Airtight Gauge Case is an engineered protective case in the instrument case family: built by source factory kexinMaterials with IP67 sealing, impact-resistant PP copolymer or rotomolded PE shells and CNC-cut custom foam; wholesale, OEM and export supported.
An instrument case protects precision measuring and testing equipment in transit, emphasizing shock absorption, moisture resistance and custom foam so instruments stay calibrated between lab and field.
Airtight Gauge Case: Product & Manufacturer Overview
The Airtight Gauge Case can be tailored to your brand and project: case color, silk-print or laser-engraved logo, foam layout and handle/wheel options are all adjustable. kexinMaterials, as the source factory, runs the whole journey from sample approval to mass production, including neutral shipping and OEM private label.
From total stations and spectrometers to flaw detectors, kexinMaterials has built the Airtight Gauge Case for thousands of instrument models, with an insert database spanning surveying, environmental monitoring, NDT and telecom engineering.

Standards & Industry Data
Shell Materials Compared (PP / ABS / PE)
Industry data puts PP (polypropylene) at ~55% of plastic protective-case share — strong chemical resistance, low-temperature toughness and cost efficiency; ABS holds ~30% with harder, glossier surfaces; large thick-wall cases favor rotomolded PE. Plastic/polymer cases together account for 63.7% of the industrial protective case market (2025).
Extreme Temperature Performance
Engineering-grade cases typically operate from -30°C to +80°C (military testing follows MIL-STD-810H Methods 501.7/502.7 for temperature and 503.7 for thermal shock, cycling as wide as -40°C↔+71°C). For cold climates choose PP copolymer or PE shells — standard ABS embrittles at low temperatures.
IP Ratings (IEC 60529)
In IP67, the “6” means dust-tight (no dust ingress after a 2 kPa vacuum dust test) and the “7” means temporary immersion: the enclosure survives 30 minutes at 1 m depth with its highest point at least 150 mm below the surface, per IEC 60529 Clause 14.2.7.
Typical Applications
- Surveying instrument field carry
- Third-party lab on-site sampling
- Metrology equipment calibration logistics
- Fiber-optic construction toolkits
- Laboratory relocation and equipment loans
- Manufacturer co-packing programs
Product Overview
The kexinMaterials Airtight Gauge Case is one-piece molded from engineering plastics, balancing impact strength, sealing and long-term durability — available from stock or fully customized. Key specs below.
On process: the Airtight Gauge Case can be injection, rotational or blow molded. Injection gives precise sealing and repeatability; rotomolding yields large seamless shells with thick-wall toughness; blow molding suits light, economical builds. kexinMaterials runs all three lines and matches the process to your protection grade and budget.
For interior protection, the Airtight Gauge Case ships with or accepts CNC-cut EVA/PE foam, routed to your equipment's 3D data so nothing shifts in transit; precision instruments can add ESD-safe or cushioned layered structures.
On quality, the Airtight Gauge Case passes batch drop, stack and immersion checks; key models can be tested to MIL-STD-810H for drop and vibration, with material and third-party test reports supplied for export and industry acceptance.
Manufacturing Process
High-pressure injection molding keeps shell tolerances tight for reliable sealing, and inserts are CNC-cut after drop-simulation checks. Volume co-packing projects follow a PDI inspection routine so cushioning performance stays consistent across batches.
Field Case Studies
600 anti-static liner cases for precision calibrators using non-shedding XLPE; zero scratch incidents in annual off-site checks.
3,000 cases CNC-cut to probe shapes, thermal-shock verified -40°C↔+71°C, protecting gear across overseas expos.
