Plastic Oil Container Blow Mold Design (HDPE – OEM Style)

Job ID: 40295081

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.

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.
