Temps de cycle (production) -- RéductionIndex. décimale : 668.4 Plastiques, vinyles Résumé : The new injection-molding machine Engel duo speed combines productivity and efficiency with short cycle times in a high clamping force range. The two-platen machine is thus making inroads into a range of packaging applications that were formerly the domain of toggle machines. Available with clamping forces from 4000 to 11,000 kN, the new large machine type is mainly targeted at manufacturers of pails as well as storage and transport containers. Note de contenu : - Over 25 years of experience with two platens
- Predictive movement sequences shorten the cycle
- Smart pump control improves energy efficiency
- Unlimited possibilities also at the injection unit
- Larger opening strokes create more freedom
- Equipped for recyclates
- Figure : If you want a somewhat larger sized pail: the duo speed large machine was developed specifically for manufacturing pails and transport boxes
- Fig. 1 : The new duo speed is tailored for packaging and logistics applications, based on over 25 years’ experience with large two-platen machines. Over 10,000 injection-molding machines of the duo series are in use around the world
- Fig. 2 : Due to the overlapping of machine movements, the dry cycle time is reduced by up to 25 % depending on machine size

MécatroniqueLa mécatronique est la combinaison synergique et systémique de la mécanique, de l'électronique, de l'automatisme et de l'informatique en temps réel. L'intérêt de ce domaine d'ingénierie interdisciplinaire est de concevoir des systèmes automatiques puissants et de permettre le contrôle de systèmes complexes.
La norme NF E 01-010 (2008) définit la mécatronique comme une «démarche visant l’intégration en synergie de la mécanique, l’électronique, l’automatique et l’informatique dans la conception et la fabrication d’un produit en vue d’augmenter et/ou d’optimiser sa fonctionnalité».
Temps de cycle (production) -- RéductionIndex. décimale : 668.4 Plastiques, vinyles Résumé : Cycle times of three to four seconds have long been part of everyday life in the injection molding of packaging parts. And the pressure to speed up production rhythms continues to increase. Shaving just one tenth of a second shorter off the cycle time is enough to increase output by three per cent. An assistance system from Engel is capable of doing precisely that, boosting the productivity of high-performance injection molding even further. Note de contenu : - Mold movement takes up a large share of cycle time
- Precision coordination of mold movement with the process is the key
- Focus on mechatronic drive system
- Fire-tuning for each individual application
- Producing thin-wall containers five percent faster
- Standard feature in high-performance machines
- Fig. 1 : iQ motion control shortens mold opening and closing on toggle machines. This leads to shorter dry cycle times
- Fig. 2 : During mold closing and subsequent dynamic buildup of clamping force, the drive is constantly cycling between acceleration and deceleration
- Fig. 3 : The variable transmission ratio of the toggle ensures high mold speeds during long opening strokes (toggle retracted) and high power transmission from motor to mold under clamping force (toggle extended)
- Fig. 4 : The speed of the closing motor (left) and the drive torque (right) clearly reveal where time is saved in the cycle. The yellow curve shows the behavior obtained with active iQ motion control. Green shows the reference curve without iQ motion controlEn ligne : https://drive.google.com/file/d/13ni4fjcwbO3JMivq8ilcBDmf-B4E5l35/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=39752

Temps de cycle (production) -- RéductionIndex. décimale : 668.4 Plastiques, vinyles Résumé : During thermoforming, films need to be heated as quickly as possible, both in defined areas and across the entire surface. Frimo has developed a new film heating process, called Time Shifted Heat Control, specifically for this reason. The key to heating the film using halogen infrared emitters is a specially-developed calculation algorithm. Note de contenu : - Complete film heating system
- Lower space requirements and higher flexibility
- Energy saving and shorter cycle times
- The time shifted heat control heating system consists of halogen infrared emitters, which operate efficiently by using an individualized calculation algorithm. The individual emmitters can be changed out quickly without an electrician
- Fig. 1 : Thermoforming machine with heater bank upgraded to TSHC
- Fig. 2 : The operator can input the surface temperature that must be reached in degrees Celsius rather than the typical percentage of maximum output
- Fig. 3 : Emmiter activation sequence after 1s, 3s and 4.5s. The clamp frame influences the film perimeter heating. The halogen infrared emitters on the edges are therefore switched on earlier than those in the middle
