Therefore, the patent publication No. 1252150 proposes a process for in-film decorative injection molding, which can form a patterned film directly on a plastic substrate by using a mask, thereby avoiding costly use of a photoresist and a surname and The removal of chemicals such as photoresist can also effectively avoid the problem that the process will leave the metal oxide layer on the plastic substrate. Nowadays, the infrared transceivers of remote controls and monitors, mobile phones and computers need to be installed - the filter plate is in front of the receiving component, and the dimming plate can pass infrared rays above the infrared wavelength range, and can block lower than near infrared rays. Visible light and ultraviolet light in the wavelength range. Conventionally, the filter of the infrared ray-receiving element is manufactured using dyed plastic, which is molded into a single component via plastic injection, and then a plurality of single components are combined as required. This process lacks autonomy and variability. Therefore, there is a need for a filter plate in which an infrared ray receiving member is fabricated by using a film. A. SUMMARY OF THE INVENTION The object of the present invention is to provide a one-step forming process for combining plastic injection molding and printing infrared ink hardening film, and the filter plate of the infrared receiving component can be obtained by using general plastic with infrared light transmissive ink, without being subject to dyeing.
