From First Sketch to
Approved Sample
A transparent, structured sampling program designed for international brands and importers. Every sample reflects the exact standards you'll receive in mass production -- material, finish, tolerance, and compliance included.
Three Sample Types,
One Quality Standard
Depending on your product stage and purpose, we offer stock samples, custom samples, and tooling samples -- each produced with the same food-grade silicone and strict QC protocols.
Stock Samples
Lead Time: 1-3 Days
Ready-made standard products from our catalog -- ideal for quality evaluation, material testing, and market feasibility checks.
- Immediate dispatch
- Low or free sample fee
- Original factory specs
Custom Samples
Lead Time: 7-10 Days
Based on your existing molds or minor modifications -- new colors, prints, logos, or secondary processing on standard shapes.
- Logo & color matching
- Silkscreen, UV, pad print
- Custom packaging mock-up
Tooling Samples
Lead Time: 25-35 Days
Full OEM/ODM development -- new mold design, prototyping, DFM review, and first-shot sample from your dedicated tooling.
- DFM & engineering review
- ±0.1mm tolerance
- Mold ownership options
Prepare These
4 Essentials
The more detailed your brief, the faster and more accurate your sample. Our engineering team reviews every submission before quoting.
No drawings? No problem -- send a reference image or physical sample and our design team will help you build the specs.
Technical Drawings
2D/3D files (STEP, IGS, PDF, DWG) with dimensions, tolerances, and material specs.
Color Specification
Pantone code (TPG/TCX) or a physical color swatch for accurate color matching.
Logo & Artwork
Vector files (AI, EPS, PDF) with placement, size, print method (silkscreen, pad, UV, debossing).
Packaging Brief
Box style, dieline, barcode, inserts, hangtag -- plus required certifications (FDA, LFGB, CPSIA).
Transparent Pricing,
No Hidden Costs
Sample fees cover material, labor, and tooling adjustments. All fees are refundable or deductible against your bulk order (subject to MOQ confirmation).
Stock Samples
Courier charges paid by client (DHL/FedEx/UPS account preferred).
Custom Samples
Depending on complexity, color, logo method, and quantity requested.
Tooling Samples
Includes mold development. Final cost based on cavity count & part complexity.
Four Steps From
Brief to Doorstep
Sample Production
Engineering review, material prep, mold adjustment, and injection molding under full ISO 9001 protocol.
Quality Inspection
Full dimensional check, appearance, functional test, and tear/tensile verification by our QC team.
Shipping & Tracking
Dispatched via DHL, FedEx, or UPS with full tracking details and inspection photos sent in advance.
Client Feedback
We request a written confirmation or revision notes within 7 days for seamless transition to mass production.
Factors That Shape
Your Timeline
Mold Complexity
Multi-cavity, undercuts, and co-molded parts require longer tooling.
Color & Material
Custom Pantone matching or special additives (glow, antibacterial) require extra batching time.
Secondary Processing
Silkscreen, UV coating, adhesive backing, or spray oil adds 2-5 working days.
Packaging & Certification
Printed boxes, hangtags, and third-party lab testing (FDA/LFGB) require coordination time.

Refined Until
You Approve
We offer structured sample revision cycles with clear documentation. Once approved, your signed Golden Sample becomes the quality benchmark for mass production.
First Revision -- Free
Minor adjustments to color, logo size, or surface finish are included at no extra cost.
Second Revision -- Partial Charge
Dimensional or mold-structure changes may incur additional tooling cost (quoted upfront).
Final Confirmation
Signed & sealed Golden Sample retained by both parties as the production reference standard.
The reference for every single unit in your bulk order.
