Release Time : 2025-03-13
Machined plastic parts are widely used in electronic devices and play an important role in improving the durability of electronic devices.
1. Choose the right plastic material
High insulation performance materials: give priority to engineering plastics with high insulation performance, such as polycarbonate (PC), polyphenylene ether (PPO), etc. These materials have good electrical insulation and can effectively block current leakage, thereby protecting the circuits and components inside electronic devices.
Weather-resistant materials: Plastic parts choose materials with excellent weather resistance, such as PC, which has good UV resistance and can maintain its physical properties for a long time in outdoor environments. This material is particularly important for electronic devices that need to be used outdoors or in direct sunlight.
Wear-resistant and fatigue-resistant materials: Materials such as nylon (PA, polyamide) have the characteristics of high strength, wear resistance, and fatigue resistance. They are suitable for manufacturing transmission parts, bearings and other components of electronic equipment, which can reduce wear and fatigue damage and extend the service life of the equipment.
2. Optimize the processing technology
Precise process parameter control: plastic parts During the injection molding process, key parameters such as temperature, pressure and time need to be precisely controlled. Too high a temperature may cause thermal degradation of the material, while too low a temperature will affect the fluidity of the material, which in turn affects the quality of the injection molded parts. By precisely controlling these parameters, it is possible to ensure that the material fills the mold evenly, reduce defects, and improve the durability of the parts.
Optimize mold design: A reasonable mold structure helps to improve the durability of the parts. For example, design a suitable runner system to make the plastic melt flow evenly and avoid weld marks; at the same time, ensure the surface finish of the mold and reduce the local discharge phenomenon that may be caused by rough surface.
3. Enhance component performance
Add anti-aging additives: plastic parts Adding an appropriate amount of anti-aging additives such as UV absorbers and hindered amine light stabilizers (HALS) to plastic raw materials can effectively absorb ultraviolet rays, prevent photo-oxidation reactions, capture free radicals, and inhibit oxidation reactions, thereby extending the service life of the material.
Heat treatment: Heat treatment of injection molded parts can eliminate internal stress and improve the crystallinity and stability of the material. For example, keeping the component at a certain temperature for a period of time and then slowly cooling it can help improve the microstructure of the material and enhance durability.
4. Surface treatment technology
Surface coating treatment: By applying insulating paint or anti-aging coating on the surface of the shell, the insulation performance and anti-aging ability of the component can be further improved. Insulating paint can form a uniform insulating protective film on the surface of the component, while anti-aging coating can effectively block the erosion of external factors such as ultraviolet rays, oxygen and moisture.
Electroplating: Electroplating can provide a metal protective film for the component to enhance its weather resistance and wear resistance. For example, chrome plating can make the surface of the component have good corrosion resistance and wear resistance, which is suitable for parts that are often in contact with human hands or may be rubbed.
5. Product design optimization
Avoid stress concentration: During the product design stage, try to avoid stress concentration in the component. Sharp corners, sudden changes in wall thickness, etc. will cause stress concentration, making the component more prone to cracks and damage under the influence of environmental factors. Therefore, the corners should be designed as rounded corners, or a gradual wall thickness transition should be used to disperse stress.
Reasonable design of structure and size: According to the specific use environment of electronic equipment, the structure and size of components should be reasonably designed. For components used outdoors or in direct sunlight, the wall thickness should be appropriately increased or the structural strength should be strengthened; for components that may be exposed to chemicals, a sealed design should be adopted to prevent the intrusion of chemicals.
In summary, the durability of machined plastic parts in electronic equipment can be significantly improved by selecting appropriate plastic materials, optimizing processing technology, enhancing component performance, applying surface treatment technology, and optimizing product design. These measures not only help to extend the service life of electronic equipment, but also improve the reliability and stability of the equipment.
