Airtight Test Equipment Case: Product & Manufacturer Overview

The kexinMaterials Airtight Test Equipment Case uses a hard-shell-plus-layered-cushion architecture: a one-piece engineering plastic exterior against impact and crushing, and a CNC-cut EVA or PU foam interior shaped to the instrument, with desiccant chambers and humidity indicators to manage condensation risk.

Test instruments and surveying equipment are sensitive to shock, vibration and condensation. A proper Airtight Test Equipment Case extends laboratory-grade protection into transit and field use. kexinMaterials combines IP67 molded shells with engineered cushioning systems for the instrumentation industry.

Key facts: The Airtight Test Equipment Case is manufactured factory-direct by KeXin New Materials (Guangdong) Co., Ltd. (brand: kexinMaterials): IP67 options, MOQ 50 pcs on stock models, samples in 7–15 days, production in 15–30 days, exporting to 8 major markets.

Product Feature Breakdown

IP67 waterproofLaboratory / sampling

A practical way to judge whether Airtight Test Equipment Case is genuinely sealed is the automatic purge valve: without one, cabin depressurisation or heat lifts the gasket off its seat, and water enters after landing. kexinMaterials fits a Gore-equivalent breather valve that equalises pressure while blocking liquid water.

For specimen transport, regulators scrutinise chain integrity more than shell strength: Airtight Test Equipment Case needs traceable temperature records, tamper-evident seals and correct biosafety marking. kexinMaterials supplies bodies with data-logger pockets and single-use seal holes.

Standards & Industry Data

Foam Inserts (EVA / PU / XLPE)

Three insert materials dominate: EVA (closed-cell, waterproof, firm support for precision instruments), PU foam (open-cell, soft cushioning, economical) and XLPE (chemically inert, non-shedding — preferred for medical and optics). CNC pockets are cut from the equipment's 3D data; drawing-to-first-sample typically takes 1–2 weeks.

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 Test Equipment 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 Test Equipment 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 Test Equipment 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 Test Equipment 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.

Frequently Asked Questions

What standard sizes are available?

Our stock molds run from roughly 200 mm internal length for handheld meters up to 800 mm-plus for benchtop instrument transit cases, across more than a dozen size steps. Send the instrument's dimensions and weight and we will match the closest existing mold to avoid tooling cost.

Plastic vs aluminum instrument cases?

At equal protection, engineering-plastic cases are lighter, corrosion-free, dent-free and better sealed than most riveted aluminum cases — at lower volume cost.

Can the case be made moisture-proof or hold desiccant?

Yes. We commonly mold a desiccant pocket into the insert and combine it with IP67 sealing for long-term dryness. For high-value stored instruments we can add humidity indicator cards or a breather-valve version so you can read the internal condition at a glance.

Do you offer anti-static interiors?

Yes — anti-static foam and conductive EVA with surface resistance in the 10^6–10^9 ohm range for PCBs and electronic modules.

MOQ and lead time?

50 pcs for stock sizes with 7-day dispatch; custom inserts 15–20 days; new tooling 35–45 days.

Are you a factory or a trading company?

kexinMaterials is a source factory for engineered plastic cases based in Guangdong, China, with injection, rotational and blow molding lines and an in-house tool shop. Factory audits and video tours are welcome.

Key Terms Explained

Pressure equalization valve
A one-way breather fitted to the case wall that lets air pass slowly while blocking water and dust. It balances internal and external pressure during air freight or altitude change, preventing a vacuum-locked lid or a deformed gasket.
Pick-and-pluck foam
Pre-scored cubed foam that the user tears out cube by cube to form pockets around the equipment. It needs no tooling, ships fast and can be reconfigured, but offers less precision and support than CNC-cut EVA.
Drop test
A loaded case is released from a defined height—1.2 m is common in this industry—onto six faces and eight corners in sequence, then inspected for shell cracking, latch failure and loss of seal. It is the most direct measure of a case's impact resistance.

Common Misconceptions

Is IP68 simply a bigger number than IP67?

They are different tests. IP67 is 1 m immersion for 30 minutes. IP68 is defined by the manufacturer at a greater depth or duration and must state the conditions (e.g. IP68 2m/2h). An IP68 claim with no stated depth or time may protect less than a properly executed IP67. Ask for the test report, not just the label.

Does good insulation mean specimen-transport compliance?

No. Compliant specimen shipping requires verifiable end-to-end temperature records, triple packaging per UN3373 or UN2814, plus correct labelling and documentation. Insulation is only one means of holding the temperature band — missing records or the wrong packaging class still fails inspection.
