Key Production Process Control Points for Flooring Manufacturing Factories

In spc flooring production or laminate flooring production, quality control and production management are critical. Here are the key areas flooring factories need to pay special attention to during manufacturing, along with corresponding management points:

I. Raw Material Control

Substrate Selection

Laminate flooring: Ensure HDF density ≥850kg/m³ and formaldehyde emissions meet standards (ENF/E1).

SPC flooring: Precise ratio of stone powder to PVC (typically 60-70% stone powder), avoiding impurity contamination.

Decorative and Wear Layers

Control color variation in decorative paper, ensure even aluminum oxide coating (≥30g/m²).

Adhesive Environmental Standards

Use formaldehyde-free (e.g., MDI) or low-formaldehyde adhesives with regular free formaldehyde testing.

VI. Common Issue Prevention

II. Key Production Process Controls

Pressing Process of laminate flooring

Precise temperature (180-220°C) and pressure (300-400 tons) control to prevent delamination or bubbling.

Cooling: Gradual cooling to avoid warping from internal stress.

Cutting Precision

Maintain dimensional tolerance within ±0.2mm; high-precision molds for locking systems (e.g., Unilin, Valinge).

Surface Treatment

SPC Flooring : Ensure complete UV curing (intensity ≥800mJ/cm²) for wear and scratch resistance.

Waterproof Treatment

Laminate flooring requires wax-sealed locks; SPC cores need waterproof testing (≤3% water absorption in 24h).

III. Quality Inspection

Physical Performance Testing

Wear resistance of laminate flooring : Taber testing (AC3 ≥2500 cycles, AC4 ≥4000 cycles).

Impact resistance of laminated flooring: Steel ball drop test (1kg ball from 1m height, no dents).

Environmental Testing

Batch sampling for formaldehyde, VOCs, heavy metals (compliant with EN 13329, CARB NAF).

Dimensional Stability

Simulate humidity/temperature changes (e.g., 80°C/95%RH for 48h), observe expansion rate (≤0.5% optimal).

IV. Packaging & Storage

Protective Packaging of laminate flooring vinyl flooring order

Edge guards + moisture-proof wrapping (packaged at ≤60% humidity).

Warehouse Management

Avoid direct sunlight; stack height ≤1.5m (prevent warping); FIFO principle.

V. Environmental & Safety

Emissions Control

Install VOCs treatment (e.g., activated carbon + RTO incineration) for pressing.

Dust Management

Cutting workshops require dust removal systems (PM2.5 ≤50μg/m³).

Wastewater Recycling

Recycle SPC flooring cooling water to prevent stone powder pollution.

VII. Continuous Improvement

Digital Management: Implement MES for real-time monitoring (temperature/pressure alerts).

R&D Investment: Develop antibacterial/soundproof floors (e.g., silver-ion coating).

Customer Feedback: Establish traceability systems (batch-to-order tracking).

Summary: The core of flooring production is "stability control." End-to-end standardization from materials to finished products, combined with eco-friendly and smart upgrades, ensures competitive advantage. Regular ISO 9001 audits are recommended to maintain system effectiveness.
