HERBERT masters all common technologies and can satisfy all requirements according to customer needs The range of products starts with the smallest molds / tread pattern inserts up to the larger sizes like:• bicycle and scooter tires• passenger car and SUV tires• light truck and truck tires• tractor tires up to earth mover tires - (63“ rim size)
Engraved molds (either in steel or in aluminum) Engraved molds are currently the majority of our manufactured molds. Regarding profiles with sipe blades, the sipes are inserted later in the contour or are shaped out of the full material proportional to length, width, height and form.
Steel engraved molds with inserted tread ribs and sipes (Hybrid-Solution)A variation to the completely milled profiles is the combination of lathed tread contour and inserted tread ribs and sipes. With this process extremely high true running accuracy with simultaneously high surface quality can be realized Additionally this variation has the advantage of replacing damaged tread ribs and being able to mill these ribs in spite of a high quantity of sipes.
Molds with casted tread patternTire molds resp. tread pattern inserts with casted tread pattern are considered to be the most common technology when it comes to high quantities with numerous sipes The main casting of the center divided tire mold consists of steel or forged aluminum. Complete tread pattern rings (360°) are fastened to the main casting. The casted tread pattern is a cost efficient way of manufacturing
Puzzle MoldsAlternatively to the classical venting by drillings with inserted vent plugs the possibility exists to exhaust the gases inside the mold through micro gaps. These types of molds are known as “puzzle molds”.The separating lines between the single segments have a tight tolerance, so that the gases can escape but a discharge of the rubber mixture is impossible. Therefore the outer surface of the tire is smooth all around and any refinishing of the tire is eliminated afterwards.
2-piece moldsThe mold back of the 2 piece molds consists of steel or forged aluminum Steel engraved tread rings (360°) are fastened to the mold back.
