Compared to ordinary plastic molds, automotive armrest molds typically have the following characteristics:
High dimensional accuracy requirements: They need to be accurately assembled with the car door or center console assembly.
High surface quality requirements: Exterior parts typically require no shrinkage, no weld lines, and no obvious ejector pin marks.
Complex structure: Armrests often have clips, mounting holes, ribs, and undercuts, requiring mechanisms such as sliders and angled ejectors for molding.
Long production life: Automotive parts are produced in large batches, and mold life is typically required to reach hundreds of thousands to millions of cycles.
High degree of automation: Often used in conjunction with robotic arms for automatic part handling and online inspection, improving production efficiency and consistency.
