Smart Molding International 1-2022

24 molding technologies smart_molding international 1/2022 A mong the innovations that INCOE presented at Fakuma last year, the new "Heat- Inject" product stood out in that it uses the hot runner system as a carrier plat - form, but instead of melt, it brings heat into the cavity. The question following this concept "But why additional heat directly into the cavity?" is answered by Christian Striegel, Head of Develop - ment and Technical General Manager at INCOE International Europe: "This is not an additional heater, but a movable tempering stamp, whose heated tip in - troduces a heat pulse there by briefly pressing against the rear wall of the cavity." This short local impulse can contribute in many ways to optimiz - ing the quality of the molded part and the process, he says: weld lines and flow lines are still there, but no lon - ger visibly appear on the surface, matt points no longer appear in the area of the gate, areas with low wall thick - ness the cavity, such as in film hinges or thin-wall injection molding, can be flowed through more easily, and deli - cate geometries and microstructures are easier to manufacture. "This innovative temperature control technology, based on the patent-pend - ing Z-system from our partner Hotset, works extremely quickly with very low energy consumption. In doing so, it offers a technically relatively simple and robust solution for molded parts with visually demanding surfaces, such as panels for household appliances, consumer electronics, or instrument panels in vehicles," adds Frank Daniel, Commercial General Manager at INCOE International Europe. The idea of assembling "Heat-Inject" on hot runner systems has its origins in the concept of pre-assembled mod - ules. The idea here is to offer customers components for their injection molds that are already assembled into ready- to-use and ready-to-plug-in modules, thus saving effort and time during tun - ing and installation. "Of course, the tempering stamp needs to be spotted in order to cre - ate a suitable contact surface for op - timum heat transfer," explains general manager Frank Daniel. "But the fact INCOE International Europe has recently presented Direct-Flo™ hot runner systems with Heat-Inject, allowing for local "heat injections”. Part and process optimization with targeted heat pulses in the cavity INCOE: INjection COntrol Engineering Since 1958, this privately owned company has been a pioneer in the field of hot runner technology. We currently develop and produce hot runner systems on a worldwide basis for all areas of plastic injection molding. Our European subsidiary was founded in 1975. Our production plants in the USA, Brazil, Germany, Singapore, and China provide support for your business at a local level. Our service network covers more than 45 countries. It is made up of and managed by employees who feel at home with hot runner and injection molding technology. Injection molding markets around the world benefit from the wide variety of applications covered by our hot runner range. This variety facilitates technical solutions that meet the requirements of the various markets: automotive, transport, electronics, technical components, packaging, medicine, cosmetics, and household appliances.
