Great flexibility during installation

With the temperature channels of the tempflex series hotset expands the creative scope of the designers in tool and mold making. Thanks to the reversible flexibility of this corrugated hose solution made of stainless steel, the cooling and heating channels in the cavities can be freely laid out. In this way, it is very easy to create installation patterns with tight radii that are close to the cavity outlines. In addition, demanding deep drillings can often be avoided.

Tightly packed interiors, faulty drillings or even overly ambitious deadlines - such adversities are all too familiar to toolmakers in plastics and foundry technology. In such cases, the use of tempflex temperature channels from hotset can prove to be an equally user-friendly and cost-effective solution. This is a flexible corrugated hose product made of stainless steel, which can be used for quick and easy realisation of cavity-close temperature control. The toolmaker and his design engineer have the possibility to design even complex structured channel layouts with small bending radii of only 10 mm without extensive deep drilling. "Our tempflex temperature channels are simply fitted into previously milled grooves and connected to the media supply with the ends of the plug-in couplings. They can basically be used for cooling, preheating or heating of molds used in injection molding, extrusion, thermoforming and casting", says hotset project engineer Bernward Seeberg.

Applicable up to 250° C and 10 bar

Manufacturer hotset - known for innovative heating element and thermodynamic solutions - offers the tempflex temperature channels as standard in lengths from 200 to 2,600 mm and in cross-sections of 8.0 x 8.0 mm and 12.0 x 12.0 mm. The corrugated hose is always made of stainless steel, while its plug-in couplings are either made of brass (metric) or stainless steel (inch). At operating temperatures of up to 250° C the flexible temperature channel from hotset can be used for applications with oil as well as with water. "The tempflex is designed for a maximum pressure of up to 10 bar and is designed in such a way that it only has a minimal pressure resistance compared to the usual 90° deflections - even with tight installation radii", emphasizes Bernward Seeberg.

Versatile problem solver

Especially in the recent past, hotset's development engineers have further refined and improved the tempflex, so that the adaptable corrugated hose is now available to tool manufacturers as a solution for very different tasks. As its application makes expensive and time-consuming deep drillings superfluous, the tempflex can also be used for the quick execution of rework or corrections on existing mold cavities. Sometimes it proves to be a cost-effective retrofitting mold for the revival of older or discarded molds. "Even if subsequent optimisations of the temperature control system of a complex mold are pending, for example because its interior is now too heavily built up or more efficient cooling is required in certain sections, the tempflex always provides valuable services", reports hotset project engineer Seeberg.

Low maintenance and corrosion resistant

Apart from its flexibility and versatility, hotset's tempflex scores as a low-maintenance and corrosion-resistant temperature control solution. It does not clog, is very easy to handle and can be installed and exchanged without the use of special tools. Matching the tempflex, hotset's range of accessories includes metric and inch quick couplings for 1/4" sleeves with or without cut-off valve. On request, the customer also receives the tempflex in special lengths of more than 2.600 mm.

Thanks to the reversible flexibility of the tempflex temperature channel from hotset, cooling and heating channels in the molds can be freely laid out. Laying patterns close to the cavity with tight radii can be realized very easily.
