I. BMC injection molding products have the following advantages:
1. Excellent physical properties:
High dimensional stability: The linear expansion coefficient of BMC molding compound is (1.3-3.5) × 10⁻⁵K⁻¹, which is significantly lower than that of typical thermoplastics. This means that BMC injection molding products experience minimal dimensional change under varying temperatures, maintaining high dimensional accuracy and stability. Temperature has little effect on dimensional stability, but humidity has a more significant impact. However, its linear expansion coefficient is close to that of steel and aluminum, making it suitable for composite applications with these materials.
Excellent mechanical strength: Tensile, flexural, and impact strength properties surpass those of thermoplastics, and creep resistance is also improved. This enables BMC injection molding products to withstand significant external forces, making them suitable for applications requiring high mechanical strength, such as automotive parts and machinery manufacturing.
2. Excellent electrical properties: BMC injection molding products possess high dielectric strength, outstanding arc resistance (approximately 190 seconds), and excellent insulation properties. Therefore, BMC injection molded products are often used in applications requiring high electrical performance, such as electrical appliances, motors, radios, and instruments.
3. Excellent Heat Resistance: BMC injection molded products have a high heat deformation temperature of 200-280°C and can be used for extended periods at temperatures of 130°C. Even in high-temperature environments, they maintain excellent performance stability and are not susceptible to deformation, softening, or decomposition. They are suitable for applications in high-temperature environments, such as automotive engine peripherals and those surrounding heating elements.
4. Excellent Chemical Resistance: BMC injection molded products exhibit excellent corrosion resistance to water, ethanol, aliphatic hydrocarbons, grease, and oil, but are not resistant to ketones, chlorinated hydrocarbons, aromatic hydrocarbons, acids, and alkalis. In environments where they are exposed to chemicals, BMC injection molded products maintain excellent performance and enjoy a long service life.
5. High Molding Efficiency:
Short Molding Cycle: BMC can be molded or injected, making it suitable for mass production, improving efficiency and reducing costs. Complex Products Can Be Molded in One Place: BMC injection molding products can mold complex structures such as inserts, holes, platforms, ribs, and grooves in a single process, reducing subsequent processing steps and assembly, improving production efficiency and product quality.
6. Excellent Appearance Quality: Products offer a glossy appearance, pleasant feel, high surface finish, and vibrant, realistic, and adjustable colors, eliminating the need for surface treatments such as painting to achieve a superior appearance.
7. Environmentally Friendly: BMC injection molding products can reduce environmental pollution during production through optimized formulations and processes. Furthermore, BMC materials themselves are recyclable, meeting environmental requirements.
8. Processing Adaptability: BMC injection molding products can be customized with different injection molding equipment and process parameters to meet the processing requirements of products with various complex shapes and structures. Furthermore, they require minimal worker skills and are easily automated, saving labor.
II. Application Industries:
Industrial Application Scenarios
1. BMC injection molding products are used in high-temperature steel plant equipment components. They can withstand temperatures up to 150°C without softening or deformation, far exceeding the performance of traditional injection molding products. In high-stress environments, such as those involving frequently rotating gears and other transmission components, BMC injection molding's superior mechanical properties provide wear and pressure resistance, extending equipment life and reducing maintenance costs.
2. BMC injection molding products are a reliable choice for industrial manufacturing. In the chemical industry, they offer strong chemical resistance, protecting equipment from acids, alkalis, and other media. In the electrical field, they offer excellent insulation properties and high insulation resistance, ensuring power system stability under high voltages. They are suitable for applications such as substation insulators and motor insulation components.
Electronic and Electrical Appliances
1. BMC injection molding products can enhance the quality of electronic and electrical products. In electronic devices with high heat dissipation requirements (such as computer CPU heat sink housings), they provide excellent heat dissipation and ensure device stability. For electronic component housings requiring electromagnetic shielding, special materials can be added to achieve excellent shielding, preventing electromagnetic interference and maintaining signal purity, which is difficult to achieve with traditional injection molding.
2. BMC injection molding products bring new opportunities to the electronic and electrical industry. In the manufacture of consumer electronic product housings (such as mobile phone and tablet housings), they offer exquisite designs, rich colors and textures, high dimensional accuracy, and a perfect fit for internal components. Highly durable, it withstands everyday bumps and scratches, enhancing the user experience.
Automotive Industry
1. BMC injection molding products reshape the quality of automotive parts. Under the high-temperature and high-vibration environment of the engine compartment, engine-related components such as the intake manifold and throttle body maintain stable performance, preventing deformation or loosening due to high temperatures and vibration, ensuring efficient engine operation. For interior design, they can create high-quality, comfortable, and environmentally friendly interior components that meet strict environmental standards and provide a healthy and comfortable in-vehicle environment.
2. BMC injection molding products are trusted by the automotive industry. They are used in automotive brake system components, offering high strength and stability, capable of withstanding the tremendous pressure during emergency braking, ensuring reliable braking. In the suspension system, certain support components exhibit excellent elasticity and toughness under complex road conditions, enhancing handling, comfort, and driving safety.
