IP67, MIL-STD-810H, ROHS, CE — the alphabet soup on Heat-resistant microphone-case marketing pages can be overwhelming. This page cuts through the noise. We publish every test result and every certificate we hold.
Below is the catalog data for Heat-resistant microphone-case. Each model has outer dimensions (in mm), inner cavity (mm), empty weight (g), and material specification. Material is engineering PP or PP+GF for impact resistance. Foam set is included: 25mm base + 10mm lid convoluted.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL1905 | 190×190×45 mm | 180×160×40 mm | 250 g | PP | Medium |
| WL2005 | 195×170×46 mm | 190×135×40 mm | 175 g | PP | Medium |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+GF | Extra Large |
The most common model for "Heat-resistant microphone-case" buyers is the WL1905 (190×190×45 mm OD, 250 g empty weight, PP body).
All Heat-resistant microphone-case cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/m³). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
Our Heat-resistant microphone-case buyers in 2024 include: 35% camera operators / filmmakers, 25% drone pilots / commercial UAS, 15% broadcast / TV stations, 10% military / law enforcement, 10% medical / first responders, 5% industrial / OEM. Profile data from 2024 buyer survey.
Cheap Heat-resistant microphone-case: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our Heat-resistant microphone-case: $5-15/unit, 10-year lifespan, 5,000-cycle latch, 25 kg/m³ foam. Over 5 years, our case is 4-5x cheaper per year of use. Total cost of ownership wins.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
Ordering Heat-resistant microphone-case is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (30 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
Every certificate we publish is dated and serialized. We do not stock certificates — we issue them per batch.
Established 2014. 13,000 sqm factory in Fusha Industrial Park, Shenzhen, Guangdong. 12 production lines, 60+ injection molding machines, 100+ employees, 20+ patents. Monthly capacity 80,000 units. Annual export revenue 8M+ USD to 47 countries.
