Quality, Verified at
Every Production Step
From the first injection to the final batch, our In-Process Quality Control (IPQC) system monitors parameters, dimensions, and appearance in real time -- ensuring stability across every production run.
Step 01 -- Setup
Pre-Production Parameter Confirmation
Before a single shot is produced, every machine, mold, and material setting is cross-verified against the master production file. This eliminates variability before it enters the line.
-
1
Material Lot Verification Silicone batch certificate, color masterbatch ratio, and RoHS/REACH compliance confirmed.
-
2
Mold & Tooling Check Cavity count, cleanliness, cooling channels, and parting line integrity validated.
-
3
Machine Parameter Lock Temperature, pressure, curing time, and clamping force recorded in SOP.
Step 02 -- Validation
First Article Inspection (FAI)
A full-dimensional and functional verification on the first qualified sample from every mold cavity -- mass production begins only after sign-off.
Dimensional Report
Full measurement of critical dimensions against 2D drawing, including CMM scans.
Material Hardness
Shore A durometer test, ensuring consistency with approved sample tolerance.
Functional Test
Fit, seal, foldability, and assembly tests specific to each pet product category.
Approval Sign-off
QC manager, engineer, and production head jointly approve before full run.
Step 03 -- Precision
Critical Dimension Control
Every product has a set of critical-to-function dimensions. Our in-process operators measure these at defined intervals using calibrated instruments, with tolerance held tight at ±0.1 mm.
Step 04 -- Aesthetics
Appearance Quality Control
Visual integrity defines premium perception. Each product is inspected against a controlled golden sample under standardized lighting conditions.
Surface Defects
Checks for flash, flow marks, air bubbles, white spots, and foreign contamination.
Color Consistency
Pantone matching with chromameter verification against approved color card.
Print & Logo Check
Silk screen, pad printing, and UV coating verified for position, clarity, and adhesion.
Texture & Finish
Matte, glossy, or soft-touch textures compared under D65 standard lighting.
Trimming & Edges
Burrs removed, parting lines smoothed, no sharp edges on pet-contact surfaces.
Golden Sample Reference
A customer-approved golden sample is kept on each line as the real-time visual benchmark throughout production.
Step 05 -- Monitoring
Real-Time Production Parameter Monitoring
Our 64 production lines (32 solid + 32 liquid silicone) continuously record vulcanization parameters. Deviations trigger immediate operator alerts, preventing defective shots from accumulating.
Step 06 -- Patrol
Patrol Inspection Frequency & Records
QC inspectors -- each with 5+ years experience -- perform scheduled patrols with digital record-keeping for full traceability.
| Checkpoint | Frequency | Sample Size |
|---|---|---|
| Dimensional Check | Every 2 hours | 5 pcs / cavity |
| Appearance Inspection | Every 1 hour | 10 pcs / shift |
| Parameter Verification | Every 4 hours | Full line scan |
| Hardness Testing | Every batch | 3 pcs / batch |
| Functional Test | Shift start/end | 5 pcs / check |
Step 07 -- Containment
Non-Conforming Product Isolation
When defects are detected, products are immediately red-tagged and moved to a physically separated quarantine area. This prevents mixing with qualified stock and triggers a formal review process.
Step 08 -- Correction
Problem Correction Mechanism
Our 8D-based corrective action system ensures every quality issue -- whether minor or systemic -- is traced to its root cause and permanently resolved.
Detect & Contain
Immediate line stop, isolate affected lot, prevent further defect flow.
Root Cause Analysis
Fishbone diagram, 5-Why, and parameter review by cross-functional team.
Implement Fix
Adjust parameters, refurbish mold, retrain operator, or update SOP.
Verify & Document
Monitor next 100 cycles, close CAPA report, share lesson across lines.
Step 09 -- Traceability
Production Batch Management
Every production batch carries a unique code linking it to raw material lot, machine, operator, inspector, and shift. This end-to-end traceability enables rapid response to any downstream quality query.
Case Study
In-Process Quality in Action
A real production case showing how IPQC prevented a potential large-scale defect for a European pet brand.
Micro flow-mark detected within 90 minutes -- zero defect units shipped.
Hourly patrol inspector found subtle flow marks on 2 of 10 sampled bowls at hour 3.
Mold vent slightly blocked after a material changeover, causing uneven flow at corner radius.
Line paused for 25 minutes, vent cleaned, SOP updated. Only 180 pcs quarantined; shipped batch achieved 100% customer AQL pass.
