By vantal In the wave of automobile lightweight, injection molding technology has become the core tool for structural optimization. Traditional metal parts are being replaced by high-strength engineering plastics. Taking the engine bracket as an example, the weight of glass fiber reinforced nylon material is reduced by 60%, and the temperature resistance is improved to 180¡æ, which can withstand the high temperature environment of the engine compartment. In addition, injection molding can realize the design of complex topological structure, optimize the internal skeleton layout of components through simulation software, and further reduce weight on the premise of ensuring strength, which provides key support for the endurance improvement of new energy vehicles.contemporaneity Custom Plastic Molding Design Our competitors have not made large-scale improvements, so we should get ahead of everyone in the project. https://www.tigerbrotherplastic.com/
The pursuit of miniaturization in electronics industry has promoted the extension of injection molding to micro-nano scale. When producing the filter housing in the 5G communication base station, it is necessary to form precise threads in a cavity with a diameter of 2 mm, which requires extremely high mold processing accuracy and injection stability. By using EDM and laser etching technology, the mold cavity can achieve micron-level accuracy, and with high-speed injection machine and low-viscosity materials, the melt can be ensured to fill the mold cavity in a very short time to avoid dimensional deviation caused by cooling.
Strict standards of biocompatibility in the medical field gave birth to special injection molding process. When producing artificial joints, it is necessary to use ultra-high molecular weight polyethylene, whose melt viscosity is more than 100 times that of ordinary plastics, and it is difficult to form by traditional technology. By developing low-temperature and high-pressure injection technology, combined with the optimization design of mold cooling water channel, the material can be filled at a low temperature of 180¡æ, avoiding molecular chain fracture caused by high temperature, and ensuring the wear resistance and service life of products.
