What is an Extrusion Molding Machine?
The extrusion blow molding machine is to use the wind blowing from the machine to blow the plastic body to a certain shape of the mold cavity after spraying out the liquid plastic, so as to make a product. This kind of machine is called a blow molding machine. The plastic is melted and quantitatively extruded in a screw extruder, then formed by a die, and then cooled by an air ring, and then pulled by a tractor at a certain speed, and a coiler winds it into a roll.
Common Extrusion Blow Molding Machine Types
Extrusion blow molding machines can be divided into two categories: continuous extrusion blow molding and batch extrusion blow molding machines. In continuous blow molding, the plastic is continuously extruded while the machine is running. For batch extrusion blow molding, the extruder runs for a specified time and fills the container with plastic; after the tank is filled, a plunger is activated and pushes material from the tank through the extrusion head.
EBM machines can be used to make a variety of bottles, containers and shapes that are commonly used to make products that we use in our daily lives, such as oil bottles, peroxide bottles, shampoos, and personal care products.
Batch EBM machines are often used to make large parts or products that require thick walls, such as 5-gallon water coolers and gasoline containers.
What Are the Characteristics of an Extrusion Molding Machine?
Advantages
Revolutionary – The extrusion method of creating plastic products revolutionized manufacturing technology, giving different industries a viable solution.
Output – With high-volume output, this machine can produce a vast number of finished bottles and containers.
Diversity – A machine used for extrusion blow molding can produce a variety of products used by food and beverage, medical, manufacturing, pharmaceutical, and other industries. The ability to produce products for diverse applications makes this process highly advantageous to others.
Low Cost – Thanks to advances in machines used for this process, it costs manufacturers less to produce stellar products. For one thing, newer machines require less energy. Also, using a low level of pressure helps lower the cost of the machinery and its operations.
Automation – Now as an automated method of production, the amount of wasted polymer is less. Also, automation increases productivity and ensures greater precision.
Disadvantages
Petroleum Dependency – Machines used for extrusion blow molding as a means to produce plastic products require a significant amount of petroleum, threatening to diminish the oil supply.
Limited Capability – This type of machine produces hollow plastic bottles and containers. Although widely used by multiple industries, there are some limitations.
Environmental Impact – In addition to the fact that this machining process depends on millions of gallons of petroleum, it produces plastic, which is a non-biodegradable material. For those two reasons, the process has a negative impact on the environment.
The Main Application of Extrusion Molding Machine
The extrusion blow molding process has become very common in manufacturing, let's look at some industries and pay attention to the products and parts they use every day.
-
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 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.
-
Medical supplies and parts – If you’ve been to a health clinic, your dentist, or to visit your family doctor you can quickly start counting how many hollow containers are used. Spray bottles, water bottles, and storage containers line the cabinets. All of those are quickly made with blow molding.
-
Children’s toys – If you have a small child, you could quickly count how many hollow lightweight toys they have. Blocks and squeeze toys are common uses for blow molding.
-
Lawn and garden items – You could almost put lawn and garden into the automotive and bulk container categories as it uses bottles for liquid products and uses blow molding for mowers and power equipment for fuel tanks, oil storage and distribution.
-
Marine – Products that go in the water need to be buoyant, and blow molding makes hollow products with ease. Reservoirs, buoys, and other items are commonly made with blow molding.
-
Packaging – Customized packaging with Polystyrene keep products safe, and blow molding makes hard to create shapes with ease.
-
Sporting Goods – A common blow molded product in sporting goods is a plastic bat, a plastic ball, or another hollow piece of equipment.
-
Industrial bulk containers – Think of larger fluid containers like barrels to transport and store water, oil, or anything else liquid. Those are made with blow molding.
