Works

Each project we complete serves as a testament to our relentless commitment to precision, innovation, and excellence across a broad spectrum of industries. Delve into Seongju's expansive manufacturing portfolio to gain insight into our diverse capabilities, exemplified through the lens of the myriad projects we have successfully undertaken.

Hybrid Engine Mount

  • Since the late 1990s, Seongju has been a leading provider of engine mounts to OEM clients worldwide, essential for securing and supporting the engine to the vehicle's chassis in internal combustion engine (ICE) systems. Initially, our mounts were constructed from a simple yet effective combination of steel and rubber, adept at mitigating noise, vibration, and harshness (NVH) from engines, while maintaining manufacturing simplicity.

    Motivated by a commitment to excellence and innovation, Seongju's in-house R&D team embarked on a project to enhance the NVH performance of our engine mounts without complicating the production process.

  • The challenge was multifaceted, involving extensive analysis to identify the most effective approach to improve noise and vibration dampening. Was the solution in the materials used, the design, or a combination of both?

    After rigorous experimentation with various materials, compounding techniques, and designs, our R&D team made a groundbreaking discovery: the integration of a liquid layer within the rubber component of the mount. This innovative hybrid design significantly boosted the mounts' ability to absorb noise and vibrations.

  • This advanced engine mount concept quickly gained approval from our OEM customer, leading to the successful global supply of over 1,000,000 units.

    As the automotive landscape evolves towards electric vehicles (EVs), the relevance of ICE-specific components like engine mounts may wane. However, Seongju remains committed to producing high-quality engine mounts for ICE vehicles as needed worldwide. Simultaneously, our R&D efforts are increasingly focused on enhancing the safety, sustainability, and performance of EVs, ensuring Seongju's continued leadership in automotive innovation.

Engineering Plastic
Worm Wheel Gear

  • Traditional worm wheel gear systems in automotive steering are commonly manufactured from steel or other metals to meet the requirements for strength and durability essential for automotive applications. Yet, the inherent weight of metal gears introduces unwanted inertia, leading to a noticeable delay in steering response as perceived by drivers.

    Prompted by the innovative concept that engineering plastics could surpass the performance characteristics of metals, Seongju embarked on a pioneering journey to develop a plastic worm wheel gear system. This initiative aimed not only to lighten vehicles for enhanced environmental friendliness but also to improve handling dynamics, potentially elevating consumer satisfaction with our clients' vehicles.

  • Our team embarked on this ambitious project with a clear strategy, leveraging our extensive experience in material science and automotive engineering. The success of this project hinged on creating a perfect formula of resin mixing that will provide the necessary strength and wear resistance, coupled with the lightweight properties needed to achieve our goals.

    With the ideal material identified, our engineers utilized cutting-edge CAD software and simulation tools to design the plastic worm wheel gear. The iterative design approach we took ensured that the final product would seamlessly integrate with existing automotive steering systems while providing superior functionality.

    Prototyping was conducted using additive manufacturing process, which allowed rapid iteration and refinement. Rigorous testing followed, subjecting the plastic worm wheel gears to conditions that simulated real-world use.

  • The culmination of our efforts was the development of a new engineering plastic worm wheel gear that successfully passed rigorous OEM performance and quality assessments.

    The gear, markedly lighter than its metallic counterparts, significantly reduces vehicle weight, thereby improving fuel efficiency. Furthermore, its advanced plastic composite material ensures exceptional durability and wear resistance, reducing maintenance needs and extending lifespan.

    Today, Seongju proudly supplies over 2.3 million units of these innovative worm wheel gears annually to our customers, marking a significant achievement in our ongoing mission to advance composite material technology.

Electromagnetic Shielding
Engineering Plastic Panel

  • In the rapidly evolving landscape of automotive technology, manufacturers are integrating an increasing array of advanced technologies into their vehicles, particularly as the industry shifts towards electric vehicles (EVs). A critical challenge in this transition is preventing electromagnetic interference (EMI) among the myriad of electronic devices present in modern vehicles. From the Engine Control Unit (ECU), which oversees engine management, to sophisticated entertainment systems and the impending surge of data from Full Self-Driving (FSD) capabilities, the potential for EMI poses significant risks to vehicle functionality and safety. Traditional solutions have relied on metal plates for EMI shielding, but while effective, these add considerable weight, compromising fuel and battery efficiency in an era where sustainability is crucial.

  • Seongju's team of seasoned engineers identified a creative solution to this problem: replacing heavy metal plates with engineered plastic plates for electromagnetic shielding. This innovation promises to significantly reduce vehicle weight, enhancing efficiency without sacrificing EMI protection. Furthermore, the use of lighter plastic plates streamlines the assembly process, reducing energy consumption and contributing to the automotive industry's sustainability goals.

    In order to successfully carry out this project, Seongju’s R&D team focused on formulating a blend of resins and materials that possess excellent electromagnetic frequencies. After countless trial and error, our team was able to find the perfect balance of various materials that offer electromagnetic shielding properties akin to metals, while being light and durable for automotive use. This breakthrough was followed by the design process that involved intricate modeling and simulations to ensure that our plastic panels could seamlessly replace the metallic counterparts while offering superior performance.

  • Seongju’s multi-directional effort led to the successful development of lightweight engineering plastic panels that provide effective electromagnetic shielding, meeting the stringent requirements of automotive safety and quality standards. These innovative shields offer a significant reduction in weight, contributing to enhanced fuel/battery efficiency across all ranges of vehicle.

    The success of this project not only demonstrated Seongju’s capability in delivering high-performance, environmentally friendly automotive components but also set a new industry standard for combining functionality with sustainability in vehicle design.
