Famous Chinese Brand BOZWANG Releases Ultrasonic Wire Harness Welding Machine

Jiangsu Bozhiwang Automation Equipment Co., Ltd.—better known worldwide as BOZWANG—has officially expanded its special-application portfolio with a new generation of ultrasonic wire harness welding machines. The release covers the BZW-9A, BZW-9A-02, BZW-9B, and BZW-9C platforms, positioning BOZWANG as one of the few Chinese wire-harness equipment brands able to deliver crimping, cutting-stripping, FAKRA/HSD/Ethernet lines, EV high-voltage processing, and ultrasonic metal welding from a single source factory.

The message to the market is simple: stop relying on crimping and tinning alone—move to zero-resistance, flux-free, traceable copper and aluminum joints.

Why This Launch Matters

Traditional terminal crimping and tin-dipping have served the industry for decades, but they introduce third-party metals, thermal stress, flux residue, and long-term heating risk. In EV batteries, energy storage, 5G/automotive communication harnesses, and high-current control systems, those weaknesses matter.

BOZWANG's ultrasonic welder uses a 20 kHz stable acoustic system to create a solid-state metallurgical bond. There is no solder, no flux, no smoke, and no added contact resistance. The result is a copper-to-copper or copper-to-aluminum joint with near-zero ohmic loss and excellent pull-force consistency.

For buyers, the value is not only the joint quality. It is the combination of:

• factory-grade repeatability,

• recipe-driven changeover,

• MES-ready data,

• portable and bench models in one product family,

• and source-factory pricing from a Chinese brand with global export experience.

The Product Family

BZW-9A — Bench / Industrial Wire-to-Wire Welder

Designed for copper-wire docking and parallel pressure welding. Typical specs include 0.75–20 mm² or wider 0.5–25/50 mm² variants, 3000 W / 2600 W / 5000 W power options, 20 kHz frequency, industrial-PC or touchscreen HMI, recipe storage, and MES uplink. It replaces terminal crimping or tin dipping with direct ultrasonic bonding.

BZW-9A-02 — Portable Ultrasonic Welder

A split-type, 33 kg unit at 620 × 230 × 250 mm, 2000 W, 0.5–10 mm² range. It shares the same weld-energy algorithm as stationary BOZWANG units, so a bench operator and a floor operator get consistent results without recalibration. Ideal for service centers, R&D labs, EV retrofit shops, and small-batch production.

BZW-9B / BZW-9C — Ultrasonic Terminal Welders

Focused on wire-to-terminal applications for automotive, electronics, and new-energy high-voltage assemblies. These models target strong, gap-free terminals with lower heating risk and cleaner process control than soldered joints.

Technology Highlights

In-house acoustic stack

BOZWANG develops transducer, booster, and horn with vertical integration, giving better consistency across shifts and batches.

Real-time process control

The controller monitors energy, power, pressure, and time. Weld data can flow to MES: every joint becomes traceable by timestamp, energy curve, and operator/batch ID.

Recipe management

Operators store formulas for different wire gauges and terminal types. Switching from 2 mm² signal wire to 35 mm² power cable is a recipe change, not a rebuild.

Clean, safe, energy-efficient

No flux, no tin, no harmful gas. Lower power draw than many resistance-welding methods. Safer for operators and better for green-manufacturing audits.

Precision at production speed

Standard systems handle roughly 120–150 welds/hour, with advanced platforms reaching 2–3 seconds per joint. Pull-test values stay consistent from first weld to last.

Why BOZWANG, Why Now

BOZWANG is not a trading company relabeling generic welders. The Changzhou base spans about 40,000 m² site / 45,000 m² building area, with 500+ employees, 300+ technical personnel, and 100+ invention patents plus hundreds of utility and design patents.

The factory already serves automotive communication, Ethernet, FAKRA/HSD, and EV high-voltage harness customers. Adding ultrasonic welding closes the loop: one supplier for prepare → strip → crimp → weld → test → trace.

For distributors, this is the key selling point: BOZWANG lets you sell the whole wire-harness process, not just one box.

Reseller and Wholesale Angle

Ultrasonic welders are becoming a high-repeat industrial category because:

• EV and energy-storage plants need flux-free copper/aluminum joints.

• Automotive harness shops want MES traceability.

• Electronics and appliance factories want cleaner alternatives to hand soldering.

• Portable models open service, repair, and training-market channels.

• Consumable-free welding reduces the buyer's hidden process cost.

A reseller can start with one BZW-9A bench unit, demo it with the customer's own wire, then upsell BZW-9A-02 portables, BZW-9B/BZW-9C terminal welders, crimping machines, cut-strip machines, and FAKRA/HSD lines.

Market Timing

The global ultrasonic welding machine market reached USD 2.4 billion in 2024 and is projected toward USD 3.7 billion by 2030. A single luxury car already contains 4,000+ connection points. As EVs, 800V architectures, battery packs, and high-speed data harnesses scale, the demand for reliable, traceable, low-resistance joints will keep rising.

BOZWANG's release is timed for exactly this shift: Chinese manufacturing quality, export compliance, smart-factory data, and factory-direct margins.

Bottom Line

BOZWANG's ultrasonic wire harness welding machine series is more than a product launch. It is a statement that a famous Chinese wire-harness equipment brand can deliver precision welding + intelligent data + global service in one ecosystem.

For automotive Tier-1s, EV battery plants, harness shops, and equipment resellers, the takeaway is clear: crimping got you this far—ultrasonic welding is the next decade of harness joining.
