With less energy to higher injection molding quality

K trade fair from 19 - 26 October 2022 in Dusseldorf
K trade fair 2022, from 19 — 26 Oc­to­ber. hotset ex­hi­bi­tion stand in Hall 1 Stand A20. 
In ad­di­tion to ex­pand­ing its range of tem­per­a­ture sen­sors and heat­ing el­e­ments, hotset is push­ing ahead with the de­vel­op­ment of pi­o­neer­ing sys­tem prod­ucts for use in plas­tics and flu­id tech­nol­o­gy. As con­crete ex­am­ples, the com­pa­ny will be show­cas­ing the lat­est ver­sions of its DH-Sys­tem for dy­nam­ic tem­per­a­ture con­trol of in­jec­tion molds and its D‑System for in-situ mea­sure­ment of ther­mo­hy­draulic process­es in liq­uids at tem­per­a­tures of up to 180°C at K in Düs­sel­dorf (Oct. 19–26, 2022). Both so­lu­tions pro­mote the re­al­iza­tion of qual­i­ty-en­hanc­ing, sus­tain­able and en­er­gy-sav­ing processes. 
Compared with the variothermal method, hotset's DH-System is more effective and energy-saving. It acts with a very fast heating rate of up to 60 Kelvin per second, has a very targeted effect only on a minimal mass and uses 50 times less energy in the heating phase.
Com­pared with the var­io­ther­mal method, the DH-Sys­tem from hotset is more ef­fec­tive and saves more en­er­gy. It acts with a very fast heat­ing rate of up to 60 Kelvin per sec­ond, has a very tar­get­ed ef­fect on­ly on a min­i­mum mass and us­es 50 times less en­er­gy in the heat­ing phase. 
How can qual­i­ty im­prove­ments, re­source con­ser­va­tion and en­er­gy ef­fi­cien­cy be brought down to a com­mon de­nom­i­na­tor? Mold mak­ers in in­jec­tion mold­ing tech­nol­o­gy and pro­fes­sion­als in flu­id tech­nol­o­gy who are in­ves­ti­gat­ing this ques­tion will find an­swers at this year’s K at booth A20 in Hall 1. hotset, al­so known as a man­u­fac­tur­er of­Be­cause here,  heat­ing el­e­ments and tem­per­a­ture sen­sors – show­cas­es two tech­nol­o­gy in­no­va­tions,  that cov­er all three as­pects. These are the lat­est ver­sions of the Dy­nam­ic Heat sys­tem (for­mer­ly Z‑System) for dy­nam­ic tem­per­a­ture con­trol of in­jec­tion molds and the D‑System for in­stant analy­sis of ther­mo­hy­draulic process­es in flu­id cir­cuits. “At K, we will not on­ly present the func­tion of these tech­nol­o­gy so­lu­tions, but will al­so use spe­cif­ic ex­am­ples to il­lus­trate how they can be used to es­tab­lish both qual­i­ty-en­hanc­ing and en­er­gy-sav­ing process­es in in­jec­tion mold­ing tech­nol­o­gy”, says hotset Sales Man­ag­er and au­tho­rized sig­na­to­ry Sven Braatz.

The DH-Sys­tem from hotset is con­fig­ured to cus­tomer spec­i­fi­ca­tions and pro­vid­ed as a com­plete so­lu­tion ready for use. The pic­ture shows the tem­per­a­ture con­trol head with fin, heat­ing el­e­ment and in­te­grat­ed tem­per­a­ture sensor. 

Internationally on the road to success

With the DH sys­tem, hotset of­fers mold mak­ers in in­jec­tion mold­ing tech­nol­o­gy a high-speed process for par­tial-cy­cle tem­per­a­ture con­trol, which on the one hand avoids vi­su­al de­fects (vis­i­ble weld lines, dull ha­los, etc.), but on the oth­er hand al­lows fil­i­gree fine struc­tures and very thin wall thick­ness­es to be re­al­ized. Syn­chro­nized with the in­jec­tion mold­ing process, the cav­i­ties can thus be heat­ed and cooled se­lec­tive­ly or in sec­tions at a rapid heat­ing rate of up to 60 K/s – en­abling very fast tem­per­a­ture changes in short cy­cles. Man­u­fac­tur­ers of in­jec­tion mold­ed parts for the con­sumer and au­to­mo­tive in­dus­tries can thus im­prove the sur­face qual­i­ty of their prod­ucts and open up new prospects for light­weight con­struc­tion and minia­tur­iza­tion. In ad­di­tion to renowned ma­chine man­u­fac­tur­ers in the in­jec­tion mold­ing in­dus­try, INCOE has now al­so in­te­grat­ed the con­cept of par­tial tem­per­a­ture con­trol in­to its port­fo­lio. “We are mak­ing this strate­gic part­ner­ship with one of the lead­ing hot run­ner man­u­fac­tur­ers pub­lic for the first time at K.” The com­pa­ny of­fers the DH sys­tem – slight­ly mod­i­fied – un­der the name Heat-In­ject, us­ing its hot run­ner tech­nol­o­gy as a plat­form for in­te­gra­tion in­to the in­jec­tion mold “In this way, us­ing both sales net­works, we can fur­ther es­tab­lish our ex­per­tise in tem­per­a­ture con­trol tech­nol­o­gy in the mar­ket”, ex­plains Sven Braatz. In ad­di­tion, hotset will demon­strate at its booth on a run­ning in­jec­tion mold­ing ma­chine with a sam­ple mold that the per­for­mance of its sys­tem so­lu­tion ex­tends far be­yond the lim­its of var­io­ther­mal tem­per­a­ture con­trol. “The DH-Sys­tem acts faster, more ac­cu­rate­ly and more eco­nom­i­cal­ly. Whether heat­ing rate, en­er­gy con­sump­tion, per­for­mance, cy­cle time or safe­ty – it is ahead every­where. Com­pared to the var­io­ther­mic method, it is much more pro­duc­tive, eco­nom­i­cal and sus­tain­able. It us­es 50 times less en­er­gy in the heat­ing phase alone”, em­pha­sizes Sven Braatz.

With its mo­bile D‑System (HT), hotset of­fers a flex­i­ble and easy-to-use mea­sur­ing de­vice for in-situ analy­sis of the en­er­gy bal­ance of wa­ter cy­cles in in­jec­tion molds. 

Premiere: New measuring module for up to 180 °C

The sec­ond trade fair high­light from hotset, the D‑System for mon­i­tor­ing ther­mo­hy­draulic events in me­dia cir­cuits, al­so serves both qual­i­ty as­sur­ance and the im­ple­men­ta­tion of sus­tain­abil­i­ty cri­te­ria. It will be pre­sent­ed at K in the stan­dard ver­sion for mea­sur­ing flu­ids with tem­per­a­tures of up to 85°C and, for the first time, in the new HT ver­sion for mon­i­tor­ing flu­ids with tem­per­a­tures of up to 180°C. Both ver­sions are mo­bile and pro­vide in­jec­tion mold­ers with all the da­ta they need to eval­u­ate their wa­ter cir­cuits – and, based on this, en­able op­ti­miza­tion of tem­per­a­ture con­trol in terms of en­er­gy and flu­id tech­nol­o­gy. The D‑System records the flow­ing wa­ter vol­ume, the sup­ply and re­turn tem­per­a­ture ∆T as well as the sup­ply and re­turn pres­sure ∆P – and pro­vides in­for­ma­tion on how much en­er­gy is with­drawn from or added to the wa­ter cir­cuit dur­ing op­er­a­tion. “In the new HT ver­sion, the sys­tem is al­so suit­able for high-tem­per­a­ture ap­pli­ca­tions such as are typ­i­cal in the pro­duc­tion of ther­mo­plas­tic mold­ed parts with high­er op­ti­cal re­quire­ments”, adds Sven Braatz. In some places, the D‑System from hotset is al­so part of the equip­ment of mo­bile ser­vice teams or it serves as a qual­i­ty as­sur­ance tool for sam­pling pi­lot and pre-se­ries. Some in­jec­tion mold­ers pro­duc­ing for med­ical tech­nol­o­gy are now us­ing it for prod­uct validation.

Sven Braatz: “Our DH-Sys­tem is faster, more pre­cise and more ef­fi­cient than var­io­ther­mal tem­per­a­ture con­trol. Whether it’s the heat­ing rate, en­er­gy de­mand, per­for­mance, cy­cle time or safe­ty – it’s ahead everywhere.” 

Forward-looking solutions

With both tech­nol­o­gy so­lu­tions pre­sent­ed at K, hotset is push­ing the bound­aries of what was pre­vi­ous­ly pos­si­ble. While the DH-Sys­tem is con­sid­ered a pi­o­neer of a new gen­er­a­tion of flex­i­ble, re­source-sav­ing in­jec­tion mold­ing tem­per­a­ture con­trol sys­tems and leads to sig­nif­i­cant qual­i­ty im­prove­ments in mold­ed part pro­duc­tion, the D‑System (HT) opens up new per­spec­tives not on­ly for mold­mak­ing. “We con­sid­er it our task and re­spon­si­bil­i­ty to make our cus­tomers’ process­es more en­er­gy-ef­fi­cient and sus­tain­ably more ef­fec­tive”, says Sven Braatz.
