How to Bend a Laminated Sheet
The first step is to determine the radius of the curve. It should be at least three inches. To determine this, draw straight lines perpendicular to the counter edges. They should intersect at a certain point. Then measure backwards from that point to the edge of the laminate sheet. Make sure that the curve will have a straight edge to prevent gaps, bubbles, and distortion.
Heat
When bending laminate, the first step is to measure the radius of the curve. The radius should be three inches or greater. Then, use a T-square to check the edge squareness. Heat bending is more difficult than cold bending, so take your time. Be sure to allow ample time for the laminate to cool.
Once the laminate has reached the correct temperature, you can begin bending the sheet. Wear gloves to protect your hands. Shape the sheet to the edge of the core, and keep moving it to avoid clamping the corners as the laminate cools. If the piece is too stiff, start by heating it up a little bit before moving it.
If you have a heat gun, you can use it to help the plastic bend around the curved surface. But be careful, as too much heat can cause the laminate to lose its shape and crumble. Also, make sure that the laminate is square from top to bottom, so that it will bend correctly around the curve.
Sanding
Before you start working on your laminate, it’s important to know how to sand it properly. For corners and curved edges, you will need to use a belt sander, which is important for getting a flat, clean finish. It’s also a good idea to use a heat gun, which helps to soften the material and make the bending process easier.
A torch or hot air gun will help to bend laminate around tight corners. You can also use a T-square to check that the edges are square. The laminate adhesive will set in a specific temperature when forming, so it’s important to check the temperature of the laminate before starting the bending process.
Inductive heating
Thermoplastic laminates that contain metal sheets can be bent using inductive heating. The heating process softens the boundary regions of the core layer while leaving the central region unscathed. The transfer time between the heating step and the bending operation is less than 5 seconds.
The temperature difference through the laminate depends on its thickness and the flange area of the laminate. For single-sided heating, the temperature difference is as high as 20 degrees, while for double-sided heating, it’s only seven degrees. The temperature difference through the laminate decreases over time as the flange area cools faster than the top side.
One of the advantages of inductive heating is its controlled heating. The process is also pollution-free and uses a high frequency inverter. It is important to choose the proper heating conditions in order to achieve the desired result.
Curves in the middle of the edge strips
To cut curves in the middle of the edge strips of a laminate sheet, start by measuring the width of the edges and cutting them a little longer than you need. Wood will shrink slightly when it changes shape, so measure the strips slightly longer than the finished piece. Use a diagonal line to mark the length of each wood strip. Once you have cut all the strips, add cork to the ends to prevent them from splitting and separating during assembly.
Next, measure the radius of the curve to make sure it is three inches or more. Then, draw straight lines perpendicular to the edge strips of the laminate sheet. Then, measure the length of these lines back to the edge. This will ensure that the edges remain square and that no bubbles or gaps will form.
Using a torch
If you are bending laminate around tight corners, a torch and hot air gun can help. You can also use a post forming machine. Different types of laminates are easier to bend than others. The forming temperature is about 170 degrees Celsius. A T-square is an important tool for identifying a square edge.
It is crucial to choose the correct tool for the job. Utility knives and laminate shears are both useful tools, but laminate shears are much more expensive than utility knives. While utility knives are cheaper and faster, they do not cut corners as well as laminate shears. In addition, utility knives may cause a bit of cracking and may not be as accurate.
