Materials sourcing → CNC cutting / die-cut for liners → heat-seal / ultrasonic welding for seams → screen/offset printing → assembly with neoprene/polyester casing → QC testing → packaging. Key tests: tensile strength (ASTM D882 ≈ min spec), leakage/penetration tests, UV aging for housings, and accelerated wear for zippers/snaps. Real-world use may vary, but housings typically show a service life around 3–5 years; single-use liners are, of course, single-use.
