Compact Instrument Case: 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.

From total stations and spectrometers to flaw detectors, kexinMaterials has built the Compact Instrument Case for thousands of instrument models, with an insert database spanning surveying, environmental monitoring, NDT and telecom engineering.

Key facts: Compact Instrument Case sourcing facts: factory-direct from Guangdong, China; sealing up to IP67; service range -40°C to +80°C; CNC-cut EVA interiors; logo printing/engraving; factory audits and third-party QC welcome.

Product Feature Breakdown

Compact / mini

The real constraint on small cases is usable interior: wall thickness and foam consume a large fraction of the cavity in Compact Instrument Case, so always compare internal dimensions rather than external. kexinMaterials lists both internal and external dimensions in every spec table.

Standards & Industry Data

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.

Military Vibration (MIL-STD-810H, Method 514.8)

Random-vibration testing spans 20–2,000 Hz to replicate truck, aircraft and battlefield vibration, run for hours per axis; transport spectra cover 2–500 Hz. Passing means the shell-plus-foam system protects precision payloads through long multimodal transit.

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 Compact Instrument 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 Compact Instrument 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 Compact Instrument 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 Compact Instrument 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

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.

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.

MOQ and lead time?

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

Will air freight pressure lock the case shut?

No. The automatic pressure equalization valve balances internal pressure while keeping the seal waterproof.

How do you keep instruments in calibration after shipping?

By interrupting the vibration path: high-density EVA is cut to the instrument profile so a 20–30 mm cushion separates it from the shell, with energy-absorbing foam underneath. For high-precision units we can add isolation mounts or a suspended insert to attenuate transport shock within the instrument's tolerance.

How is a custom insert made?

Send 3D data, dimensioned photos or a sample unit. We design the cutout layout, confirm an insert sample with you, then run production. Common models ship from existing data.

Key Terms Explained

EVA foam insert
Ethylene-vinyl acetate closed-cell foam: dense, resilient, CNC-machinable and resistant to permanent compression set. In protective cases it is cut to the equipment profile and is the preferred lining for precision instruments and high-value gear.
ESD / antistatic
Conductive masterbatch or antistatic lining brings surface resistance into the 10^6–10^9 Ω range so static cannot build up and damage electronics. It is a routine requirement in electronics manufacturing, semiconductor and precision instrument handling.
Injection molding
Molten plastic is injected under high pressure into a steel mold and cooled. It delivers tight tolerances, fine surface finish and fast cycles at low piece cost, but requires higher tooling investment — best for volume production of small and mid-size cases.

Common Misconceptions

Does less material make a small case cheap?

Unit price is lower but cost per kilogram is higher. Tooling, hardware, packaging and inspection for a small case are nearly identical to a large one, spread across far less material. This is why tooling amortisation dominates low-volume custom small cases — starting from a standard body with a custom insert is usually the better route.
