Ultrasonic Tinning Equipment: Eco-Friendly & High-Precision Tin Coating Solution

Traditional tinning processes heavily rely on chemical flux, often causing uneven coating, high defect rates and limited material adaptability — common pain points that restrict precision manufacturing. Our ultrasonic tinning equipment adopts advanced ultrasonic cavitation technology to optimize traditional tinning workflows. It delivers efficient, stable and eco-friendly tin surface treatment for various precision components, making it a cost-effective upgrade solution for global high-end manufacturers.

1. New Energy Industry

Suitable for battery tabs, PV glass electrodes, solar panel leads and new energy wiring harnesses. It effectively improves the conductivity and oxidation resistance of energy storage parts, boosting the overall safety and service life of new energy equipment.

2. Precision Electronics & PCB Manufacturing

Ideal for PCB pins, inductors, aluminum substrate heat sinks, connector terminals and enameled wire ends. It forms an even, dense tin layer on micro precision parts, eliminating cold solder joints and poor connection to guarantee stable electronic performance.

3. Automotive Electronics & Electrical Engineering

Widely used for automotive harness terminals, copper-aluminum busbars, switch contacts and sensor pins. It provides better conductivity and corrosion resistance than traditional crimping methods, ensuring long-term stable operation of automotive and industrial electrical systems.

4. Aerospace & Medical Precision Manufacturing

Featuring flux-free, residue-free and high-reliability performance, it meets strict manufacturing standards for aerospace components and medical electronic parts, delivering clean, stable and high-quality coating results.

5. Special Material Processing

This equipment breaks through traditional process limitations, enabling reliable tinning for hard-to-solder materials such as aluminum, copper, ceramics, glass and stainless steel. It also supports dissimilar material bonding including aluminum-copper and copper-glass combinations, facilitating your product and material innovation.

Using pure physical ultrasonic cavitation technology, the machine requires no chemical flux, pickling or pre-cleaning. It eliminates chemical residues and workpiece corrosion, fully complies with global environmental standards, and saves extra post-processing cleaning costs and time.

2. Superior Coating Quality & High Stability

Uniform ultrasonic vibration thoroughly removes surface oxides, creating a tight, smooth and bubble-free tin layer with no pinholes or peeling. The high-density coating greatly enhances the workpiece’s oxidation resistance, wear resistance and electrical stability for long-term service.

3. Cost-Effective & High Efficiency

It simplifies complicated pre-treatment and post-processing workflows, lifting production efficiency by over 50%. It also allows aluminum-to-copper material substitution, cutting raw material costs by nearly 80% without quality loss. Optimized procedures greatly reduce labor and auxiliary equipment investment for lower overall production costs.

4. Strong Material Compatibility & High Flexibility

It supports tinning for common metals (copper, aluminum, nickel, silver) and special materials (ceramics, glass, stainless steel). It adapts perfectly to micro parts, irregular workpieces and composite materials, solving key processing bottlenecks that traditional tinning machines cannot handle.

5. Durable & Low Maintenance

Built with corrosion-resistant and high-temperature resistant stainless steel housing, the machine fully protects internal ultrasonic transducers from high temperature and metal dust damage. It runs stably with low failure rates and long service life, effectively reducing daily maintenance expenses.

Simple & Standard Operation Steps

No professional technical skills are required. With simplified and standardized operating procedures, the machine supports fast setup and efficient mass production:
Step 1: Preheat Preparation Power on the device, set the working temperature to approximately 400℃, and preheat the tin pot for 15–20 minutes until the tin blocks fully melt into uniform liquid tin.
Step 2: Activate Ultrasonic System After the tin liquid temperature stabilizes, turn on the ultrasonic vibration module to generate stable cavitation.
Step 3: Tinning Processing Place pre-cleaned workpieces into the tin liquid. Ultrasonic vibration instantly removes surface oxides and completes uniform tin coating in a short time.
Step 4: Cooling & Completion Take out the workpieces and cool them naturally. The finished parts feature smooth, residue-free and firmly bonded tin layers, ready for direct assembly without secondary cleaning.
