EVT-522 Fully Automatic Dual Pair Twisting & Waterproof Seal Insertion & Terminal Crimping Machine (4 Wires, 2 Groups, Staggered Equal Length) | Automatic Wire Crimping Machine

Model: EVT-522 (Wire Harness Processing Equipment)

The EVT-522 is an advanced, high-performance Fully Automatic Dual-Pair Wire Processing Machine engineered for high-efficiency wire cutting, stripping, twisting, waterproof seal insertion, and terminal crimping in a single automated cycle. Powered by high-precision servo drives, it ensures extreme dimensional accuracy, firm wire twisting without copper scattering, and integrated inline quality inspection to significantly minimize rework rates.

Designed for heavy-duty industrial environments—particularly automotive harnesses, home appliance wiring, and electronic sensor cables—this machine features one-touch recipe storage for rapid model switching. It enables single-operator multi-machine management, saving labor costs, floor space, and maximizing mass-production output.

Key Features of the EVT-522 Fully Automatic Dual Pair Twisting & Waterproof Seal Insertion & Terminal Crimping Machine (4 Wires, 2 Groups, Staggered Equal Length)

• All-in-One Multi-Process Integration: Combines wire cutting, stripping, dual-pair twisting, waterproof seal insertion, and terminal crimping into one seamless workflow, replacing multiple standalone machines.
• Flexible Staggered & Equal Length Processing: Capable of handling both synchronized equal-length wire pairs and complex staggered length configurations (such as front alignment with customizable back offsets) to suit rigorous wiring harness specifications.
• High-Precision Servo Control: Driven by advanced servo systems to guarantee precise cutting lengths, minimal stripping errors, and exact positioning via high-precision lead screws.
• Flawless Twisting Technology: Ensures uniform, tight twisting for 4 wires across 2 groups without loose strands or copper wire scattering, preventing terminal defects.
• Comprehensive Inline Quality Inspection: Equipped with multiple intelligent monitoring functions, including blade-to-core touch alarms, terminal vision inspection (stripping length verification), crimp force monitoring, and wire-end detection with automatic bad-part sorting.
• Rapid Recipe Switchover: One-touch storage and loading of technological parameters reduces format changing time by up to 70%.
• High Production Efficiency & Labor Saving: Delivers high-speed mass production with intuitive operation, allowing a single operator to manage multiple units and drastically slash labor expenses.
