Powder Coating

Powder Coating Production Line

Powder coating is a color-finishing technique in which powder is used in lieu of paint. The powder is applied with spray tools and heated to a chosen surface to form a color coat.

The main difference in comparison to conventional liquid paint is that powder coating does not require a solvent to keep the binder and filler parts in liquid suspension form.

Powder coating achieves a thicker and more consistent finish than you usually get with spray paint.

Making powder coatings is a multi-step process, essentially composed of batching, premixing, extrusion, and particle size reduction. In this case, it can be called semi-continuous because it starts out as a batch process (weighing and pre-mixing) but then moves to a continuous process (extrusion and milling).

Basically, a compilation of somewhat dissimilar materials is blended, melted, cooled, and then pulverized.

Tiermax high-performance extrusion coating lines are the ideal solution, as they are specifically designed to meet the enormously diverse requirements for coating products. Our high-speed extrusion coating lines set industry standards while allowing for frequent product changes.

Advantage of Tiermax Powder Coating Production Line

  • Premixing equipment is designed for an optimal range of vessel filling.
  • Specially adapted upstream equipment for feeding
  • Touch display process control system that regulates and monitor the mixing process in real time.
  • The production line can be adjusted for formulas that contain difficult-to-disperse components, such as carbon black pigment, in extruder a slower screw speed might be needed to achieve adequate dispersion.
  • Gentle handing of raw materials and product.
  • Easy to maintain and clean

Feeding and Dosing

The first step is to weigh the raw materials according to the ratios specified in the master formula. The weigh-in takes into account the quantity required by the customer order as well as the capacity of the premixing vessel.

Tiermax high-accuracy feeders are made to accurately dose raw materials (loss in weight, volumetric) or liquids. They can be used for both (loss in weight). 

Powder Coating

Pre-Mixing System

The premixing step makes the raw materials mix more homogeneous so that a consistent mixture can be fed into the extruder. It also breaks down large resin particles so that the mix can be fed into the extruder more quickly.

Choosing the right mixing system is essential to the operation’s success.
