Laminating process

Laminated glass

Laminated glass is a type of safety glass that uses a foil to permanently fuse two or more sheets of glass together. In case the glass breaks, it will stick to the interlayer so there are no harmful shards of glass that may cause injury. This type of glass is also suitable in constructions that require glass with fall-though or burglar resistance safety.

When placing this (safety) glass in building, various rules and laws must be taken into account. Depending on the requirements, we can create the glass you need.

At CURA Glass we take great pride in our flexible laminating line which we use to produce our own CURA Safe laminated glass.

Step 1: Lay down

The first step in the laminating process is placing the separate glass sheets onto the laminating line. Our robot places the glass sheets one-by-one on the tilting table. As the tilting table sends the glass towards the second step, the robot picks up the second glass sheet.

Step 2: Washing

The first station inside the laminating line is the washing machine. This is where the separate sheets are cleansed so there are no dust particles, hair or other dirt left that may end up between the laminate.

Step 3: Stacking

After the first sheet has been washed, the laminating line places the chosen interlayer(s) on the glass. Then, the second, washed sheet of glass is placed on top. This can be repeated multiple times until the desired combination is created.

Step 4: Cutting

The interlayers placed are not in the right size yet. This is why the combination will be send further into the laminating line where small, sharp blades cut off the excess along the edges.

Step 5: Heating

During the fifth step, the combination is send through three ovens. The heat will cause the interlayers to attach to the glass sheets and stick them together. When the glass comes out of the oven, the core temperature is measured to make sure the pre-laminate is attached properly.

Step 6: Pick up

During the fifth step, the combination is send through three ovens. The heat will cause the interlayers to attach to the glass sheets and stick them together. When the glass comes out of the oven, the core temperature is measured to make sure the pre-laminate is attached properly.

Step 7: Autoclave

In this last step, the pre-laminate will be permanently bonded under the pressure of 14 bars for three hours long. When the laminated glass comes out of the autoclave, it is ready to be shipped out.
