Operations, Safety & Training Manual
This travelling production facility converts recycled plastic into modular Stretch Beds designed for use in remote and Indigenous communities across Australia.
The facility is designed to be mobile, repairable, and bolt-together(no glue, no welding in the final product).
A flat-packable, washable bed made from recycled HDPE plastic (legs), galvanised steel poles (26.9mm OD × 2.6mm wall), and heavy-duty Australian canvas (sleeping surface). Assembles in ~5 minutes, no tools required.

ℹ️ Parts per bed (this ratio does not change)
1 side = 4 long leg pieces + 4 rectangular tab pieces · 1 bed = 2 sides + 2 poles + 1 canvas
Each side weighs ~10kg of recycled plastic (20kg total per bed).
✅ Key Design Insight
The canvas is the structural bracing. The frame will not stand upright without the canvas installed. this is by design. The canvas under tension between the two steel poles locks the leg assemblies in place and creates rigidity. Tell new operators this upfront so they don't worry when the bare frame splays.
The container is a mobile, enclosed workshop that houses fixed machinery for processing plastic, forming sheets, and cutting parts. Bed assembly happens outside (in a shed area) to keep the interior clear and safe.
Plastic Intake & Shredding
waste plastic → shredded feedstock
Sheet Forming (Heat Press)
shredded plastic → solid sheets (~90 min/sheet)
Cooling & Stabilisation
sheets rest overnight to avoid warp
CNC Cutting
sheets → leg pieces + rectangular tab pieces
Edge Finishing
bull nose router for smooth, safe edges
Parts Storage & Buffer
racks for legs, blocks, and offcuts
ℹ️ Material Flow: No Backtracking
Plastic moves in one direction only:
All offcuts go back to step 1. Zero waste.
⚠️ Hot Sheet Handling
Moving hot sheets from the heat press to the cooling press. Joey's learned technique: use the “pizza paddle” tool to slide sheets, don't grip directly. You don't have to be strong. Flip and slide techniques work well.
⚠️ Start-of-Day Safety Brief
Required at every new site setup and before any youth-led shift begins.
End-to-end process from waste plastic to finished bed.
Purpose: Reduce plastic into pressable chips.
💡 Joey's Tip
Jams happen. Expect to spend ~40 min unjamming occasionally. Just have patience, power off, clear it, and restart. If you have the bandsaw available, pre-cut pieces smaller before feeding.
Purpose: Fill steel frames with chipped plastic for pressing.
Purpose: Melt plastic chips into solid sheets.
ℹ️ Key Metrics
Cycle time: ~90 minutes per sheet
Max capacity: 6 sheets per day
Diesel consumption: ~25 litres per day during full production
Purpose: Stabilise sheet structure and prevent warping.
⚠️ Critical
If the CNC doesn't finish cutting a sheet, store it FLAT overnight. Uncut sheets that aren't stored flat will bow, and the individual leg pieces will be out of spec when cut.
💡 Joey's Tip
Getting sheets out of the steel frames can be stubborn. Melted plastic seeps into the gaps. Cut along the frame edge enough times and it should pop out. Don't get frustrated, just work at it.
Purpose: Cut sheets into three component shapes.
💡 Joey's Tip
The CNC was temperamental early on but is reliable now with the wifi fixed. It's basically just a sequence to remember. For community handoff, it should be simplified to button-pressing with clear error codes documented.
Purpose: Safety and clean finish.
Rule: No unfinished parts move to assembly.
Purpose: Prepare holes for assembly screws (CNC can't do this step).
⚠️ Jig Maintenance
Replace or rotate the pre-drilling jig regularly. The more you drill through the same hole, the wider it bores out, causing alignment drift that eventually compromises bed integrity during assembly.
💡 Joey's Tip
Pieces can be slippery when moving in quantity. Some pieces won't be millimeter-perfect, but they still work. A pole goes through, canvas creates tension, bed serves its purpose. Use clamps during assembly if holes are slightly off.

✅ Multitasking Opportunity
The heat press and CNC can both run unattended. Use those 90-minute press cycles and CNC cuts to do assembly, edge finishing, pre-drilling, or shredding at other stations.

ℹ️ Acceptable Tolerances (Working Definition)
💡 Joey's Tip
“I can be a bit of a perfectionist... I've had to go, actually, hang on, that'll be fine.” Finding that window of tolerance, what's genuinely bad vs what works fine, is important. Beds that aren't perfect can still serve their purpose.
Real-world learnings from Joey after 5–7 weeks of daily operation.
Each shift must record:
Use the Process Journal to log issues. Use the Shift Log for daily metrics.
This log travels with the facility.
This facility is designed so that unskilled operators can learn with proper support.
| Station | Skill Level | Key Training Need |
|---|---|---|
| Shredding | Basic power tools | Jigsaw, multi-tool, drill. Spotting jams |
| Sheet Prep | Low | Even spreading, frame locking |
| Heat Press | Medium | Safety with hot materials, timing |
| Hot Sheet Handling | Medium (most daunting) | PPE, pizza paddle technique |
| CNC | Low (when simplified) | Button-pressing, error codes |
| Edge Finishing | Low | Router safety, consistent technique |
| Pre-drilling | Medium | Jig use, straight drilling |
| Assembly | Low–Medium | Impact driver, alignment, clamps |

⚠️ No step is skipped
Safety and quality checks are mandatory at every stage.
We track improvement ideas as “efficiency tests”. Small changes we try, measure, and keep if they work. Log new ideas in the Process Journal.
Move heat press & cooling press closer
Reduces hot sheet carry distance and risk
Rotate pre-drilling jig every 50 uses
Prevents hole boring causing alignment issues
Move shredding to bandsaw area
Frees container for storage, safer cutting
Blue tub for plastic dust containment

Define quality tolerance window
Removes perfectionism bottleneck
✅ How to propose a new test

Repair instead of replace
Design for reuse
Keep it simple & accountable
Remember the purpose
