How to prevent Nylon Coated Flange Plate from peeling or cracking due to overload or improper operation during use?

Nylon Coated Flange Plates excel in industrial applications due to their excellent corrosion resistance, wear resistance, and low coefficient of friction. However, if the nylon coating peels off or cracks due to overload or improper operation during use, it will not only affect its performance, but may also shorten its service life. Here are some detailed preventive measures and operating suggestions to help you effectively avoid these problems.

Understand the performance limitations of nylon coatings
Load capacity
Before installation and use, be sure to understand the design load range of nylon coated flange plates. Avoid exceeding its load-bearing capacity, otherwise the coating may peel off due to excessive extrusion or stretching.
If the flange plate needs to withstand high loads, choose a thicker nylon coating or switch to reinforced nylon materials (such as glass fiber reinforced nylon).
Temperature range
Nylon materials generally have a temperature resistance range of -40°C to 120°C (depending on the material type). If exposed to an environment that exceeds its temperature resistance limit for a long time, the nylon coating may become brittle or soften, resulting in cracking or peeling.
When used in high or low temperature environments, ensure that the operating temperature of the flange plate is within its design range.
Chemical compatibility
Nylon is sensitive to certain chemicals, such as strong acids, bases, or organic solvents. If the flange plate is exposed to incompatible chemicals, the coating may swell, dissolve, or crack.
When selecting a nylon-coated flange plate, confirm whether it is suitable for the specific working environment and avoid contact with incompatible media.
Proper installation and operation
Avoid overtightened bolt connections

When installing the flange plate, the tightening torque of the bolts should meet the design requirements. If the bolts are overtightened, the flange plate may be deformed, which will exert excessive stress on the nylon coating, causing peeling or cracking.
Use a torque wrench to control the tightening torque of the bolts to ensure uniform force.
Prevent shock or vibration
Nylon coatings are sensitive to strong mechanical shock or continuous vibration. If the flange plate is hit or vibrated frequently, the coating may crack or fall off.
In high-vibration environments, consider adding shock absorbers or choosing more durable coating materials.
Avoid scratches from hard objects
Although the surface of the nylon coating has a certain wear resistance, it is still necessary to avoid direct contact with sharp or rough objects. For example, avoid scratching the coating with tools or other parts during handling or installation.
Regular inspection and maintenance
Check coating integrity
Regularly check the surface condition of the nylon coating to observe whether there are signs of peeling, cracking or wear. If minor damage is found, it should be repaired in time to prevent further deterioration.
For severely damaged coatings, you can contact professional manufacturers for repair or replacement.
Cleaning and maintenance
Regularly clean the surface of the flange plate to remove dust, oil or other contaminants. When cleaning, use a mild detergent and soft cloth, and avoid using corrosive chemicals or hard brushes.
If the surface of the flange plate is stained with dirt that is difficult to remove, you can soak it in warm water and wipe it gently, and never scrape it hard.
Prevent long-term exposure to harsh environments
If the flange plate is exposed to direct sunlight, humidity or corrosive environments for a long time, the nylon coating may age faster. Its life can be extended by adding a protective cover or applying a protective agent regularly.
Improve the working environment
Control humidity
A high humidity environment may cause corrosion of the metal substrate, thereby weakening the adhesion of the nylon coating. The impact of humidity can be reduced by dehumidification equipment or coating sealing treatment.
Avoid direct UV exposure
Ultraviolet rays accelerate the aging of nylon materials, causing the coating to become brittle or crack. If the flange plate needs to be used outdoors, a modified nylon coating with UV resistance can be selected.
Reduce friction and wear
In sliding parts or bearing applications, nylon coatings may wear due to long-term friction. Wear can be reduced by regular lubrication or by selecting nylon materials with higher wear resistance.

Scientific operating habits and maintenance measures can not only extend the service life of nylon coated flange plates, but also ensure their stability and reliability in industrial applications.
