With the temperature control channels of the tempflex series, hotset expands the creative scope of designers in mold making.
Because thanks to the reversible flexibility of this corrugated hose solution made of stainless steel, the cooling and heating channels can be freely laid out in the cavities. In this way, it is very easy to realize near-contour laying patterns with tight radii. In addition, sophisticated deep drilling can often be dispensed with.
Tightly occupied interiors, faulty drilling or even overly ambitious time targets — such adversities are all too familiar to moldmakers in plastics and foundry technology. In such cases, the use of tempflex temperature control channels from hotset can prove to be a solution that is as user-friendly as it is cost-effective. This is a flexible corrugated hose product made of stainless steel that can be used for fast and simple realization of close-contour temperature control in the cavities. The moldmaker and his designer are thus given the opportunity to design even complex-structured channel layouts with small bending radii of just 10 mm without the need for complex deep drilling. “Our tempflex temperature control channels are simply fitted into previously milled grooves and connected to the media supply with the plug-in couplings of their ends. They can basically be used for cooling, preheating or heating molds in injection molding, extrusion, thermoforming and foundry applications,” 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 control channel 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 push-in couplings are either brass (metric) or stainless steel (imperial). With operating temperatures of up to 250° C, hotset’s flexible temperature control channel can be used for applications with both oil and water. “The tempflex is designed for a maximum pressure of up to 10 bar and is designed in such a way that only minimal pressure resistance emanates from it compared to the common 90° deflections — even with narrow installation radii,” emphasizes Bernward Seeberg.
Thanks to the reversible flexibility of the tempflex temperature control channel from hotset, cooling and heating channels can be freely laid out in the molds. Close contour laying patterns with tight radii can thus be realized very easily.
The tempflex temperature control channel from hotset is a flexible corrugated hose product made of stainless steel that can be used for the quick and easy realization of temperature control in molds.
Various problem solver
The development engineers at hotset have continued to refine and improve the tempflex, especially in the recent past, so that the adaptable corrugated hose product is now available to moldmakers as a problem solution for a wide variety of tasks. Since its use eliminates the need for expensive and time-consuming deep drilling, tempflex can also be used for rapid reworking or corrections to existing mold cavities. In this regard, it sometimes proves to be a cost-effective retrofitting tool for reviving older or discarded molds. “Even when subsequent optimizations to the temperature control system of a complex mold are pending, for example because its interior has become overbuilt in the meantime 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, the tempflex from hotset 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 replaced without the use of special tools. To match the tempflex, hotset’s range of accessories includes metric and imperial quick couplings for 1/4″ hoses with or without shut-off valves. On request, the customer can also obtain the tempflex in special lengths of more than 2,600 mm.
