About the job
Job Description
We are looking for an experienced mechanical engineer / machine designer to develop the complete technical design and manufacturing drawings for a grain packaging machine (vertical form-fill-seal type – VFFS).
The objective is to obtain a fully manufacturable machine design, including all mechanical drawings, assembly drawings, and technical documentation required for fabrication.
Project Scope
Design a semi-automatic or automatic grain packaging machine capable of:
Packaging rice, sugar, lentils, seeds, or similar dry grains
Filling range: 5g to 250g
Target speed: 50 bags per minute
Accuracy: ±1%
Bag type: Pillow bag (PE or laminated roll film)
Film width: To be defined during design
Deliverables Required
The freelancer must provide:
Complete 3D Design
Full 3D CAD model (SolidWorks, Inventor, or similar)
All sub-assemblies properly structured
Manufacturing Drawings
Detailed 2D fabrication drawings (PDF + DWG/STEP)
Tolerances and dimensions
Material specifications
Surface finishing indications
Mechanical Systems Design
Frame structure
Film unwinding system
Forming tube & collar
Vertical sealing system
Horizontal sealing & cutting system
Weighing or volumetric filling system
Discharge system
Bill of Materials (BOM)
Complete part list
Standard components (bearings, motors, pneumatic parts, sensors, etc.)
Recommended suppliers (if possible)
Technical Documentation
Assembly guide
Exploded view drawings
