What you'll own

Part drawing and DFM review

Review part drawings and 3D models for mouldability before tooling is committed: wall thickness uniformity, draft angles, rib and boss proportions, radii, undercuts, parting line feasibility
Assess whether stated tolerances and GD&T; are achievable in the specified material, and push back with data when they aren't
Apply correct shrinkage factors per material and geometry; flag warpage and dimensional risk early
Advise design on changes that reduce tool complexity and cycle time without compromising the product
Own the cosmetic surface strategy — A-surface definition, gate and weld-line placement away from visible areas, texture and finish specification

Mould design data review

Review and approve complete mould design data packages from vendors before tool manufacture begins
Evaluate: cavity layout and count, runner balancing, gate type and location, cooling channel design, ejection strategy, venting, slide/lifter/core-pull mechanisms for undercuts
Verify mould base standards, steel grade and hardness selection,



and surface finish specification against part requirements and expected tool life
Assess parting line, shut-off conditions, and tool robustness for the intended production volume
Maintain a documented review checklist and sign-off record for every tool

Simulation and analysis
Run or commission flow simulation (Moldflow, Moldex3D or equivalent) to validate fill, packing, cooling and warpage before tool release
Interpret results into concrete design changes, not just reports
Predict and pre-empt common defect modes: short shot, sink, weld and flow lines, jetting, burn marks, splay, warpage, flash

Tool trials, validation and production support
Plan and attend T0 / T1 / T2 trials; drive systematic correction cycles to sign-off
Establish the process window and moulding parameters; support scientific moulding practice and DOE where helpful
Coordinate dimensional validation — CMM reports, first article inspection, cap
