PA 6.6 AKROMID® A3 GF 50
Combs with high strength and good wear properties made of plastic are often used in barbering. Just as an accurate machine haircut cannot do without professional hand tools, its production by injection molding requires high precision. The company H. Liebke GmbH from Bremen, active in plastics processing and toolmaking, manufactures them.
The comb is very light thanks to glass fibre-reinforced plastic. It measures 8½" and lies well in the hand. The wavy teeth with parallel arrangement make it possible to keep the hair in the desired length while cutting. A precise tool and a precisely adjusted processing without fluctuations are necessary for the production.
A material with a high batch consistency is also required, which is particularly important for the precisely adjusted process. Christoph Gerling, Business Development Manager at the Hamburg-based plastics distributor K.D. Feddersen therefore recommended AKROMID® A3 GF 50, a polyamide 6.6 compound with 50 % glass fibre reinforcement from AKRO-PLASTIC.
ICF Compounds for Antistatic Combs
Depending on the intended use, Liebke manufactures various professional combs made of different materials from our portfolio. The requirement “antistatic” can be fulfilled very well with the ICF compounds with 20 % sustainable carbon fibres from AKRO-PLASTIC. Carbon fibres are often used as fabrics or scrims. Hereby large amounts of edge sections are produced which are no longer usable for the original purpose. The compounder has become aware of this previously unused material and has developed a process for its preparation.
The aim of this process was to convert the sections into a form suitable for the compounding process, i.e. to completely preserve the properties of the carbon fibres while making them easy to dispense as well. The base material was fabric cuttings that had been produced, for example, in the bodywork production at BMW.
“Compared with other compounds, e.g. with conductive carbon black, we produce a good surface and high strength with the ICF fibre at a very good price-performance ratio,”
