The Difference Between Offline And Online Coating Of PVC Skirting

The importance of the PVC skirting board coating process lies in that it not only improves the aesthetics and diversified design of skirting boards by tightly bonding decorative protective materials to the surface of skirting boards but also enhances their wear resistance, moisture resistance, and corrosion resistance, thereby extending the service life of the product and ensuring its stable performance and lasting decorative effect in various environments.

PVC skirting board coating types

• offline coating

• online coating

What is the offline coating?

Offline coating means that after the skirting is formed, it is removed from the production line and then coated on special coating equipment.

Offline coating process

Baseboard forming

The baseboard forming process is completed on the production line.

Cooling and pretreatment

The formed baseboard is cooled and the surface is treated to prepare for the subsequent painting process.

Transfer to painting equipment

The cooled baseboard is transferred to the special painting equipment.

Cleaning treatment

Clean the surface of the baseboard to ensure that there is no dust or impurities.

Gluing

Apply cold glue or hot glue evenly on the surface of the PVC baseboard.

Lamination of coating materials

Lay the decorative material (such as PVC film or wood grain film) on the baseboard.

Compacting treatment

Use a roller or other tool to compact to ensure that there are no bubbles and the bond is firm.

Curing or cooling

Wait for the glue to cure naturally (cold glue) or quickly cool and cure (hot glue).

Quality inspection

Inspect the baseboard after painting to ensure that the surface is flat and free of defects.

Advantages of offline coating

High flexibility

Different batches and styles of skirting boards can be customized according to different customer needs.

Independent operation

The painting process is separated from the production line, which is easy to control and adjust.

Suitable for small-batch production

Offline painting is more flexible for small batches and diversified orders.

Disadvantages of offline coating

Low efficiency

Requires additional transfer and handling processes, and the overall production efficiency is low.

Occupies a large space

Requires additional space and equipment, which increases the demand for factory space.

High labor costs

Transfer and handling require more manual operations, which increases labor costs.

What is online coating?

Online coating means that during the production process of skirting boards, the coating process is carried out directly on the production line without moving the skirting boards out of the production line.

Online coating process

Baseboard molding

The production line first completes the baseboard molding process.

Directly enter the gluing process

The formed baseboard does not need to be cooled and transferred and directly enters the gluing process.

Cleaning process

The baseboard surface is automatically cleaned on the production line.

Gluing

Hot melt glue or other glue is evenly applied on the production line.

Gluing material bonding

The decorative material is automatically bonded to the baseboard on the production line.

Compacting process

The roller or press on the production line is used for compacting.

Cooling and curing

The hot melt glue cools and cures quickly to ensure a firm bond.

Quality inspection

Quality inspection is carried out on the production line to ensure that the product meets the requirements.

Advantages online coating

Efficient production

The coating process is seamlessly connected with the production line, eliminating the transfer step and improving production efficiency.

Small space occupation

The production line layout is compact, and no additional coating equipment and space are required.

The high degree of automation

It is easy to automate the production process, reduce manual operations, and reduce labor costs.

Suitable for large-scale production

For large-scale, standardized product production, online coating is more efficient.

Disadvantages of online coating

Low flexibility

High requirements on production lines and processes, difficult to adjust and replace different styles.

Complex equipment

High-precision automation equipment is required, and the initial investment cost is high.

High process control requirements

Each process step needs to be precisely controlled to ensure coating quality and efficiency.

Selection suggestions

You can choose the appropriate coating process according to your own production scale, product type, and market demand: for small-batch, diversified production, offline coating is more suitable due to its high flexibility and convenient customized production; for large-scale, standardized production, the online coating has high production efficiency and a high degree of automation, which is more advantageous.
