Q1:What is a profile wrapping line used for?

A1:It is used to laminate decorative films (PVC, PET, veneer, paper, etc.) onto various profiles such as door frames, skirting boards, aluminum profiles, and decorative moldings.

Q2:What materials can be wrapped?

A2:MDF profiles，Solid wood，WPC，Aluminum profiles，PVC extrusions

Q3:What adhesive systems are available?

A3:PUR hot melt adhesive，EVA hot melt，Solvent-based adhesive.PUR is recommended for higher bonding strength and durability.

Q4:How to avoid bubbling or delamination?

A4:By controlling glue temperature, application amount, pressure alignment, and substrate preparation.

Q5:Certain substrates or materials cannot be coated with high-gloss finishes. Which can be finished with high-gloss? Which cannot?

A5:

1) Panels suitable for high-gloss: Melamine-faced panels, wood-plastic composite extruded boards, PVC foam boards, high-density MDF (recommended with hot-melt paint primer). In summary, panels must be of standard thickness with a flat surface.

2) Production environment requirements:Workshop humidity must be maintained above 45%;a dust-free workshop is essential.

3) Adhesive requirements:Transparent PETG must be bonded with transparent PUR adhesive;adhesive flow properties are critical.

Q6:What pressure setting is required for the wrapping machine's pneumatic system to meet production requirements?

A6:0.4-0.6MPA

Q7:Why are some roller mounting rods on coating machines vertical while others are horizontal? What are the differing application effects of each?

A7:The vertical rods serve as roller guide rods, used to position and secure the rollers.The horizontal rods are quick-change brackets. Once a particular profile has been adjusted, the bracket can be disassembled into separate parts and labelled. When production of that profile is required again, it can be reassembled and installed.This

saves time and facilitates operation. saves time and facilitates operation.

Q8:What is the approximate temperature range for the adhesive in the laminating machine? How many temperature settings are required?

A8:Typically, adhesive temperatures are set as follows: laminator pressure plate at 140°C, tube temperature at 130°C, and squeegee at 110°C. These settings must be adjusted according to the specific properties of each adhesive. They should also be determined based on the ambient temperature during production and the heat resistance of the film.
