Automotive Plastic Parts Moulds
The mirror housing project centers on cosmetic-surface sink marks, parting line, snap-fit, lens-holder mounting position — helping you understand the main structural risks and mould approach before submitting drawings.

Mirror Housing mould, focused on cosmetic-surface sink marks and parting line.
For mirror housing mould, review cosmetic-surface sink marks and parting line alongside snap-fit and lens-holder mounting position. Mark these features on the current drawing and state the material, appearance and assembly requirements so that the tooling discussion uses agreed part references.
For the mirror housing project we recommend front-loading risk into the DFM stage, building the mould solution around cosmetic-surface sink marks, parting line, snap-fit, lens-holder mounting position.
The project starts by assessing cosmetic-surface sink marks, confirming structural, cosmetic and assembly risks to reduce later mould rework.
In the mould-solution stage we focus on parting line, arranging core, cavity, inserts, ejection and cooling for stable moulding.
During trial-mould we watch snap-fit on the sample part, tuning venting, ejection or local structure to the actual part condition.
Before mass production we keep reviewing lens-holder mounting position, keeping the automotive plastic parts moulds project consistent in dimensions, appearance and assembly feedback.
Send the following to start an assessment: 3D/2D drawings, sample photos, material requirements, expected quantity and lead time — we assess from structure, material, mould risk and trial-mould plan.
