QUALITY CONTROL · CONTROLLED PRODUCTION

Quality Is Not a Final Check. It Is Built Into Every Step.

From incoming materials and gel formulation to filling, sealing, leakage testing, thermal performance, packaging and final release, Cryozin applies project-specific controls throughout production.

QUALITY SYSTEM

Define the Standard First. Reproduce the Approved Result Consistently.

Every material, structure, formula and market has different quality priorities. At project start, the approved sample and product specification are translated into production checkpoints, inspection criteria and release requirements.

PROCESS CONTROL

Eight Control Points Across the Production Process

Controls are matched to the approved specification, product structure and agreed inspection plan—not applied as a generic checklist.

01 · INCOMING

Incoming Material Inspection

Verify outer film, gel ingredients, fabrics, accessories and packaging against the approved specification.

02 · FORMULA

Formula & Batch Verification

Check formula batch, color, condition and the factors that influence hot and cold performance.

03 · FILLING

Filling Weight Control

Use first-piece approval and in-process checks to control fill weight, thickness and consistency.

04 · SEALING

Seal Parameter Control

Monitor high-frequency sealing and inspect seam integrity, position, width and surface appearance.

05 · LEAKAGE

Leakage Inspection

Check sealing performance using the agreed pressure or holding method for the product structure.

06 · PERFORMANCE

Thermal Performance Testing

Verify low-temperature flexibility, hot/cold performance and project-specific functional requirements.

07 · PACKAGING

Packaging Inspection

Confirm labels, instructions, barcodes, quantities, pack-out configuration and carton details.

08 · RELEASE

Final Inspection & Release

Complete inspection records and release the batch against the approved project requirements.

PRODUCT TESTING

Validate the Performance That Matters in Real Use

Testing is selected according to material, filling system, use temperature, construction and target market.

Seal & Leakage

Seal appearance, strength and pressure or holding leakage checks.

Low-Temperature Performance

Frozen flexibility, post-freeze appearance and cold-duration evaluation.

Heating Cycle

Appearance, temperature behavior and repeated heating-cycle checks.

Weight & Dimensions

Filling weight, critical dimensions, thickness and flatness checks.

Durability

Drop, pressure, strap, seam and repeated-use evaluation as applicable.

Print & Packaging

Print position, labels, barcodes, instructions and carton configuration.

QUALITY CONTROL FAQ

Questions From Procurement and Product Teams

Controls can include incoming material checks, seal parameter verification, seam appearance and dimensions, seal-strength testing, and pressure or holding leakage inspection. The exact method is matched to the product structure.
Incoming, first-piece, in-process and final inspection plans are defined for the project. Frequency and sampling follow the approved specification and agreed quality plan.
Yes. Submit your company standard, test method or inspection checklist during project review. We will evaluate feasibility and confirm execution before production.
Support may include ISO 13485, ISO 9001, CE, FDA-related documentation, RoHS, REACH, MSDS and product test records, depending on the product and destination market.
The approved sample, specification, key materials and production parameters form the repeat-production reference. Batch records and process inspection are used to monitor consistency.
