Automatic PET Blowing Machine Design

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.
