The unreasonable process technology of Zero Formaldehyde Doors causes deformation

2026,11,06

The material properties on both sides of an Simple Style Zero Formaldehyde Doors should be inconsistent. Due to the different thicknesses of the decorative materials, the distance between the adhesive layer on both sides of the Simple Style Zero Formaldehyde Doors and the centerline of the Simple Style Zero Formaldehyde Doors is not consistent. Although the stress generated by the adhesive during the curing process is the same, the bending deformation of the Simple Style Zero Formaldehyde Doors is caused by the different force arms.

Therefore, in the production process of the product, it is necessary to require that the thickness, type, moisture content, and structure of the decorative materials be the same. Some small brand factories use good materials on the front and cheap materials on the back during processing and production, which can easily cause deformation.

For example, Zero Formaldehyde Doors cannot immediately proceed to the next processing step after being coated with decorative materials. This is partly because the adhesive has not fully cured, and partly because the adhesive contains a large amount of moisture that does not spread evenly in the bonded material.

For products processed by hot pressing, the temperature is much higher than the ambient temperature, and subsequent processing needs to be carried out after the product temperature and ambient temperature are balanced. This balancing process is professionally called 'Chenhua'.

After hot pressing, it can be directly stacked and stacked for aging, or a drying machine device can be used to lower the temperature of Zero Formaldehyde Doors in a shorter period of time, achieving a balance between the product and the ambient temperature and shortening the aging time in the later stage.
