Tooling / Mould Engineer — Injection Moulding

SB eCommerce Solutions Pvt Ltd; New Delhi; On-site; INR 1,200,000 - 2,200,000; Full time

Job summary

SB eCommerce Solutions Pvt Ltd in India seeks an experienced mould tooling engineer to review designs, validate tolerances, and drive tooling programs. You will lead CAD-based reviews, advise design changes for manufacturability, and coordinate tool trials and vendor interactions, ensuring cosmetic surfaces and robust tool life.

The role requires hands-on experience with small precision parts, mould bases/steels, and flow simulations, with willingness to travel for toolroom work and overseas

Qualifications

• 5+ years in injection mould tooling, design or tool-side project engineering.
• Direct experience with small precision parts like mobile handset housings.
• Review and red-line part drawings and mould designs independently.
• Strong 3D CAD skills and GD&T knowledge.
• Familiar with mould bases, steels and thermoplastics.
• Willingness to travel to vendor toolrooms, including overseas.

Responsibilities

• Review part drawings and 3D models for mouldability before tooling is committed.
• Assess tolerances and GD&T for manufacturability in material, flag risks.
• Apply correct shrinkage factors and flag warpage early.
• Advise design changes to reduce tool complexity and cycle time.
• Own cosmetic surface strategy and texture/finish specifications.
• Review and approve mould design data packages from vendors.
• Evaluate cavity layout, gate location, cooling, ejection, and undercuts.
• Run flow simulations and translate results into design changes.
• Plan tool trials, sign-off, and establish process windows.
• Coordinate dimensional validation and root-cause analysis.
• Manage toolroom vendors, quotes, transfers and life-cycle planning.

Job description

• 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 useful
• Coordinate dimensional validation — CMM reports, first article inspection, capability studies (Cp/Cpk)
• Troubleshoot production defects and separate tool causes from process, material and machine causes
• Own preventive maintenance schedules, spares planning and tool life tracking across the tool bank

Vendor and cost management

• Manage toolroom vendors in India and overseas (China, Taiwan) — technical negotiation, timeline governance, quality accountability
• Evaluate tool quotations on engineering merit, not only price; build and defend tooling cost estimates
• Handle tool transfers, refurbishment decisions and end-of-life planning
• Support multi-material work: overmoulding, two-shot and insert moulding (for example rigid shell with soft-touch elastomer)
• Support in-mould decoration and in-mould labelling (IMD / IML) tooling, where decoration is integrated into the moulding step rather than applied afterwards

What we're looking for

Must have

• 5+ years in injection mould tooling — mould design, tooling engineering, or tool-side project engineering
• Direct experience with small precision parts: mobile handset housings and covers, consumer electronics enclosures, or comparable cosmetically critical components
• Proven ability to review and red-line both part drawings and mould designs independently
• Strong 3D CAD — SolidWorks, NX, Creo or CATIA — plus 2D drawing interpretation and GD&T
• Working knowledge of engineering thermoplastics and their moulding behaviour: PC, ABS, PC/ABS, TPU/TPE, PMMA, PP, nylon, and filled grades
• Practical familiarity with mould base standards (HASCO, DME, LKM, MISUMI, Futaba) and mould steels (P20, H13, S136, NAK80, 718H)
• Hands-on trial and debug experience on the shop floor, not only desk-based engineering
• Willingness to travel to vendor toolrooms, including overseas

Good to have

• Flow simulation capability — Autodesk Moldflow, Moldex3D or Sigmasoft
• Mobile handset industry background (Noida, Sriperumbudur or Tirupati clusters)
• Two-shot, overmould or IMD/IML tooling experience
• Chinese toolmaker experience and comfort managing across the language and time-zone gap
• Metrology depth — CMM programming, GR&R, PPAP documentation
• Working Mandarin (useful, not expected)

What we're not looking for

An engineer whose experience is entirely in large automotive or appliance tooling. The discipline of small cosmetic parts — sub-millimetre wall sections, tight cosmetic tolerances, gate vestige control on visible surfaces — is a genuinely different craft, and we'd rather hire for it directly.
