Check the Quality of The Core and Sort Out The Core

Ensuring the strength and consistency of plywood begins with inspecting the core. At TTP, a strict quality inspection process is applied to check the pattern, structure, and moisture level of each core sheet before it is used in production.

Why Core Quality Matters

The core is the internal foundation of plywood. If the core is weak, uneven, or has defects, the final product will suffer in strength, durability, and surface finish.
That’s why TTP prioritizes core testing and classification as the first and most important step in quality control.

TTP’s Core Inspection Standards

To ensure only high-quality sheets are used, each core must meet the following criteria:

• Flatness: The core must be even and not warped.
• No Holes or Breaks: Sheets with missing parts or torn areas are removed.
• Full Edges: All four edges must be intact for alignment during pressing.
• Correct Size: Each core must meet the designated dimensions for product consistency.
• Moisture Level: Humidity must be below 18% to avoid warping or delamination.

Classification Process

After passing the initial visual and structural tests, cores are classified into groups based on:

• Appearance
• Thickness Uniformity
• Surface Defects
• Color Matching

This helps the factory assign the right core to the right plywood product (e.g., commercial plywood, film-faced plywood, packing board).

Pattern Test Procedure

Pattern testing is conducted to check the internal strength distribution of the core.
QC staff assess how the core responds to pressure and identify weak zones that may affect final board performance.
Only cores with balanced and strong patterns are approved for further processing.

The Role of TTP’s QC Team

TTP’s Quality Control (QC) team has years of experience. Their job includes:

• Checking every incoming core sheet manually
• Using moisture meters and size tools
• Classifying sheets according to grade
• Rejecting unsuitable materials

Their work ensures that only top-quality cores go into TTP’s finished plywood products.

Final Sorting and Use

Once classified, cores are grouped and sent to production based on product type and thickness requirements.
Lower-grade cores may be reused internally for packing boards or low-spec applications—nothing is wasted.
