Waterproof Testing Instrument Case Direct Factory: buy factory-direct. kexinMaterials manufactures in Guangdong, China with tiered wholesale pricing, samples-first policy and OEM branding — stock models ship fast, custom tooling on controlled lead times.
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.
Waterproof Testing Instrument Case Direct Factory: Product & Manufacturer Overview
For instrument manufacturers, kexinMaterials runs co-packing programs — we develop a dedicated case and insert from your 3D data and ship in neutral or branded form, lowering warranty damage rates while unifying your delivery image.
The kexinMaterials Waterproof Testing Instrument Case Direct Factory 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.

How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|
| Protection | IP67, thermal-shock verified -40°C↔+71°C | Plain cases fail thermal shock |
| Damping foam | EVA/PU/XLPE CNC-cut to instrument shape | Generic foam under-cushions |
| ESD & clean | Optional anti-static liner, non-shedding XLPE | Sheds debris onto optics |
| Rigidity | ABS high surface hardness, high crush strength | PP softens under stacking |
| MOQ | From 50 pcs, non-standard sizes toolable | Often 500 pcs min |
| Certification | Drop/vibration test reports provided | Incomplete docs |
Waterproofing: rated IP67 — fully dust-tight and leak-free after 30 minutes at 1 m depth. Sealing relies on a continuous silicone gasket in a molded rim channel, plus an automatic pressure valve so the case opens normally after rapid pressure changes.
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
Wholesale & Bulk Buying Guide
kexinMaterials prices the Waterproof Testing Instrument Case Direct Factory in volume tiers — 50 / 200 / 500 / 1000 pcs — with annual contract rates above 1000 pcs. Stock models dispatch from our Guangdong factory within 48 hours; custom builds follow the production schedule.
When buying the Waterproof Testing Instrument Case Direct Factory in bulk, look beyond unit price: carton specs (freight cost), spare-part policy (latches, wheels) and replenishment lead time all shape landed cost. kexinMaterials optimizes container loading and ships wear-part kits with volume orders.
Factory-direct pricing on the Waterproof Testing Instrument Case Direct Factory removes middle-man margins. Factory audits, pre-shipment inspection and third-party QC are all supported, with formal sales contracts on volume orders.
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.
