Powder Coating Pre-treatment Equipment (Spray Tunnel)

The spraying wash type powder coating pretreatment is by using many spraying nozzles and circulation pump to spray chemicals onto the processed objects. This process is suitable for big production capacity requirement, such as in fully automatic powder coating line. The spraying tunnel normally requires 316L Stainless Steel to be fabricated, there for the investment is relatively high.

The processing of a basic spraying wash system mainly include degrease, conditioning, phosphate, rinse. Actual stages should be decided and built according to customer's products.
