INS (Film Insert Molding) technology

Abstract

The invention discloses an INS (Film Insert Molding) technology, which comprises a step S1: after blister forming is carried out, setting a membrane shell detection step. The S1 comprises the following steps of: S1.1: inputting planned coordinate values of a plurality of appointed positions of the membrane shell into a profile tolerance detector, and taking as a standard value; S1.2: putting a membrane shell to be detected in the profile tolerance detector, and carrying out fixation; S1.3: measuring the plurality of appointed positions of the membrane shell by the profile tolerance detector, comparing the coordinate values of a plurality of detected appointed points with a standard value, and displaying the deviation values of the point values of a plurality of points on a display screen;and S1.4: regulating a corresponding membrane shell blister mould with an overlarge deviation value. The invention provides the INS technology, a difference value between the thickness of each position of the blister membrane shell and the thickness of each position of the standard membrane shell is detected through the profile tolerance detector, the difference value is fed back to the blister mould to regulate the blister mould, the blister mould is repeatedly corrected to guarantee a percent of pass of the membrane shell, and the percent of pass of injection is guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to an INS process. Background technique [0002] The INS process of the car refers to pre-absorbing the INS film with appearance effect, punching the excess film edge, and then placing the die-cut film shell in the injection mold for injection molding. The process is: film heating - blister forming - die cutting - the formed film shell is placed in the cavity - mold closing, injection molding - mold opening. [0003] The quality of the membrane shell after blister molding often determines whether the quality of the membrane shell after injection molding is qualified. However, the traditional INS process has no corresponding quality inspection equipment and means of adjusting the contour of the membrane shell after the membrane shell is blister formed, so it cannot control the quality of the membrane shell. The pass rate of the shell often leads to the scrapping of ...

[0003] The quality of the membrane shell after blister molding often determines whether the quality of the membrane shell after injection molding is qualified. However, the traditional INS process has no corresponding quality inspection equipment and means of adjusting the contour of the membrane shell after the membrane shell is blister formed, so it cannot control the quality of the membrane shell. The pass rate of the shell often leads to the scrapping of many membrane shells, and the industry needs to know whether the membrane shells are available after injection molding is done. This makes it impossible to immediately check the quality of the membrane shells, which will not only waste the operation of the subsequent process , at the same time it will greatly increase the cost and cause waste
