  1. Plastics Manufacturing from Concept to Production to Storage

    Leave a Comment

    When it comes to plastics manufacturing, extrusions are one of the most efficient means of producing components with continuous shapes, including tubes, pipes, profiles, and rods. The process uses heat and pressure to form shaved plastic into components of varying colors, textures, and sizes, and that have a range of physical and chemical properties. The tooling that enables such versatility is also economical, offering substantial cost-savings for high-volume production.

    At Applied Plastics, we specialize in custom tooling and extrusion processes using a variety of plastic materials. Our combined focus on both tooling and production allows us to achieve competitive lead times, all while keeping costs low and quality high.

    steps to the plastic extrusions process

    A Guide to Plastics Design and Manufacturing

    The plastic extrusion process is simple, fast, and cost-effective, although manufacturers must pay attention to some key constraints during the design process.


    As when designing any component for plastics manufacturing, engineers should begin the extrusion design process by considering the application’s constraints. For instance:

    • Will the component be exposed to adverse conditions? If so, how often and what kinds?
    • Where does this component mate with other parts, and what are the shapes and dimensions of those mating components?
    • Do the mating components move during use?

    The answers to these questions dictate the overall size and shape of the component, along with the ideal materials and additives for the application.

    After determining the core design features, engineers can optimize for the limits and capabilities of extrusion. While extrusion can create a diverse range of profiles of almost any size, the most cost-effective products adhere to certain shapes and dimensions. When possible, designers should attempt to adhere to the following guidelines, which can speed manufacturing and improve part consistency:

    • Wall sections should be as balanced as possible, with an even wall thickness throughout the design.
    • When working with multiple small profiles, it may be beneficial to combine them into a single larger profile.
    • Interior detailing on hollow components should be kept to a minimum.
    • Radii should be as large as possible to prevent notching or cracking.
    • Thermoplastics expand and contract during processing, so tolerances should be as lenient as allowable for the application.

    The team at Applied Plastics can help evaluate your design for these and other criteria to ensure that extrusions proceed smoothly. Using CAD software, we create 2D and 3D models of the final components to give clients the best picture of how their design will turn out and to facilitate rapid modifications when necessary. Our experience-backed recommendations reduce lead times, cut costs, and improve part quality, making an already-efficient process even faster.


    After finalizing the design, your extrusion provider can begin to create tooling for your components. At Applied Plastics, we have over 60 years of experience in thermoplastic extrusion and manufacturing custom in-house tooling. We begin with the CAD drawings from the design process to determine the ideal tooling shape and identify any possible material interactions. We then use precision machining techniques to create custom tooling for the production process.

    As part of our manufacturing process, we use wire electrical discharge machining (EDM) to cut through metal using a hot wire and electrode. EDM machining allows for precise forming of conductive metal parts, including complex shapes with tight tolerances. EDM machining also prevents rust, which preserves tooling and decreases costs for high-volume production runs.


    The final step in the manufacturing process is the extrusion itself. We attach the custom die to an extruder machine, then load the chosen plastic materials into a hopper. The extruder melts the plastic, at which point a revolving screw pushes the molten material forward and through the die. This step forces the material to take on the desired shape. Finally, the plastic undergoes a controlled cooling process before any additional machining.

  2. 8 Thermoplastics That Are Ideal for Custom Extrusions

    Leave a Comment

    Applied Plastics provides custom plastic extrusions for almost every application, no matter how challenging. We produce tubing, profile shapes, and solid rods using a wide variety of materials. Thermoplastics have the advantage of being able to be reheated and remolded as required. Thermoset, on the other hand, is unable to be reheated or remolded after it’s formed. In this post, we will discuss a few of the most popular types of thermoplastics we offer.

    Which Thermoplastics are Best for Custom Extrusions


    Which Thermoplastics Are Best for Custom Extrusions?

    Thermoplastics are grouped commercially according to their material properties and typical applications. There are three groups they are organized into: commodity, engineering, and high performance. Commodity plastics are widely available, easy to process, and account for the majority of thermoplastic use. Engineering-grade plastics have properties that make them uniquely suited for certain applications, and high-performance plastics are specially engineered to have unique thermal and mechanical properties.

    The following materials span these three thermoplastic categories. They represent some of the most frequently chosen materials; however, Applied Plastics offers a much wider selection of extrusion materials than these types.

    1. Acrylonitrile Butadiene Styrene (ABS)

    ABS is a popular type of plastic due to its ease of machining and low production costs. It performs well in both high and low temperatures, displays impact resistance, and is easy to paint and glue. Extruded ABS offers excellent electrical insulation properties.

    2. Acrylic

    A strong, transparent polymer, acrylic is a stronger, more impact-resistant lightweight alternative to glass. It has a high level of clarity, resists electrical current and UV radiation, and is cost-effective.

    3. Polycarbonate

    Polycarbonate is extremely strong and shatterproof, which has led it to be used as a glass alternative in many applications. It is resistant to high temperatures and performs well in applications relating to protection, lighting, or glazing. Extruded polycarbonate is transparent but can be colored easily and has excellent light transmission abilities.

    4. Polyethylene

    Available in several forms, polyethylene is perhaps the most commonly used plastic material. It is highly versatile while being low-cost. Polyethylene extrusions are chemical-resistant, translucent, and strong. It can be easily produced in small diameters which is useful in many healthcare industry applications.

    5. Polyoxymethylene (POM) (Acetal / Delrin)

    Also known as Acetal or Delrin, polyoxymethylene is an engineering-grade thermoplastic designed to replace metal. It displays high tensile strength and is very resistant to heat and water absorption. It is used in applications requiring a strong, slippery, or flexible part.

    6. Polypropylene

    Polypropylene is a low-cost, recyclable material that is tolerant of high temperatures and chemical substances. It is highly durable and available in several grades, including food grade. Common applications include automotive components, toy parts, and gardening products.

    7. Polystyrene (XSP)

    Polystyrene is a hard plastic that is used to make many products. It can be combined with colorants or other plastics and has excellent insulating and cushioning properties. Polystyrene doesn’t react with metals, is low-cost, and is long-lasting. It is used in appliance manufacturing, the automotive and electronics industries, and more.

    8. Polyvinyl Chloride (PVC)

    PVC products are easily created through the extrusion process and can be manufactured to be rigid or flexible. Rigid PVC is the most commonly used form. It is lightweight but strong and used throughout industries such as automotive, construction, marine, and more. Flexible PVC is used in building applications, such as electrical wire insulation.

    Custom Extrusions From Applied Plastics

    Extruded plastics are created by heating the chosen material until it is melted. This process occurs within a long chamber called the extruder. As the material melts, a revolving screw pushes it forward and through a small opening. The plastic material takes on the shape of the opening, called the die, and forms the desired product. After it has cooled, it can be cut into the desired size.

    There are numerous plastic materials suitable for the extrusion process. Many of these materials are low-cost and have important characteristics such as strength and chemical resistance, which have led them to be widely adopted by many industries.
