Continuous Lamination Process
Continuous laminating is a processing method used to produce flat, corrugated, transparent or colored sheets at a high production speed.
Overall, an adhesive is applied to the less absorbent substrate web, after which the second web is pressed against it to produce a duplex, or two-layer, laminate.
This method is preferred especially for the production of foam sandwich panels, refrigerated vehicle panels, truck panels, and RV panels.
Orson has different Types of Resins for Continuous Lamination Process
- Orthopthalate Resin for continuous Lamination.
- Ortho-DCPD Resin for Continuous Lamination.
- DCPD Resin for Continuous Lamination.
Resins for Hand Layup
In the hand lay-up technique, fibers are positioned on or into the mold and wetted by liquid resin.
First of all, the mold surface is treated by release antiadhesive agent to avoid the sticking of polymer to the surface Then, a thin plastic sheet is applied at the top and bottom of the mold plate to get a smooth surface of the product.
The layers of woven reinforcement are cut to required shapes and placed on the surface of the mold. Thus, the resin mixed with other ingredients and infused onto the surface of reinforcement already positioned in the mold using a help brush to uniformly spread it.
Then the other mats are placed on the preceding polymer layer and pressured using a roller to remove any trapped air bubbles and the excess of polymer as well.
The mold is then closed and pressure is released to obtain a single mat after curing at room temperature, the mold is opened and the woven composite is removed from the mold surface.
