Why Do Pinholes Appear? Outgassing on Castings and Galvanised Parts
Pinholing is usually a fault in the substrate rather than the coating: porous castings and hot-dip galvanised surfaces release gas as they heat up, and the film is punctured before it gels. This article settles the choice between a preheat zone, a degassing powder and a slower oven ramp on the basis of the line's temperature profile.

How Many Containers Does a Powder Coating Line Fill? Module Split and Loading Plan
The answer to how many containers a powder coating line fills lies in the cross-section of your largest part, not in the throughput of the line. Where the line is split into modules, which module goes into a container and which onto a flat rack, and why the loading order dictates the assembly order on site.

When the Resin Changes, What Must the Oven and Booth Change?
The resin family decides far more than where the coating can be used; it sets the oven's working band, the dwell time, the conveyor speed and the exhaust capacity. This article compares the four powder families not by "which is better" but by what each one asks of your plant.

What CE Marking Covers on a Powder Coating Line - and What It Does Not
There is no such thing as a CE certificate for a powder coating line; CE is a manufacturer declaration. A line linked by conveyor is one machine in the eyes of the law and carries one CE mark. What belongs in the technical file, what to write into the purchase contract, and who signs what at commissioning.

Why ±3 °C Oven Uniformity Matters — And Where Coating Defects Come From
Powder does not cure at a temperature; it cures on a time-temperature curve. If one corner of the oven is 15 °C colder than another, one part in the same load is under-cured and another yellows. ±3 °C is the practical limit for that spread — and air circulation, not heater power, is what decides it.
