Powder Coating On Aluminium Process
Damage to the aluminum flake will occur during the powder coating manufacture process that imparts the highest shear density namely in the extruder. This final step allows the powder coating to harden and complete the powder coating process.
Cooling the aluminium.
Powder coating on aluminium process. Powder coatings may be a little less smooth than some liquid coatings due to the fact that the material is almost 100 percent solids. Without solvent the coating has to depend on the melt and flow phase of the cure cycle to achieve a smooth finish. The powder used for the process is a mixture of finely ground particles of pigment and resin which is sprayed onto a surface to be coated.
Powder coating is the process of spraying electrostatically charged paint in powder form onto your extrusions. Powder coating is a process of coating metal with a plastic finish applied in powder form and baked to a fluid state to bond it to the metal surface. The pre treatment process involves removing dust grease and any other foreign particles.
Tahap powder coating. Powder coating has many advantages over traditional liquid coating. Some powder coating ovens running above 400 f have been known to reduce the temper on such aluminum alloys.
And that s to allow the aluminium to cool. If we look at the extrusion stage whether for single screw reciprocating or twin screw co rotating types both temperature. Although certain aspects of powder coating can be tricky it s certainly not difficult especially for an enterprising soul.
It s better for the environment applies thicker without running and is easy to style with. 3 powder it when fully prepped and dry your metal project will be ready for powder coating. After heating the treated aluminium there s just one more step in the powder coating process.
So it s very important that the surface of every extrusion is properly pre treated. The coating itself is done through an electrolysis process whereby the metal object is positively charged in order for the powder to be attracted to it and bond well during the next stage. Pengecatan atau pelapisan dengan menggunakan metode pengecatan powder coating ini sering di gunakan diaplikasikan pada benda yang terbuat dari aluminium atau besi.
Once the aluminium is removed from the curing oven it is left to cool for several hours. Pertama produk metal dibersihkan treatment proses kimia terlebih dahulu kemudian dilapisi dengan cairan penahan karat dan dikeringkan. The charged powder particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven.
The result is a uniform durable high quality and attractive finish. Considering that the motor supplier cannot predict the cure temperature used by the powder coater they advise against powder coating their products. The heat of this oven melts the powder into a coating which melts uniformly over the surface of the aluminium.
Unlike liquid paint powder coating doesn t require a solvent. How the powder coating process works. 1 pre treat the aluminum surface.
