1. Advanced Die Casting Technologies

Shinhwa Auto possesses leading die-casting technologies to meet diverse requirements.

High-Pressure Die Casting (HPDC)
Utilizing machines up to 2500 tons, we excel at producing parts with highly intricate geometries and thin wall thicknesses.
  • Primary Applications: Complex EV motor housings, transmission cases, electronic enclosures.
Complex & Low-Pressure Die Casting (CPC/LPDC)
Optimized for the production of large structural components where mechanical integrity and minimal porosity are non-negotiable.
  • Primary Applications: Battery enclosures, shock towers, subframes, and other safety-critical chassis parts.
Innovation in Shinhwa Low-Pressure Casting Technology
Shinhwa Auto has developed proprietary Shinhwa Low-Pressure Casting technology that surpasses the limitations of conventional low-pressure casting, revolutionizing productivity and quality.
  • Method Features: Achieves uniform quality through a multi-cavity system (configurable 4-6 cavities) and precise control of the low-pressure liquid metal feeding device.
  • Cavity & Productivity: The multi-cavity (4-cavity) system boasts approximately 5 times higher productivity than conventional methods, enabling the production of 51 parts per hour.
  • Cooling Method: Employs a mist (water + air) cooling method, ensuring excellent cooling effects, directional solidification, and refined microstructure through reduced CT (cooling time) to maximize component strength and durability.
  • Application Cases: Proven excellence through participation in national projects (“Development of AL Knuckle for Semi-Midsize Cars Using Multi Cavity Low Pressure Casting”) and successful mass production and long-term supply of FAGOR (Spain) GM DELTA J300 / 309 Knuckles.
  • In-house Design Capabilities: Possesses proprietary product and mold design capabilities for core components such as knuckles and control arms.

3. Specialized In-House Finishing & Assembly

We directly control all final stages that determine a component’s ultimate performance and readiness for use.

In-house Heat Treatment (T6 & Carburizing)
By managing this critical process internally, we achieve precise control over the final metallurgical properties of your components, ensuring optimal strength, hardness, and durability.
Assembly & Painting
Our capabilities extend to the final assembly of multi-part components, such as Constant Velocity (CV) Joints, and in-house surface finishing, including Painting, supplying ready-to-use, near-finished parts to your production line.
Reduce Risk, Elevate Success with Our One-Stop Solution

The Power of Seamless Integration

Integrating such diverse advanced technologies under one roof creates powerful synergies beyond mere convenience.

Our casting experts work hand-in-hand with our machining engineers and assembly teams. This seamless, internal collaboration completely eliminates the communication gaps, unnecessary delays, and quality variances that can arise from using multiple external suppliers. The result is a faster, more agile, and significantly more reliable manufacturing process from product conceptualization to final mass production.
