Which flocking device for which application?

Crafting, Hobby

For smaller to medium areas, e.g. greeting cards, model landscapes, fashion railroads or even embellishments, the HOBBY Flocker Pro is your first choice.

Small series, textile, flat parts, automotive

You would like to create small series, but do not want to buy an expensive machine? You would like to flock textiles, embellish small to medium parts of cars, refine wooden boxes or create art objects? Then the MINI Flocker Evo is the right choice for you!

Series production, industrial applications

For professional industrial applications we recommend our EASY Flocker.
With it you can flock practically anything. The voltage and amperage can be precisely set via the membrane keypad and conveniently read via the display. This makes this hand flocker so versatile.

Industrial application, automotive, 3D parts with internal geometries

For recesses and parts with 3D interior geometries (e.g. glove box), pure electrostatic flocking alone is not sufficient. Here, air support must be used so that the flock overcomes the Faraday cage and reaches the interior. This process is called electrostatic-pneumatic flocking. For this purpose we have developed the AIR Flocker Pro.

Range of use

What can be flocked?

It can be flocked anything on which the adhesive holds. So there are no limits to your imagination: paper, wood, glass, porcelain, plastics, textiles...

Where can you find flocked surfaces?
  • Glove box in car
  • Wallpapers
  • Greeting cards and books
  • Packaging (perfume, jewelry, ...)
  • eyeglass cases
  • Window profiles in car
  • Fashion and design
  • On handles of tools
  • Cosmetic applicators for applying cosmetics
  • Corona test sticks
  • orthoses
  • Air mattresses
  • Toys (Playmobil, Filly,...)

Why Flock?

Optics

The fiber surface conveys a higher value than an unflocked surface. Flocking can be either partial or full-surface.
By selecting suitable flock types, further optical effects can be incorporated in addition to the color.

Haptics

The aligned fibers result in a velvet-like surface that can be adjusted from soft to hard depending on the flock material used and the fiber length.
Fibers with low titer and/or longer cut length have a soft feel. Fibers with a high titer and/or short cut length have a rather rough feel.

Noise prevention

Due to the flocked surface, no noise occurs on contact.

This is why, for example, glove boxes, storage compartments, center consoles, eyeglass compartments, but also coffee cups and tableware are flocked in cars.

Another application is the flocking of microphones or their covers to prevent wind noise.

Refraction of light- and sound waves

Flocking has a damping effect by breaking sound and light waves many times in the flocking structure.
This effect is used in the flocking of sound insulation elements, engine covers or the inside of side channel compressor housings.
This effect also minimizes stray light in optical housings or prevents the reflection of numbers on players' jerseys or other lettering during sports broadcasts.

Adhesion and sliding effect

Adhesion and sliding effect

Surfaces with a good grip

Flocking with flock types of high titer and short cut length produces a very grippy surface. The function of tool handles of all types can thus be optimized.
By flocking screwdrivers, for example, a higher torque can be transferred from the hand to the screwdriver. Even with dirty or greasy hands, a secure grip is ensured.

Compensation of tolerances

The flocking acts as a perfect gap filler. In addition to compensating for gaps, e.g. in interior parts in the car interior, flocking prevents unnecessary rattling.
In the case of belt sliders in the vehicle interior, the flocking creates a double effect. In addition to damping running in the guide, rattling noises inside the guides are prevented.
The flocking can either be applied directly to the component or as tape to be stuck onto the required areas.

Insulation against heat and cold

The flocking covers only approx. 10% of the flocked surface, the calmed air between the fibers creates an insulating effect. Partial flock dots as spacers between several film layers creates an ultra-insulating material.
Flocking the inside of boat hulls or snow groomer cabins shifts the dew point and reliably prevents condensation.
Flocking of linings on heating elements or sauna ovens prevents burns in case of skin contact. Handles on pneumatic tools are flocked to insulate against cold.

Depot effect between the fibres

The free space between the flock fibers can be used as a depot for many substances. Typical applications are paint rollers, painting tools or applicators for cosmetics.
Flocked cannula ends for applying dental primer also serve as micro-brushes.
Flocked spatulas or rods are also often used for taking saliva samples, the so-called corona swaps.

Functional surfaces

The following is a small excerpt of other flock applications:

Gentle material transport:
Conveyor belts, devices, grippers, support points are flocked in order not to damage the material to be conveyed or moved. The contact surface can either be flocked directly, or a flock tape can be partially applied.

Cleaning systems:
Suitable flock fibers can be used to create very effective cleaning systems. Typical applications are floor mats for laying out, but also carpets. Rotating brushes are often used in textile machines for cleaning spinning waste. Partially flocked cleaning cloths or sponges also remove stubborn dirt.

Fouling prevention:
Aquaculture nets become unusable over time due to algae and crustacean fouling. Flocked nets remain without fouling. The same is true for flocking boat hulls.

Bonding:
Flock as an intermediate layer between different partners that are difficult to bond permanently.
Examples are architectural elements made of styrofoam molded parts with plaster overlays, or orthotic parts made of silicone that are to be bonded to plastic. In both cases, the part to which flock is to be applied is flocked beforehand, and the problem partner then anchors itself mechanically in the flock.

Active surfaces

Fibers can be produced with special finishes. This finish can be chemically adapted to the respective application. Another possibility is to finish the fibers after flocking by an additional application step

Conductivity by metallization:
Flock fibers can be coated with elemental silver. A small admixture of these fibers results in a very good electrically conductive flock coating to the substrate.

Surface area enhancement:
Filter elements are given a larger surface area by flocking. The flocking can serve as an active ingredient depot, or in the wet area as a 'habitat' for microbiology.

Which materials are needed?

Flock fibres

Flock is available in different materials, fiber thicknesses, cut lengths, and finishes.
Common flock materials are:

Synthetic fibers of polyamide, polyester (for automotive parts and profiles)
Organic fibers from artificial silk, cotton (for textile applications and household)

Usually flock consists of non-conductive material. In order to align and accelerate the fiber in the electric field, a defined conductivity on the fiber surface is required. For this purpose, the fiber is chemically prepared accordingly by the flock manufacturer.

Adhesive

Adhesive manufacturers offer different adhesive systems to suit different materials.
Depending on the application, the adhesive is applied by brushing, rolling, squeegeeing or spraying.
It is also helpful to dye the flock adhesive with pigments in the same color that is to be used for flocking. This makes the flock image appear even denser and more valuable.
