Mechanical Engineer - Plastic / Metal Part - Trading, Factory - ETERNITY CONSULTANTS (HK) Ltd

Responsibilities

• Design and develop plastic / metal part with focus on structural integrity, durability, and functionality.
• Perform structural analysis (FEA), load calculations, and failure mode analysis for injection-molded plastic parts.
• Create detailed 3D models, engineering drawings, and tolerance specifications using CAD software.
• Select appropriate engineering plastics (e.g., PA6, PA66, POM, PC, PP, etc.) based on mechanical requirements, environmental conditions, and cost targets.
• Conduct design validation through prototyping, mechanical testing (tensile, fatigue, impact, etc.), and iterative optimization.
• Collaborate with tooling engineers, manufacturing teams, and suppliers to ensure design for manufacturability (DFM) and mass production feasibility.
• Improve existing designs for better strength-to-weight ratio, user ergonomics, and cost efficiency.
• Support product certification and compliance testing where required.

Qualifications

• Bachelor’s degree or above in Mechanical Engineering, Product Design, Materials Engineering, or related engineering fields (preferred).
• At least 3 – 5 years of relevant experience in product structural design.
• Strong proficiency in 3D CAD software (SolidWorks, UG NX or Rhino preferred).
• Knowledge of injection molding processes, mold design principles, and plastic material properties preferred.
• Experience in structural analysis (FEA using ANSYS, Abaqus, or SolidWorks Simulation) is highly desirable.
• Good understanding of mechanical engineering fundamentals: stress/strain, fatigue, creep, snap‑fit design, and locking mechanisms.
• Strong problem‑solving skills and attention to detail.
• Good command of English (spoken and written) for technical documentation and international collaboration.
• Willingness to work hands‑on in a fast‑paced environment.

Preferred Qualifications

• Knowledge of international standards (e.g., REACH, Bluesign, ASTM, or industry-specific safety standards).
• Familiarity with rapid prototyping (3D printing) and physical testing equipment.
