From Raw Material to
Final Shipment, Traceable.
A rigorous, end-to-end traceability system that documents every batch, every machine, every operator -- ensuring every YMS silicone product can be verified, audited, and trusted.
Step 01 -- Raw Material
Every Silicone Batch Carries Its Own Identity
We assign a unique batch code to every incoming shipment of silicone raw material. All records are archived with incoming inspection reports, supplier certificates, and compliance documentation.
-
1Supplier & Lot Number Supplier name, material grade, lot number, arrival date.
-
2Certification Verification FDA, LFGB, RoHS, REACH certificates archived per lot.
-
3Incoming Inspection (IQC) Hardness, viscosity, color, odor and purity test records.
Step 02 -- Production Order
One Order, One Identifier, One Complete Record
Each production order is tied to a unique Work Order Number (WO#) that links customer specifications, materials used, machines, molds, and output quantity into one unified record.
Customer Spec Sheet
Original drawings, tolerances, and signed approvals linked to WO#.
Material Linkage
All raw material batch codes consumed by this order are logged.
Production Timeline
Start date, end date, and each shift's output recorded.
Output Quantity
Yield, defect rate and finished count tracked per WO.
Step 03 -- Machine & Mold
Precise Records for Every Machine and Mold
We operate 32 solid silicone + 32 liquid silicone production machines. Each has a dedicated maintenance history and output log.

Step 04 -- People & Time
Who, When, and How -- Documented for Every Shift
Every production shift is signed off by a trained operator and a QC inspector with at least 5 years of experience. Time stamps and operator IDs are logged with each batch.
Step 05 -- Inspection
Multi-Stage Inspection, Fully Documented
From incoming material to pre-shipment, inspection records are archived with photos, measurements, and SOP compliance checks.
IQC -- Incoming
Material hardness, color, odor, and certificate verification before entering production.
IPQC -- In-Process
Dimensional checks every 2 hours, cycle parameter audits, visual flash inspection.
FQC -- Final
100% visual + functional inspection: tensile, tear, adhesion, and dimensional verification.
OQC -- Outgoing
Pre-shipment AQL sampling, packaging verification, and documentation audit.
Step 06 -- Non-Conformance
Issues Logged, Actions Tracked, Lessons Learned
Every quality anomaly triggers a Non-Conformance Report (NCR) with root cause analysis, corrective action, and verification -- all retained in the traceability chain.
Issue Detection
Any defect found during IPQC/FQC triggers automatic batch isolation and NCR issuance within 1 hour.
Root Cause Analysis
5-Why / fishbone analysis performed by QC Engineer. Linked to WO#, machine, operator, material batch.
Rework / Scrap Decision
Rework route, scrap quantity, re-inspection results, and sign-offs captured in a dedicated Rework Log.
Preventive Action
SOP update, operator retraining, mold maintenance -- closed-loop verification over 3 subsequent runs.
Step 07 -- Packaging
Packaging That's as Traceable as the Product Inside
Packaging materials -- cartons, inner boxes, labels, inserts -- each have their own batch code. We record the exact pairing of product batch to packaging batch.
Step 08 -- Shipment
From Loading Dock to Destination Port
Each shipment is tied to a packing list that references WO#, batch code, carton serial numbers, and shipping documents.
| Field | Example |
|---|---|
| Shipment ID | SHP-20240612-US |
| Linked WO# | WO-24-A007 |
| Carton Range | #001-#420 |
| Container No. | MSKU-7724810 |
| Documents | INV / PL / BL / COA |
Reverse Traceability
From a Single Complaint, Back to the Root Cause
If a quality issue surfaces in the market, we can trace back the entire history of that unit within hours -- from carton number to the original raw material supplier.
Record Management
Long-Term Archive, Audit-Ready at Any Time
All production, inspection, and shipment records are archived both digitally and in physical form for a minimum of 5 years.
Digital Archive
All records stored in a secure, searchable database. Indexed by WO#, batch code, SKU, and customer.
Physical Documents
Signed inspection sheets, test reports, and QC logs retained in climate-controlled storage rooms.
Audit Access
Open for client audits, 3rd-party certification bodies (ISO, SGS, BV) and brand compliance reviews.
