Shore A Hardness
Hardness verified from 20A to 80A against your specification, per batch.
Silicone Quality Inspection & Traceability
Three-stage quality control — IQC, IPQC and OQC — backed by calibrated measuring equipment and full batch traceability, so every part ships exactly to specification.
Three-Stage Quality
Incoming, In-Process, Outgoing
Quality is not a final check — it runs through the entire process. Incoming material is verified before use, dimensions are monitored during molding, and every finished batch is inspected before shipping.
- IQC — Incoming — raw silicone compound and material certification
- IPQC — In-process — dimensional SPC during molding and post-cure
- OQC — Outgoing — final inspection, packaging and release
- Batch traceability — material, mold, machine and operator linked
Inspection Equipment
Calibrated Measurement, Real Results
Photographs from our quality lab — the equipment that verifies hardness, tensile strength, dimensions and visual quality on every batch.
Tensile & Elongation
Tensile strength, elongation and tear resistance tested to confirm mechanical performance.
Optical & AOI Inspection
Vision and optical systems measure fine features that calipers cannot reach, and automated optical inspection (AOI) screens surface defects at production speed.
Incoming Material IQC
Raw silicone compound checked and certified before it enters production.
Inspection Records
Every batch is documented with dimensional and visual inspection records.
Precision Probing
Point-to-point probing verifies critical dimensions on molded components.
Test Methods
What We Measure, How
Each test method is selected to match your part and market, and the applicable report is supplied with your shipment.
| Test | Method / Scope |
|---|---|
| Hardness | Shore A durometer, 20A–80A |
| Dimensions | Calipers, optical/vision, SPC on critical dimensions |
| Surface & visual | Automated optical inspection (AOI) for defects, flash and contamination |
| Tensile & elongation | Universal tensile tester |
| Color | Pantone match, ΔE ≤ 1.5 |
| Food contact | FDA 21 CFR / LFGB migration testing (where required) |
| Restricted substances | RoHS / REACH screening |
| Traceability | Lot linkage: material → mold → machine → operator |
Process Control
SPC & Batch Traceability
Critical dimensions are tracked with statistical process control during molding, and every batch is linked back to its raw material, mold, machine and operator — so if a question ever arises, we can trace it to the source.
Verified Process Capability
A Real Cpk, From a Real Production Run
Process capability is only meaningful when it comes from an actual measured production run. Below is a real SPC study for a medical LSR component — not a headline number, but the result of a documented run.
Medical LSR Seal Gasket
Characteristic: inner diameter ⌀ 8.00 mm ± 0.02 mm (USL 8.02 mm / LSL 7.98 mm), tracked with X-bar / R control charts.
Cpk 1.24
Pp 1.27 · Ppk 1.19. This measured Cpk reflects the process as it runs today; we monitor it run over run and report the trend, rather than citing a single best case.
Documented & On Request
The full capability study — control charts, raw measurements and the Cpk calculation — is available on request under NDA for qualified projects.
Note on interpretation: a Cpk of 1.33 is a common general reference, not a universal requirement. The acceptance threshold for any given characteristic is set by your product's specification and the customer's agreed limits — we confirm the applicable Cpk target per part and report the measured result against it, so a figure is never shown out of context.
