The most common model for "Long auto-pressure-valve-case Wholesale" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
All Long auto-pressure-valve-case Wholesale cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/m³). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
The shell is rated IP68 (submersible 5m / 30 min) ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -30 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
We maintain 200+ foam-cut reference designs for Long auto-pressure-valve-case Wholesale, covering camera bodies, drone kits, broadcast gear, military equipment, medical devices, and industrial tools. Send us your equipment list, we will match to the closest reference or draft a new layout free within 24 hours.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.

Standard wall thickness is 3.0-3.5mm. The 3mm walls pass IP67, the 3.5mm walls pass IP68. Wall thickness is measured at 4 points on every production batch and recorded in the lot certificate.
We use a stainless steel pin hinge (3mm diameter for small, 5mm for large) rated for 10,000 open/close cycles. Hinge caps are molded into the case body, not screwed on. The hinge pin is removable for foam service.
Standard foam set is 25mm base + 10mm convoluted lid foam, CNC-cut to 0.5mm tolerance. Total foam thickness 35mm. Custom foam thickness available: 15-50mm base, with or without anti-static (ESD) treatment.
Standard: IP67 (submersible 1m / 30 min). Premium: IP68 (submersible 5m / 30 min) available for select models with reinforced seals and pressure valve. All IP tests performed by SGS, TUV, or Intertek at our lab in Zhongshan.
Engineering-grade polypropylene (PP) for standard, PP + glass fiber (PP+GF) for heavy-duty. We also offer ABS, PC+GF, and PA66+GF30 for specific applications. Material certification included with every shipment.
