QUALITY CONTROL

Quality Built Into
Every Product Stage

Yuanze connects development review, incoming material and packaging checks, in-process quality control and finished-product review through one controlled quality path.

THE QUALITY PATH

Four stages of review.
One connected control system.

Quality starts during development and continues through incoming review, production activity and the finished-product stage.

Development review

FORMULA / DEVELOPMENT REVIEW

Align the formula direction, sample observations and applicable product requirements before the project moves forward.

  • Formula direction
  • Sample review
  • Project requirements

Incoming review

INCOMING MATERIAL & PACKAGING REVIEW

Review received materials and packaging against the applicable appearance, dimension and specification information.

  • Material receipt
  • Appearance review
  • Specification match

Production control

IN-PROCESS QUALITY CONTROL

Carry documented checks into production through first-piece review, filling observation, coding confirmation and production sampling.

  • First-piece review
  • Filling checks
  • Coding and label review

Finished review

FINAL PRODUCT REVIEW

Review the finished product, presentation and required project criteria before the controlled release stage.

  • Finished product
  • Packaging presentation
  • Release readiness

LABORATORY & TESTING

Testing organized around
customer decisions.

Twenty-two in-house testing items are organized into four practical quality-review groups.

CURRENT IN-HOUSE QUALITY DIRECTION

PHYSICAL / CHEMICAL REVIEW

Current in-house review includes applicable pH, viscosity, conductivity, density, centrifuge and heat or cold resistance checks.

Testing scope is defined according to the product and project requirements.

CURRENT IN-HOUSE QUALITY DIRECTION

MICROBIOLOGICAL REVIEW

Current in-house work includes total plate count, mold and yeast review, together with applicable environmental monitoring.

Monitoring may cover air, hands, equipment, water, production items and filling-area surfaces.

CURRENT IN-HOUSE QUALITY DIRECTION

STABILITY / COMPATIBILITY

Development review connects the formula, sample behavior and packaging direction before production preparation.

The review plan is defined by the product direction and project requirements.

CURRENT IN-HOUSE QUALITY DIRECTION

PACKAGING / PRODUCT REVIEW

Product presentation is reviewed together with component appearance, dimensions and specification information where applicable.

Packaging review helps align component presentation and project readiness.

QUALITY IN ACTION

Process evidence,
not equipment display.

People, actions and review points make the quality system understandable without turning the page into an instrument catalog.

CONNECTED RESPONSIBILITY

Quality does not begin
or end in the laboratory.

It shapes development decisions and continues inside the manufacturing workflow.

QUALITY × PRODUCT DEVELOPMENT

Quality is part of development.

Formula review, sample feedback and applicable stability or compatibility work connect the brief with a production-ready direction.

SEE THE PRODUCT DEVELOPMENT PROCESS
QUALITY × MANUFACTURING

Quality continues during production.

Incoming review, in-process checks and finished-product review remain connected to the manufacturing sequence.
