All-Metal Industrial I/O vs. Plastic Glands: Engineering Submersion Sealing in 15.6″ IP67 Panel PCs
In high-pressure washdown environments—such as industrial meat processing lines, chemical compounding corridors, and beverage bottling plants—human-machine interfaces (HMIs) must withstand continuous exposure to heated caustic detergents and pressurized water sprays. While many industrial computers claim an IP65 or IP67 rating based solely on their front bezels, total enclosure survival during plant washdown cycles requires true
