Choosing 聚丙烯改性塑料箱 manufacturing process for the first time is harder than it looks. We have seen buyers overspend 2x by over-specifying size, and underspend by skipping certifications. This page is the decision framework.
Below is the catalog data for 聚丙烯改性塑料箱 manufacturing process. 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 |
|---|---|---|---|---|---|
| WL1204 | 120×90×40 mm | 115×78×32 mm | 100 g | PP | Component Storage |
| WL2005 | 195×170×46 mm | 190×135×40 mm | 175 g | ABS | Tool Kit |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PA66+GF30 | Automotive Tooling |
The most common model for "聚丙烯改性塑料箱 manufacturing process" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Shell material for 聚丙烯改性塑料箱 manufacturing process is selected per use case: standard PP for general purpose, PP+GF for heavy-duty (10% glass fiber improves impact strength by 35%). Foam is 25 kg/m³ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 Ω) available for electronics.
The shell is rated IP65 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -30 ~ +90 °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.
In 2024, we shipped 聚丙烯改性塑料箱 manufacturing process for: (1) Film production — ARRI Alexa Mini + accessories in custom foam. (2) Drone operators — DJI Mavic 3 + RC + 6 batteries. (3) Broadcast — RED Komodo + 2 lenses + monitor. (4) Military — rifles + scopes + ammo. (5) Medical — first aid kits + AED.
For 聚丙烯改性塑料箱 manufacturing process, the decision comes down to: equipment dimensions (always measure with 5-10mm foam clearance), IP rating (IP65 indoor, IP67 outdoor, IP68 water), and certification (FCC for USA, CE for EU, MIL-STD for military). Beyond that, it is foam layout and quantity discount.
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.
After 聚丙烯改性塑料箱 manufacturing process ships: (1) We send QC photos before shipment. (2) Lot certificate with serial numbers. (3) 90-day defect replacement. (4) Foam re-cut service for equipment changes. (5) 5-year case body warranty. (6) Tooling stored 3 years for easy reorder.
We have 150+ custom design cases since 2014. Whatever your question is, we have probably seen it before.
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.
Direct from the OEM. Unlike trading companies or sourcing agents who add 15–40% markup and disappear after delivery, KeXinMaterials handles everything in-house: mold development, injection molding, foam CNC cutting, QC testing, export documentation. Our 2024 buyer survey showed 87% repeat-order rate and 0.3% defect rate across 47 countries.

📹 60-second factory + product walkthrough. 聚丙烯改性塑料箱 manufacturing process buyer guide walkthrough, equipment fitting, quote process
OEM: you design, we manufacture. ODM: we design (based on your use case), you brand. OEM requires 3D model / spec sheet from you. ODM requires usage description only. OEM MOQ 500, ODM MOQ 200. Both lead time 25-30 days for tooling.
Yes. Free samples for standard WL series (you pay shipping, $30-80 via DHL). 5-day sample lead time. Custom samples: $200-500 fee (refundable on order >2,000 units), 7-15 day lead time.
No, you can supply your own foam. We can ship the case without foam (15% cost reduction) or with custom foam (your spec). Our standard foam is 25mm base + 10mm convoluted lid, CNC-cut to 0.5mm tolerance.
PP case body: 10+ year typical service life with normal use. Foam set: 5+ years before showing compression set. Latch: 5,000-10,000 open/close cycles. Hinge: 10,000 cycles. Replace foam when it no longer rebounds; replace case when latch or hinge fails.
We can re-cut foam for the same case. Cost: $20-50 per foam set depending on size. Lead time: 5-7 days. We keep your foam layout in our database for 3 years for easy re-order. If equipment changes significantly, you may need a different WL series.
