Fancy turning your surface into a work of art?

plastics industry

Higher production speeds and more complex design of rubber and plastic parts place increasing demands on the surface systems used in the manufacturing process. In addition to excellent nonstick properties and ease of removal from molds, factors frienly to the environment, such as the substitution of conventional release spray, are gaining importance. High-performance, reliable coatings improve cycling times, drastically reduce the cleaning requirements and help to increase productivity in production. Impreglon offers its customers a wide range of surfaces with different or combined properties:

  • Excellent nonstick properties
  • Good sliding properties
  • Extreme resistance to wear
  • High temperature resistance

Film manufacturing (nonstick coating)

Surface nozzles in film manufacturing

When manufacturing special films, various types of adhesive are applied to both sides of long sheets of film depending on the specific application. The film is then dried by a series of surface nozzles that blow air onto the sheets. At the end of the line, the cooled films are cut and wound onto rolls.

Quick, easy cleaning

The nozzles have to be cleaned after each new production job. The amount of residue on the nozzles depends on the adhesive used. The cleaning process is time consuming and can take up to half an hour per nozzle. With over 30 surface nozzles per line, cleaning can easily take an entire day. When order specifications change frequently, the cleaning time increases considerably. The mechanical cleaning which is often required damages the surfaces of the nozzles over time.

ChemCoat®

ChemCoat® dramatically improves the nonstick properties of the nozzle surfaces. Less adhesive sticks to the nozzles, and any remaining residue can be easily removed with a rag. The nozzles are protected from wear. Electrical conductivity is retained despite the coating, so the films do not become electrically charged.

Low wear, minimal cleaning required

The effort required to clean the surface nozzles was reduced by 95% after the nozzles were coated. Productivity increased considerably, because entire cleaning shifts could be eliminated.

High-quality nonstick coatings and slide coatings

The ChemCoat® coating procedure creates a high-quality surface coating with excellent nonstick properties and/or very good sliding properties. Thanks to our special infusion process, our ChemCoat® polymer coatings and fluoropolymer coatings are particularly well anchored to the substrate.

ChemCoat® nonstick coatings can be applied to aluminum, steel, stainless steel, ceramics and some coppers. They are used in particular in applications requiring good sliding and nonstick properties, as well as high wear resistance.

Coating thicknesses 7 µm to 70 µm
Temperature range: -40 °C to +260 °C
Surface roughnesses (Ra): up to approx. 1.5 µm
FDA approved: yes, with certain coating types
Fluoropolymer layer

Insulators (nonstick coating)

Insulators

Molded parts are made using injection molding for the production of insulators for energy plants. In the process, the liquid elastomer, pressurized and heated, is injected into the steel die (consisting of a mold core, sheath and bedplate). When the mold has cooled off and the elastomer part has hardened, the mold is opened and the finished part removed.

Residue-free mold removal without cracks

Residue between the bridge of the injection channel and the final product repeatedly sticks when the mold is removed. This results in cracks and fractures that have to be reworked. Release spray must be used so that the parts can be dislodged from the mold without leaving residue.

TempCoat®

TempCoat® improves mold removal, particularly in the injection channel. The durable nonstick coating improves the removal of the finished parts over the long-term, without cracking and fractures.

Less waste, greater efficiency

Quicker and easier removal from the mold. No waste. Reduced costs since release spray is no longer needed.

Wear resistant slide coatings with nonstick properties

The TempCoat® coating procedure creates polymer and fluoropolymer layers with outstanding nonstick properties and very good sliding properties.

With additional reinforcement layers, slide coatings can be combined with high resistance to wear.

TempCoat® coatings can be applied on aluminum, steel, stainless steel, copper, ceramics and even plastics.

Coating thicknesses: 10 µm to 100 µm
Temperature range: -40 °C to +285 °C
Surface roughnesses (Ra): up to approx. 1.0 µm
FDA approved: yes, with a few coating types

Film packaging (traction and nonstick coating)

Film packaging

The plastic wrap on cigarette boxes is made by passing strips of film back and forth through rolls and reels. The foil has to be glued, laminated and cut to size at the highest possible line speed.

Optimal use of material, no waste

The smooth surface of the rolls can cause the film to slip through or tear if tension is too high. Production is interrupted and a substantial amount of material is lost due to slippage when the line is started up again.

ChemCoat® and PlasmaCoat®

Coating the cylinders and rollers with ChemCoat® and PlasmaCoat® considerably improves the production flow. The optimized traction properties prevent the film from slipping through or tearing. Also, the rolls are treated with a wear-resistant coating that protects them from damage when the film is cut or stamped. The necessary electrical conductivity of the rolls is not affected by the coating.

No interruptions, cost efficiency

Losses due to interruptions in production are eliminated and production costs are reduced.

Wear-resistant combination coatings

The PlasmaCoat® coating procedure combines the outstanding surface hardness and wear resistance of thermally sprayed metal or ceramic coatings with the nonstick and sliding properties of polymers and fluoropolymers.

PlasmaCoat® combination coatings also offer very good traction properties with various degrees of surface roughnes and profiles. An embedded metal or ceramic coating can be used as a substrate for the coating that protects from wear.
