Plastic Injection Molding Machine for Automotive Industry
Auto-parts made by hybrid injection molding machine
High-precision plastic injection molding machines boast outstanding response speed and stable control, even under extreme injection conditions, ensuring exceptionally high reproducibility. Hence, when it comes to producing complex plastic parts and interiors for automobiles and motorcycles, this type of machine demonstrates remarkable performance, delivering remarkable results.
In the automotive and motorcycle industries, the pursuit of lightweight components and fuel savings has become a mainstream trend. Manufacturers commonly employ engineering plastic parts containing glass fibers to replace traditional metal parts. As a result, automotive component structures and dimensional accuracy face extremely high demands and specifications.
Considering that some components relate to the overall safety of vehicles, the Certified Automotive Parts Association (CAPA) imposes stricter quality standards for automotive parts. Besides requiring structural and dimensional compatibility with specific standards to ensure compatibility with other vehicle parts, materials used in parts must also possess sufficient strength, durability, and safety. Additionally, CAPA also stipulates requirements for appearance quality, such as prohibiting defects like burrs or sink. These standards aim to ensure the safety, reliability, and appearance quality of automotive components meet expected levels.
The benefits of plastic injection machine to apply in the auto-parts production industry
To meet the demand for high-quality products, Top Unite introducing high-performance injection machines and offers comprehensive solutions to address evolving industry needs. In terms of injection and dosing systems, we have incorporated Bosch Rexroth electromagnetic valves for precise control over the injection process. With an opening time of only 25 to 45 milliseconds and a closing time of 10 to 25 milliseconds, this exceptionally high response speed helps maintain the stability of each injection, ensuring the final product dimensions fall within tolerance range while easily achieving user-set injection parameters.
Engineering plastics are rigid materials that require high pressure to inject into molds during the molding process. If the mold plate quality cannot withstand such high injection pressure, it may lead to mold platen bending or deformation, resulting in burrs on the product. To address this issue, Top Unite high-performance injection machines adopt FCD-600 spheroidal graphite cast iron mold plate, which can perfectly withstand extremely high injection pressure and speed, thereby ensuring the final product's quality.
Top Unite's high-performance injection machines not only excel in injection pressure and speed but also ensure stability and quality throughout the production process through robust mold plate designs, providing reliable and efficient production solutions for customers manufacturing plastic parts for automobiles and motorcycles.
Top Unite provides precision plastic injection molding machines.
