Production line and factory setup overview
A medium injection-moulding cell producing one nestable or stackable reusable HDPE fruit-and-vegetable crate through resin lot release and controlled blending, drying only where specified, servo injection moulding in a dedicated high-flow crate mould, robot or guarded part removal, gate trimming, cooling/conditioning, visual and dimensional inspection, handle/stack tests, drop and compression testing, hot-stamp or moulded identification and palletized dispatch.
Recommended lowest-entry line configuration Launch one 15-25 kg produce crate geometry in virgin or tightly controlled qualified HDPE using a roughly 400-550 t servo injection machine selected by mould-flow analysis, shot weight, tie-bar spacing and clamp force. Include one hardened crate mould, robot, granulator for clean in-house runners, cooling system and drop/compression/stack laboratory. Mixed post-consumer waste is not acceptable without washing, sorting, compounding, odour and food-chain risk validation.
Production process and implementation sequence
- Crate/stack system and mould-flow design
- Resin qualification and blending
- Servo injection and controlled cooling
- Robot/guarded ejection and gate trim
- Conditioning and dimensional inspection
- Handle, stack and nesting checks
- Drop, compression and creep tests
- Identification, palletizing and dispatch
Products, capacity and market fit
- Reusable crates reduce bruising compared with weak one-way packaging.
- Local crate pooling can serve orchards, wholesale markets and cold chains.
- One geometry controls mould investment and stack compatibility.
- Impact, compression, hygiene and nest/stack fit determine useful life.
- Reusable produce crate - Outer/inner dimensions, load, mass, material, ventilation, handles, stack/nest interface, drop/compression and washability - Orchards, traders, markets and cold chains
- Pool-identifiable crate - Same approved geometry with durable owner/lot marking or RFID provision - Managed returnable packaging systems
