Description

CD151-C020-1000 is a precision automotive component made of Mitsubishi 5710G30LWB black raw material through injection molding. This product has strict requirements for optical performance and structural accuracy. Specific areas must ensure a light transmittance of over 30% (@980nm) and a high surface finish of Ra0.8 to support the laser welding process (with a penetration depth of 0.4±0.02mm). The product surface is treated with VDI3400 CN-V0024 fine sandblasting texture, and the appearance must be free of defects such as brushing and sink marks, while strictly complying with automotive prohibited substance standards. The overall flatness is ensured through pre-deformed mold design, making it suitable for electronic or sensor module housings in vehicles that require high assembly accuracy (misalignment ≤0.3mm) and sealing performance.

Features

  • The appearance is full and free of brushing, with uniform color, and no defects such as sink marks, cracks, or silver streaks
  • Fine sanding pattern on the outer surface
  • Regular floating fiber pattern, exhibiting a gate divergence effect
  • The assembly with the corresponding components is smooth, and the misalignment of the planar mating surface is ≤ 0.3 mm
  • After trimming, the flying edge is ≤ 0.3 mm, without damaging the main body
  • The indentation of the thimble is 0.2 mm below the surface of the workpiece
  • After trimming, the sprue has a neat and aesthetic shape, with a height of ≤ 0.3 mm,
  • The depth of indentations/indentations such as material labels and date stamps should be ≤ 0.3 mm, and they should not protrude beyond the outer surface
