As a technology-driven enterprise in the coating industry, Dongguan Paint Brother Spraying Equipment Technology Co., Ltd. focuses on technological innovation as its core engine, establishing its own processing lines to achieve precise manufacturing and quality control. The company has assembled a team of experienced industry professionals, built a cutting-edge R&D platform, and introduced technologies that have won numerous national patents and certifications. Its independently developed liquid and powder spray guns effectively address industry pain points such as low efficiency, high costs, and technological bottlenecks. Currently, the company's products are widely used in automotive parts, home appliances and furniture, building materials, and new energy industries, helping customers achieve efficient, energy-saving, environmentally friendly, and intelligent upgrades. In the future, we will continue to explore the boundaries of technology and lead the innovative development of the industry.
The black metal part, which the customer painted using a regular spray gun, shows obvious orange peel, graininess, and poor leveling on its surface. These are common painting defects.
Rotary cup spray guns use centrifugal force generated by high-speed rotation to atomize the paint more evenly and finely, resulting in a very smooth coating surface.
It has higher spraying efficiency, and its paint utilization rate is 2-3 times that of ordinary spray guns, which can save on paint costs.
The powder rotary spray gun utilizes a centrifugal + electrostatic composite atomization technology and is equipped with spiral/golf ball quick-release nozzles, making it adaptable to various powder types and spray patterns. Powder and parts replacement is convenient, and it supports intelligent process control, achieving high powder transfer efficiency and precise spraying in hard-to-reach areas, perfectly matching the pace of batch production and product changeovers.
With the support of high-speed centrifugal atomization technology, the film thickness deviation is ≤±5μm, completely eliminating the problem of "thick in the middle and thin on the sides."
The paint application rate increased to over 60%, reducing paint costs by 40%; paint mist emissions were reduced by 80%, easily meeting standards with zero additional investment.
The core unique selling point of the rotary cup spray gun lies in its dual core technologies of "high-speed centrifugal force + electrostatic adsorption," which enables a qualitative leap in spraying performance.
With the combined technologies of high-speed centrifugation and electrostatic adsorption, we overcome the challenges of coating complex curved surfaces and intricate details of lighting fixtures, achieving complete coverage without blind spots, resulting in a uniform and delicate paint film, and ensuring precise and consistent quality in mass production.
It can seamlessly integrate with robots to achieve 24-hour automated continuous operation, eliminating reliance on manual labor and reducing labor costs and operational risks.

Key factors include material viscosity, production volume, spray precision requirements, and the type of coating to be applied.
Daily cleaning after use is essential; deep maintenance (e.g., seal replacement) is recommended every 1–3 months depending on usage frequency.
It depends on the equipment type. Most professional sprayers work for multiple coatings, but thorough cleaning is required between material changes to avoid cross-contamination.
Common causes include clogged nozzles, unstable air pressure, incorrect nozzle distance from the surface, or worn-out spray gun components.
