Wire types & sizes

You must identify the wire types and sizes used in your production. The terminal crimping machine needs to handle these specifications to ensure reliable connections. Copper wires offer high conductivity and resilience. Aluminum wires provide a lightweight option for certain applications. The American Wire Gauge (AWG) system helps you select the right diameter for your harness. Larger AWG numbers mean smaller wire diameters. Review the table below to understand common wire types and sizing:

AWG Sizes

Standard sizing system, larger numbers indicate smaller diameters

Volume needs

You must assess your production volume before selecting a terminal crimping machine. High-volume operations require machines that deliver speed and consistency. Automated designs minimize manual labor and speed up production. Consistent lengths and pre-terminated connectors make handling easier for machines. When you match machine compatibility to your volume needs, you streamline processes and reduce errors. This approach improves consistency and lowers the risk of interruptions in your production line.

  • Machine compatibility streamlines processes, which enhances overall manufacturing efficiency.

  • It reduces errors and improves consistency in production.

  • Automated designs minimize manual labor and speed up production.

  • Consistent lengths and pre-terminated connectors facilitate easier handling by machines.

  • This compatibility leads to fewer interruptions in production lines, lowering the risk of human error.

Terminal types

You must select a terminal crimping machine that supports the terminal types used in your harnesses. Different terminals suit different applications. Ring terminals provide maximum security for switchgear and heavy machinery. Spade terminals allow quick connection and disconnection in control panels and automotive systems. Pin terminals fit into terminal blocks and connectors for relay connections and PCB boards. Blade terminals offer efficient current transfer in automotive, appliances, and HVAC systems. Review the table below to match terminal types to your needs:

Crimping force & precision

You need to select a terminal crimping machine that delivers the right crimping force for your wire gauge. Proper force ensures strong mechanical and electrical connections. If the force is too low, terminals can pull out or fail under vibration. If the force is too high, wires may break or insulation may be damaged. Crimping precision affects the electrical performance and durability of your wire harness. The crimp height determines compression, contact, and strength. An optimal crimp height gives you stable conductivity and reliable pull force. Improper crimping can cause voltage drops or sudden circuit failures.

Note: According to IPC/WHMA-A-620, a 20 AWG crimp must withstand at least 55 N pull force. For critical applications, you should add a safety margin.

Hechang terminal crimping machines deliver high precision and consistent force. You can rely on them for stable electrical connections and long-term durability.

Automation options

You can boost your productivity with automation. Automated terminal crimping machines reduce cycle times to about two seconds per crimp. High-volume systems reach up to 1,800 crimps per hour. Manual processes only yield 50 to 100 crimps per hour. Automation lets you focus on quality oversight and material preparation. Automatic machines ensure consistent crimp parameters and eliminate variability.

  • Automation increases production speed and consistency.

  • Proper parameter settings improve both efficiency and product quality.

Hechang offers advanced automation options. You can choose machines that match your production volume and workflow.

Tooling compatibility

You must check tooling compatibility with your wire gauge, insulation, and terminal types. Reliable electrical connections depend on matched tooling. The right selection affects mechanical stability, electrical integrity, and environmental resilience.

  • Tooling must fit your wire gauge and insulation.

  • Proper insulation prevents shorting and protects terminals from contaminants.

  • Compliance certifications for dielectric strength and flame-retardant properties are necessary for safety.

  • Crimp terminals provide a gas-tight seal, enhancing performance and preventing corrosion.

  • Calibrated crimping tools and matched die sets ensure repeatability and reliability.

Hechang terminal crimping machines support a wide range of tooling. You can use them for various wire types and terminals, meeting industry standards.

Changeover speed

You need fast changeover speed to handle different wire harnesses and terminal types. Quick changeovers reduce downtime and keep your production line moving. Machines with easy-to-swap tooling and intuitive controls help you adapt to new jobs quickly. Hechang designs terminal crimping machines for efficient changeover. You can switch between wire sizes and terminal types with minimal effort.

Tip: Fast changeover speed increases flexibility and productivity in your wire harness production.

Safety features

You must prioritize safety when choosing a terminal crimping machine. Essential safety features protect operators and prevent workplace accidents.

  • Always wear eye protection and heavy-duty gloves.

  • Use only manufacturer-approved dies and fittings.

  • Never crimp a damaged, rusted, or reused ferrule.

  • Do not exceed recommended crimp diameter.

  • Inspect hoses for wear, cracks, and bulges before crimping.

  • Keep hands away from the die area during operation.

  • Test crimps under controlled pressure before returning to service.

Hechang terminal crimping machines include robust safety features. You can operate them with confidence and reduce risks in your facility.

Callout: Reliable crimping methods and quality checks, such as pull-force testing and go/no-go gaging, are essential for ensuring connection reliability. Use digital testers and follow standard procedures to verify every crimp meets minimum requirements.
