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

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.
