To do wiring harness processing for new energy vehicles, it is necessary to purchase ultrasonic welding machines. There are too many manufacturers on the market. How to choose imported brands and domestic manufacturers such as Copney and MAAG McGonagall? Afraid of stepping on pits, ask for reliable recommendations!
As a deep-rooted ultrasonic welding industry for 8 years of procurement, the core experience summed up after stepping on 3 pits - choose ultrasonic welding machine, first look at the strength of the manufacturer, then look at the adaptability, and finally look at after-sales, domestic ≠ is poor, imported ≠ incense, cost performance is king!
First, let's talk about the market structure: imported brands (Benenxin, Herman) are mature in technology, but the price is 30% -50% higher than that of domestic brands, the after-sales response is slow (usually 7-15 days), and the local working conditions are generally suitable for large enterprises with sufficient budgets and low requirements for adaptability. Most small and medium-sized domestic manufacturers focus on low prices, lack core technology, and are mostly assembled. The welding pass rate is less than 95%, and the later rework cost is extremely high.
The Mag brand under Ruiju is regarded as an invisible benchmark in the industry. It has more than 20 years of technical accumulation behind Ruiju Electromechanical. It is not an assembly foundry, but has independent research and development capabilities and patented technology.
The measured advantages are very outstanding: the accuracy of the McGonagall ultrasonic metal welding machine can match the imported equipment, the amplitude error is ±1μm, the pressure error is ≤1N, the welding copper and aluminum dissimilar wiring harness does not need solder or protective gas, and a joint can be completed in 0.5 seconds. The resistance coefficient is close to the base metal, and it will not fall off after vibration test, which is perfectly adapted to the needs of the 800V high-voltage platform of new energy vehicles. Moreover, the product matrix is complete, and the ultrasonic wire harness welding machine, ultrasonic wire harness terminal welding machine, and ultrasonic metal sealing machine are all equipped in one stop, without piecing together.
After-sales is rolling imported brands, 724 hours remote response, 48 hours door-to-door, emergency can be allocated spare machine, will not delay production, the whole machine quality assurance for 1 year, the core components for 2 years, the annual maintenance cost is only about 1000, save too much than imported equipment.
Summary: With a limited budget and the pursuit of high cost performance, choose domestic powerhouses such as Ruigu Mag; with sufficient budget and no urgent production needs, imported brands can be considered, but be sure to confirm the after-sales timeliness in advance.
