What are the methods for polishing plastic molds?

Plastic mold polishing includes: mechanical polishing, chemical polishing, electrolytic polishing, ultrasonic polishing, fluid polishing and magnetic abrasive polishing.

I. Mechanical polishing

Mechanical polishing generally uses oilstone strips, wool wheels, sandpaper, etc. Is a polishing method based on manual operation. A polishing method, which uses cutting and plastic deformation of the material surface to remove the polished surface to obtain a planar effect. One of the most commonly used polishing methods for optical lens molds.

Two. chemical polishing

The biggest advantage of chemical polishing is that it can polish complex workpieces without using complex equipment, and it can polish multiple workpieces at the same time with high efficiency. The most important material of chemical polishing is the cooperation of polishing solution, and finally the flat and smooth plane effect can be achieved.

Three. electropolishing

The principle of electrolytic polishing is the same as that of chemical polishing. Both sides rely on the selective dissolution of tiny protrusions on the surface of materials to make the surface smooth. Fahrenheit die steel is better than chemical polishing because it can eliminate the influence of cathode reaction and has a good effect. Generally, the electrolysis process is divided into two steps: macro leveling and micro anodic polarization.

Four. Ultrasonic polishing

Ultrasonic polishing is a way to put the workpiece into an ultrasonic field and polish the surface of the workpiece by using the oscillation of ultrasonic waves. The biggest disadvantage of ultrasonic polishing is that the tooling is difficult to manufacture and install, and the main advantage is that the macro force is small and the workpiece will not be deformed.

Verb (abbreviation for verb) fluid polishing

The commonly used methods of fluid polishing are: hydrodynamic grinding, abrasive jet machining and hydrodynamic grinding. The medium used is made of special compound with good fluidity and doped with low-pressure abrasive. It uses high-speed flowing liquid and abrasive particles to scour the surface of the workpiece to achieve the purpose of polishing.

The intransitive verb magnetic grinding and polishing.

The main advantages of magnetic grinding and polishing are high processing efficiency, good quality and good working conditions. It uses magnetic abrasive to work under the action of magnetic field to form a grinding brush to grind the workpiece.
