How Is Plastic Extrusion Useful?

If your business needs to create custom parts for your products, plastic extrusion is a good solution. This manufacturing process helps businesses in many industries create a high volume of uniform components. At Clark Rubber and Plastic, we offer custom plastic extrusion services. Here’s more information about the extrusion processes and what makes it useful:

Plastic Extrusion

Extruded plastic is formed by placing polymers into a heated chamber. The high heat melts the plastic to create a smooth, moldable material. Melted plastic moves into a mold, where it is forced into a unique shape. Once the plastic is extruded, manufacturers allow it to cool fully before cutting it to size and preparing it for transport. This helps the product maintain its intended shape during use.

Product Uniformity

During the plastic extrusion process, manufacturers filter the melted polymer to remove any impurities or contaminants that could weaken the final product. This careful preparation results in a large number of high-quality plastic parts with the same structural makeup. The die molds also promote uniformity as each batch of extruded plastic will match the custom shape and size of the mold.

Production Speed

One benefit of the extrusion process is the ability to create many identical parts in a short amount of time. Automated extrusion machinery makes the manufacturing process more efficient and saves companies time and effort. Manufacturers program automated equipment to perform repetitive tasks with consistent results. Once the manufacturer has a digital design for the intended product, they can enter the measurements into the system and instruct it to fulfill specific production volumes. Computer numerical control, or CNC, systems speed up the design and fulfillment processes of extrusion projects. 

Project Customization

Plastic products can be customized by creating unique extrusion molds, choosing specific polymer types, and adding colorants. Die molds are produced by fabricating metal into profiles that match the plastic product’s intended dimensions. Many types of plastic can be melted and used in these dies, including polyethylene, polypropylene, and polyvinyl chloride. Our team of manufacturers will recommend a plastic type that matches your final product’s application. This will help improve the durability and efficiency of the plastic parts.

If you want your components to have a specific color, we can mix colorants with the raw plastic before the melting process. This allows the materials to blend together as they melt, creating a consistent color for each plastic part. If you need a fully customized component, work with our team to create a die mold. Customized molds enable companies to produce parts that are tailored to different applications across various industries.

What is Rubber and Plastic Extrusion?

Extrusion molding can be used to make pipes and tubing, tracks, hoses, and drinking straws. Clark Rubber and Plastic offers two versatile material options for extrusion molding. Learn more about rubber and plastic extrusion, which options are right for your project, and how to use extrusion services:

Extrusion Process

Extrusion molding is a manufacturing process where a material is softened or melted and then pushed through a mold. After it cools, the shaped material is cut to the desired length for the final product. This type of molding works well with high-volume production and for tube-shaped items like rods, siding, or weather stripping. Clark Rubber and Plastic provides plastic and rubber extrusion services with cutting-edge technology for high-quality results.  

Rubber Extrusion 

Rubber extrusion is when rubber material is used in the extrusion process and molded into the desired shape. This is often used for products like weather strips and gaskets. Unvulcanized rubber is loaded into the extruder and forced through the shaped die under high pressure. The rubber takes on the shape of the die and is then vulcanized to harden it and add durability. Different types of rubber are used depending on the product’s requirements. Clark Rubber and Plastic has a facility set up to use natural rubber, neoprene, nitrile, and other rubber materials. Rubber-extruded products can be recycled at the end of their useful life, reducing waste. 

Plastic Extrusion 

The plastic extrusion process takes melted plastic and pressurizes it through a die. The extruded shape is then cooled with cooling rolls or water baths to solidify the product. Plastic extrusion is a versatile, high-volume manufacturing process that is suitable for pipes, fencing, deck rails, or window frames. The raw materials for plastic extrusion are typically plastic pellets that are loaded into a hopper. Additional additives like fillers and coloring are then added before the material is moved forward, heated, and shaped. Clark Rubber and Plastic’s extrusion services can produce a range of shapes, sizes, thicknesses, and hardness to fit your needs. 

Differences Between Plastic and Rubber Extrusion 

Plastic and rubber extrusion have a similar process but have final results with different properties. Rubber extrusion creates more flexible products with elasticity, even after the product has been cooled in the final stage. Products from plastic extrusion are rigid and may become deformed if you try to stretch them. Plastic is extruded at a higher temperature than rubber. Products from plastic extrusion are found in the solar, construction, automotive, and medical industries. Rubber-extruded products are used in appliances and electrical work. 

Extrusion Services From Clark Rubber and Plastic 

Extrusion molding is a flexible production option that often saves time and costs because the final product doesn’t always require post-production finishing. The continuous process allows a large amount of parts to be created quickly without requiring the multiple-step drafting process of other molding options. Extrusion also has some sustainable properties since the discarded material can be reused, and the finished items are often recyclable.

How Does Plastic Extrusion Work?

Plastic extrusion involves melting plastic into solid, finished products such as pipes and tubing. Understanding how extrusion methods work helps determine which technique fills a business’s needs. Some processes include co or tri-extending, which can produce a wide variety of shapes, forms, and textures. At Clark Rubber and Plastic, we provide plastic extrusion services for products used in various industries. Here’s how our process works:

Heating 

Our team at Clark Rubber and Plastic uses various types of plastic for extruding, including PVC, acrylic, and TPU. We start the process by heating the materials to create a specific product for a business’s needs, whether it’s automotive or solar parts. Our manufacturers may also add colorants or stabilizers to the melted mixture to enhance its final quality.

Heating occurs as the plastic pellets fed into the melting chamber are pulled along by a revolving screw. The friction caused by the movement increases the pressure and generates heat, leading to melting. A filter screen sits at the end of the melting chamber, which removes impurities from the melted plastic as it is pushed through.

Shaping 

The melted plastic is pushed out of the barrel chamber through a die, which sets the final shape of the extruded product. Some common plastic products created through extruding include bars, pipes, wire insulation, and monofilaments. Plastic extrusion also creates products with custom profile features like edges and channels. Co- and tri-extruding can create items made with different components or incorporating different colors. In both processes, the materials composing the outer layers are of high quality to help the finished product be more stable.

Some shrinkage can occur during the extruding process and is more common with complex profiles. Designers may overcome this by being generous when sizing a die, allowing a small amount of extra space in the mold to account for shrinkage. Additional shearing can be done later on the production line to maintain uniform sizing.

Cooling

The shaped plastic profile is set through cooling, finalizing the product’s form. This process happens as belts pull the profile through a long trough containing a cold water bath. Certain products, such as plastic pipes, might require additional mechanisms that remove heat in order to keep their shape. Designers may apply a vacuum to the water bath to keep the pipe from collapsing as it cools.

The belts pulling the profile along also help to correctly size the cooled profile, satisfying the client’s required dimensions. The sizing belt pulls the profile through a final opening, at the end of which a blade slices it into individual pieces. These are the completed products that are then sent on to users.

Different Plastic Extrusion Techniques

Plastic extrusion is a high-volume manufacturing process that involves pushing melted plastic through a die so that the plastic takes on a new shape. This process can create a wide range of plastic products with various shapes, profiles, sizes, and properties. It is also highly customizable and cost-effective, making it a good option for large-scale production runs and custom projects. There are multiple plastic extrusion techniques used for different applications, including: 

Co-extrusion

Co-extrusion combines two materials with different properties into a single cross-section. The process uses two extruders to extrude multiple layers of material simultaneously. These extruders can be set to different speeds and sizes to alter the layer thicknesses. Our manufacturers use co-extrusion to produce products with various performance characteristics, including enhanced durability and strength.

Clark Rubber and Plastic can also complete projects that require tri-extrusion. Tri-exclusion is similar to co-extrusion but uses three extruders and separate materials. This allows our manufacturers to customize your product to your desired specifications.

Tubing Extrusion

We use tubing extrusion to produce plastic tubes and pipes with uniform dimensions and properties. This process often requires the extruder to push a positive internal pressure throughout the plastic to create a hollow core. Tubing extrusion can create pipes for medical devices and plumbing applications because it produces tubes with precise tolerances, smooth surfaces, and consistent quality.

Blow Film Extrusion

Our manufacturers use blow film extrusion to produce thin plastic films with uniform thickness, such as shopping bags and food packaging. The melted plastic is extruded through a circular die to create a tube during the extrusion process. The machine then uses air pressure to inflate the tube to the desired size and thickness. We can customize these specifications to fit the diverse needs of various industries and applications. 

Sheet Extrusion

The sheet/film extrusion method produces flat plastic sheets of varying thicknesses. It may be used to produce plastic films or sheets that are too thick to be made with blow film extrusion. During extrusion, molten plastic is extruded through a flat die, which is then cooled to form a continuous sheet. Sometimes, the sheets go through a series of cooling rolls, which can control sheet thickness. We use these sheets to create various products, including signs or packaging materials. 

Over-Jacketing Extrusion

Our manufacturers use over-jacketing extrusion to apply an additional protective coating to something, most often a cable or wire. In this method, the machine extrudes a layer of melted plastic material over the surface of the cable. This helps provide enhanced insulation and durability, increasing the wire’s reliability and safety.
