Problems solved by technology

[0003] At present, a single electroplating can no longer meet the requirements of customers. The current plastic products need to be electroplated with multiple metals at the same time to meet the needs of the product; but due to the respective characteristics of various metals, it is often difficult to electroplate several metals on the workpiece at the same time.

Embodiment 1

[0018] The continuous electroplating process comprises the following steps: (1) Ultrasonic degreasing: using alkaline solution, the composition is 3% of the sulfonate mass fraction of surfactant fatty acid methyl ester ethoxylate, 25% of sodium hydroxide, and the rest is water, The ultrasonic degreasing time is 4 minutes, and this step can realize the removal of grease on the surface of the piece to be plated; (2) electrolytic degreasing: the piece to be plated is used as the anode, and the stainless steel plate is used as the cathode, in a solution environment with a pH value of 12, through direct current , the current density is 10A / dm 2 , the solution temperature is 70°C, the solution composition is 3% of the sulfonate mass fraction of surfactant fatty acid methyl ester ethoxylate, 25% of sodium hydroxide, and the rest is water, and the electrolytic degreasing time is 4min. This step realizes further Remove the oily substance on the surface of the piece to be plated; (3) ac...

Embodiment 2

[0020] The continuous electroplating process comprises the following steps: (1) Ultrasonic degreasing: using alkaline solution, the composition is 1% of the sulfonate mass fraction of surfactant fatty acid methyl ester ethoxylate, 20% of sodium hydroxide, and the rest is water, Ultrasonic degreasing time is 3min, this step can realize the removal of surface grease to be plated; ultrasonic degreasing is carried out according to the following procedures: (A1) ultrasonic degreasing; (A2) industrial air knife treatment for 5min; (A3) immersion in 100% pure water for cleaning 6min, water temperature 50°C; ultrasonic degreasing process A1-A3 cycle 2 times to ensure thorough ultrasonic degreasing; (2) electrolytic degreasing: take the piece to be plated as the anode and the stainless steel plate as the cathode in a solution environment with a pH value of 8 In, through direct current, the current density is 5A / dm 2 , the solution temperature is 60°C, the solution composition is 1% of ...

Embodiment 3

[0022] The continuous electroplating process comprises the following steps: (1) Ultrasonic degreasing: using alkaline solution, the composition is 5% of the sulfonate mass fraction of surfactant fatty acid methyl ester ethoxylate, 30% of sodium hydroxide, and the rest is water, Ultrasonic degreasing time is 5min, this step can realize the removal of surface grease to be plated; ultrasonic degreasing is carried out according to the following procedures: (A1) ultrasonic degreasing; (A2) industrial air knife treatment for 10min; (A3) immersion in 100% pure water for cleaning 10min, water temperature 70°C; ultrasonic degreasing process A1-A3 cycle 3 times to ensure thorough ultrasonic degreasing; (2) electrolytic degreasing: take the piece to be plated as the anode and the stainless steel plate as the cathode in a solution environment with a pH value of 14 In, through direct current, the current density is 15A / dm 2 , the solution temperature is 80°C, the solution composition is 5%...

Abstract

The invention discloses a continuous electroplating process, which includes the following steps: (1) ultrasonic degreasing to realize the removal of grease on the surface of the piece to be plated; (2) electrolytic degreasing to realize further removal of oily substances on the surface of the piece to be plated; (3) ) acid activation, activate the surface of the piece to be plated, and improve the efficiency of subsequent electroplating; (4) nickel plating, realize fast nickel plating, can be used as primer nickel, and can also be used as golden nickel; (5) gold plating, realize fast gold plating; (6) ) tin plating to achieve fast and high-strength tin plating, especially after adding water-soluble fibers, the tin coating has better fastness; (7) ultrasonic hot water cleaning to clean the coating surface; The small holes are sealed to improve the anti-corrosion ability of the coating; (9) drying, and become the final product after drying; through continuous electroplating process, simultaneous electroplating of multiple metals is realized.

Description

technical field [0001] The invention relates to the field of electroplating, in particular to a continuous electroplating process. Background technique [0002] Electroplating products have the advantages of light weight, good corrosion resistance, easy molding and metal organic solvent resistance, light resistance, metallic luster, thermal conductivity, electrical conductivity, electromagnetic shielding, and easy welding. They are widely used in automobiles, motorcycles, hardware, etc. , electronics, communications and other industries are widely used. [0003] At present, single electroplating can no longer meet the requirements of customers. The current plastic products need to be electroplated with multiple metals at the same time to meet the needs of the product; however, due to the respective characteristics of various metals, it is often difficult to electroplate several metals on the workpiece at the same time. Contents of the invention [0004] The purpose of the...
