Quzhou Intel Polymer Materials Co.,Ltd.

This company has been a long-time customer of our distributor—we’ve known each other for over a decade, and there is a strong foundation of mutual trust and familiarity. With the active efforts of our Quzhou distributor, we jointly built the brand new first "Class 1 Energy Efficiency Compressed Air Station" in Quzhou, which is of great significance.

Shaoxing Youjing Photo Frame Manufacturing Co., Ltd.

As a photo frame manufacturer, the company strictly controls production because every step affects product look and durability. However, the original air compressors and dryers had high oil and impurities. During chamfer cleaning with air blowing, stubborn oil stains remained, causing frequent quality problems. Products didn’t meet customer standards, leading to many reworks.
