In May 2026, two sets of hot air circulation ovens manufactured by Changzhou Changhai Drying Equipment Co., Ltd. completed full quality inspection, air tightness test, temperature calibration and dust-free commissioning. The equipment was successfully loaded and exported to Vietnam, serving the standardized and refined drying processing of powder coatings for a local new materials enterprise.

As an environmentally friendly high-end coating material, powder coating is widely used in the surface spraying of hardware, building materials, home appliances and machinery. With fine particle texture and high sensitivity to moisture content, powder coatings are prone to uneven heating, surface crusting, internal moisture regain and powder agglomeration when processed by traditional drying equipment. These defects will cause spraying color difference, coating sagging and insufficient adhesion, greatly reducing the qualified rate of finished products. The Vietnamese client adheres to strict industrial standards for the drying uniformity, powder looseness and finished product stability of powder coatings.

Optimized exclusively for powder coating processing, the delivered hot air circulation ovens adopt a forced closed-loop hot air circulation system and optimized air duct distribution design. The internal temperature difference is stably controlled within ±2℃, eliminating drying dead corners and realizing full-area constant-temperature drying. Equipped with an intelligent PID temperature control system, the equipment can accurately adjust drying temperature and duration according to material characteristics. It ensures uniform temperature rise and precise temperature control, effectively avoiding high-temperature deterioration and agglomeration, and maintaining consistent moisture content and loose powder texture for each batch of products.

Made of high-quality stainless steel with a fully closed structure, the ovens prevent external dust and impurities, avoid secondary material pollution, and fully meet the clean production standards for industrial coatings. Compared with traditional drying equipment, the machines reduce energy consumption by more than 30% with high thermal circulation efficiency, stable operation and convenient operation. They are perfectly suitable for large-scale, continuous and high-quality mass production of powder coatings.

With mature drying technology, reliable equipment performance and industry-oriented customized solutions, Changhai Drying has won wide recognition from Southeast Asian customers. The successful delivery of this Vietnam project further expands our overseas market layout in the new materials and coating industry.

In the future, Changzhou Changhai Drying will continue to focus on the segmented field of industrial powder drying, iterate equipment technology and optimize production processes. We will empower the high-quality development of the global new materials and fine chemical industries with high-grade industrial drying equipment and comprehensive after-sales service system.
