Rubber is a versatile material that has plenty of applications across a number of industries. And it is up to the manufacturers to come up with best quality that adds value to the processes of these concerns. The way they process and produce rubber makes all the difference. Rubber can be shaped into the desired article using a few ways. Extrusion and molding are the two most common options that manufacturers use.

Top manufacturers that take quality seriously know which process is better for what kind of product. They use state of the art technology and advanced machinery to produce high quality products for their customers.

Advantages of Extrusion

Extrusion and molding both have their respective advantages. Here we will discuss some of the advantages for extrusion.

The Material Produced Is Durable

Rubber produced through extrusion is hardy and long lasting. The combination of flawless material and expert knowledge results in premium product that works well and retains its excellent condition over a long time.

The Products are Cost Effective

The product made using extrusion techniques is usually cost effective, and as there is less wastage, the yield is higher. A knowledgeable manufacturer ensures that the product is made at optimum costs without compromising quality.

Using Rubber Extrusion Techniques Can Produce Complex Shapes

Extrusion due to its simple yet effective technique can produce complex shapes, as extrusion die can be created with any shape to adjust the customer’s needs. Continuous and long shapes can be produced using this technique.

Extrusion Is Ideal for Making Hoses and Pipes

Rubber extrusion can make pipes and hoses of varying shapes and properties to accommodate different needs. The ability to make products which can be as long as 60 feet is perfect for the pipe manufacturing industry.

Different Types of Rubber Can Be Used

Rubber extrusion can use different types of rubber of varying properties. This can result in a huge variety of products that can be made.

How Rubber Extrusion Works

The extrusion method uses a die, which is like a disk, with a shape cut out according to the cross-section of the end-product. This precise tool is made according to the customer’s requirement. The die is carefully designed to adjust during the later stages when the product may experience change due to further treatment. Rubber tends to increase or decrease in size due to the further processes it undergoes.

The extruder pushes the soft, un-vulcanized rubber through the die. The rubber is forced to adjust the shape in accordance to the prescribed shape on the die. The rubber is then further treated according to the requirements. Any other modifications like; drilling, punching or cutting are performed on the product. Finally, a high quality product is delivered to the customer.

To ensure that you are always delivered premium quality product that fulfills the specifications and is according to standards, you should always look for reliable and professional manufacturers like Sperry & Rice.
