For Plywood, There will be always different core types, which will be different with one another on properties such as flatness, dimensional stability, screwholding ability, bending strength, and visual edge quality.The relative importance of specific properties in a particular application of the product helps determine the appropriate core type that should be used.Following are the Core Types and relative Advantages and disanvantages of them for reference.
Basic Types of Plywood Core:
---Combination Core:Face Veneer+Veneer+MDF/Particle Board+Veneer+Back Veneer
Key Advantage:Consistent flatness, Good screw-hold ability, Lighter Weight
---Lumber Core:Face Veneer+Veneer+Lumber+Veneer+Back Veneer
Key Advantage:Good Bending strength, Good screw-hold ability
---MDF Core:Face Veneer+MDF+Back Veneer
Key Advantage:Consistent flatness, Cheaper Cost
---Particle Board Core:Face Veneer+Particle Board+Back Veneer
Key Advantage:Consistent flatness, Cheapest Cost
---Veneer Core:Face Veneer+Veneers (Grain Altered layer by layer)+Back Veneer
Key Advantage:Excellent Bending, Excellent screw-hold ability, Lightest Weight |
