Knotwood aluminum is technically designed to not only look good, but withstand the test of time. Knotwood’s true beauty doesn’t rest in its durability and aluminum capabilities, but rather the natural beauty and timeless appeal of its lifelike wood finishings are what sets it apart.
Extruding Knotwood Profiles
The process begins by heating the stock billet material. It is then loaded into the container in the press. A dummy block is placed behind it where the ram then presses on the material to push it out of the die. Afterward the extrusion is stretched in order to straighten it.
The next stage in Knotwood’s process involves powder coating. Electrostatic guns will be used to make 80-120µ (microns) powder paint layer. Polymerization will be performed afterwards by heating the profiles to 220 degree Celsius for 30 minutes. The base coat that is applied is very durable and scratch resistant. This coat also serves as protection of the aluminum from external factors such as abrasion, corrosion, weather, humidity and UV damage.
The powder coated aluminium is wrapped in one of Knotwood’s many films and set on a conveyor system. We then vacuum the air from the film around the aluminium. The conveyor transports the aluminum into the oven, under heat and pressure the film transfers the Knotwood image onto the aluminum.
