Precision Silicone
Tooling & Sampling
From concept to validated sample -- our in-house tooling workshop delivers precision molds and golden samples that bridge design intent and mass production reality. 15 years of expertise, ±0.1mm tolerance guaranteed.
Mold Design, Manufacturing
& Trial Molding
Three sequential pillars form the foundation of every project -- each stage validated by senior engineers before advancing to the next.
Mold Design
DFM analysis, flow simulation, cavity layout optimization using UG, Pro/E, SolidWorks and Moldflow.
Mold Manufacturing
Precision CNC machining, EDM, wire-cutting, and mirror polishing with imported steel (S136, NAK80, 718H).
Trial Molding (T0-T2)
Iterative first-shot testing, parameter tuning, and defect analysis until all dimensional and visual specs pass.
Rapid Prototype
& Production Sample
Two parallel sampling tracks -- one for fast validation of design intent, another for market-ready quality confirmation.
Rapid Prototype Sample
3-7 daysHand-cut silicone samples, 3D-printed references, or soft tooling prototypes -- ideal for early concept validation, ergonomic review, and marketing visuals before mold investment.
- SLA / Silicone casting
- Appearance / fit check
- Low cost iteration
- Multi-color options
Production Tooling Sample
10-15 daysFirst article from the actual production mold -- identical to mass production in material, process, and finish. The golden sample for approval and reference throughout the entire production run.
- Production-grade tooling
- Full dimensional report
- FDA / LFGB validation
- Pantone color matching
Modification, Maintenance
& IP Protection
Your tooling investment is protected throughout its service life. We maintain detailed mold logs, perform scheduled upkeep, and respect full customer ownership of tooling and intellectual property.
Mold Modification
Engineering change requests handled within 3-5 days, including cavity updates, logo revisions, and dimensional adjustments.
Preventive Maintenance
Scheduled cleaning, polishing, and component replacement every 50,000 cycles to ensure consistent part quality.
IP Protection & NDA
Mutual NDA signed before any file exchange. Designs are kept exclusive to your account with controlled access.
Mold Ownership
Full tooling ownership transferred to customer upon final payment. Transfer or relocation supported anytime.
Every mold is archived with a unique ID -- storage conditions, usage history, and maintenance records are logged for the full lifecycle, ensuring full traceability.
Sample Inspection, Review
& Sign-off Process
A disciplined four-step gate -- no sample leaves our factory without passing dimensional, functional, and visual verification.
Dimensional Inspection
CMM measurement against 2D drawings. Full dimensional report with ±0.1mm tolerance verification.
Functional Testing
Tensile, tear resistance, temperature cycling, and durability tests per application scenario.
Internal Review
Cross-functional review with QC, engineering, and production. Issue log compiled.
Customer Sign-off
Sample shipment + full report. Signed golden sample becomes production reference.
Full Reports
Dimensional, material, and testing reports in English -- ready for your QA archives.
Visual Documentation
Photo and video evidence of critical features before shipment.
Golden Sample Retention
Approved samples retained at factory as reference throughout production.
Pilot Run to
Mass Production
After sample approval, we validate the production system at scale -- a pilot run of 500-2,000 pieces confirms stability, cycle time, and yield before full ramp-up on our 64 injection lines.
Pilot Run Validation
Small-batch trial run (500-2,000 pcs) to verify consistency, cycle time, and defect rate.
Production SOP Freeze
Final process parameters locked. SOP documented for every workstation.
Mass Production Ramp-up
Full-scale production with inline QC and AQL 1.5/2.5 sampling inspection.
Typical Mold Projects
& Craft Techniques
A selection of mold complexities we handle every day -- single-cavity to 32-cavity, overmolding, insert molding, and multi-material co-injection.
