High-precision injection molding molds are widely used.
Car rearview mirror is an important safety part, its mirror car accessories car rearview mirror surface, shape and manipulation are quite particular. The quality and installation of rear-view mirrors have corresponding industry standards and cannot be arbitrary.
Nowadays, the application of two-color plastic injection molding molds has become more and more extensive, and even many industries with extremely high product size requirements have begun to use injection molding parts, which puts forward higher precision requirements for injection molding processing.
To achieve high-precision injection molding, it is natural to use high-precision injection molding molds. So what are the salient features of high-precision injection molding molds?
1. Good molding and coloring properties.
2. Strong bonding ability.
3. The two-color plastic mold processed by precision injection molding has good wear resistance and self-lubrication:
The plastic has a small friction coefficient, good wear resistance, good self-lubrication, and high specific strength and low transmission noise. It can work effectively in liquid media, semi-dry or even dry friction conditions. It can be made into machine parts such as bearings, gears, cams and pulleys, and is very suitable for occasions where the speed is not high and the load is not large.
4. Good chemical stability of precision injection molding molds: most plastics have good resistance to acid, alkali, salt, water and gas, and they do not chemically react with these substances under normal conditions.
5. The two-color plastic mold processed by precision injection molding has good electrical insulation, heat insulation and sound insulation performance.
6. High specific strength and specific stiffness: the absolute strength of plastic is not as high as that of metal but the plastic density is small, so the specific strength (σb/ρ) and specific stiffness (E/ρ) are quite high. In particular, reinforced plastics made of various high-strength fibrous, flake and powdered metals or non-metals as fillers have higher specific strength and specific stiffness than metals.
7. The density of the two-color plastic mold processed by precision injection molding is small: the plastic density is small, which is of great significance for reducing the weight of mechanical equipment and saving energy, especially for vehicles, ships, aircraft, and spacecraft.
