Injection Moulding Machine for Educational Toy Trays, Sorting Inserts and Storage Cases
Educational toy trays, sorting inserts and storage cases are moulded on horizontal injection moulding machines from PP copolymer, PS and ABS. Footprint of the tray or case sets clamping force, and compartment depth sets mould height. Flatness after ejection matters most, because a warped tray stops the lid closing and the set stacking.
Machine choice for these flat, compartmented parts depends on platen area, even cooling and steady shot-to-shot weight. Pratishna Engineers supplies horizontal injection moulding machines for educational toy tray and storage case production and can recommend a configuration.
Manufacturing Toy Trays and Cases?
Share the tray or case size, material and number of set parts, and Pratishna Engineers will recommend a machine.
Machine Requirements for Educational Toy Tray and Case Moulding
Trays and cases are flat, ribbed parts that must take a lid and stack, so the machine and process should handle:
- Large flat footprint with balanced filling across compartments
- Even cooling to keep trays flat after ejection
- PP living hinges gated across and flexed while warm
- Colour match across a set moulded on several tools
- Thin compartment walls filled without short shots
- Clear PS lids free of scratches and ejector marks
Recommended Machine for Educational Toy Trays and Storage Cases
Sorting inserts and small trays fit the E Series (75-180 T). Storage cases and large compartment trays run on the C Series (140-320 T), with the H Series (120-350 T) taking the widest family moulds, since platen area and tie-bar spacing must clear the tool.

FAQs / Buyer Questions
Questions makers of learning toy sets ask about trays, inserts and cases.
Which Injection Moulding Machine Is Used to Make Educational Toy Trays and Storage Cases?
Small inserts and trays usually sit in the E Series. Larger cases and multi-compartment trays need the C or H Series, sized by footprint, compartment depth and the number of parts per mould.How Are Living Hinges Moulded on Storage Cases?
Use PP, gate so the melt flows across the hinge rather than along it, and flex the hinge several times straight after ejection. That orients the polymer and gives a hinge that survives repeated opening.Why Do Tray Colours Differ Across a Set?
Parts in one set often come from several tools and machines. Differences in masterbatch dosing, melt temperature, regrind and resin lot shift the shade, so fix each one and check parts against a master sample.
How Is Warpage Kept Down on Flat Trays?
Keep walls and ribs even, cool both mould halves evenly and allow enough cooling time before ejection. Corner gates or several gates help fill wide trays without high pressure that locks in stress.Can Pratishna Recommend a Machine for My Toy Trays and Cases?
Yes. Share the drawings or samples, material, part weights, mould dimensions, number of cavities and the full set layout, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Learning Toy Parts Too?
Yes. It can also mould puzzle frames and shape sorters, building blocks, board game pieces and baby walker trays, depending on the mould.
