Q

PSU Drying Equipment Selection

A

PSU drying equipment is an investment, not a cost; dew point -30°C is a hard indicator; the long drying time of 5~7 hours must be guaranteed.; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence

Material Drying PSU; drying equipment; dew point; vacuum dehumidification; hot air circulation; moisture

Q

PSU Multi-stage Injection Air Entrapment

A

PSU high-speed process must be paired with multi-stage control; air entrapment treatment emphasizes both venting and profile; junctions are the key areas of concern.; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence
