Hello, The key challenge with a food-grade screw cap is getting the thread, sealing interface, tolerances, and draft right together so the cap closes smoothly and remains leak-tight while staying practical for single-cavity injection molding. I’d develop the cap in SolidWorks around your bottle-neck dimensions, optimise the thread and sealing geometry for PP or HDPE, and prepare the production ready STEP and fully dimensioned drawing with tolerances, draft, and tooling notes. I’d also recommend the most suitable food-contact resin and provide a simple presentation render. Can you provide the exact bottle-neck dimensions and target order quantity? Best Regards, Atik

The seal is what usually breaks on jobs like this, so the thread profile needs to be exact for a leak-tight seal on a standard bottle neck. I will model this cap in Fusion 360, focusing on the thread geometry to ensure smooth engagement and no cross-threading, also building in comfortable ergonomics for repeated opening and closing. I will select Polypropylene for its food-grade certification and suitability for injection molding. The design will include generous draft angles for manufacturability on a single-cavity injection mold. I will not use any complex undercuts or internal features that would require multi-part molds or complicate the injection molding process for mass production. What is the specific internal thread pitch and diameter for the bottle neck? 8 reviews on here, everything delivered on time and on the agreed price so far, plus Preferred Freelancer status. I need the bottle neck dimensions to start the CAD work.

Hi, I’d be interested in developing this bottle cap. I’m a product designer with hands-on experience in plastic product development, SolidWorks and injection-molding design. I can develop the cap with manufacturability in mind, including thread geometry, sealing, tolerances and appropriate draft angles for injection molding. I can provide: - SolidWorks 3D model + STEP - Fully dimensioned 2D technical drawing - Thread and tolerance specifications - Draft-angle considerations - Material and basic tooling recommendations - A rendered image for presentation I also have experience working with injection-molded plastic components and evaluating designs according to manufacturing constraints. For food-contact applications, I can recommend suitable PP/HDPE grades based on the required application, while the final food-contact compliance should be confirmed with the material supplier. Before starting, I would need the bottle-neck dimensions, target application/requirements, branding requirements and expected production volume. From these inputs, I can develop the cap geometry, thread, sealing features, tolerances and draft angles with injection molding in mind.
