Large Sensor Case: confirm internal dimensions first (equipment size plus foam allowance), then protection rating (IP67 is the benchmark) and shell material (PP for value, ABS for surface hardness, rotomolded PE for large sizes). Custom sizes available via tooling.
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.
Large Sensor Case: Product & Manufacturer Overview
Test instruments and surveying equipment are sensitive to shock, vibration and condensation. A proper Large Sensor Case extends laboratory-grade protection into transit and field use. kexinMaterials combines IP67 molded shells with engineered cushioning systems for the instrumentation industry.
For buyers, the true cost of a Large Sensor Case is more than unit price: carton specs shape freight, and spare parts and replenishment shape long-term use. kexinMaterials optimizes container loading and ships wear-part kits with volume orders to lower your total cost of ownership.

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 |
Large-format note: cases over 800 mm per side are best rotomolded — seamless walls, high tear resistance — and should add wheels, forklift channels and multi-person handles.
Standards & Industry Data
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.
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).
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.
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
Sizing & Selection Guide
To size a Large Sensor Case, measure the largest 3D dimensions of the payload and allow 30–50 mm per side for foam, then match against internal case dimensions. Above 30 kg payloads, add wheels and reinforced bases.
kexinMaterials stocks a full size run from personal cases to large transit trunks with published internal dimensions; if nothing fits, we evaluate mold revisions or new tooling — selection advice is free.
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
