Car Bumper & Dashboard

Automotive parts molds are primarily categorized into four major types: stamping dies, injection molds, die-casting molds, and forging dies.
1. Stamping Dies: Used to produce body panels (e.g., doors, hoods) and structural components (e.g., frames) by forming sheet metal through processes like blanking, drawing, and bending. Their advantage lies in rapidly manufacturing complex curved parts, completing multiple operations in a single press stroke, offering high efficiency and low cost.
2. Injection Molds: Used to manufacture plastic interior components (dashboards, door panels) and exterior parts (bumpers, grilles). Plastic is melted under high temperature and pressure before being injected into the mold cavity. Advantages include the ability to form intricate shapes, high surface precision (high-gloss injection molding achieves seamless, high-shine finishes), and support for mass production.
3. Die-casting molds: Primarily used for aluminum and magnesium alloy components (e.g., engine housings), where molten metal is injected into cavities under high pressure. Key advantages include rapid forming of intricate structures.
4. Forging dies: Employed to manufacture high-strength metal parts (e.g., connecting rods, gears) through high-temperature plastic deformation, achieving dense microstructures. Key benefits include producing precision components capable of withstanding heavy loads, with service lives reaching hundreds of thousands of cycles, and high material utilization rates.
