Extrusion blow molding machines can produce a wide variety of hollow plastic products. It is important to keep in mind that in order to produce exceptional products, besides purchasing high-quality Blow Molding Machines, it is also crucial to choose the correct blow molding material for each project. This ensures that the end products will have the desired properties and will also be able to withstand the environment(s) that they will be exposed to.

One thing that makes blow molding so great are its endless applications. In fact, plastic products are everywhere, making it clear how incredibly useful this material is in modern life. However, in today’s world, the production of these products is not just a matter of their unit price, quality, or visual appearance; customers and end users also care about their sustainability, and they care a lot.

HDPE Blow Molding is the most economical- highest production output forming process for hollow products: beverage, chemical or pharmaceutical bottles, edible oil jerry cans, chemical drums, etc. And even though you can produce an almost perfect, high quality container, you might encounter different problems along the blow molding process of your products, so it is vital that you can identify where the problem comes from and how to handle it.

What is HDPE Blow Molding? HDPE Blow Molding is the process of molding a softened thermoplastic hollow form called a Parison. This Parison is first vertically extruded from the Die Head of a Blow Molding Machine and then, it is inflated against the cooled surface of a closed mold, the expanded plastic then solidifies into a hollow HDPE product that needs none or very little finishing processes after the Blow Molding.

Blow Molding machines have many advantages when it comes to making hollow plastic products, and especially for large hollow plastic products they are really your best solution. As an example, one very popular and common application of Blow Moulding for large products is the molding of Paddle Wheel Aerator Floats and Gear Box Covers for Aquaculture; these floats are used in Fish Farming to hold the Paddle Aerators Wheels that give the fish the oxygen they need from the environment for respiration.
