Problems solved by technology

[0003] Because the character requirements of light-transmitting keys are very precise, it is difficult to meet the quality standard with the current method. Not only is the yield rate extremely low, but many characters cannot be produced; moreover, such keys have poor wear resistance, anti-electromagnetic interference ability, and anti-static performance. Not good looking

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the embodiment of producing red transparent character electroplated pearl chrome buttons. The manufacturing process for producing red transparent character electroplated pearl chrome buttons includes the following steps:

[0010] 1. Material injection molding blank

[0011] The ABS material is used, and the transparent ABS material is injected into a button blank.

[0012] 2. Partial closed treatment

[0013] Apply commercially available 3364# insulating glue on the part of the blank that needs to be transparent or does not need electroplating, or paste it with insulating PVC tape for general electricians.

[0014] 3. Pre-plating treatment of blanks

[0015] (1) Stress relief: at normal temperature, soak in 25% volume of acetone solution for 30 minutes;

[0016] (2) Degreasing: at 40-50°C, add 1-3g / L surfactant, at a concentration of 20-50g / L sodium hydroxide or 20-50g / L sodium carbonate or 20...

Description

Technical field [0001] The invention relates to a manufacturing process of a translucent character electroplating button. Background technique [0002] At present, the method of making light-transmitting character electroplating buttons is to use ABS, PC, ABS+PC, epoxy resin and other non-conductive plastic materials to make characters through precision mold processing, and electroplating after injection molding. The electroplating process generally consists of the following 12 steps Step composition: 1. Material injection molding blank 2. Pre-plating treatment of the blank (including stress relief, degreasing, solvent swelling roughening, etc.); 3. Chemical roughening; 4. Neutralization, reduction or pickling; 5. Colloidal palladium sensitization and activation; 6. Degumming; 7. Electroless copper plating (or electroless nickel plating); 8. Drying; 9. Acid activation; 10. Plastic electroplating post-treatment process (including pre-plating copper, bright Various electropla...
