Industry Applications
Three real B2B use cases where KeXinMaterials Engineering Plastic Case is specified by procurement, operations, or engineering teams.
Industrial Automation & Robotics
System integrators and robot OEMs transport controller cabinets, sensors, and pneumatic components in our engineering-plastic cases. Chemical-resistant PP handles exposure to lubricants and coolants in factory environments.
Field Service & Maintenance
Industrial maintenance crews transport diagnostic tools, spare parts, and calibration equipment. Custom foam keeps small components organised; IP67 protects against shop-floor moisture.
Energy & Utilities
Wind and solar technicians carry torque tools, multimeters, and replacement parts in our cases. Stackable design saves space in service-vehicle cargo bays; OEM colour options support fleet branding.

FAQs
What is the MOQ for Engineering Plastic Case?
Standard SKUs 50-100 pcs, custom 300 pcs. Larger quantities get better pricing.
Can Engineering Plastic Case be customized with logo?
Yes. Silk-screen, hot stamping, laser engraving, UV spray - 4 options, MOQ 100pcs.
What certifications for Engineering Plastic Case?
CE / RoHS / ISO9001 standard. UN38.3, FDA, UL, MIL-SPEC optional.
How long for export delivery?
Production 30-45 days, sea 25-40 days to destination port (EXW/FOB), air 5-7 days, express 3-5 days. Buyer arranges own freight forwarder or via nominated forwarder.
What are the trade terms?
FOB Shenzhen / EXW Shenzhen, T/T 30% deposit, 70% balance before shipment.
How do I choose between standard SKU and custom OEM?
Start with our standard SKU (50-piece MOQ, 7-15 day delivery) to evaluate quality. If your project requires brand color, custom foam, or retail packaging, switch to OEM (100-piece MOQ, 30-45 day delivery, USD 200-1500 sample fee refundable against order ≥ 1,000 pcs). Standard SKU is 5-15% cheaper than equivalent OEM due to no setup costs.
Can you ship a sample before bulk order?
Yes. 1-3 free samples from stock SKUs (buyer pays shipping USD 30-80 via DHL/FedEx). Custom sample (logo, color, foam) costs USD 200-1500 including mold setup, refundable against orders ≥ 1,000 pieces. Sample lead time 7-10 days. Sample evaluation is highly recommended for OEM.
What is the difference between IP67 and IP68?
IP67 = protected against temporary immersion (30 minutes at 1 meter depth). IP68 = protected against continuous immersion (typically 1-3 meters for 30+ minutes; depth specified by manufacturer). For most B2B applications (transport, storage, outdoor use), IP67 is sufficient. IP68 is needed for underwater deployment (e.g., marine research, ROV operations). IP68 SKUs cost 10-25% more than IP67 equivalents.
What certifications do your cases have?
ISO9001:2015 (quality management), ROHS (EU hazardous substance), CE (EU conformity), REACH (EU chemicals), IP67/IP68 (ingress), MIL-STD-810G (vibration / drop / temperature), ATA 300 Category I (luggage), California Prop 65, FDA compatibility statement (medical SKUs), NSN registration support (defense SKUs). Full certification list per SKU available on request.
How long does delivery take from order to my warehouse?
Standard SKU in stock: 7-15 days production + 18-35 days ocean freight (depending on destination: 18-26 days to US West Coast, 24-32 days to EU, 28-35 days to US East Coast). Custom OEM: 30-45 days production + ocean freight as above. Air freight 3-7 days available at higher cost. Total transit time FOB Shenzhen/FOB Ningbo to your warehouse is typically 4-8 weeks door-to-door (excluding customs clearance).
