PEEK® for Aerospace/Defense Applications

September 26, 2022  |  , ,

PEEK or polyetheretherketone belongs to a family of polymers called polyketones or iPAEKs.  This means that is it built from the following building blocks:

  • ARYL
  • ETHER
  • KETONE

PEEK is one of the highest performing thermoplastics in the world.  Compared to metals, PEEK based materials are very light weight, easily shaped, resistant to corrosion and have considerably higher specific strength (strength per unit weight).

PEEK is optimal for aerospace applications because although it is a thermoplastic, it boasts heat resistance, little to no reaction against harmful chemicals and radiation, and comparable tensile and load strength to that of titanium and steel while being many times lighter.

PEEK® does not offer merely two or three properties that mark it as the polymer of choice for aerospace/defense; it has a whole variety of them.  They include:

  • High heat resistance

Tests have shown that PEEK polymer has a continuous use temperature of 260°C (500°F). This can make it suitable for use in a wide range of thermally aggressive environments.  PEEK tolerates friction and resists wear in dynamic applications like thrust washers and seal rings.

  • Chemically unreactive

PEEK resists the damage that can be inflicted in chemically aggressive operational environments. It can resist jet fuel, hydraulic fluids, de-icers and insecticides used in the aerospace industry.  This holds true over wide ranges of pressure, temperature, and time.

  • Mechanically strong

PEEK offers excellent strength and stiffness over a wide temperature range.  PEEK-based composites have specific strength many times that of metals and alloys.  “Creep” refers to a material becoming permanently deformed over an extended period when under constant applied stress. “Fatigue” refers to the brittle failure of a material under a repeated cyclic loading.  PEEK has both high creep and fatigue resistance thanks to its semi-crystalline structure and has been shown to be more durable than many other polymers and some metals over a long and useful lifetime.

  • Difficult to ignite or burn

PEEK has excellent flammability performance.  It resists combustion up to almost 600°C.  When it can be made to burn at very high temperatures, it will not support combustion and it emits little smoke. This is one reason why PEEK is widely used in commercial aircraft.

Aerospace/defense part manufacturers now use PEEK as a way to improve the weight and durability of their parts.  PEEK is a standard high-performance plastics in the aerospace/defense industry applications.

Performance Plastics’ team of experienced engineers possess the expertise to design and manufacture technically challenging projects and offer complex solutions within the aerospace/defense industries.

The real cost of making an injection mold

August 9, 2022  |  , , , ,

When starting to produce a new product, it’s important to decide on the type of process you will use for the manufacturing process.  While injection molding is a very cost-effective process, the initial startup cost of the mold is often a barrier of entry.

Injection molding is a manufacturing process that is very efficient for producing parts in large volume.  It is typically used in the mass production process where the same part is being created in the thousands or even millions.

Upfront costs tend to be very high due to the design, testing, and tooling requirements.  If you are going to produce parts in high volumes, you want to make sure you get the design correct the first time. So, what are the costs associated with producing an injection mold?

  • Choice of Resin

One of the biggest factors that effect the price of the plastic injection molding process is the type of plastic resin used in manufacturing.  The choice of material will change the price based on color, compounding, and additives.  The most abrasive or corrosive the material, the most expensive the mold.

  • Complexity

The more intricate the component, the more difficult it is to design the manufacturing process.  Part complexity, tolerances, number of undercuts as well as surface finish all effect the cost.

  • Size

The size of the component also drives the price.  Larger parts require larger, more expensive molds, as well as more material to manufacture.  Larger molds also take longer to make, which increases the costs.

  • Mold Material

The material the mold is made from significantly impacts the price.  Short production molds are usually made from less expensive materials such as aluminum.  Long production molds require molds made from more durable and expensive materials like steel that will retain their features across several years.

  • Cavities

The higher the number of cavities – the higher the production costs.  Experienced mold designers can maximize cavitations to enhance productivity and lower costs even for the most intricate parts and components.

  • Mold Base

The base of the mold is the case used for holding all the components, inserts and cavities of the mold.  The price of the mold base depends on the type of steel and the size of the mold.

At Performance Plastics, we know how important it is to make the correct decisions when designing a mold.  We have a team of process experts who work with our clients to design and assist in the mold process. We focus on the total cost of ownership of a mold, production capacity, longevity, functionality, as well as initial capital expense.

EnduroSharp® Torlon® Aircraft Maintenance Tools – Why Use a Pneumatic Tool

July 27, 2022  |  , , ,

EnduroSharp® has improved the way aerospace maintenance professionals remove sealants and adhesives from substrates and fasteners.  EnduroSharp® resharpenable, non-marring tools are made from Torlon®, a high strength polymer, creating a non-metallic blade tool that will not damage composite structures during use.

Many of our EnduroSharp® tools can be used in conjunction with a pneumatic tool.  A pneumatic tool is one that’s driven with the assistance of compressed air rather than electricity.  Pneumatic tools rely on air compressors to provide a burst of air to perform its operation. A pneumatic tool can operate indefinitely as long as the attached air compressor can deliver the required volume and pressure without interruption.

Pneumatic Tools are very strong air powered tools and provide the user with a tremendous amount of labor and time saving torque.

Pneumatic tools provide many advantages:

  • Main advantage is they are far less expensive than their electric alternatives.
  • Provide a degree of safety in wet areas where electric motors can be dangerous.
  • Lighter in weight than their electric counterparts.
  • Pneumatic tools can deliver large amounts of torque or operate for long durations of time.
  • More flexible than electric – nearly all air-driven tools use the same ¼” quick connect fittings.

Generally, pneumatic tools are smaller, more versatile, easy-to-use and safer than traditional electric tools.  Since pneumatic tools are usually lighter, the user is able to have better control and experience less fatigue and strain.  They are also able to withstand various elements such as dust, heat and water better than electric tools.

The EnduroSharp® Pneumatic Tool for Scraper Blades is just one of the many products offered in the EnduroSharp® Product line. Contact Rich Reed,  Vice President of Sales and Marketing, at (513) 321-8404 or [email protected], for more information.

Benefits of Reshoring for Medical Device Manufacturers

June 28, 2022  |  , , , ,

Medical devices must be dependable and safe, and moving operations back to the United States allow companies to have better control over the entire operation – procurement, engineering, production, and distribution.  The result is a higher standard of quality in products.  Medical device companies and other advanced industries need to have extensive and precise control over the entire supply chain of their products.

As an American small business, Performance Plastics is pleased to see the trend of manufacturing operations moving back to the United States.  A range of economic and strategic factors due to the recent epidemic have tipped the scales exponentially since 2020.

While there are many benefits of reshoring, some of the most important reasons include:

  • Greater Control of Supply Chain

Getting all your moving pieces to work seamlessly can be a near impossible task, especially across language and time zone barriers.  One of the primary advantages of reshoring is that it allows you to tighten your supply chain.

  • Reduced Lead Times

The greater the distance between where your device is manufactured and where you are located, the longer you can expect your lead time to be.  However, distance is not the only factor.  When moving from one country to another, inspection and transportation times between countries can add up to 50% to your lead time.

  • Fewer Import Tariffs

Import tariffs vary from administration to administration, but they will always be in place.  The recent increase in tariffs have caused the cost advantages of manufacturing offshore to shrink.

  • Reduced Energy Costs

Recent changes to international gas and power prices have drastically increased the prices of manufacturing and transportation from other countries.  Impact on the environment and achieving higher sustainability are very important to consumers.

  • Potential to Improve Brand Perception

Although we live in an international community, the origin of a product still has an impact on the perception of quality.  Some lower cost manufacturing countries even have a perception of being “dangerous”.

Medical devices necessitate the highest quality standards possible, which can’t always be regulated in an offshore manufacturing environment.  The vast global, economic, legal and social changes are all very dynamic and unpredictable in nature – making relocating operations a more sustainable, stable and efficient choice.

At Performance Plastics, we are experts in injection molding, specializing in high performance plastics for medical device components. Our proprietary tool design software, processes and equipment enable us to injection mold components having complex geometries made from challenging ultra, high-performance thermoplastic materials, and reinforced compounds.

EnduroSharp® Torlon® Scraper Blades and Gap Blades – What’s the Difference?

June 23, 2022  |  , , ,

 

EnduroSharp(R) Gap Blades & Adapter

EnduroSharp® has changed the way aerospace maintenance professionals remove sealants and adhesives from substrates and fasteners. EnduroSharp® resharpenable tools are made from Torlon®, a high strength polymer, creating a non-metallic blade tool that will not damage composite structures during use.

Scraper blades are designed for use in larger areas where a large quantity of material needs to be removed. Made from a non-marring Torlon® material the blades are a quick, safe and effective method of removing sealants and adhesives from composite structures.

Gap blades are designed for use in smaller grooves and channels where scraper blades are too large.  With a multi head edge, gap blades offer the ability to eliminate materials from multiple surfaces of the seam.

Technicians often use a scraper blade in applications where a gap blade will deliver a quicker, cleaner result.  While the scraper blade offers one cutting edge, the gap blades offer three, allowing the removal of sealants and adhesives from the surfaces more completely.                                                   

The tools are designed to complement each other.  By using an adapter tool, both the scraper blades and gap blades can be used with the same handle.  This provides the technician the ability to switch the blades based on the progression in the removal process.

Using the adapter also allows for the application of flexible incremental skiving techniques when removing sealants and adhesives.  Incremental skiving involves the technique of removing subsequent thin layers of material to achieve a cleaner finish.  The technician can switch back and forth between the blades as needed.

The EnduroSharp® scraper and gap blades are just a few of the many products offered in the EnduroSharp® Product line.
