Heitec now has developed a Multi Tip Edge Gate Hot Runner Nozzle which for the first time advantages of single nozzles and conventional Multi Tip Hot Runner Nozzles unite. The previous disadvantages do not exist any more.

The distinctive feature on the new Star Line Series (01.07) is that the Nozzle Tips are mounted into the Nozzle after the Nozzle Body is assembled in the Mold. This opens the possibility to gate into extreme positions on the plastic part. The molded parts are optically perfect since there is no parting line within the molding surface. The mold also can be made for less cost. The Nozzle opens new possibilities in mold and part design e.g. variable tip length within the same nozzle. Used in a Single Nozzle application the Mold can be made much smaller in size e.g. in a pitch circle of 42mm (1.653”) 4 cavities can be positioned; obviously these Nozzles can be used with Manifolds. The Nozzles depending on the design can gate between 1 and 8 Cavities at the time; thermocouple controlled by one control zone 220-240VAC. For small parts particularly in the field of Medical-, Cosmetic-, Electronic- and Packaging Industry are this Nozzle noteworthy and a less expensive option than using multiple single nozzles with manifolds.

Nozzle Tips are interchangeable with the mold mounted in the molding machine by the user and are available in various lengths. If needed, a cavity can be shut of by changing the length of the Tip. Due to the precise positioning of the Tip on the surface of the Plastic Part no cold slug is created and a clean break at the gate is given. The position of the gate can be placed as they would be placed using Tunnel Gates. Heitec has applied for a Patent on the Multi Tip Nozzle which can be used in all commodity Plastic Materials and has been proven to process PE, PP, PS, PC ABS and PA 6.6.
