Electroless nickel plating, Steel material cutting, Laser welding processing, Synthetic rubber molding and assembly

Focus on Electroless Nickel Plating


Various metals can be plated, and the plating film has a consistent thickness that is easy to control. It provides excellent adhesion, hardness, wear resistance, and corrosion resistance.

Production for Extra-Length Materials

Can accommodate cutting up to a length of 2100 mm.

 

 

1.

Hanging of fixtures for shafts(Racking)

Prevents shafts from colliding and causing scratches. Light components and small pins are placed on the grid of the hanging rack.

2.

Solvent Cleaning

Oil Removal Before Metal Plating

※The main cause of poor adhesion in metal plating is incomplete surface preparation before plating. After the oil removal process, a water rinse is performed to remove chemicals. If water droplets are found on the product, indicating incomplete oil removal, the process will be revisited to ensure complete oil removal.

3.

Ultrasonic cleaning

Using an Ultrasonic Cleaning Machine (This cleaning method uses ultrasonic waves to generate bubbles in the liquid, and the impact from the collapsing bubbles is used for cleaning).

4.

Acid dipping cleaning

Stimulating the material's activity to enhance metal coating adhesion. It also removes rust and the film formed from heat treatment on the material's surface, using hydrochloric acid or sulfuric acid depending on the type of material.

5.

Ultrasonic cleaning

Using an ultrasonic cleaning machine (a cleaning method that uses ultrasonic waves to generate bubbles in a liquid, and utilizes the shock waves from the collapsing bubbles to clean).

6.

Electro cleaning

Removing fine abrasive residues, such as polishing marks that cannot be removed by the acid immersion process.

7.

EN Plating

The plating time is determined by the desired thickness of the film.

8.

Water washing

Carry out each process as necessary.

9.

Treatment with corrosion prevention process

Process that forms an oxidation film by force (corrosion prevention process).

10.

Hot Dipping Cleaning

​​

Final rinse with warm water.

11.

Drying

Dry

12.

Chemical control

We record and manage the concentration, pH value, plating temperature (temperature during analysis and temperature in the tank), and use the most suitable plating solution.

 

Pure water production equipment

Pure water is produced within the company, and waste is collected and disposed of by a government-approved waste disposal service provider.
