Powder painting

To meet the demands of the contemporary market and follow the search for innovative methods of development of the company, in 2013 project of powder coating was implemented in the manufacturing plan Neapco Europe Sp. o.o. in Praszka.

Currently, we have our own production hall in which two lines of powder coating were launched – one with modern surface preparation prior to painting, using Oxilan technology. This technology allows for a very high corrosion resistance, which meets the expectations of even the most demanding customers. It is worth mentioning that the process is almost 100% automated and completely safe for the environment.

We specialize in painting components (elements of driveshafts) for such reputable car brands as Mercedes, Volkswagen, Ford, BMW, GM and Opel. Our highly skilled team is constantly looking for new solutions and optimisation of the process, because we are convinced that we can always improve, and hence be unrivalled.

Powder coating
process

Powder coating is a technology that transfers powder paint onto metal parts, and then we need to harden the surface.

This process consists of several stages:

Stage 1: “washing” the part

The basic requirement is the purity of the detail to be painted. In the workpiece any contaminants that were on (an effect of the earlier treatment) must be removed. The problem here is mainly oiling of the parts in the preceding processes, as well as preservatives used to protect the parts in the interoperable processes or transport (when the painting process is located in a separate location).

In the process of “washing” different technologies are used, including different elements, whose primary task is to prepare the surface for powder painting. Improper preparation, failure to maintain the rigors of the process parameters of baths can result in the paint falling off. Restoration of badly painted details for re-painting is laborious and costly – so-called “cost of poor quality.”

In the washing process or during the next step additives for improving adhesion or corrosion protection can be applied.

Stage 2: painting the part

Applying the paint onto the part with a special painting sprayer. Administration of the paint is assisted by compressed air, which makes the loose paint material takes on the characteristics of the liquid. Electrified particles in the paint bring uniform adhesion to the painted surfaces.

Stage 3: hardening the paint

For this purpose, high temperatures – in the range of 180-200 ° C are used. Both, applying and hardening require compliance with specific technological parameters for the quality consistent process performance, primarily taking into account customer requirements. In this stage, proper protection of those parts that cannot be painted can be a problem – which can even result in manual application of covers onto particular areas. Naturally, the more intricate part, the more time consuming and expensive protection operation can be.

Powder coating is a very popular method because it provides a perfectly smooth surface, free of any type of stains, or wrinkles typical of other technologies. It is used where the appearance of the part is important to the customer.

Advantages of powder coating:

  • Very good anti-corrosion and aesthetic properties of the products (resistance to weathering);
  • Long-term durability, flexibility and resistance to chemicals;
  • High scratch resistance with a very good decorative effect;
  • High performance;
  • Saving of paint;
  • Possibility to give gloss, satin, matte, etc., (depending on the applied paint);
  • No harmful impact on the environment or human;
  • High speed of carrying out the process of painting;
  • High precision.

Powder coating is today of great interest and chosen more and more often. The popularity of powder coating results from the advantages and benefits it gives.
