Challenges for surface optimization in the plastics industry

Accelerated production speeds and the more complex design of rubber and plastic parts are placing ever-greater demands on the surface systems used in production processes. Besides excellent non-stick properties and good demoldability, environmental aspects such as the use of conventional separating agents are gaining in importance when it comes to the processing of plastics.

Efficient and reliable coatings

Due to the growing number of challenges, the plastics industry needs sophisticated surface coatings. Our efficient and reliable surface technology improves your cycle times, reduces your cleaning efforts to a significant extent and results in increased productivity. Plastic coatings by Aalberts surface treatment become firmly anchored in materials such as steel, stainless steel, aluminum, copper, ceramics and support elements which are also made from plastics. Our FDA-approved coatings are suitable for plastic parts which come into contact with food.

Let us know what your requirements are. Be it quicker cleaning, less wear and tear and/or ideal traction properties, we will find the perfect coating for you.

  • Non-stick coating for flat nozzles in film manufacturing

  • Better mold removal in injection molding via nonstick coating

  • Traction and non-stick coating of cylinders and rollers the foil processing

Customized coating systems with special reinforcing materials

Our comprehensive range of premium products fulfills any and all of the requirements the plastics industry places on surface coatings. Where required, an intermediate metal or ceramic layer may be applied by thermal spraying after conditioning. Such intermediate layers create a high degree of surface hardness.The subsequent plastic coating is applied using infusion technology based on powder coating. Our polymer and fluoropolymer finishes additionally offer excellent corrosion protection and a high resistance to chemicals.

Accordingly, the range of applications is very versatile:

  • Welding mirrors
  • Rollers (smooth rollers and structured rollers)
  • Sealing bars
  • Molds and injection molds
  • Glue nozzles and spray nozzles

In order for you to get a better impression of our tailor-made coating systems, we have compiled a small selection of the surface optimization solutions we have developed for the plastics industry.

  • During the production of special films, large sheets of film have to be double-coated with adhesive whose material properties differ depending on the application. After that, the film is dried using several flat fan nozzles arranged in a row. These nozzles blow air onto the sheets of the film. At the end of the plant, the cooled film is cut and finally wound onto rolls. The nozzles need to be cleaned after each production job. Depending on the adhesive used, the intensity of the adhesions differs so that it might take up to 30 minutes to clean a single nozzle.But the duration of the cleaning process is not the only disadvantage.In the long run, this mechanical cleaning process will damage the surface and thus the functionality of the nozzle.

    When using TempCoat® (formerly known as ChemCoat®) for surface optimizations in the plastics industry, the nozzle surfaces' non-stick properties are considerably improved. Less adhesive remains stuck to the nozzles, the adhesive residues can be easily wiped off with a cloth.What is more, the nozzles become resistant to wear and tear.Since the coating does not affect the electrical conductivity, the film does not become electrically charged. Thanks to the coating, the efforts for cleaning the flat nozzles can be reduced by 95%, which results in significantly increased productivity.

  • The manufacture of isolators for energy facilities involves the production of injection-molded parts. First, a liquid elastomer is injected into the steel tool (consisting of mold core, mold shell and base plate) under pressure and heat. After cooling, the finished component is removed from the mold. During the demolding process, adhesions frequently occur between the bridge of the injection channel and the finished product. Any crevices and fractures must be reworked using separating agents.

    In order to improve the demolding process, especially in the area of the injection channel, the experts working at Aalberts surface treatment use TempCoat® (formerly known as ChemCoat®) surface coating for the plastics industry. This durable non-stick coating ensures that the finished parts can always be perfectly removed without causing any crevices and fractures.

    The advantages of this surface finish speak for themselves:

    • Easier and quicker demolding
    • No rejects
    • Cost savings with regard to release agents
    • No undesired damages to the mold, long service life
  • Film strips for cigarette pack wrappings are processed using rollers between which the material is transported back and forth. The film must be glued, laminated, cut and packed. Due to the rollers' smooth surface, the functionality might be limited: the film slips off or tears under excessive tension. The production needs to be interrupted and a lot of material gets lost due to slippage when the plant is restarted.

    Production processes in the plastics industry can be considerably improved when rollers are coated with TempCoat® (formerly known as ChemCoat®) and PlasmaCoat®. The improved traction properties keep the film from slipping off or tearing. Furthermore, the rollers become resistant to wear and tear, which keeps the film from getting damaged during cutting or punching processes. The rollers' required electrical conductivity remains unaffected.Not only does the use of surface technology avoid losses caused by production downtimes, but it reduces the production costs.
