02 · Engineering
Structure, Material
& Core Functions
Every collapsible container is engineered as a system -- concertina folding geometry, food-grade silicone body, and reinforcement elements working in harmony.
Concertina Fold Geometry
Precision-engineered ring segments collapse flat and expand firmly, reducing storage volume by up to 75% without compromising rigidity when deployed.
100% Food-Grade Silicone
BPA-free, odorless, non-toxic. Compliant with FDA, LFGB, RoHS, REACH. Operating range -40°C to +230°C -- microwave, freezer, oven, and dishwasher safe.
Reinforced Plastic Frame
PP or Tritan rims co-molded with silicone body add structural rigidity, support snap-lock lids, and enable microwave-safe handling.
Airtight Sealing System
Four-latch snap closures with silicone gaskets deliver IPX4-grade leak resistance for liquids, soups, and sauces during transport.
03 · Customization
Design It
Exactly Your Way
Every parameter is yours to specify. From fold architecture to Pantone color matching -- our ODM team translates brand briefs into production-ready specifications.
Collapse Depth
Choose between 2-ring, 3-ring, or multi-stage concertina folds to match capacity and compact-storage goals.
Shore A Range
Specify silicone hardness from 40° to 70° Shore A -- softer for easier folding, firmer for structural stability.
Rim Options
Optional PP, Tritan, or ABS rims for added rigidity and lid compatibility. Co-molded or snap-fit assembly.
Closure Systems
Snap-lock latches, screw-top, press-fit, or vented microwave lids -- each with silicone gasket seals.
Pantone Custom
Full Pantone / RAL color matching with solid, translucent, gradient, or marbled finishes.
Logo & Finish
Silkscreen, debossing, embossing, UV printing, and laser engraving to make every unit uniquely yours.
04 · Workflow
Tooling, Prototyping
& Sample Approval
A structured 5-stage process ensures every detail is validated before mass production begins.
Design Review & DFM
Our engineers review your 2D/3D files, suggest manufacturability optimizations, and lock in critical specs.
Mold Development
Precision CNC mold fabrication with hardened steel. Multi-cavity tooling for scaled production efficiency.
T1 Prototype
First-trial samples delivered within 15 working days. Full dimensional, functional, and visual inspection reports included.
Iteration & Refinement
Mold adjustments, color matching, surface texturing -- iterate until every parameter matches your approval criteria.
Golden Sample Sign-Off
Confirmed master sample becomes the production benchmark -- sealed, documented, and referenced for every batch.
05 · Production
Scaled Manufacturing
& Assembly
64 injection machines across solid and liquid silicone lines, running 24/7 under ISO 9001 governance. From molding to retail-ready packaging -- all in-house.
32 solid + 32 liquid silicone production lines running concurrently.
Standard lead time from PO confirmation to shipment-ready inventory.
Scalable output for high-volume SKUs across multiple product families.
Multi-material co-molding, lid fitting, and final packaging under one roof.
Packaging & Fulfillment
Retail Packaging
Color boxes, blister cards, hangtags, kraft sleeves -- fully branded.
E-commerce Ready
Amazon FBA labeling, polybagging, barcode compliance.
Global Shipping
FOB, CIF, DDP terms. Air, sea, and express freight support.
06 · Quality Assurance
Tested for Lifetime
Fold Durability
Every design is validated through rigorous laboratory and field testing. We certify fold cycles, seal integrity, and structural stability -- because real-world performance is non-negotiable.
Fold Cycle Lifetime
Automated fatigue testing -- every container validated to withstand 10,000+ collapse-expand cycles with no material fatigue or seal failure.
Seal Integrity Test
Pressure-chamber and tilt-leak tests verify watertight performance. Every lid-gasket interface audited at the batch level.
