Anodizing increases corrosion resistance and enhances your product’s aesthetic appearance. Watch our video to see the anodizing process in action!

Anodizing Materials

Aluminum is the most ideal material for anodizing. ‍

The Anodizing Process

Anodizing is an electrolytic passivation process that grows the natural oxide layer on cnc machining aluminum parts to protect them from wear and corrosion and make them look attractive. Known as a conversion coating (like Chem film or Alodine™), the anodizing process causes the surface of the aluminum to recede dimensionally, before the protective oxide layer is built up. When the anodizing process is complete, the oxide layer is chemically bonded to the aluminum substrate below, meaning it won’t chip or flake.

Anodizing is an electrolytic passivation process that grows the natural oxide layer on CNC machined aluminum parts to protect them from wear and corrosion and make them look attractive. This post-processing step in CNC machining is crucial, as it enhances both the functional and aesthetic qualities of the parts. Known as a conversion coating (like Chem film or Alodine™), the anodizing process causes the surface of the aluminum to recede dimensionally, before the protective oxide layer is built up.

Rinse Cycle

The first step in the anodizing process is the rinse cycle, during which a cleaning solution removes debris to ensure uniform coating.

‍Sulfuric Acid Bath

Next, electricity is used to drive the reaction and develop the coating. The name anodizing comes from the fact that the treated part forms an anode (positive electrode) in an electrical circuit. During this process, the part to be anodized is hung on a conductive rack, submerged in an electrolytic solution, and a direct current of electricity is introduced. While the acidity of the solution dissolves the oxide layer of the part, the electric current releases oxygen at its surface, which builds up a protective layer of aluminum oxide. By balancing dissolve rate with build-up rate, the oxide layer forms with nanopores, which allows continued growth of the coating beyond what is naturally possible.

Dye Bath

After primary coating and before sealing, dye can be applied in a variety of colors. The most popular colors are clear and black, followed by grey, red, blue, and gold. Fictiv offers approximate color matching at additional cost. Contact us for more information.

Sealant Bath

The final step of the anodizing process involves sealing the nanopores, so they can’t become passageways for corrosion initiation. Just before sealing, the nanopores are often filled with other corrosion inhibitors (or colored dyes, as mentioned above). After the process is complete, the coating will be 0.0002-0.0012” in thickness, in accordance with the common engineering spec MIL-A-8625 Type II.

Give Bella Hadid a theatrical prop to work with on set and she'll produce an entire performance in the short span of an ad campaign cameo. That prop might come in the form of lengthy tresses such as the hair extensions Hadid debuted on social media in October or the Swarovski crystals that cover every inch of her body and hair in the behind-the-scenes photos she shared on Instagram November 27.  

The model was appointed as Swarovski's holiday muse in its most recent campaign and if you take a look at the jewelry brand's official Instagram page, you'll see photos of Hadid's neck and wrists adorned in a silhouette of gleaming jewels. And the jewels have been individually placed along her slicked-back Tinkerbell bun and actually cover the entire perimeter of her sheer, nude bodysuit. 

She gives ballerina energy as her arms are extended above her head in the first photo. The jewels on both of her wrists appear to be weightless as she sways her arms in a swan-like pose. And in the third of four photos, a village of creatives works on Hadid's final look for the campaign photo shoot with one setting the crystals into place holding a blowdryer with a diffuser attachment near her bun, while another works on Hadid's nails for a Swarovski-infused manicure. 

Instagram content

This content can also be viewed on the site it originates from.

Her hairstyle in particular has got me dreaming up a do-it-yourself project for the Christmas and New Year's holidays to come. I'll be adding the TikTok-viral gem stamper to my Amazon cart stat and re-creating Hadid's truly whimsical bun.

Aerospace injection molding produces plastic prototypes and production-quality parts for aerospace applications. These custom components include brackets and mounts, ducts and vents, covers and panels, and guides and sleeves. From aircraft interiors to airframes; from cabins to engines; and from turbine blades to landing gear, aerospace plastic injection molding can turn your designs into reality – if you know where to look.

Injection molded aerospace parts can be found around aircraft, satellites, and spacecraft.

How to Find an Aerospace Injection Molder

Fictiv works with a carefully vetted network of injection molding partners who can meet the specific needs of aerospace customers. Importantly, we also provide design for manufacturing (DFM) assistance so you can optimize part designs for cost and performance. For faster cycle times, tighter tolerances, and AS9100 quality, companies like Honeywell Aerospace choose Fictiv. 

“Fictiv does an incredible job connecting my needs as a customer to those suppliers that have the capability, the right competitive cost, and the capacity to build my product and get it to me in a very rapid cycle time.” – Jon Hobgood, Vice President at Honeywell

Keep reading to learn more and request a quote for plastic aerospace prototypes and injection molded parts.

Why Aerospace Injection Molding is Different

All types of injection molding processes have commonalities. Whether for prototyping or production, the process begins when molten material is injected into the cavity of a mold. The part material, typically a thermoplastic, then solidifies into the shape of the mold before it’s ejected. Sometimes, secondary processes such as machining, painting, welding, assembly, and packaging are needed.

It’s important to remember that not all injection molders can produce plastic parts with the quality that aerospace customers need. When it comes to aerospace injection molding services, there are four things to look for in a potential partner.

1. High precision
2. Advanced materials
3. AS9100 quality
4. AS9102 first article inspections 

The following sections explain.

High Precision Aerospace Parts

Injection molded aerospace parts require a high degree of precision to ensure safety and performance. Accuracy refers to how close a measurement is to an accepted value, but precision refers to how close measurements of the same part are to each other. Even minor variations can represent manufacturing defects requiring designers to specify tight injection molding tolerances. In turn, injection molders need to use precision tooling and maintain tight controls over quality systems to ensure conformance.

Aerospace Tolerances

Most injection molds are machined to tolerances of ±0.127 mm, but aerospace parts may need tools machined to ±0.0508 mm or even ±0.0254 mm. However, parts with tight tolerances require steel molds, and steel injection molds cost more than aluminum. Usually, steel also takes longer to machine, so there’s a risk that projects with tight timetables could face delays. If a design change becomes necessary, there are additional costs and longer tool making time to consider.

Aerospace Injection Molds

When you partner with Fictiv, you’ll receive DFM assistance that can help you avoid these and other risks. Plus, you can get T1 samples in just two weeks – even using aerospace plastic injection molds that are made of steel. For prototype injection molding, tools made of soft and semi-hardened steels take less time to machine and provide the fine tolerances you need. For production runs, hardened steel molds can produce high-precision aerospace parts in higher volumes across many cycles.

Aerospace molds are made of soft steel, hardened steel, and semi-hardened steel.

Advanced Materials for Aerospace Injection Molding

Aerospace plastic injection molding services use advanced materials that meet strict standards for strength, durability, and resistance to extreme conditions such as high temperatures, pressures, and chemical exposure. Typically, high-performance thermoplastics, composites, and engineered resins are used. Sometimes, an aerospace designer can use less expensive materials during prototyping and more expensive options during production.

The table below describes advanced materials for aerospace injection molding.

Some aerospace plastics are also used in other applications. For example, glass-filled nylon provides strength and stiffness in aircraft parts, but it’s also used in automobile engine covers. PEEK comes in aerospace grades, but there are also grades for medical applications. Fictiv can help you choose the right resin for your project and works with manufacturing partners who can handle hard-to-process materials.

AS9100 certification demonstrates an injection molder’s commitment to quality. 

AS9100 Certified Injection Molding

AS9100 certification is a well-known quality management standard for the aerospace industry. It’s also used by defense industries. Not all injection molders are AS9100 certified, so it’s important to determine whether a potential partner can meet your standards for quality. AS9100 certification isn’t required for all aerospace parts production, but Fictiv’s global network of manufacturer partners includes AS9100 certified injection molders with deep industry experience.

AS9100 Quality

There are many advantages to choosing AS9100 certified injection molding: 

• Quality Management System (QMS): Injection molders who establish, implement, and maintain an AS9100 QMS perform regular quality audits and are committed to continuous improvement.
• Documentation and Traceability: AS9100 certification requires an aerospace injection molding service to collect and maintain detailed records of its processes. This includes material certifications, production controls, and inspection results.
• Process Control: Molders that maintain strict process control can ensure consistency, precision, and adherence to design specifications. During the aerospace injection molding process, this includes monitoring equipment parameters such as temperature, pressure, and cycle times.
• Risk Management: Aerospace injection molders with risk management processes are better able to identify, assess, and mitigate the risks associated with producing aerospace components. Examples include problems with tolerance stack-ups in assemblies.  
• Supplier Management: AS9100 certified injection molders ensure their suppliers and subcontractors (such as toolmakers) also meet stringent quality requirements. In addition to performing regular evaluations, these molders audit supplier performance.

AS9102 First Article Inspection

AS9102 First Article Inspection (FAI) is part of the AS9100 standard and verifies that a manufacturing process, tool, and material can produce aerospace parts that meet all engineering specifications and requirements. Specifically, AS9102 ensures that the first piece is produced correctly and that a manufacturer can consistently produce conforming parts. In other words, it’s essential for high-precision parts with limited part-to-part variability.

AS9102 Forms for Aerospace Injection Molding

AS9102 encompasses documentation requirements for capturing data during the FAI process. This data includes dimensional measurements, material certifications, process validations, and functional tests. There are also three numbered forms for aerospace injection molders to complete.

• Form 1: Part Number Accountability – Contains information about the part being inspected, such as part number and revision level.
• Form 2: Product Accountability – Documents the materials, special processes, and functional tests that are required for the part.
• Form 3: Characteristic Accountability – Captures detailed measurements and inspection results for part characteristics such as dimensions, tolerances, and notes from the engineering drawing.

FAI Inspections

FAI inspection involves a detailed examination and measurement of the first production part. Along with verifying that all design features and engineering specifications are met, an aerospace injection molder must verify each measurement and inspection result. Before full parts production begins, it’s essential to address and resolve any deviations. Sometimes, non-destructive testing (NDT) is used.

Traceability

In aviation, traceability is increasingly important because of how some recently manufactured jets contained components made from titanium that were sold using fake documentation. The FAI process is designed to ensure complete traceability of materials, processes, and inspection results for aerospace components. In turn, this helps identify the root causes of any problems so that suppliers can implement corrective actions.

Approvals, Revisions, and Changes

After the AS9102 FAI is complete, the data is reviewed. An approval signifies that the injection molded part meets all requirements and that the production process has been validated. Although FAIs are associated with new parts, they’re also used when there are significant changes to part design, materials, tooling, or manufacturing process.

A novel method for treating oily wastewater uses superhydrophilic TiSe2 nanospheres and an electric field for in-situ aeration and dielectrophoresis. This strategy improves fouling resistance by 90% and achieves separation efficiencies of over 99% for oil-in-water emulsions. Utilizing the high salinity of seawater, the method remains effective even after four months of use.

Membrane fouling is a significant barrier to the development of membrane separation processes, particularly in the treatment of oily wastewater resulting from frequent offshore oil spills. A green and sustainable solution is imperative to address this environmental concern. This paper presents a novel method involving the in-situ growth of superhydrophilic TiSe2 nanospheres on foam titanium via a one-step hydrothermal method. Supported by an external electric field, a dual anti-fouling strategy involving in-situ aeration and dielectrophoresis was developed, resulting in a remarkably improved fouling resistance by 90 %.

Unlike prior methods focusing predominantly on developing super-wettability surfaces for passive anti-fouling, the strategy in this work leveraged the high salinity inherent in seawater to introduce in-situ aeration and dielectrophoresis forces to the filtration process. This innovative approach actively prevented oil droplets from contacting the filtration material surface, achieving effective active anti-fouling. The synthesized TiSe2/TF(TTF) demonstrated separation efficiencies of over 99 % for four different oil-in-water emulsions.
