Types Of Plastic Injection Mold Polishing

Introduction to the plastic injection mold polishing

These days, industrial products are developing in the direction of product high quality as well as product diversification, in this way mold quality is going to have an influence on product quality directly, so improving mold quality has become an important task. Plasticinjection moldingpolishing is a technology that helps to obtain a smooth mold surface. It is very different from the surface treatment of other industries. It has higher standards for polishing process, smoothness, and geometric accuracy.

Types of plastic injection mold polishing service

(1) Mechanical polishing

Mechanical polishing is a method of removing the protruding part on the workpiece surface by cutting or plastic deformation on the surface of the material to obtain a smooth surface. Whetstone, wool wheel, and sandpaper are usually used for manual operation; if the surface quality is high, the processes of ultra-precision grinding and polishing should be used. This technology can reach a surface roughness of Ra0.008 μm, which represents the best value for mold polishing.

(2) Chemical polishing

Chemical polishing refers to the plastic injection mold polishing process of immersing a material in a chemical medium to ensure the micro-protrusions on the surface of the material dissolve before the dents to obtain a smooth surface. The method can be used to polish workpieces with complex shapes and can polish multiple workpieces at the same time, with high efficiency. The surface roughness that can be obtained by chemical polishing is usually Ra 10 μm.

(3) Electrolytic polishing

The basic principle of electrolytic polishing is the same as that of chemical polishing, which is to selectively dissolve the surface of the material to form a smooth surface. Compared with chemical polishing, it can eliminate the influence of the cathode reaction to produce a more significant effect.

(4) Ultrasonic polishing

Ultrasonic polishing is a method that uses ultrasonic vibration of the tool part and uses abrasive suspension to polish brittle hard materials. The workpiece is immersed in the abrasive suspension, and then placed in an ultrasonic field together with the suspension, and the surface of the workpiece is ground and polished by the action of ultrasonic waves. Ultrasonic machining has a small macroscopic force, so it will not cause the deformation of the workpiece.

(5) Fluid polishing

Fluid polishing relies on the flowing liquid and the abrasive particles it carries to erode the surface of the workpiece to achieve the purpose of polishing. Hydrodynamic grinding is driven by hydraulic pressure, the polymer in the medium flows at low pressure, and the abrasive particles are usually silicon carbide powder.

(6) Magnetic grinding and polishing

Magnetic grinding and polishing of plastic molding china refer to the use of magnetic abrasives to form a brush under the action of a magnetic field to grind the workpiece. The method has high processing efficiency, good quality, and easy control of processing conditions. The surface roughness obtained by this method can reach Ra0.1 μm.
