Abstract

The invention discloses an in-mold forming touch control module comprising a perspective conductive carrier board and a molded shell body, a capacitive electrode layer which is a touch control sensing circuit made from indium tin oxide is arranged on one inner surface of the carrier board, the sensing circuit can be touched by one outer surface of the carrier board, and the shell body is coated and combined at the peripheral edges of the carrier board. The invention also comprises a production method of the in-mold forming touch control module, comprising the steps: the indium tin oxide is coated on the inner surface of the carrier board, the sensing circuit is formed by processing; the carrier board is arranged in a mold cavity, and molding material is injected in the mold cavity to form the molded shell body which is integratedly coated and combined at the peripheral edges of the carrier board, thereby improving the touch control sensitivity of the module and simplifying the process. The in-mold forming touch control module and the production method are conductive to the simple implementation in the environment of an injection molding machine which is provided with automatic loading and unloading devices and further conductive to enhancing the effectiveness of automatic production, compared with the prior art which adopts the layer iteration adhesion mode, the production method can effectively simplify the production process and reduce the working time and the cost.

Description

technical field [0001] The invention relates to an in-mold forming touch module and a production method thereof, in particular to a module technology for covering and combining a touch panel with a sensing circuit by using an in-mold injection molding technology. Background technique [0002] In Mold Touch (In Mold Touch) is derived from a combination of in-mold injection molding technology and touch panel manufacturing technology. [0003] Among them, in-mold injection molding technology has been widely used in the molding and processing of some plastic products in the factory. It must use a mold to inject molten plastic into the mold cavity with the contour shape of the object to be formed. , to make the shaped object. It is known that the more advanced in-mold technology now includes an In Mold Label (IML) technology, which can first implant a material to be bonded into the mold cavity, and then put the molten plastic Inject into the mold cavity, cover and combine the m...
