Plastic Oil Container Blow Mold Design (HDPE – OEM Style)
Budget: $200 – $1,000 USD
We are a lubricants manufacturing company looking for an experienced industrial packaging designer / mechanical engineer to design HDPE plastic oil containers for blow molding production.
The containers will be used on automatic filling lines and must follow a modern, smooth OEM design similar to major international oil brands.
A detailed PDF specification document will be provided to the selected freelancer.
What I need from you is a complete CAD package that can go straight to a blow-molding toolmaker, plus any recommendations that improve manufacturability without compromising those two features.
Container Sizes
1L, 2L, 4L, 5L
Unified neck & cap for all sizes
Technical Requirements
Manufacturing process: Extrusion Blow Molding
Material: HDPE
Compatible with automatic filling machines
Unified neck finish for all sizes
Integrated ergonomic handle
Reinforced bottom
Embossed logo and volume markings
Export-ready industrial design
Required Skills
Industrial Packaging Design
Blow Molding Container Design
Mechanical Engineering
SolidWorks or Fusion 360
Plastic Mold Design Knowledge
Budget
Open to proposals (prefer fixed price)
Please include:
Portfolio (blow molded containers only)
Estimated delivery time
Software used
Important Notes
Graphic designers without blow molding experience will not be considered.
Concept-only designs are not acceptable.
Prior experience with lubricant or chemical containers is a strong advantage.
Please apply with:
Portfolio of similar blow molding projects
Brief explanation of your experience
Proposed timeline and cost
Deliverables
• 3D CAD model of the bottle (STEP or IGES)
• 2D manufacturing drawings with critical dimensions and wall-thickness call-outs
• Handle and graduation geometry fully defined so they mold cleanly
• Assembly illustration or brief PDF showing cap fit and label panel locations
If you’ve designed similar lubricant or chemical containers before, that experience will be a strong plus. Let me know which CAD platform you prefer, your typical design-for-blow-molding workflow, and an estimated timeline to reach the final tool-ready files.
