CNC Machining & Injection Molding — DFM/Moldflow Support, CMM Inspection, Prototype to Production Solutions.
For custom-manufactured parts, packaging is part of risk control. We design packaging solutions based on part geometry, surface finish, and shipping conditions to prevent damage, corrosion, and customs issues.
Packaging is not a final step — it directly affects part quality, delivery success, and total project risk, especially for overseas shipments.
Once parts leave the factory, they face humidity, vibration, stacking loads, and customs inspections. For precision and cosmetic components, the right packaging is as important as machining and inspection.
Our packaging approach starts before shipment day, so protection is designed into the project—not added at the last minute.
We select packaging based on part characteristics and shipping conditions — not a one-size-fits-all approach.
| Packaging Method | Best For | Typical Use Case |
|---|---|---|
| VCI anti-rust packaging | Steel & machined parts | Sea freight, long transit |
| Foam & cushioning | Precision & finished surfaces | CNC parts, anodized parts |
| Wooden crates (ISPM-15) | Heavy or large parts | Sea & rail shipping |
| Custom packaging | High-value or fragile parts | Multi-stage logistics |
Each method can be combined to match project-specific risks and the selected shipping route.
Packaging requirements vary significantly depending on how and how long parts travel. We align packaging design with the selected shipping method and expected transit time.
Typical transit: 20–40 days
Typical transit: 5–10 days
Typical transit: 2–5 days
Through experience with international manufacturing and delivery, we focus on preventing the most common failure points before parts leave the factory.
Packaging decisions are reviewed with the same attention as manufacturing and inspection.
Packaging can be defined up front or engineered together with you, depending on project requirements and internal standards.
Packaging can be:
If packaging is not specified, we propose a solution aligned with shipping conditions and confirm it before dispatch. This avoids assumptions and last-minute changes.
Packaging is planned as part of the delivery workflow — not added at the end.
Our coordination includes:
Visual workflow: from inspection to delivery
Each shipment follows a defined packaging workflow so that inspection, documentation, and export packaging are aligned with your shipping method.
Each shipment follows a defined packaging workflow so that risks are identified, controlled, and documented before your parts leave our factory.
If you want to reduce delivery risk and avoid surprises, review packaging and shipping together before your parts leave the factory.
