Connectors may be small, but their functionality in many aerospace applications is hugely important. These small but mighty parts present a number of machining challenges, so it’s important to find the right partner for the job.

At Heinz Engineering, we’re the connector experts! Our team is well equipped to make top-notch connectors thanks to our sophisticated aerospace machining capabilities and our unwavering commitment to quality.

What Are Connectors? 

In simplest terms, connectors fasten one part to another. They are an excellent alternative to fusing parts together permanently, as they provide the ability to assemble and reassemble parts with ease. 

Connectors can be made out of standard aerospace materials like aluminum, stainless steel, nickel, titanium, and Inconel. They serve many purposes and are even capable of holding fluid or wires when properly configured. 

Although we make connectors primarily for aerospace customers, these versatile parts are commonly found in the medical and automotive industries as well. 

Challenges of Machining Aerospace Connectors

Connectors range from simple to complex depending on the application. But what makes connectors so important is that they’re very often mission critical parts.

Here’s what makes some connectors so challenging to machine and why we’re best suited to make these parts:

Aerospace Connectors

  • Broaching. Many connectors require a process called broaching to machine square cuts in the material. These features ensure a strong, tight fit for the connector. Our trusted vendors specialize in broaching the tightest tolerances for essential aerospace parts.
  • G-forces. Parts built for aviation must be able to withstand the extremely high g-forces produced by flight. Because we specialize in aerospace machining, we know what it takes to account for the most substantial g-force ratios.
  • Tight tolerances. Connectors require holding tight tolerances to ensure that mated parts fit together perfectly. With our advanced CNC machining capabilities, we guarantee a secure fit every time.
  • Finishing and processing. The optimal finishing process is highly dependent on the application. Common finishing processes for connectors include: 
    • Anodize: an electrochemical process that enhances the surface of nonferrous metals to provide a durable, corrosion-resistant finish. (Anodizing increases the thickness of a part, which we account for during machining to ensure that the final part maintains all critical tolerances.) 
    • Chemical film: a chemical coating that’s used to protect substrates from corrosion while leaving dimensions unchanged.
    • Electropolish: an electro-mechanical process that removes material to smooth surface roughness and improve finish.
  • Quality inspection. Our stringent quality inspection process includes fluorescent penetrant inspection and magnetic particle inspection. We make sure there are no fractures that could compromise the integrity of our connectors before sending them out to customers.
