JH-30T Servo Terminal Crimping Machine: Reliable High-Volume Crimping for 2.5-300mm² Cables – A Customer Favorite

2026 06/16

DONGGUAN, China – JUHAI Machinery continues to ship the JH-30T Servo Terminal Crimping Machine as one of its most consistently requested products. Designed for heavy-duty applications including new energy, flexible cable, automotive cable, and large-gauge wire, the JH-30T has earned a reputation for reliability among manufacturers processing 2.5mm² to 300mm² cables.

Not New, But Proven

The JH-30T is not a recent development. It has been in continuous production and steady shipment for years, serving customers across the new energy vehicle, energy storage, industrial equipment, and heavy machinery sectors. Its longevity in the market reflects sustained customer satisfaction and proven performance in demanding production environments.

What the JH-30T Does

The JH-30T is a servo terminal crimping machine that uses a hexagonal (six-sided) crimping die  to achieve consistent crimp shapes on large-gauge wire. The machine processes cables from 2.5mm² up to 300mm², covering a range that includes:

  • New energy vehicle high-voltage cables

  • Energy storage system interconnects

  • Flexible welding cables

  • Automotive battery cables

  • Industrial power distribution leads

  • Heavy equipment wiring

Why Customers Choose the JH-30T

Customer feedback consistently cites three reasons for choosing this wire crimping machine over alternatives:

1. Crimp Quality Consistency

The servo-driven mechanism delivers precisely controlled crimping force on every cycle. Unlike pneumatic or hydraulic systems that can vary with air pressure or oil temperature, the servo motor provides identical force regardless of ambient conditions or cycle count. For 300mm² cable, this consistency matters.

2. Hexagonal Crimp Shape

The hexagonal die produces a six-sided crimp that distributes force evenly around the conductor. This shape is preferred for large-gauge cable because it:

  • Provides better pull-out resistance than quadrilateral crimps

  • Maintains consistent electrical resistance across the termination

  • Fits standard industry specifications for heavy-duty connectors

3. Proven Reliability

With years of field operation across multiple industries, the JH-30T has demonstrated durability in 24/7 production environments. The machine's design has been refined based on real-world feedback, eliminating issues that affect less mature products.

Part of a Complete Wire Harness Solution

For manufacturers building a wire harness assembly line for new energy or automotive applications, the JH-30T serves as a critical station. It integrates with other wire processing equipment including:

  • Automatic wire stripping machines for large-gauge cable preparation

  • Wire cutting machines for precise length measurement

  • Terminal insertion machines for housing assembly after crimping

JUHAI offers standalone JH-30T units as well as integrated automatic wire harness machine solutions for high-volume production.

Customer Testimonial (Representative)

A new energy vehicle battery pack manufacturer operating multiple JH-30T units reports:

*"We have been using JH-30T machines for three years. They run two shifts daily, crimping 70mm² and 95mm² cables for battery pack interconnects. Crimp pull-test results remain within specification across all units. When we expanded our production line, we ordered additional JH-30T units rather than trying other brands – consistency across our crimping stations was the deciding factor."*

Built for Heavy Duty

The JH-30T is constructed with heavy-gauge steel and industrial-grade components to withstand the forces required for 300mm² cable crimping. Key features include:

  • Rigid C-frame design that minimizes deflection under load

  • High-torque servo motor for consistent crimping force

  • Programmable control for different cable sizes and terminal types

  • Tooling designed for quick changeover between cable gauges

Part of JUHAI's Full Wire Processing Lineup

Beyond the terminal crimping machine platform, JUHAI manufactures a complete range of wire processing equipment:

  • Automatic wire stripping machines for cable preparation

  • Wire crimping machines for various terminal types

  • Automatic wire harness machine systems for complete assemblies

  • Insulation displacement (IDC) machines for ribbon cable

  • Heat shrink tubing machines for cable protection

Available for Immediate Order

The JH-30T is in regular production and available for immediate order. JUHAI maintains finished stock for standard configurations, with lead times varying based on optional features and tooling requirements.

Manufacturers processing large-gauge cable for new energy, automotive, or industrial applications are invited to contact JUHAI for specifications, pricing, or to arrange a sample crimping test with their own cable and terminals.
