific processes that will be determined by the product that is required and the methods of the company. Injection, stretch, and extrusion are common techniques that are implemented where large manufacturing processes are required and the costs need to be kept at a minimum. The different businesses are available and offer numerous benefits for constant and precise production.

These types of procedures have been based on the more traditional applications that were created in 1938 and has since become a core part of commercial measures. With time, these techniques have risen in popularity and applied in different types of processes. The variety of methods are available in the development of specific types of products and is considered most affordable.

In the year 1977, the first bottles were developed for soft drinks and soon the blow mold production process boomed. It includes a wide range of benefits such as flexible operation, cost effectiveness, and production times completed in an efficient manner. The correct tools and systems need to be applied in the developed of the right types of shapes and in the necessary construction.

The injection blow is implemented with both glass and plastic products. The production of bottles and small items will be provided in large volumes. This type of application consists of the polymer being melted and stretched into the specific mold to achieve the solid result in a large volume.

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.
