Great flexibility during installation

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.
