The posting

Rubber Mold Tooling Design Engineer

5 days, 8.30am- 6pm

Salary: $4000-$5000

Location: 11 Fourth Lok Yang Road, Singapore 629708 (Joo Koon)

Company:

Manufacturer of high precision parts and tooling used in semiconductor manufacturing

Job scope:

Mold design and engineering

  • Review part drawings, critical dimensions, tolerances, surface requirements, material specifications and production needs; identify feasibility issues before releasing a mold design.
  • Develop two-plate and three-plate compression mold concepts, assemblies, component drawings and bills of materials in SolidWorks and AutoCAD.
  • Define cavity arrangement, parting surfaces, plate alignment, inserts, venting, flash control and demolding arrangements appropriate to the part and compound.
  • Establish and validate shrinkage allowances using compound information, prior production evidence and trial measurements. Record the conditions supporting each allowance.
  • Select suitable tooling materials, heat treatments and surface treatments with manufacturing and suppliers, considering dimensional stability, finish, wear, repairability and cost.
  • Check mold compatibility with the intended press, including usable area, mounting, opening, loading, heating and handling arrangements.

Tooling manufacturability and fabrication oversight

  • Review designs with the toolroom/manufacturing team for machining access, achievable tolerances, inspection access, assembly, fitting and ease of maintenance.
  • Simplify difficult features and standardise reusable components where this improves quality, lead time or cost without compromising requirements.
  • Coordinate internal fabrication and external tooling suppliers: communicate drawings and revisions, resolve technical queries, monitor progress and review inspection results.
  • Investigate tooling nonconformances and repeated machining, fitting or assembly rework; agree corrective actions with the responsible manufacturing team.
  • Maintain controlled design files, revision histories and technical records through fabrication and modification.

Mold trials and molding process development

  • Plan and lead trials with technicians and production personnel; agree sample requirements, inspection methods and acceptance criteria before testing.
  • Establish and refine material charge/preform preparation, loading sequence, mold temperature, pressure, curing time, venting/degas steps where applicable, and demolding conditions.
  • Assess cavity-to-cavity consistency, dimensional results, flash, surface defects and part damage; document trial conditions, findings and required changes.
  • Verify relevant post-cure effects with the responsible materials or process specialist when the compound and application require post-curing.
  • Prepare the technical evidence for tooling acceptance and production handover, including drawings, trial reports and molding setup instructions.

Troubleshooting and yield improvement

  • Diagnose tooling and molding issues such as excessive flash, incomplete filling, trapped air, sticking, dimensional variation, misalignment and premature tool wear.
  • Separate tooling design/fabrication causes from compound variation, press conditions, handling and process settings; use controlled trials and measurement data to confirm causes.
  • Implement and verify design or process changes with engineering, manufacturing and quality personnel.
  • Track tooling fabrication acceptance/rework separately from molded-part acceptance/scrap, so improvements address the correct stage.
  • Improve cycle time, usable cavity output, material utilisation and tool availability while maintaining agreed quality requirements.

Tooling repair and maintenance

  • Assess tool condition and plan repairs, refurbishment, spare inserts and replacement of wear components.
  • Establish mold inspection, cleaning, preservation, storage and preventive-maintenance instructions with technicians and manufacturing.
  • Define checks and repeat trials needed after repairs or modifications before returning a mold to service.
  • Build a practical library of proven designs, trial data, recurring defects and corrective actions.
  • Allocate technician tasks, review workmanship and records, and train technicians in mold handling, assembly, trial execution and defect identification.

Requirements:

  • Diploma or degree in Mechanical, Manufacturing, Tooling/Tool and Die Engineering, or a related discipline
  • Min 5 or more years of relevant mold design/tooling engineering experience
  • Practical experience designing two-plate and three-plate compression molds, with evidence of taking designs through fabrication and trials
  • Proficiency in SolidWorks and AutoCAD for mold assemblies, detailed drawings and revisions
