Production line and factory setup overview
A small thermoforming line producing rigid multi-cell nursery seedling trays from purchased PP or HIPS sheet through sheet conditioning, indexed heating, plug-assisted vacuum/pressure forming, in-mould or downstream cutting, hole punching, rim trimming, stacking, dimensional inspection and planting-performance trials.
Recommended lowest-entry line configuration Launch one 50-72 cell tray family on a four-station thermoformer using purchased sheet. Include one proven forming/cutting tool, drainage-hole tooling, chiller, air compressor, scrap granulator and tray/planting tests. Add a separate sheet extruder only after stable volume; a thermoformer alone cannot process loose resin.
Production process and implementation sequence
- Sheet receiving and lot release
- Heating and indexed sheet transport
- Plug-assisted forming
- Cooling and tool release
- Profile cutting and drainage punching
- Scrap separation and controlled grinding
- Counting and stacking
- Dimension, de-nesting and planting trial
Products, capacity and market fit
- Afghan vegetable, orchard and greenhouse nurseries need uniform transplant trays.
- Purchased sheet gives the lowest credible entry without a second extrusion plant.
- One cell geometry controls tooling and planting trials.
- Drainage, de-nesting, rigidity and root-ball release determine field usefulness.
- Reusable nursery seedling tray - Cell count, cell volume, depth, drainage, rim stiffness, nesting pitch, mass and colour - Commercial nurseries and greenhouse growers
- Crop-specific plug tray - Separate approved cell geometry and root-release trial - Vegetable or forestry propagation after validation
