Mechanical Product Exploded Animation Render

I need a concise 3D sequence in Blender that demonstrates a new mechanical product for a customer-facing presentation. The clip must clearly show two key moments:

• Exploded view – every component pulls apart in a logical order, pausing long enough for viewers to recognise the parts before smoothly collapsing back together.
• Operational functionality – after reassembly, the mechanism should run through a full cycle so buyers can see how it works. Only have 2 operation, turn right 90 degree and turn left 90 degree. During turning, some part will move(i'll share image)

I've provided STEP files and .pdf file or detailed reference drawings along with branding guidelines. From you I expect:

• A clean, well-organised .blend file compatible with Blender 5.1.
• A rendered video (1920×1080, H.264) and, if practical, a transparent PNG sequence for compositing.
• Still screenshots of both the assembled hero shot and the exploded frame.

Acceptance criteria
1. Part positions and hierarchy match my CAD.
2. Even, readable spacing in the exploded view; no mesh intersections.
3. Operational cycle loops without glitches, clipping, or unrealistic motion.
4. Materials, lighting, and camera moves feel polished and presentation-ready.

If you specialise in mechanical animation and can hit these points efficiently, let’s agree on timing and milestones so I can slot the finished piece straight into my product demo.
