Case Study - A Tool Manufacturing Company in Ningbo

This company is based in Ningbo and specializes in manufacturing hardware tools, saw blades, and machinery. During market development, the Deman team identified the company's challenges in compressed air usage, which can reduce product quality, damage equipment, and increase energy consumption. 

Customer Challenges Before the Upgrade:

1. Poor air compressor configuration with almost no margin under full load

① Significant pressure fluctuations severely affect cylinder operation

② Reduced product accuracy and lower production efficiency

③ Continuously increasing energy consumption

2. Excessive moisture in workshop air

① Corrodes products, leading to higher defect rates
② Damages equipment, increasing maintenance costs

3. Delayed after-sales service impacts production efficiency

After identifying these issues, our sales team proactively reached out to the company. Upon gaining a detailed understanding of their situation, we leveraged our professional expertise to introduce Deman’s customized services—covering air pressure, air flow, and air quality.

Our sincerity and professionalism earned the company's trust, leading to a mutual agreement to cooperate.
