Manufacturing Process

A Seamless, Vertically Integrated Process

From Digital Design to Flawless Delivery

At Shinhwa Auto USA, manufacturing is not a series of separate steps; it is a single, cohesive ecosystem designed for perfection.

We have mastered and integrated every critical stage of production under one roof—from initial design simulation to final validation and shipment. This vertical integration, powered by a state-of-the-art MES (Manufacturing Execution System), creates a “digital thread” that follows every component. This ensures that every part we produce is tracked, controlled, and optimized for world-class quality and on-time delivery.

Our Step-by-Step Path to Perfection

This is how we transform your complex designs into precision-engineered reality.

Step 1: Co-Engineering & Digital Simulation
Step 1: Co-Engineering & Digital Simulation
Before any metal is melted, the process begins in the digital realm. We partner with your engineering team, using advanced CAD/CAE software to simulate the entire casting process. We analyze molten metal flow, thermal dynamics, and potential structural stresses to optimize the part and mold design.
Step 2: Precision Casting (HPDC, CPC, LPDC)
Step 2: Precision Casting (HPDC, CPC, LPDC)
Once the design is perfected, raw aluminum is melted in our central furnaces and transferred to our automated casting cells. We select the optimal casting process—High-Pressure, Complex Pressure, or Low-Pressure Die Casting—to ensure your component is formed with the ideal balance of material integrity, minimal weight, and geometric complexity.
Step 3: Ultra-Precision Machining
Step 3: Ultra-Precision Machining
The raw casting is then moved to our fully automated CNC machining lines. Here, robots feed the components into over 100 high-speed machines where all critical surfaces, bearing bores, sealing grooves, and mounting features are machined to sub-micron tolerances.
Step 4: Specialized Heat Treatment
Step 4: Specialized Heat Treatment
To achieve the final, specified mechanical properties, components undergo heat treatment in our in-house facilities. Depending on the alloy and application, this may include T6 solution treatment for strength or specialized Carburizing for gear surface hardening.
Step 5: Assembly, Finishing & Testing
Step 5: Assembly, Finishing & Testing
We perform complex sub-assemblies, such as installing gears or CV joints, to deliver a more complete module. Every relevant component undergoes 100% automated leak testing to ensure perfect sealing. We also provide in-house finishing services like painting.
Step 6: Rigorous Final Validation
Step 6: Rigorous Final Validation
The final step is an exhaustive quality check. We use our advanced metrology lab, equipped with 3D Coordinate Measuring Machines (CMM), in-house X-Ray, and CT scanners, to verify that every dimension and internal characteristic meets your exact specifications.

The Digital Backbone: Our Smart Factory System

The brain of our operation is our next-generation MES. It connects every machine, records every process parameter, and assigns a unique digital identity to every part. This enables real-time production monitoring and provides 100% LOT traceability from raw material to shipped pallet.
