Top 6 Blow Molding Examples by Extrusion Blow Molding Machines

finished products of extrusion blow molding

POSTED SEPTEMBER 2020

There are lots of plastic products produced by extrusion blow molding, which is a manufacturing process that forms hollow plastic parts. In general, there are three main types of blow molding includes extrusion blow molding, injection blow molding (one stage), and injection stretch blow molding (two stages).

Extrusion Blow Molding Process

In the process of extrusion blow molding process (EBM), plastic material is melted and extruded into a hollow tube, and then the parison is formed. This plastic parison is then being closed into a cooled metal mold. Next, the parison is inflated with compressed air, forming the shape of the hollow container or part. After the plastic part is properly cooled, it will be ejected from the open mold.

Products made by extrusion blow molding machines are mostly milk or water bottles, shampoo bottles, automotive air ducts, jerry cans, and hollow industrial preform parts such as drums or other containers.

Extrusion Blow Molding Examples

We categorized the blow-molded parts by their function and application. Here are the top 6 categories of blow-molded products:

Food and Dairy
Water bottles, beverage bottles, and food packaging are made by blow molding machines with high-speed, producing over 2000 bottles per hour. They are the most common plastic molding products in the market.
Households
Blow molding machines can produce household and detergent bottles, laundry bottles, liquid soap plastic bottles, and lotion bottles. Most household products made by blow molding machines are made from materials including PC, PET, PP, and HDPE.
Pharmaceutical / Cosmetics
More and more pharmaceutical, health care, personal care, and cosmetic bottles are manufactured by blow molding machines. A large range of plastic blow-molded bottles and jars is available in sizes from 200ml to 10L.
Lubricants / Petrochemicals
Many lubricants and petrochemical products are stored in blow-molded containers, such as plastic fuel tanks, petrochemical tanks, oil bottles, storage tanks, etc. The multilayered PET containers are often used to store contaminated lubricants and petrochemicals.
Automotive
Blow molding is widely used in the automotive industry, making the mass production of automotive parts simple and cost-effective.
Construction / Gardening / Outdoor Products
Construction barrels, watering pots, and plastic outdoor furniture made by blow molding machines deliver a strong and durable weather-resistant structure.

The Main Differences Between Extrusion Blow Molding and Injection Blow Molding

Process:
The process of extrusion blow moulding involves forming a parison and then blowing. Whereas the process of injection blow moulding involves injection and blowing, then ejecting the final output.
Mold Cost:
The price for extrusion blow molding is lower than injection blow molding.
Production Time:
Production time for the extrusion blow moulding process is slower than the injection moulding process.
Scrap / Flash:
More scraps are produced when using extrusion blow molding machines.
Flexibility of Product Thickness:
The thickness of extrusion blow moulding products can be adjusted, but it is limited in injection moulding.
