01
Design review
We start from your product photo, sketch, or physical sample. The factory reviews product size, cavity depth, clarity, shelf presentation, stacking, and destination market before tooling is discussed.
Capabilities
Factory capabilities, from design review to export
HongPack handles design review, existing mold checks, custom tooling, thermoforming production, sample approval, carton packing, and export preparation with direct factory communication.
15+Years in thermoforming
8Production lines
3-5Days for existing-mold samples
15-25Working days after sample approval
How projects move
A clear route for custom and existing-mold orders
Buyers do not need to start with a perfect technical drawing. Send practical information first, then we help turn it into a factory-ready brief.
02
Existing mold or custom tooling
We check our existing mold library first. Custom tooling is discussed only when product shape, cavity depth, fit, or display requirements cannot be met by a ready mold.
03
Thermoforming production
Eight production lines support PET, rPET, PP, PS, HIPS, and PVC forming for blister packs, food clamshells, agricultural trays, and industrial component trays.
04
Packing and export support
Carton method, nesting direction, quantity per carton, gross weight, labeling, and destination requirements are confirmed before mass production and export from Ningbo Port.
05
Documents and compliance route
RoHS, REACH, and food-contact documentation can be discussed according to material, application, and destination market. We only confirm documents that are available for the selected material.
Factory verification
What overseas buyers can confirm before ordering.
Factory credibility should be visible in the working process, not only in a slogan. We keep the production route, mold decision, sample stage, and export preparation clear.
- Factory location and production team in Ningbo, China
- Material direction reviewed against product use and destination
- Existing mold route checked before custom tooling
- Physical sample approval before mass production
- Carton packing and export details confirmed in advance
- Direct contact by email or WhatsApp throughout the project
Material quick reference
Choose material by use, forming depth, and destination market.
Material choice is reviewed at the inquiry stage. Exact thickness and documents depend on the product, application, and destination requirements.
