What products are manufactured using blow Moulding?

Everyday hollow plastic objects like milk cartons, shampoo bottles, storage drums and watering cans all have a specific manufacturing process in common – blow moulding.

What is blow molding used for?

Blow molding (or moulding) is a manufacturing process for forming and joining together hollow plastic parts. It is also used for forming glass bottles or other hollow shapes.

What is the most common type of blow molding process?

Extrusion Blow Molding
Extrusion Blow Molding Perhaps the most common type of blow molding process is extrusion.

What is the blow molding process?

Blow molding is the forming of a hollow object by inflating or blowing a thermoplastic molten tube called a “parison” in the shape of a mold cavity. The process consists of extruding or “dropping” a parison on which female mold halves are closed. The female mold halves contain the shape of the product to be produced.

What is extrusion blow molding process?

Extrusion Blow Molding is the simplest type of blow molding. A hot tube of plastic material, called a parison, is dropped from an extruder and captured in a water cooled mold. Once the molds are closed, air is injected through the top or the neck of the container; just as if one were blowing up a balloon.

What is blow molding process?

What is blow Moulding in engineering?

Updated Monday, 20th November 2017. A process for forming plastic, thin walled, hollow containers such as bottles. Raw thermoplastic in the form of pellets, or granules, is melted and extruded to make parison tubes.

What type of plastic is used in blow molding?

Blow Molding Materials In addition to HDPE blow molding, some of our most commonly recommended and requested materials and finishes include: Polypropylene (PP) Polyethylene (HDPE, MDPE, LDPE) Nylon (PA)

Which of the following plastic is used in blow molding?

High Density Polyethylene (HDPE) HDPE is the world’s #1 plastic and the most commonly blow molded plastic material. It’s used in a vast array of products, including bottles for consumer liquids such as shampoo and motor oil, coolers, play structures, fuel tanks, industrial drums, and carrying cases.

What are the four kinds of blow molding processes?

The Blow Molding Process

• Injection Blow Molding. In injection blow molding, a blow or core rod is used throughout the process.
• Extrusion Blow Molding. Extrusion blow molding can be continuous or intermittent.
• Injection Stretch Blow Molding.

What is a blow molding machine?

With blow molding, a machine blows air across heated plastic that’s placed on top of a mold cavity. The air forces the heated plastic to expand across the interior walls of the mold cavity.

How does a blow molding machine work?

The process involves heating a plastic tube (known as a preform or parison) to its melting point and then putting that into the cavity of a mold. They then use compressed air to inflate the molten plastic like a balloon so that it takes the shape of the mold but is hollow inside.

What is blow molding used to make?

Developed in the late 1930s, blow molding is a manufacturing process that is used to form hollow plastic parts. It is most commonly used to make plastic bottles. In principal, the basic blow molding process is similar to glassblowing. Plastic resin (pelletized raw plastic material) is melted…

What is the difference between extrusion blow molding and injection molding?

Extrusion Blow Molding (EBM) is commonly used to make bottles, industrial containers, automotive products, appliance components, and children’ toys. Injection Blow Molding (IBM) is normally used to make smaller bottles (usually smaller than 16oz / 500ml in volume) with high production volumes.

What are some examples of blow molding in the auto industry?

Automotive industry: Many of the parts storing fluids use blow molding. Cooling system overflow containers, windshield washer fluid bottles, and even fuel tanks are commonly made with this process.

What are the different types of appliances that use blow molding?

Cooling system overflow containers, windshield washer fluid bottles, and even fuel tanks are commonly made with blow molding. Appliance components – Your major appliances at home include reservoirs that contain fluids and help to wash your clothes and dishes. These are commonly made via blow molding.
