Moldflow Analysis Case
Automotive Rearview Mirror
The automotive rearview mirror housing is a precision injection-molded component made of PMMA + ASA, combining high optical clarity for transparent areas and UV-resistant, durable ASA for structural support. This component is critical for vehicle safety and aesthetics, integrating functional design with premium surface quality.
Manufacturing Challenges:
Wall Thickness Variation: The housing has thin edges and thicker support ribs. The significant thickness differences can lead to uneven shrinkage and warpage during cooling.
Warp Control: Extended or protruding features are prone to distortion, which can affect both assembly fit and optical alignment.
Flow and Filling Issues: Complex internal ribs, mounting bosses, and transparent areas can cause short shots, weld lines, and trapped air, especially in PMMA sections sensitive to temperature fluctuations.
Gate Placement and Mold Design: Proper gate locations and optimized cooling channels are essential to ensure uniform filling, high surface quality, and minimal optical defects.
Dimensional Accuracy: Mounting interfaces and clip features must maintain tight tolerances for precise assembly to vehicle brackets, sometimes requiring secondary operations or high-precision mold design.
Benefits of Moldflow Analysis:
By performing Filling, Pressure, and Warpage simulations, our engineers can predict potential defects, optimize gate locations, fine-tune injection parameters, and design effective cooling systems. This ensures consistent part quality, reduced warpage, and improved production reliability, even for complex geometries and mixed-material components.
Supporting Clients’ Product Development and Manufacturing:
Moldflow insights allow clients to evaluate design feasibility, optimize manufacturing processes, and improve part quality across both existing and new mirror designs. By identifying challenges early, we help reduce trial-and-error cycles, accelerate development timelines, and guarantee that mirrors are produced efficiently, reliably, and to the highest quality standards.
Automotive Electronics Housing
This automotive electronics housing is a complex injection-molded ABS component featuring open areas, mounting holes, and extended arms for structural support. The part serves as a bracket or enclosure for in-vehicle electronic modules, such as dashboard sensors, control units, or infotainment system components.
Manufacturing Challenges:
Wall Thickness Variation: Long arms and solid support sections create significant thickness differences, which can lead to shrinkage and warpage.
Warp Control: Extended structures are prone to distortion during cooling, requiring careful mold cooling design and fixture planning.
Flow Difficulties (Filling): Central frames and support ribs can cause uneven material flow, potentially resulting in short shots, voids, or burn marks.
Gate Location and Type: Proper gate placement is critical to ensure uniform filling, especially in extended areas.
Dimensional Accuracy & Post-Processing: Mounting holes must maintain precise alignment, possibly requiring secondary machining or precise mold design.
Benefits of Moldflow Analysis:
By simulating Filling, Pressure, and Warpage, our engineers can optimize gate locations, cooling systems, and injection parameters. This helps reduce defects, control warpage, and improve dimensional accuracy, ensuring a stable, high-quality production process.
Supporting New Product Development:
The insights from our moldflow analysis also make it easier to explore new designs. By understanding potential challenges early, clients can iterate faster, adjust designs confidently, and bring innovative electronic housings to market with less trial and error.
