🧩 3D Modeling & Design:

SolidWorks (95% solid modeling, 5% surface modeling), basic sheet metal modeling knowledge.

Creation of precise assemblies, constraints, tolerance verification, and preparation of models for molding production.

Ability to break down complex projects into sub-units, using reference geometry and configurations.

🏭 DFM / DFA / Manufacturing:

Knowledge of mold design: opening directions, gating points, parting lines, risks of short shots/air pockets.

Optimization for scalability and cost reduction (minimize part count, reduce weld lines, shorten cycle time).

Experience working with factories in Ukraine and China; understanding of the mold lifecycle; participation in modifications after T1/T2.

Basics of metal processing technologies: bending, stamping, laser cutting, milling for internal frames and auxiliary parts.

Understanding of Chinese manufacturers’ practices: interpretation of drawings, overlooked details, confirmation processes.

Understanding of the Chinese production structure: project managers, engineers, suppliers.

Active participation in mold development discussions: steel selection, cost estimation, gating points, parting lines.

Familiarity with typical Chinese documentation formats: PDFs, STEP files, Excel specifications, compressed archives, WeTransfer/Alibaba Cloud.

🧪 Testing & Prototyping:

Manual inspection, assembly, and analysis of critical nodes.

Identifying and resolving sealing, play, and fit issues.

Skilled in the use of measuring tools: calipers, micrometers, gauges, etc.

🧠 Materials Science & Standards:

Properties of ABS, PC, PC+ABS, PA+GF, TPE, and TPU: shrinkage, impact strength, heat resistance, and elasticity.

Understanding material behavior during production and operation (temperature, humidity, UV).

Balancing cost, quality, and manufacturability when selecting materials.

⚙️ Functional Elements:

Development of fasteners, clips, guides, seals, TPE/TPU elements, and mounting slots.

Design of interface elements: buttons, indicators, light guides, ports, and ventilation openings.

Knowledge of sealing methods and IP protection standards (IP54–IP67), heat dissipation, and battery compartment design.

Considering Chinese factory constraints: wall thickness, micro gaps, welding, and assembly limitations.

Designing for high repairability and ease of assembly in outsourced Chinese facilities.

📄 Documentation & Production Support:

Generation of complete documentation bundles: 2D outlines, tolerance tables, BOMs, assembly specifications.

Implementation of changes based on prototype or production feedback.

Participation in preparing technical descriptions for QC, assembly instructions, and design documentation control.

🌐 Communication & Tools:

English B2+ level – oral and written technical communication with Chinese suppliers.

Experience in communication with Chinese engineers, managers, and production teams (via Alibaba, WeChat, email, video calls).

Knowledge of Chinese business communication nuances: importance of confirmations, repetitions, and visual examples.

Use of SolidWorks PDM, Excel, Google Docs, Asana/Trello/Notion for project management.
