When customers place a large order with us, they are trusting Minfeng with more than just paper — they are trusting us with their timelines, their brand consistency, and the expectations of their own customers. We take that responsibility seriously. That is why our approach to quality control is not built on slogans, but on habits we’ve kept for years and systems we refine continuously.

Below are the practices we genuinely adhere to in our actual production.

1. Rigorous Raw-material Control

Paper quality is often decided long before it reaches the machine. At Minfeng, we work with a group of long-term pulp suppliers whom we’ve cooperated with for many years. We know their material, they know our standards, and this mutual understanding keeps surprises to a minimum.

Every batch of raw material must pass an incoming inspection — no exceptions. Moisture, appearance, fiber condition, impurities… If any single criterion fails, we won't let it proceed to the next step.

What truly helps us maintain consistency is our automated pulp mixing system. Formulations rely not on “experience-based intuition,” but are entirely executed by the system with locked ratios. Thus, whether producing 100 tons, 500 tons, or 1,000 tons, pulp consistency remains unwavering.

2. Automated Paper Production Lines

When many customers visit, their first question is always: “How come your paper machines run so smoothly?”

It's not that the machines themselves are inherently stable—it's because we've worked to eliminate as many variables as possible.

Minfeng currently operates 7 automated production lines, each equipped with DCS, QCS, and ISA control systems.

These systems continuously monitor data like speed, tension, moisture content, and thickness. Should any machine deviate slightly from specifications, it automatically corrects itself—eliminating the need for constant manual oversight.

For customers, this means:

Whether you order 5 tons or 50 tons, batch-to-batch variations are minimized to the greatest extent possible.

3. In-line Monitoring at Every Stage

In the manufacturing process, problems never “appear suddenly.” They all build up gradually.

Therefore, we prefer to intercept issues mid-production rather than discover nonconformities at the final stage.

At every stage, we employ real-time monitoring:

• GSM
• Thickness
• Surface uniformity
• Moisture content
• Defect detection (black spots, holes, streaks)

If data from any point “looks off,” the system alerts operators for immediate intervention.

This is why we achieve minimal roll-to-roll variation in large orders—errors are eliminated the moment they appear.

4. Advanced Laboratory Resting (CNAS Standard)

Our laboratory is not merely for show, nor is it just for “appearances.”

Its purpose is to ensure every piece of data is verifiable and traceable.

We've configured our testing environment and equipment to CNAS standards, enabling comprehensive testing for strength, burst resistance, Cobb angle, whiteness, friction, thickness, and more.

Many clients ask: “Do you perform these tests on every batch?”

The answer is: Yes. Every batch is documented, and samples are retained.

What you see isn't “we believe it's compliant”—it's clear data proving its compliance.

5. Strict QC and Traceability

The final hurdle is our own QC team.

They're generally not easy to please, as they don't give production departments any special treatment—they only look at data and samples.

QC ensures:

• No visual defects on each roll
• Thickness and roll diameter within specifications
• Undamaged packaging
• Complete production records
• Sample retention matching test reports

Upon order completion, we archive all data alongside physical samples. Should any questions arise later, we can trace back directly to the raw materials, equipment, time, and even the operator involved.

Transparency builds the most direct trust.

What this Brings to You

The sole purpose of all these processes is to ensure customers never have to worry that the next batch will be “too different from the last one.”

For Minfeng, quality isn't just a slogan plastered on walls—it's embedded in our daily operations. Consistent raw materials, automated production, real-time monitoring, lab validation, and rigorous QC aren't just buzzwords; they're our established practices and way of doing business.
