Embodiment Construction

[0019] Such as Figure 1-4 As shown, a flexible switch injection molding process includes the following steps: Step 1: Place the printed PET film in a knife die for punching, and place the positioning holes at both ends of the sheet in a 2 mm diameter hole during punching. Punching on the positioning hole of the knife die;

[0020] Step 2: Put the toasted rice in the storage barrel, and the baking parameters for the rice to be baked are 80°C, 2H;

[0021] Step 3: Set the parameters of the injection molding machine, place the punched PET panel diaphragm into the cavity of the front mold, and the front of the sheet is in contact with the cavity of the front mold;

[0022] Step 4: Combine the ITO film diaphragm and the PET diaphragm through injection molding to complete the production.

[0023] In the step 4, put the row of pins into the cavity of the rear mold of the mold, and finally carry out the mold-closing injection molding production, so that after injection molding, one...

Abstract

The invention discloses an injection molding process for a flexible switch. The injection molding process comprises the following steps that firstly, printed PET films are placed into a cutting die for punching, and during punching, positioning holes at the two ends of sheets are placed onto cutting die positioning holes with the diameter being 2 mm for punching; secondly, roasted plastic grains are placed into a storage barrel, wherein according to roasting parameters for roasting of the plastic grains, the roasting temperature is 80 DEG C, and the roasting time is 2 H; thirdly, parameters of an injection molding machine table are set, punched PET panel films are placed into a front die cavity, and the front faces of the sheets make contact with the front die cavity; and fourthly, ITO films and the PET films are integrated through injection molding, and production is completed. Under the working environment of an IMD product, a capacitive sensing function is achieved, and the application range of the product is widened; adhesive attaching is not needed, and integral forming is achieved; and the product is attractive and practical, and the sensing effect is excellent.

Description

technical field [0001] The invention relates to a molding process of a flexible switch. Background technique [0002] With the rapid development of electronic application technology, consumers' requirements for product interface and quality are also constantly improving. The fashionable appearance of the product and the sensitivity of the function have become the bargaining chip of the enterprise competition. As a new touch switch system, the capacitive switch meets the above requirements, and also improves the life and durability of the buttons, but the production cost of the product is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a flexible switch injection molding process. [0004] The technical scheme adopted in the present invention is: [0005] A flexible opening injection molding process, including the following steps: Step 1: Place the printed PET film in a die for punching, and place the positioning hole...
