The most common model for "small-protective-case manufacturing process" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).

Temperature and Chemical Resistance of small-protective-case manufacturing process

small-protective-case manufacturing process shells are rated -40°C to +80°C per MIL-STD-810H Method 501.7 (high) and 502.7 (low). Chemically resistant to petroleum, mineral oil, dilute acids, alcohols, and most industrial solvents. Not resistant to concentrated sulfuric acid, aromatic, or chlorinated solvents.

The shell is rated IP68 (submersible 5m / 30 min) ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -30 ~ +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.

What Equipment Fits in small-protective-case manufacturing process

Common equipment we have designed small-protective-case manufacturing process foam layouts for, based on real customer projects since 2014: DSLR + 2-3 lenses, mirrorless kits, cinema cameras with matte box + monitor, drones (DJI Mavic/Phantom/Inspire) with 5 batteries, broadcast lighting kits, military optics, medical devices.

small-protective-case manufacturing process vs Alternatives: Honest Comparison

When evaluating small-protective-case manufacturing process options, focus on three metrics: (1) Foam density — cheap cases use 15 kg/m³ foam that bottoms out; ours is 25 kg/m³, 5+ year use. (2) Latch cycle rating — cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification — every batch ships with serialized IP test certificates.

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.

small-protective-case manufacturing process: 5-Step Order Process

Ordering small-protective-case manufacturing process is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (25 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.

Frequently Asked Questions

Can I customize the color of small-protective-case manufacturing process?

Yes, custom colors available for orders >500 units. Color match to Pantone / RAL: $300 color matching fee, 7-10 days. Standard colors (black, gray, olive, orange) ship with no extra cost and 25-30 day lead time.

What is the difference between injection molded and blow molded cases?

We use injection molding exclusively — denser walls, tighter tolerances, better IP rating. Blow molding produces hollow cases with thinner walls (1-2mm), cheaper, but not suitable for IP67 or MIL-STD-810H drop test. If a supplier offers 'injection' at 1/3 our price, it is likely blow-molded.

Do you ship to residential addresses?

Yes for DDP and CIF. For FOB or EXW, we ship to a commercial port or address with customs broker. Residential delivery in some regions (EU, USA) requires a local broker to handle customs clearance.

What does small-protective-case manufacturing process mean?

small-protective-case manufacturing process refers to a protective case designed for specific equipment, use case, and buyer profile. In B2B sourcing, it means a factory-direct product with documented specs, certifications, and lead time. KeXinMaterials has supplied small-protective-case manufacturing process to 47 countries since 2014.

How do I choose the right small-protective-case manufacturing process?

Step 1: Define your equipment's outer dimensions (L×W×H in mm). Step 2: Add 5-10mm clearance for foam thickness. Step 3: Match to WL series: WL1204 → WL2005 → WL2808 → WL3812 → WL5020. Step 4: Confirm IP rating (IP65 indoor, IP67/IP68 outdoor/water). Step 5: Send spec for 12h quote.
