Powder coating manufacturers are gaining popularity. Powder coating is a dry finishing process that has become extremely popular in Australia and other American countries since its introduction in the 1960s. Representing more than 15% of the total industrial finishing market, the powder is used in a wide range of products. More and more companies are opting for powder coatings for high-quality, durable finishes, allowing maximum productivity, improved efficiency, and simplified environmental compliance, and so the demand for powder coating manufacturers is also increasing.
When all the raw materials used in powder coating are mixed, they remain solid. Polymers and other components such as pigments, fillers, cross-links, etc., are correctly weighed in the mixing vessel. The contents are then mixed to form a homogeneous mixture.
Let’s have a quick look at the method powder coating manufacturers use to create powder coating colours.
Extrusion
The pre-MX is then fed into the extruder, that is maintained at a precise predetermined temperature. This temperature helps in diluting the polymer. The temperature has to be accurate to get the right result, and only a professional powder coating manufacturer can get it right. Too high a temperature will give a low melting viscosity, low shear, and poor pigment scattering, which will not result in a coating with the desired performance.
Milling or grinding
The chips are then ground to ensure a suitable particle size distribution for the application process, such as electrostatic spray fluid bed dipping. For this, a pin-disk or hammer mill is employed. In modern mills, an internal classifier is used to limit the maximum particle size large-sized particles are continuously fed to the mill.
Sewing
Regardless of the method used to produce the powder, it is the final operation of the process. This operation removes any large particles passing through the mill and achieves a finely tuned particle size distribution.
Powder storage
After final sieving, the powder is stored in a tightly closed container in a dry place to prevent possible contamination or potential increase in humidity. Powders should be kept away from moving parts as frictional heat can cause the powder to fuse and possibly heal inside the container. The Powder Coatings Manufacturer should be kept at as low a temperature as possible for long-term storage, significantly below 25oC.
What you need to know about powder coating cost estimates
Whether you need a commercial-scale application, like your rim or wheel powder-coated, or wish to apply coating powder yourself, you've come to the right place. So you want to know how many products and services are related to powder coating cost. This article provides an overview of powder coating costs for industrial applications, DIY powder coating, and all other powder coating services.
Different aspects of the project determine powder coating cost and price:
The amount of pretreatment required
Type and colour of the powder
The surface area of a part or object
Application Procedure
Uses of Powder Coating:
✔ Machinery
Appliance companies often benefit from using powder coating in ovens, refrigerators, washers, dryers, dishwashers, air conditioners, water heaters, microwave ovens, and many other places.
✔ Automotive
Powder coating is used in many automotive industry parts, including hubcaps, bumpers, wheels, decorative trim, door handles, truck beds, accent parts, filters, radiators, and various engine parts. Auto companies have begun to include a clean powder topcoat to help increase safety.
Conclusion:
With all the benefits that come with powder coating vs. liquid paint, your parts are wise to be powder-coated. But if you do not have the tools for this, you will need to look for powder coating services externally and connect with the best powder coating manufacturer.
