Connection Technology Pin & Socket Contact Technologies   Five proven connection technologies. One commitment to performance. 1. Crimped Crimped contacts are used to terminate multistrand wires, ensuring reliable and secure connections. The process involves pressing the wires into the contact, which can take the form of a pin or socket depending on the application. To learn more about our crimped contact pins – click here. 2. Press-fit A popular method, which may include additional pin features based on tolerances, achieves a snug fit by leveraging material properties. For instance, a press-fit is suitable for plastic assemblies when a client needs a connector. To learn more about our connector solutions – click here. 3. Staked Staking is a mechanical technique used to hit the pin from one end. It is commonly used for metal, ceramic, and plastic materials. This versatile approach comes in various forms: petal (for lamp bases), flatted (rivet-like), or control (for double-sided male pins). These options cater to different industry needs, ensuring optimal functionality and precision. The Slimline Bulb Pin is a great example of our Staked Pins. If you’d like to see an example of the slimline pin – click here. 4. Soldered A less common approach for hollow pins, but can be used for larger diameter pins when the application is taking advantage of the low overall weight of a hollow pin. 5. Overmolded Another infrequent approach for hollow pins occurs when the pin is encompassed within a molding material, ensuring stability and security.

    Our custom hollow pins provide the functionality you need with 30–70% material savings compared with machined pins.     Connection Technology Connection Technologies for Custom Hollow Pins Crimped, press-fit, staked and overmolded methods are selected around assembly structure, material behavior, retention requirements and production needs. Hero Technology Wire Termination Technology Crimped Crimped contacts terminate multistrand wires through controlled mechanical compression, creating reliable electrical continuity and secure retention. Use CaseReliable wire termination. Key StrengthSecure, consistent retention. Engineering FocusCompression, fit, repeatability. Interference Fit Press-fit Uses tolerance control and material elasticity to create a secure, solder-free interference fit for structured assemblies. Best for: controlled insertion and stable retention. Mechanical Locking Staked Mechanically deforms the pin end to lock it into metal, ceramic or plastic assemblies. Best for: strong positional locking. Integrated Assembly Overmolded Encapsulates the contact within molding material to improve stability and security in integrated assemblies. Best for: integrated structural and electrical assemblies.
