Mold Solution for Automotive Slide Rail Component
Product Requirements:
The component is an automotive part with stringent cosmetic surface requirements. The parting line (witness line) must be controlled within 0.03 mm.
Product Overview:
Material: PC+ABS. Surface finish: textured. Dimensions: 67 × 68 × 32 mm. Wall thickness: 1.5 mm. Mold cavitation: 1+1.
Mold Solution:
Due to the extremely strict cosmetic surface requirements, the mold was designed with the part placed horizontally for demolding. This approach incorporates a slide with an integrated lifter on the inner side. Although this structural design is much more complex than a vertical placement, the vertical orientation would result in a large height difference for the slide, making it impossible to maintain the parting line tolerance. Therefore, the horizontal slide placement was chosen. The mold is a 1+1 cavity configuration. Detailed mold flow analysis was performed prior to mold manufacturing to ensure balanced filling and uniform temperature distribution, thereby guaranteeing consistent color appearance.
Result Feedback:
Every detail of the mold was well executed from design to manufacturing, achieving a truly high-quality mold. The mold achieved mass production readiness at T1, and the customer is highly satisfied.
