Plastic injection molding and plastic extrusion are both popular manufacturing processes used to create plastic parts, but they differ significantly in their methods and applications. While they both produce high quality flurorpolymer parts, plastic injection molding produces three-dimensional shapes vs. plastic extrusion produces linear, two-dimensional shapes.





  • Injection Molding:  This process involves injecting molten plastic material into a mold cavity, where it cools and solidifies to form the desired shape. The mold typically consists of two halves and the material is injected under high pressure.
  • Extrusion:  In extrusion, plastic material is melted and forced through a die tocreate a continuous profile. The die gives the plastic its desired shape,and the material is cooled and solidified as it exits the die.


  •  Injection Molding:  Injection molding machines consist of a hopper where the plastic pelletsare fed into a heated barrel. Inside the barrel, the pellets melt and are injected into the mold cavity.
  •  Extrusion:  Extrusion machinery includes an extruder, which is essentially a long barrel with a screw conveyor inside. The plastic pellets are fed into one end of the extruder, where they are heated, melted, and forced through a die at the other end.


  • Injection Molding:  This process is commonly used for producing intricate and complex parts with high precision and repeatability. It’s used in industries such as aerospace/defense, industrial, electronics, and medical devices.
  • Extrusion:  Extrusion is often used to create continuous lengths of plastic profiles or sheets with a consistent cross-section. It’s employed in applications such as pipes, tubing, window frames, and traffic control items.

Complexity and Cost:

  •  Injection Molding:  Tooling costs for injection molding can be higher due to the need for precision molds, especially for complex parts. However, once the mold is made, the cost per part can be relatively low.
  • Extrusion:  Extrusion tooling costs are generally lower compared to injection molding, especially for simple profiles. However, the process may not be as suitable for highly complex shapes.

Material Variation:

  • Injection Molding:  A wide range of thermoplastics such as FEP, PFA, Torlon, etc., can be used in injection molding, allowing for flexibility in material selection.
  • Extrusion:  While extrusion also supports various fluoropolymer materials, the process is particularly suited for thermoplastics that can be melted and reshaped repeatedly.

In summary, while both plastic injection molding and plastic extrusion are versatile manufacturing processes used in the plastics industry, they each have applications suited to different types of products and applications.

Plastic injection molding is best applied to three-dimensional shapes, while plastic extrusion is best suited for two-dimensional shapes.

Aircraft Maintenance Professionals are always looking for better and more efficient ways to complete their tasks.  Sometimes, in an effort to complete their tasks faster, they use items that were not designed for use in removal and damage to the underlying surfaces.

While there are currently many scraper blades on the market that are designed for adhesive removal, , not all materials are created equal.  Most of the blades currently on the market are made of three materials:  ABS, Phenolic, and Torlon.



Acrylonitrile Butadiene Styrene is a very tough, very durable thermoplastic used in a wide variety of applications. ABS is a common choice among other plastic production materials because of its durability, structural stability, and good corrosion, impact, chemical, and wear resistance.

ABS plastic is made when acrylonitrile and polystyrene monomers are polymerized with butadiene rubber to create acrylonitrile butadiene styrene (ABS). This blending is typically accomplished using an emulsification process, wherein materials that would otherwise not mix are formulated into a cohesive single product (think milk, where fats, oil, and water do not separate out of solution but exist as a homogenous mixture)


Phenolic is a laminated plastic used in a variety of custom plastic components due to its high strength, resistance to solvents, dielectric strength, and many other features.

Phenolics are manufactured by impregnating layers of material with a phenolic resin, and then applying heat and pressure, which transforms these layers into a solid mass. The result is a thermoset that is dense, dimensionally stable, structurally strong, has low creep, and is an excellent insulator.




Torlon® is a high-strength, high-performance, melt-processable plastic material. It’s ability to perform under severe stress combined with its resistance to elevated temperatures makes it ideal for various applications across many industries.  Torlon (PAI) is recognized as being the highest-performing plastic that is melt-processable.

Polyamide-imides (PAIs) are thermoplastic amorphous polymers prepared by the condensation of an aromatic diamine, such as methylene diamine, and an anhydride, such as trimellitic acid chloride. PAIs have good mechanical, thermal, and chemical resistance, high strength, melt processability, and high heat capacity.

So, ABS is blended thermoplastic, Phenolic is impregnated plastic, and Torlon is a heat-treated, condensed thermoset.  Condensed thermoset materials are stronger, more resilient, and exhibit consistent performance without the risk of damaging the surfaces.

EnduroSharp® Torlon® aircraft maintenance tools were specifically designed by Performance Plastics, the Airforce Research Laboratory (ARL), and the University of Dayton Research Institute at Wright Patterson Air Force Base to safely and efficiently remove adhesives, sealants, and coatings while maintaining an effective edge and not damaging the underlying substrates.
