TLDR
In this article, a distribution manifold assembly for carrying a fluid includes a manifold body having at least one fluid channel running therethrough, and at least 1 infrared radiation source dimensioned and disposed to apply infrared radiation to the external surface of the manifold body.Abstract:
A distribution manifold assembly for carrying a fluid includes a manifold body having at least one fluid channel running therethrough, and at least one infrared radiation source dimensioned and disposed to apply infrared radiation to the external surface of the manifold body. If desired, a control means controls the application of infrared radiation by within the fluid channel remains substantially constant. An insulation layer can surround at least a portion of the manifold body, and this insulation layer is disposed so as not to obstruct completely the infrared radiation source. In a second embodiment, the manifold assembly has a primary manifold body having at least one fluid channel running therethrough, and first and second surfaces so that there are first and second elongate hollows. First and second infrared radiation sources are contained within the elongate hollows. A method of heating a fluid distribution manifold having an internal fluid channel is also provided.read more

Assembly of injection molding manifold, nozzles and mold
TL;DR: In this article, a heated manifold is used for the distribution of heated plastic resins to the various cavities of injection molds for thermoplastic materials, with a removable tip which can be adjusted to change the overall length of the bushing.
Patent
Method and apparatus for controlling injection molding
TL;DR: In this article, a response model of a variation in mold temperature in the injection mold is proposed, and a parameter (time constant) of the response model is decided using these measured values, and if the molding cycle is changed or the measured mold temperature develops a difference with respect to a standard mold temperature, a target value of coolant temperature is calculated in such a manner that the mold temperature at the start of injection will be held constant at all times, and control of the cooling channel is carried out using this target cooling channel.
