I need a full mechanical design package for an automatic PET bottle-blowing machine, from concept through to production-ready drawings. The priority area is the blowing unit itself, so every decision you make for the wider machine must integrate smoothly with that module. Blowing unit requirements: • Material type: choose grades that can handle food-grade PET contact and repeated thermal cycling without fatigue. • Pressure capacity: the unit must safely sustain the high-pressure air bursts typical of 2-stage stretch blow molding, designed with a generous safety factor. • Temperature resistance: components must tolerate the preform heating zone’s radiant heat as well as the sharp pressure-induced temperature drops during blowing. Scope of work includes: - Overall machine concept & layout - Complete 3D CAD model of the entire machine (SolidWorks required), including frame, preform heating section, blowing station, robotic or linear transfer, and discharge conveyor. - Detailed mechanical design for the blowing-unit - Detailed manufacturing & assembly drawings with tolerances and exploded views - FEA / pressure & thermal calculations showing performance and reliability of key components - Bill of Materials (BOM) specifying alloys, seals, and off-the-shelf components - A detailed design report summarizing key decisions, compliance standards followed, and maintenance considerations. - Final exports in native SolidWorks files as well as STEP/IGES formats are required. The package must also include all supporting documentation. If you already have experience designing PET stretch blow molders or similar machinery and can ensure efficient cycle times with high reliability, please share relevant examples.

Hi, Designing an automatic PET blowing machine requires careful integration of the bottle-forming mechanism, preform heating, moulding, pneumatic system, and automated motion/control system. I can develop the complete mechanical design with manufacturability and machine reliability in mind. I can provide 3D CAD assembly, detailed manufacturing drawings, mechanism design, pneumatic arrangement, component selection, and BOM, with proper consideration of cycle time and bottle dimensions. Could you share the required bottle volume/shape, production capacity (bottles/hour), and preform specifications so I can propose the machine configuration? Best regards, Arati M.

Yes—but for this project I would separate conceptual/mechanical design assistance from certified pressure-equipment and machinery engineering. A PET stretch-blow machine contains high-pressure pneumatic energy, heated components, moving mechanisms and pressure-containing mould/manifold components. I can help develop the architecture, CAD strategy, design documentation, calculations framework, BOM structure and verification plan, but I would not represent an unverified CAD/FEA package as proving that a pressure vessel or machine is safe for production. The final pressure design should be checked and signed off by an appropriately qualified engineer against the standards applicable in the machine's jurisdiction.

Hello, I reviewed the PET stretch blow moulding requirements carefully. The blowing unit, high pressure air system, thermal cycling, material selection, safety factors, and FEA make this a demanding production engineering project. My professional background is primarily software, embedded systems, automation, and engineering technology rather than mechanical CAD. I therefore do not want to claim PET blow moulding or SolidWorks experience that I cannot personally substantiate. If the project also requires machine control software, PLC or MCU integration, sensors, automation logic, monitoring, or production data systems, I can contribute strongly in those areas based on my 10+ years of software development experience. For the complete mechanical design package, I recommend a mechanical engineer with direct PET moulding and pressure-system experience. Best regards, Bojan Spasic
