Runs and sags are defects caused by applying too much paint in one area, causing it to succumb to gravity before it can set. This is a common problem that can be solved with properly set up spraying equipment. The primary cause is moving the spray gun too slowly across the part or holding it too close. Another cause is having the fluid flow rate set too high for the speed of application. An automated or robotic spraying equipment system from TIMS COATING is the ultimate solution. By programming the exact speed, distance, and flow rate, we can engineer a repeatable process where runs and sags are physically eliminated from the equation.

The choice between robotic and manual spraying equipment comes down to volume, complexity, and quality requirements. Manual spraying is ideal for low-volume, custom work where flexibility is key. However, it is inherently inconsistent. Robotic spraying provides absolute repeatability. A robot will follow the exact same path, at the exact same speed, with the exact same trigger points on every single part. This leads to a more uniform finish, reduced material waste (often a 15-30% savings over manual spraying), and higher throughput. For any medium- to high-volume production, a robotic spraying equipment system from TIMS COATING will provide a rapid and significant return on investment.

The gun is the most critical tool in any spraying equipment system. The main types are: 1. Conventional Air Spray: Uses high-pressure air to atomize paint. It offers fine control but has very low transfer efficiency (20-40%). 2. High-Volume, Low-Pressure (HVLP): Uses a high volume of low-pressure air for softer atomization, improving transfer efficiency (40-65%). 3. Airless: Uses high hydraulic pressure to atomize paint without air, ideal for fast application of heavy coatings. 4. Air-Assisted Airless: A hybrid that uses hydraulic pressure for atomization and a low-pressure air cap to shape the pattern, offering speed and quality. 5. Electrostatic: The most efficient type, which applies an electrical charge to the paint, dramatically increasing transfer efficiency (60-95%). TIMS COATING can integrate the ideal gun technology for your specific needs.

"Orange peel" is a common defect that makes a finish look like the textured skin of an orange. It is often caused by incorrect setup of your spraying equipment. The primary cause is poor atomization, meaning the paint droplets are too large when they hit the surface. This can be solved by increasing the atomizing air pressure or by reducing the fluid viscosity (thinning the paint). Another cause is applying the paint too dry, either by spraying from too far away or having the fan air pressure set too high. A consultation with a TIMS COATING process expert can help you tune your spraying equipment to eliminate this defect and achieve a perfectly smooth, "Class A" finish.
