Production line and factory setup overview
A small injection-moulding cell producing one durable nestable PP flowerpot family through resin release, controlled blending, servo injection into a vented pot mould, guarded or robotic removal, gate trimming, cooling, drainage finishing where required, decoration or marking, nesting, dimensional and load testing and packing.
Recommended lowest-entry line configuration Launch one 15-25 cm durable pot with integrated drainage on a roughly 150-220 t servo press selected from the final mould-flow analysis, shot weight, projected area and tie-bar spacing. Include one hardened mould, robot or guarded take-out, cooling, clean-runner granulator and load/UV tests. Thin thermoformed nursery pots are a separate process.
Production process and implementation sequence
- Product and mould-flow approval
- Resin release and blending
- Servo injection and cooling
- Guarded or robotic demoulding
- Gate trim and drainage finishing
- Decoration and nesting
- Dimension and load tests
- Packing and dispatch
Products, capacity and market fit
- Urban landscaping, nurseries and household gardening create repeat demand.
- One nesting geometry minimizes mould cost and transport volume.
- Controlled clean recycled PP can be evaluated for non-food outdoor pots.
- UV retention, rim strength, drainage and colour consistency determine useful life.
- Durable nestable flowerpot - Top diameter, height, volume, wall, drainage, rim load, nesting pitch, colour and UV class - Nurseries, landscapers and households
- Matching saucer expansion - Separate mould and watertightness/fit specification - Indoor and retail pot sets
