The Main Advantages of Extrusion Blow Moulding

Extrusion blow moulding is a manufacturing process used to make hollow plastic parts. It is a cost-effective and versatile process.

It is a plastic molding technique that forms hollow bottles, containers and tubes. It can also be used to make products that require a complex shape.

1. It is a cost-effective process

Extrusion Blow Moulding is a cost-effective process that is widely used in the production of plastic products. It is also a versatile method that allows for a wide range of shapes and sizes.

To start the process, raw plastic material is heated to a certain temperature like in jwell 200L drums blow molding machine before being poured into a parison (a hollow tube). Then, it is pumped into a mold that’s been prepared.

The main advantages of Extrusion Blow Moulding are its ability to produce complex parts and products quickly and accurately. It also promotes a high level of productivity.

However, this method relies on millions of gallons of petroleum and contributes to the depletion of the world’s oil supply. It’s also not biodegradable, so it has a negative environmental impact.

It’s important to understand the difference between the two methods so you can choose the best one for your company. The key is to consider the type of product you’re producing, your budget and what your goals are for your product.

2. It is a versatile process

Extrusion Blow Moulding is a versatile process that can create a wide range of plastic parts. It can be used for manufacturing bottles, jars, tubing, containers, and other hollow parts.

The process begins with a plastic feedstock that is fed through an extruder and melted to plasticise the material. This then flows through an especially designed blow molding die that directs the flow of material to form a tube known as a parison.

Once the parison reaches a desired length, it is captured between two mold halves that close around it. The mating surfaces pinch together the open areas of the parison and high pressure air is introduced into it to expand it to the shape of the mold.

This process is ideal for creating hollow plastic parts that are lightweight, durable, and resist rust. It is used to produce automotive parts, lawn equipment, and pet toys among others.

3. It is a recyclable process

Extrusion Blow Moulding is a type of plastic forming process where an extruded plastic tube (a parison) is inflated with air inside a mold to form the final product. It is commonly used for the production of hollow plastic bottles, canisters and other containers.

The resin is melted and extruded into a tube-like piece called a parison with jwell PET sheet extrusion line, which is then closed into a two-part metal mold. After the parison has been shaped, compressed air is pumped into it, inflating it to match the shape of the mold.

In this process, it is important to ensure the quality of the product produced. Good parison control can improve product quality, reduce energy use and help with the overall cost of the blow moulding process.

It is also possible to recycle waste in the form of pinched off parison material and trimmed flash during the blowing step of the process, which is carried out at the end of the moulding cycle. The resulting waste can be granulated and fed back into the raw material stream feeding the extruder for reprocessing to make single material parts.

4. It is a renewable process

Extrusion Blow Moulding (EBM) is a process that uses melted plastic to create hollow bottles, containers, and parts. It is used to produce a wide range of plastic products, including water bottles, peanut butter jars, specimen jars, and more.

EBM is a renewable process that requires less energy with jwell plastic sheet extruder and is also environmentally friendly. It is a versatile and cost-effective manufacturing method that allows manufacturers to produce a wide range of finished plastic products.

Unlike injection blow moulding, extrusion blow moulding is not a process that requires a metal shank or core rod to capture the precursor material, called a parison, which makes it an ideal alternative for biodegradable materials.

The main advantages of extrusion blow moulding include its ability to produce a wide variety of plastic products, lower pressure required for molds, and lower machine costs. It is also a cost-effective method for producing heat-sensitive plastics, like PVC. Moreover, it can produce high-quality bottles and jars with excellent visual and dimensional qualities.
