Our spray coating production line cannot only improve the quality of yourproducts, but also reduce your costswhile being environmentally sustainable.
Hanging Furnace Spraying Production Line
Automated assembly line operation: Through fully automated loading, spraying, curing, and unloading processes, the daily processing area can reach 300-500 square meters, increasing efficiency by 2-3 times, replacing the intermittent operation mode of traditional manual spraying
Uniformity of electrostatic spraying: Using high-voltage electrostatic adsorption technology, the powder coverage rate reaches over 99%, and the coating thickness error is ≤ 0.05mm. It is suitable for blind spot spraying of complex shaped workpieces (such as support arms, irregular lamp heads, etc.)
Precision temperature control process: The temperature fluctuation of the curing furnace is controlled within ± 1 ℃ to avoid defects such as coating bubbles and orange peel, ensuring adhesion ≥ 10MPa, and salt spray testing with corrosion resistance exceeding 1000 hours


Plasma Cutting Machine
Cutting range: Can handle non-ferrous metals such as stainless steel, aluminum, copper, titanium, etc., with a maximum cutting thickness of 80mm (plasma mode)
Efficiency advantage: The cutting speed of thin plate carbon steel is 5-6 times faster than traditional oxygen cutting, with small thermal deformation and almost no heat affected zone
Precision control: Adopting an automatic height adjustment system to monitor arc voltage in real time, ensuring cutting accuracy of ± 0.3mm/10m
Intelligent function: supports arc signal detection, fault diagnosis, and remote monitoring, reducing manual intervention
Large CNC Bending Machine
Digital control: precise control of bending angle, bending force, and displacement is achieved through a numerical control system, with a machining accuracy of ± 0.1mm, meeting the requirements of complex shapes and high standard tolerances
Automated process: Integrating industrial grade touch screens and intelligent programming systems to achieve automated operations from parameter input to finished product bending, reducing manual intervention and increasing efficiency by over 30%
Process compatibility: capable of handling metal plates with thicknesses ranging from 0.5mm to 30mm (including stainless steel, aluminum, carbon steel, etc.), suitable for diverse needs from thin to thick plates


Laser Scribing Machine
Cutting accuracy: The laser cutting machine can achieve a cutting accuracy of ± 10 microns, far higher than traditional mechanical cutting (± 50 microns), ensuring the flatness of the battery cell edge and the stability of electrical performance
Thermal impact control: By precise control of laser energy, the width of the heat affected zone (HAZ) is less than 20 microns, reducing the conversion efficiency loss caused by thermal damage
High speed cutting: Laser cutting speed can reach 3-5 times that of traditional mechanical cutting, with a daily production capacity of over 100000 pieces per machine, significantly shortening the production cycle
Material compatibility: Supports cutting of various photovoltaic cells such as silicon wafers, thin films, and wafers, adapting to different thicknesses (such as 150-200 µ m) and sizes
Automatic string welding machine for photovoltaic modules
High precision positioning and detection: The image positioning accuracy reaches ± 0.1mm, combined with intelligent detection modules, the defect rate is less than 0.5%, and the yield rate is increased to over 99.5%
Low temperature welding technology: By precise temperature control, thermal stress is reduced to avoid hidden cracks and fragments in the battery cells, ensuring the mechanical strength and electrical performance consistency of the battery string after welding


Photovoltaic Module Laminating Machine
±1℃temperature control accuracy: Using ejector pin technology to achieve uniform heating, temperature fluctuations are controlled within±1℃, effectively avoiding bubbles, fragments, and battery cell displacement
Multi zone temperature control system: By precise temperature control in a vacuum environment, the EVA film is uniformly cured, and the flatness error of the layer is less than 0.5mm
High stability design: Key components such as vacuum pumps and heating plates have a lifespan of over 100000 hours and an average time between failures (MTBF) of over 5000 hours
Defect rate<0.5%: Through vacuum pressure control (accuracy ± 0.1MPa) and intelligent detection module, ensure that the laminated components are free of bubbles and delamination
