Gain an edge with EnduroSharp® Scraper Blades

May 9, 2023  |  , ,

When using a tool for maintenance, it is important to use the right tool to perform the task the right way.  Using the incorrect tool wastes time, reduces efficiency, and puts the maintainer at risk of injury. Take for example a tool as basic as a scraper blade.  Not all scraper blades are made of the same material and provide the same functionality.  Some of the most common types of scraper blades on the market include Phenolic, Celcon®, Glass Filled Nylon, and Torlon®.

 

Phenolic Scraper Blades

Phenolic scraper blades come in assorted shapes, colors, and sizes.  Phenolic scrapers are commonly used for removing sealants, adhesives, stickers, labels, grime, and more.  Phenolic materials are the result of polymerization between layers of paper, canvas, linen, or glass cloth impregnated with a synthetic thermosetting resin.  It offers high resistance to flexing but does not offer the ability to be resharpened.  It will curl, peel and melt when attempting to resharpen.  Additionally, Phenolic may cause irritation to the skin, eyes, nose throat, and nervous system, so it is not ideal for use in incremental or heated material removal.

 

Celcon® Plastic Scraper Blades

Celcon® plastic scraper blades are currently approved by several MROs and are made of semi-crystalline thermoplastics that offer high tensile strength, stiffness, and toughness and may retain a sharp edge.  They are resistant to hot water and some solvents and are useful for sealant application, removal, and paint removal.  They are not, however, useful with newer aviation adhesives, or high-heat applications as they melt easily.  Celcon® dust may cause irritation in the upper respiratory tract when used at normal processing temperatures.

 

 

Glass-Filled NylonScraperBlades

Glass-filled nylon scraper blades are thermal polymers that hold a very sharp and hard edge.  It is far less likely to mar surfaces, but it is not categorized as non-marring.  Can sometimes often be reshaped, but edges tend to wear when prying.  Can not be re-sharpened. Resists chemicals and solvents with minimal degradation.  While adding glass to the nylon makes it substantially stronger, with superior tensile strength it is also substantially more brittle, abrasive, and heavier.

 

Torlon Scarper Blades

Torlon® scraper blades hold a superior edge, remove unwanted materials, and protect the underlying substrates.  Torlon® is a non-marring, high-strength, high-temperature polymer and is cured to produce a thermoset polymer.  As a thermoset, it is resharpenable, lightweight, chemically resistant, and safe for people under normal conditions.

EnduroSharp® offers a full line of Torlon® Aircraft Maintenance Tools that make the removal of sealants and adhesives more efficient.

Plastics Support Sustainability

May 4, 2023  |  , ,

Strong, lightweight plastics enable us to live better while contributing to sustainability in many ways—all which stem from plastics’ ability to help us do more with less.

Plastics help us protect the environment by reducing waste, lowering greenhouse gas emissions, and saving energy at home, at work, and on the road. Plastic packaging helps to dramatically extend the shelf life of products while allowing us to ship more with less packaging material—reducing both product and packaging waste.

Plastics have a great environmental profile.  Only 4% of the world’s oil production is used for plastics and it takes much less energy to produce compared to other materials.  Plastics are durable, lightweight, and adaptable, now being used in projects that used to require metal materials.

Plastic adhesives, sealants, tools, and other building products are making our lives significantly more energy efficient while reducing costs. Plastics are building blocks of many value chains including healthcare, aviation, packaging, and increasingly the recycling industry. Sustainable plastic manufacturing conducts business in a way that drives value for society, the environment, and industry.

High-Performance plastics offer superior product quality in terms of durability, reusability, and recyclable quantities.  They are used in a wide range of multi-use applications and durable applications and are frequently used to replace other materials such as metal, wood, and glass.

Peek use in Semi-Conductor Applications – Wafer Manufacturing

February 7, 2023  |  , , ,

 

PEEK is short for polyether ether ketone. These polymers are notable for their phenylene rings and oxygen bridges, which result in resilience, durability, and strength.

Wafer manufacturing is a term used to describe the process of creating chips, otherwise known as integrated circuits, which are used in everyday devices.  You will find chips in everything from cars to military jets.  PEEK is great for semiconductor applications because of its outstanding combination of physical properties.

  • Longer Lifetime – CMP (chemical-mechanical positioning) rings made with PEEK can provide less downtime, and more throughput with up 2x wear resistance compared to other materials.
  • Potential Yield Enhancement – Low particle generation and higher purity, resulting in lower outgassing and extractives that may lead to yield improvements
  • Faster Process – PEEK endures proceseess with up to 260° and harsh chemicals, which allos for faster processing and less cooling time.

Semiconductor equipment manufacturers use PEEK screws and fasteners in wet benches. Chip manufacturers use hydrofluoric acid which is a corrosive chemical that can damage metals. Since PEEK is chemical-resistant, chip manufacturers are utilizing PEEK screws. These screws are used in the production of ICU’s since they are a high-purity material and possess low-outgas properties. PEEK is also used to manufacture manifolds for semiconductor production equipment.

Performance Plastics’ team of experienced engineers possess the expertise to design and manufacture technically challenging projects and offer complex solutions within the semiconductor industry.

Does your part need Flexibility & Strength – Consider Nylon®

January 26, 2023  |  , , ,

Nylon® is a synthetic thermoplastic polyamide that is known for its strength, temperature resilience, and chemical compatibility. It has been proven to be a lightweight, heavy-duty industrial engineering plastic replacement for metals that are resistant to both heat and corrosive chemicals.

Nylon® is a great material for parts that undergo flexure and bending.  With wear resistance far greater than many metals and other thermoplastics and a low coefficient of friction, Nylon® is ideally suited for use in slides, bearings, and other parts that need to stand up to high levels of motion and wear. Performance Plastics offers expertise in developing Nylon® resin formulations and combinations with other polymers such as glass, carbon, and mineral-reinforced versions.  For example, Minlon®, a mineral-reinforced Nylon® provides greater dimensional stability and creep resistance than unreinforced Nylon®, and lower warpage than glass-reinforced Nylon®. As a result, it is popular for use in compressor valves and big industrial parts, as well as in demanding aerospace applications.

Performance Plastics has seen Nylon®’s applications grow to include a range of applications to move water, acids, lubricants, solvents, chemicals, and fuels in automotive, military, and aerospace environments.  Although pump makers traditionally used various metals for pump housings, shaft guides, impellers, seals, bushings, and other elements, the desire to reduce pump weight, material, and processing costs have led many to opt for various Nylon® formulations instead. Performance Plastics can use Nylon® to offer a combination of physical strength, wear resistance, self-lubrication, and high cost-effectiveness.

Choosing the optimal Nylon® resin for an application depends on several factors, including the levels of pressure, temperature, and speed involved. In addition, the abrasiveness of the liquids or slurries involved, the degree of contamination that can be tolerated, and projected uses for the part must also be considered.

Nylon®’s toughness and elongation properties make it suitable for designs that involve snap-fits or press-fits. Injection-molded Nylon® parts from Performance Plastics are well-suited to secondary machining processes such as turning, drilling, tapping, and grinding, as well as ultrasonic insertion, ultrasonic welding, pad printing, and assembly.

Vespel vs Torlon – Which material is best for my application?

January 12, 2023  |  , ,

When it comes to extremely high-temperature applications, engineered fluoropolymers are an optimal choice for reliability and performance. While there are several engineered resins available on the market, for the most demanding applications, project leaders often request Vespel® or Torlon®. Understanding the differences between these two resins, the production methods involved and the labor costs associated with the materials will help you determine which one is correct for your project.

Vespel® vs. Torlon®

Vespel® is a polyimide plastic that is often used in high-heat environments that cause thermoplastic materials to lose their mechanical properties. It is one of the most dynamic engineering resins available and can be found in hostile and extreme environments, such as oil & gas, semiconductors, and aerospace applications.

With the ability to perform at temperatures of 500ºF and to endure temperatures up to 900ºF for limited periods, Vespel® has superior thermal stability. This material is also known for excellent friction and wear characteristics, being extremely creep resistant, and having a high resistance to chemicals.

What You Don’t Know About FEP/PFA Injection Mold is Costing You Money

December 7, 2022  |  , , ,

A fluoropolymer is one of the growing numbers fluorocarbon-based polymers. They are widely used in healthcare applications due to their biocompatibility, lubricity, sterilizability, chemical inertness, thermal stability, barrier properties, and high purity. However, when compared with other resins, they are significantly more expensive and require special techniques to injection mold due to their shear sensitivity, high melt temperatures, and fluorine outgassing when melted.

Although the best-known fluoropolymer, polytetrafluoroethylene (PTFE or Teflon®), has been on the market since the 1940s, newer resins have been developed to address specific injection molding niches. Perfluoroalkoxy polymer (PFA) and fluorinated ethylene-propylene (FEP plastic) are among the most recent additions to the list of fluoropolymer options.

PFA was developed in order to create a true melt-processable fluoropolymer. It provides the smoothest and least wettable finish of all of the fluoropolymers. Its optical transparency, chemical inertness, and overall flexibility have made it popular for use in lab equipment. It also has superior electrical properties, with dielectric strength that’s three to four times greater than PTFE can offer.

Like PFA, FEP is melt-processable and injection moldable. Its melting point of 260 °C (500 °F) is about 40 degrees lower than PFA’s.  It offers low friction and chemical inertness properties comparable to PTFE’s. However, it is completely transparent. Because FEP is highly resistant to sunlight, it is especially useful for molding parts that are subjected to weathering.

However, not all injection molders are equipped to work with fluoropolymers like PFA and FEP. Performance Plastics LTD. has developed a variety of tools and procedures to address the challenges involved in molding these materials. For example, our solution includes a hot runner system and mold designed to minimize the shear forces inherent in the injection molding process. We use proprietary metallurgy that’s highly resistant to fluorine gas corrosion, which helps extend the working life of the hot runner system, tooling and other components that make contact with the melted resin. We’ve also developed a direct-gating, multi-runner approach to tool design that eliminates the sprue and runner used in traditional injection molding. By eliminating the wasted material associated with the sprue and runner, Performance Plastics has been able to pass along material cost savings of from 20% to 40% by using these expensive resins more economically.

To learn more about how we can cut your resin costs while helping you take advantage of the unique properties PFA and FEP offer, visit our contact page or contact Rich Reed, our vice president of sales and marketing, at (513) 321-8404 or [email protected].

Plastic Injection Molding vs 3D Printing (Part 2)

November 16, 2022  |  , , ,

How to choose the best technology for your project.

 

Plastic injection molding and 3D printing are both viable technologies. 3D printing is an additive printing process that creates objects by building up layers of material, while injection molding uses a mold that is filled with molten materials that cool and harden to produce parts.

The use of 3D printing in innovative and experimental scenarios is a viable technology for its ability to create custom plastic part designs quickly.  However, the 3D process limits your material choices, as all materials are not a fit or even available in a form suitable for 3D printing.

3D printing is best used for:

  • Quick turnaround times
  • Low volume, slower production speeds
  • Parts in the design phase with frequent changes – prototyping, lower product quality
  • Smaller part sizes

Once a design has been finalized, plastic injection molding becomes the optimal process.  Most of today’s plastic parts are manufactured using plastic injection molding – it’s best for producing large quantities quickly and reliably in high-volume runs. You have greater material options with plastic injection molding, and you can control material weight, cost, and flexibility with endless combinations of materials.  It helps organizations control the cost and integrity of designs with complexities and tight tolerances.

Plastic Injection molding is best used for:

  • High volume
  • Finalized part design
  • Enhanced strength and durability
  • Complex, precision, detailed parts

At Performance Plastics we have optimized many projects that were once manufactured using 3D printing, only to discover that injection molding was the more efficient technology.  As experts in FEP, PFA, PAI (Torlon), PEEK, and Ultem resins we frequently work with mission-critical, time-sensitive applications.  3D printing is an essential component of the design process, but If you have a project that requires high volume (5,000+ parts per year), high-temperature resins, and tight tolerances with complex geometries, plastic injection molding is your solution.

Performance Plastics’ team of experienced engineers possesses the expertise to design and manufacture technically challenging projects and offer complex solutions within harsh application industries.
