company news about The spraying parameters for different materials

The spraying parameters for different materials typically differ in the following aspects:

1. Spraying Voltage

• Metal Workpieces: Usually require a higher voltage to ensure good powder adhesion.
• Plastic Workpieces: Lower voltage is preferred to avoid overheating and damage.

2. Spraying Distance

• Metal Workpieces: The spraying distance is generally shorter to enhance the uniformity of the coating.
• Plastic Workpieces: A slightly longer spraying distance can be used to prevent local overheating.

3. Powder Flow Rate

• Metal Workpieces: A higher powder flow rate is necessary to ensure sufficient coating thickness.
• Plastic Workpieces: A moderate flow rate is used to avoid excessive powder accumulation.

4. Curing Temperature and Time

• Metal Workpieces: Curing temperatures are usually higher, and the time is longer to ensure complete curing of the coating.
• Plastic Workpieces: Lower curing temperatures and shorter times are used to prevent deformation of the material.

5. Pre-treatment Methods

• Metal Workpieces: Typically require rust removal and degreasing to enhance adhesion.
• Plastic Workpieces: May need special surface treatments, such as sandblasting or chemical treatments.

These parameters can be adjusted based on the specific workpiece material, type of coating, and production requirements to achieve the best coating results.
