Even surface temperature control in foil technology

P‑System heating plates

With the sur­face heat­ing plates of our P‑System, we of­fer you an in­no­v­a­tive sys­tem so­lu­tion for the process-re­li­able gen­er­a­tion of uni­form and ho­mo­ge­neous sur­face tem­per­a­ture con­trol dur­ing the pro­cess­ing of a wide va­ri­ety of ma­te­ri­als. Par­tic­u­lar­ly in film tech­nol­o­gy, the use of our heat­ing plates of­fers nu­mer­ous ad­van­tages over stan­dard so­lu­tions for sur­face tem­per­a­ture control. 

Heating plates in foil technology

The as­pect of pre­cise sur­face tem­per­a­ture con­trol plays a cen­tral role in many film tech­nol­o­gy process­es. Gen­er­at­ing uni­form and ho­mo­ge­neous tem­per­a­ture fields over large ar­eas is par­tic­u­lar­ly de­mand­ing in terms of process tech­nol­o­gy. This is im­por­tant, for ex­am­ple, in the ther­mo­form­ing of food pack­ag­ing, in the pro­cess­ing of shrink and stretch films, or in film weld­ing. Our heat­ing plate of­fers an ide­al so­lu­tion for this task. 

P‑System heating plates for optimum surface temperature control

Do you want to cre­ate con­ver­gent and ho­mo­ge­neous sur­face tem­per­a­ture con­trol over large ar­eas of plas­tic films in film tech­nol­o­gy — for ex­am­ple, when ther­mo­form­ing or ther­mo­form­ing blis­ter packs and plas­tic trays? For plas­tics, are you look­ing for a way to achieve uni­form sur­face tem­per­a­ture con­trol of pack­ag­ing films, such as tubu­lar , shrink or stretch films? Do you need a process-re­li­able and pre­cise­ly con­trol­lable sur­face tem­per­a­ture con­trol sys­tem for film seal­ing, hot press­ing, seal­ing or vac­u­um­ing? The so­lu­tion for all these tasks is our ver­sa­tile heat­ing plate for sur­face heat­ing of plas­tic films and many oth­er materials! 
  • High­ly ac­cu­rate: Grad­ual tem­per­a­ture de­vi­a­tions of on­ly 2 °C en­sure ho­mo­ge­neous tem­per­a­ture dis­tri­b­u­tion over the en­tire area cov­ered by the heat­ing plate and thus op­ti­mum sur­face tem­per­a­ture control
  • Com­plete so­lu­tion: Ready-to-mount heat­ing plate in­clud­ing con­nec­tion and fas­ten­ing tech­nol­o­gy for easy in­te­gra­tion in­to ma­chines, sys­tems and equip­ment for ther­mo­form­ing, deep draw­ing, film weld­ing, hot press­ing, etc.
  • In­di­vid­ual: Cus­tomer- and project-spe­cif­ic di­men­sion­ing, de­sign, coat­ing and con­fig­u­ra­tion of all sys­tem components
  • Flex­i­ble: sup­ply volt­ages from 12 to 400 volts and pow­er den­si­ties of up to 15 W/cm²

Higher process reliability for film technology

With the sur­face heat­ing pan­els of our P‑System, we of­fer you an in­no­v­a­tive sys­tem so­lu­tion for the process-safe gen­er­a­tion of a uni­form and ho­mo­ge­neous sur­face tem­per­a­ture con­trol dur­ing the pro­cess­ing of, among oth­er things, plas­tics used in ther­mo­form­ing, ther­mo­form­ing, film weld­ing, hot press­ing, etc. The de­ci­sive fac­tor here is that the tem­per­a­ture val­ues of the film heat­ed with a P‑System sur­face heat­ing plate from hotset var­ied on­ly min­i­mal­ly through­out the en­tire tem­per­a­ture con­trol field; max­i­mum de­vi­a­tions of no more than 2 °C are char­ac­ter­is­tic. This gives you an ex­treme­ly pre­cise and process-re­li­able sys­tem that sup­ports the pro­duc­tion of high-qual­i­ty film prod­ucts for pack­ag­ing tech­nol­o­gy. P‑System sur­face heat­ing plates from hotset are al­ways ready-to-in­stall com­plete so­lu­tions whose de­sign and ther­mo­dy­nam­ic con­fig­u­ra­tion are op­ti­mal­ly adapt­ed to the in­di­vid­ual re­quire­ments of ma­chine and plant man­u­fac­tur­ers in the var­i­ous ar­eas of film tech­nol­o­gy. Whether for ther­mo­form­ing blis­ter packs or plas­tic pal­lets, for film seal­ing tubu­lar bags or many oth­er tasks — the heat­ing plate sys­tem can be pre­cise­ly adapt­ed to any sur­face tem­per­a­ture con­trol situation. 

The most important questions for the design of a heating plate

The fol­low­ing 6 ques­tions are relevant:

  • What is heat­ed in the process?
  • What tem­per­a­ture should be supplied?
  • What kind of tem­per­a­ture fluc­tu­a­tions are tolerable?
  • In what kind of time pe­ri­od should the heat­ing take place?
  • What spe­cif­ic lo­ca­tion is to be heated?
  • What are the am­bi­ent conditions?

Structure of a heating plate for the foil technique

Struc­ture details

Foil technology: Thinner, lighter, more accurate

The ho­mo­ge­neous sur­face tem­per­a­ture con­trol of the P‑System pan­el heat­ing plate pro­duces very uni­form film wall thick­ness­es, which re­duces weight dif­fer­ences on the end prod­uct to a min­i­mum. In ad­di­tion, thin­ner films can be used — for ex­am­ple in ther­mo­form­ing — which con­serves re­sources, and un­wel­come streaks in the pack­ag­ing ma­te­r­i­al can al­so be avoid­ed. An­oth­er plus point when pro­cess­ing in film tech­nol­o­gy: dam­age to sen­si­tive func­tion­al lay­ers can be avoid­ed with the use of an ap­pro­pri­ate P‑System heat­ing plate. The ad­van­tages of P‑System sur­face heat­ing plates in terms of the qual­i­ty of the end prod­ucts can al­so be quan­ti­fied in con­crete fig­ures. Prac­ti­cal se­ries of mea­sure­ments all led to the re­sult that the tem­per­a­ture val­ues of the film heat­ed with such a sur­face heat­ing plate from hotset fluc­tu­ate on­ly min­i­mal­ly in the en­tire tem­per­ing field. Char­ac­ter­is­tic are punc­tu­al de­vi­a­tions on the foil of at most 2 °C! In con­trast, the sur­face tem­per­a­ture dif­fer­ences of con­ven­tion­al stan­dard heat­ing pan­els reach up to 15 °C. For all those equip­ment and plant man­u­fac­tur­ers for whom pre­cise and ho­mo­ge­neous sur­face tem­per­a­ture con­trol rep­re­sents a de­ci­sive process stage in their tech­ni­cal process­es (e.g. ther­mo­form­ing, deep draw­ing, film weld­ing and hot press­ing), this heat­ing plate is vir­tu­al­ly an ide­al solution. 

Surface temperature control individualized at all levels

The P-System is used for thermoforming or thermoforming of blister packs and plastic trays
The pos­si­bil­i­ties for cus­tomer and project-spe­cif­ic cus­tomiza­tion of our P Sys­tem sur­face heat­ing pan­els ex­tend across all com­po­nents and lev­els. The de­sign of the heat trans­fer plate, the se­lec­tion of the heat­ing el­e­ment (hot­flex flex­i­ble tubu­lar heater, hot­form sil­i­cone heat­ing el­e­ment, etc.), the ma­te­r­i­al of the in­su­lat­ing plate or the ques­tion of whether an in­stal­la­tion space in­ter­me­di­ate plate is re­quired — every­thing is de­signed for your spe­cif­ic ap­pli­ca­tion from the foil tech­nol­o­gy or oth­er ar­eas. This al­so ap­plies to the de­sign of the cov­er plate with the plug-in con­tacts and fas­ten­ing el­e­ments for in­stal­la­tion in your ther­mo­form­ing line, your blis­ter or vac­u­um ma­chine, your film seal­ing de­vice, and, and, and. Even when it comes to de­sign­ing the sur­faces of the heat trans­fer plate, we of­fer you a wide range of op­tions: Func­tion­al coat­ings with an­ti­sta­t­ic , non-stick and asep­tic prop­er­ties can be re­al­ized as well as sur­faces with in­creased wear , abra­sion and cor­ro­sion pro­tec­tion. The hot plat­en is de­signed com­plete­ly ac­cord­ing to your re­quire­ments for ther­mo­form­ing, deep draw­ing, film weld­ing, hot press­ing, and so on. What is clear to us is that ther­mo­form­ing of plas­tics, such as for blis­ter packs or plas­tic trays, places dif­fer­ent de­mands on the ther­mo­dy­nam­ics of hot platens than does the weld­ing of tubu­lar bag films. Fur­ther­more, tem­per­a­ture sen­sors can al­so be in­te­grat­ed to pro­tect against ex­cess tem­per­a­tures. We are al­so able to take in­to ac­count spe­cial re­quire­ments for slid­ing prop­er­ties, sur­face hard­ness, chem­i­cal re­sis­tance, elec­tri­cal con­duc­tiv­i­ty and ease of clean­ing. And if re­quired, we can al­so struc­ture and con­tour the sur­faces of our P Sys­tem sur­face heat­ing panels. 

Heating plates for thermoforming plastics

De­tails about hot plates for thermoforming

Our heat­ing plates, which are de­signed for ther­mo­form­ing, are in­stalled in ma­chines. They heat the rigid film drawn from large rolls to make it soft and formable. This process is al­so known as ther­mo­form­ing. The uni­form­ly heat­ed film can now be pressed in­to any shape, so that af­ter cool­ing, it re­tains this shape per­ma­nent­ly. This pro­duc­tion process is used to cre­ate pack­ag­ing for cheese and sausage or blis­ter pack­ag­ing for elec­tri­cal appliances.

Heating plates for film welding

Our heat­ing plates, which are de­signed for film weld­ing, are used in var­i­ous de­vices. They heat the two foils that are be­ing weld­ed to the de­sired tem­per­a­ture. With a me­chan­i­cal pres­sure the heat­ed foils are pressed to­geth­er. Af­ter cool­ing, they are per­ma­nent­ly joined, pro­vid­ing a sta­ble clo­sure of bags as well as films.

Heating plates for hot pressing
