Both injection blow molding and extrusion blow molding processes are integral in many manufacturing applications. These techniques are used to create many disposable and recyclable plastic parts, including products used in medical and research applications. Both processes feature unique functions to produce different results, which is why it&#;s important to understand each process to determine which is suitable for manufacturing a particular product. To help you better understand the differences between injection blow molding and extrusion blow molding, we&#;ll go over how each process works so that you can determine which is best for your needs.

To increase production efficiency in the s, injection molding was developed. The process involves melting plastic and then injecting it into a predesigned mold. Primary advantages of injection molding include reduced waste, minimal finishing requirements, and recyclability. Unlike extrusion molding, the design capabilities of injection molding allow for the manufacturing of 3D components. The machines used for injection molding include two core components: the clamping unit and the injection unit. Injection blow molding, or IBM, is a specific type of injection molding process that involves the use of a metal shank or core rod. The process uses a parison that forms the basis for the finished product. The beginning of the IBM process entails transferring the parison/core rod into the blow molding unit of the machine, followed by inflating and cooling the pre-formed part. After cooling, the core rod is rotated to the ejection position, the mold is opened, and the product is removed. Throughout the process, three sets of core rods are used to facilitate mold injection, blow molding, and the ejection of the formed part.
Extrusion blow molding, or EBM, is similar to IBM, but instead of injecting melted plastic into a mold, the material is extruded or expelled into a hollow tube, known as a parison. A mold closes around the parison in order to shape the part while at the blow station. At the blow station, air is blown into the parison inflating it into the shape of the mold. Once the plastic has cooled, the mold is opened, and the part is extruded. Any excess material is trimmed from the completed part. Because of the EBM process, there is typically a high level of scrap produced.
There are three main areas in which injection blow molding and extrusion blow molding differ.
The principal difference between IBM and EBM is the type of products they create. IBM is typically used to form more solid parts, which can include medical parts, kitchen parts, and other solid components. Meanwhile, EBM is used for manufacturing more hollow parts like bottles and other containers. Extrusion Blow Molding can manufacture more complex shapes due to how the product is formed. However, injection molding is able to produce large volumes of quality parts quickly and accurately.
For IBM, there needs to be a high precision match between both halves of the mold to enable total control over the flow of resin. Most of the work involved in injection molding involves producing the mold. In EBM, there is a higher level of design flexibility between both mold halves since each half forms its own wall shape.

Blow moulding is a manufacturing process for forming and joining together hollow plastic parts. In general, there are three main types of blow moulding: extrusion blow moulding, injection blow moulding (one stage), and injection stretch blow moulding (two stages). In the extrusion blow moulding process (EBM), plastic is melted and extruded into a hollow tube (a plastic parison). This plastic parison is then captured by closing it into a cooled metal mould. Air is then blown into the parison, inflating it into the shape of the hollow bottle, container, or part. After the plastic has cooled sufficiently, the mould is opened and the part is ejected. It is designed to manufacture high volume hollow plastic products.
Most PE hollow products are made by Extrusion Blow Molding Machines like milk or water bottles, shampoo bottles, automotive air ducts, jerry cans, and hollow industrial perform parts such as plastic drums or other plastic containers.
The most common needs of humans are kept in these plastics containers. Water bottles, beverage bottles, sauce, milk, food packaging and what not! These are the common products made by Blow Molding Machines with high-speed capacities of over pcs bottles per hour.

Blow Molding Machines can produce household containers like hair oil, detergent bottles, laundry bottles, liquid soap plastic bottles containers and lotion bottles. Most of them are made from a wide range of materials including PC, PET, PP and HDPE.
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. A large range of refined and essential designed plastic blow-moulded bottles and jars are available from size from 200ml to 10L.
Many lubricants and petrochemical products are stored in blow-moulded containers. Containers such as plastic fuel tanks, petrochemicals tanks, oil bottles, storage tanks, etc. They often use multilayered PET to store contaminated lubricants and petrochemicals.
Customized shapes with Polystyrene keep products safe, and blow moulding makes the hard to create shapes with ease. Blow moulding is widely used in the automotive industry and makes the design and mass production of automotive parts simple and cost-effective. Many of the parts storing fluids use blow moulding. Cooling system overflow containers, windshield washer fluid bottles, and even fuel tanks are commonly made with blow moulding.
Did someone say cosmetic? well, people who do make-up know about it all, whether it be foundation or cream to make you glow, its bottles are manufactures in Extrusion Blow Moulding. Other than that health care and personal care bottles are also manufactured by Blow Molding Machine.
Where do you store litres and litres of water or oil in your home and factory respectively? Well, think of larger fluid containers like barrels to transport or store water, oil, or anything other liquid, those are manufactured by Blow Moulding.
Sometimes in science labs, you must have noticed plastic flasks to keep chemicals or measuring cylinders/tubes made out of plastic which is manufactured in Blow Moulding. The commonly manufactured bottle is for pesticides.
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 moulding. A common blow moulded product in sporting goods is a plastic bat, a plastic ball, or another hollow piece of equipment.
Products that go in the water need to be buoyant, and blow moulding makes hollow products with ease. Float cubes, buoys, fish netballs and other items are commonly made with blow moulding.
