How Pressure Affects Plywood Quality in Production

Pressure Determines Bonding Strength

Pressure, one of the main factors controlling veneer-to-veneer bonding in plywood manufacture Suitable pressurization in hot press machine allows glue spreads evenly with best stick to satisfy hardness and stable cover between layers.

Powerful Panels, But The Pressure Is Too Low

When the pressure is low enough that veneers do not make full contact with each other. It results in inefficient impregnation, internal cavities, and the risk of delamination under humid, or high load conditions.

Excessive Pressure Is Harmful to The Structure

Too much pressure may force excessive glue out and crush the wood. This causes glue spots, lower elasticity, and sometimes different density within the plywood sheet.

Balanced pressure enhances flatness and densification

The required board thickness and uniform density is achieved with the help of proper pressure control. Surface flatness, which is required for furniture-grade and export-quality plywood are also improved.

Pressure works with temperature and time

Pressure alone is not enough. The process and composition, however, have to be in equilibrium with the holding time and the temperature in a hot press machine. Only the correct combination lets you ensure complete cure of the glue that makes for good-quality plywood
