June 1, 2026 — KeXin New Materials (Guangdong) Co., Ltd. officially announces the global launch of the WL8442, the latest flagship model in the renowned 8-series protective case lineup. With an impressive 139.5-liter internal capacity, full IP67 dust and water protection, and a reinforced structural design purpose-built for transporting large precision equipment, the WL8442 sets a new benchmark for heavy-duty protective solutions in the global market.

Product Announcement: A New Standard in Large-Case Protection

The protective case industry has long faced a gap between standard transport containers and true engineered protection for oversized, high-value equipment. Conventional plastic crates lack sealing integrity. Metal enclosures add excessive weight. The WL8442 bridges this divide with a scientifically optimized PP (polypropylene) copolymer shell that delivers military-grade impact resistance at a fraction of the weight of aluminum equivalents.

KeXin's product development team invested 18 months in the WL8442 project, conducting over 200 physical drop tests across six impact orientations, accelerated weathering cycles simulating 10 years of outdoor exposure, and extensive field trials with beta customers in the medical imaging, broadcast, and industrial NDT sectors. The result is a case that not only meets but exceeds the expectations of the most demanding professional users.

IP67 Triple Waterproof Architecture

The WL8442 achieves its IP67 rating through a three-layer sealing architecture that goes far beyond simple gasket placement:

  • Primary seal: A continuous silicone rubber O-ring seated in a precision-milled groove around the entire lid perimeter. The groove geometry ensures uniform compression across all 360 degrees, eliminating the weak corners that plague conventional press-in seals.
  • Secondary seal: An interlocking tongue-and-groove joint design between the lid and body halves. This mechanical interlock creates a labyrinth path that blocks water ingress even under prolonged submersion at 1-meter depth for 30 minutes, as required by IEC 60529.
  • Pressure equalization: An automatic pressure relief valve rated for differential pressures up to ±0.7 bar. The valve opens during air transport altitude changes to prevent vacuum lock, then reseals instantly when pressure normalizes — ensuring the primary and secondary seals never experience stress that could compromise their integrity.

Together, these three systems create a redundancy model: if any single seal element is compromised by wear or damage, the remaining layers continue to provide substantial protection. This architecture is why KeXin confidently submits every WL8442 unit for third-party IP67 certification testing, not just batch sampling.

Key Features and Technical Specifications

The WL8442 incorporates every engineering advancement KeXin has refined across 25 years of protective case manufacturing. Here are the standout features:

  • 139.5L Internal Capacity: Internal dimensions of 840 × 440 × 390 mm accommodate equipment from portable ultrasound systems to mid-size broadcast cameras. The generous depth allows stacked configurations with foam layer separators.
  • Automatic Pressure Valve: The integrated valve eliminates the common user error of forgetting to open manual valves before flights. Its one-way design also prevents water ingress during ground transport in rainy conditions.
  • CNC EVA Foam Liner: Custom-cut from 60 kg/m³ high-density EVA using five-axis CNC machining. The liner provides precise cavity contours matching equipment shapes, with 25mm minimum wall thickness between cavities for adequate cushion energy absorption.
  • Reinforced Corner Architecture: Each of the eight corners integrates a 6mm-thick PP rib matrix that absorbs and redirects impact energy away from the flat shell surfaces. Drop tests from 1.2 meters onto concrete show zero structural deformation at all corners.
  • Stainless Steel Latches: Four 304-grade stainless steel butterfly latches with 500N clamping force each. The latch mechanism includes a safety lock tab that prevents accidental opening during rough handling. Corrosion resistance exceeds 200 hours in salt-spray testing per ISO 9227.
  • Comfort-Grip Handles: Two ergonomic side handles with soft TPU over-mold on a steel core frame. The handle geometry distributes load across the entire palm, reducing fatigue during repeated lifts. A central telescopic trolley handle option is available for wheel-equipped configurations.

Customization Options

KeXin understands that no two equipment transport scenarios are identical. The WL8442 supports a comprehensive range of customization services that transform a standard case into a purpose-built solution:

  • Custom Color: Standard orange is available from stock. Custom colors can be matched to Pantone references or corporate brand guidelines. Minimum order for custom color is 50 units. Color is molded into the PP shell — not painted — so it cannot scratch off or fade.
  • Logo Printing: Silk-screen, pad printing, and thermal transfer options for single-color or multi-color logos. KeXin's in-house printing facility ensures precise color registration and durable adhesion tested to 500 rub cycles per ISO 105-X12.
  • Custom Foam Inserts: From simple rectangular cavity grids to complex multi-level contour cuts with pull-out tabs and accessory compartments. KeXin's foam engineers work from customer-provided CAD files or physical equipment samples.
  • Transparent Window Panel: An optional lid window allows visual inspection of contents without opening the case, critical for security checkpoints and inventory audits. The window is sealed with its own O-ring and rated IP65 when installed.
  • Trolley Wheel System: Two or four inline skate wheels with polyurethane tread for quiet operation on hard floors. The wheel mounting brackets are bolted through the case body with sealed gaskets, maintaining IP67 integrity even with wheels installed.
  • Equipment Panel Mount: For rack-mount electronics, KeXin offers front and rear panel frames that allow direct installation of 19-inch standard rack equipment inside the case. Panel rails are aluminum extrusion with adjustable depth.

Global Certifications and Compliance

The WL8442 carries a complete suite of international certifications that verify its safety, environmental compliance, and performance claims:

  • CE Marking: Conformity with EU Directive 2006/42/EC for machinery safety and relevant harmonized standards for transport enclosures.
  • RoHS Compliance: All materials and manufacturing processes comply with EU Restriction of Hazardous Substances Directive 2011/65/EU, verified through third-party analytical testing of all component materials.
  • REACH Registration: Full substance declaration available for all chemical constituents of the case shell, seals, latches, and foam. No SVHC (Substance of Very High Concern) above 0.1% threshold in any component.
  • IP67 Certification: Issued by SGS-CSTC Standards Technical Services Co., Ltd., a globally accredited testing laboratory. Each production batch undergoes random sampling verification.

Industry Applications

The WL8442's combination of large capacity and IP67 protection makes it the ideal choice across multiple professional sectors:

  • Medical Equipment: Portable ultrasound machines, patient monitoring systems, and field surgical instrument sets. The IP67 seal protects sensitive electronics from sterilization-area humidity and transport wash-down procedures.
  • Industrial NDT (Non-Destructive Testing): X-ray fluorescence analyzers, ultrasonic flaw detectors, and thickness gauges. These instruments often operate in harsh industrial environments where oil, dust, and water exposure is routine.
  • Telecommunications: Base station test equipment, fiber optic splicing kits, and spectrum analyzers deployed to remote installation sites. The automatic pressure valve is essential for equipment flown to elevated tower locations.
  • Broadcast and Media: Professional video cameras, lens kits, and field lighting systems. The reinforced corners protect against the rough handling common in live-production logistics.
  • Military and Defense: Tactical communication equipment, portable radar modules, and field medical kits. KeXin's 8-series cases meet multiple defense procurement specifications for non-classified equipment transport.
  • Aviation: Ground support test instruments, cockpit component shipping, and avionics transport. The case's low weight relative to metal alternatives directly reduces air freight costs.
  • Marine: Ship maintenance instruments, underwater camera housing transport, and offshore platform equipment. IP67 submersion resistance is essential for marine logistics where cases may be exposed to seawater splash or temporary immersion during boat transfers.
