Injection Moulding Machine for Agri Crates
Agri crates for fruit, vegetables and produce handling are made on large horizontal injection moulding machines, often two-platen presses, from HDPE or PP. Crate length and width set the projected area and clamping force, while crate height sets mould height and opening stroke. Side wall flatness matters most, since bowed walls stop crates stacking squarely.
For agri crates, selection looks at mould height and daylight, shot weight for a heavy ribbed part and cooling time on thick corners. Pratishna Engineers supplies two-platen and horizontal injection moulding machines for crate production and can recommend a configuration for your crate design.

Machine Requirements for Agri Crate Moulding
Agri crates are large, deep and ribbed, and they carry load when stacked, so the machine has to cover these needs:
- High clamping force for the full crate projected area
- Large mould height and opening stroke for deep crates
- Shot weight that fills the whole crate in one stroke
- Hot runner gating to balance flow across long walls
- Uniform cooling to keep side walls flat and square
- Venting at rib ends and around ventilation slots
Recommended Machine for Agri Crates
The Two-Platen PHM Series (160-350 T) suits crate moulds that are tall and heavy, as two-platen clamping gives generous daylight in a shorter machine. The H Series (120-350 T) can run smaller crates and shallow trays where mould height is moderate. Larger crates beyond this clamping range can be discussed on request.
Not Sure Which Machine You Need?
Send your crate drawing and mould dimensions to confirm clamping force and daylight.

FAQs / Buyer Questions
Common questions from crate manufacturers comparing machine types.
Which Injection Moulding Machine Is Used to Make Agri Crates?
Crate size decides it. The PHM two-platen series suits deep crate moulds within its range, the H Series fits smaller crates, and very large crates needing more clamping force are reviewed on request.Why Is a Two-Platen Machine Used for Crates?
A two-platen clamp offers a long opening stroke and large daylight without a long toggle, so a deep crate mould fits and the part clears the core. It also keeps the machine footprint shorter.Should Agri Crates Be Moulded in HDPE or PP?
HDPE gives better impact strength in cold stores and rough handling. PP is stiffer and holds shape under stacking load. Either grade should carry a UV stabiliser for crates kept outdoors.
How Is Side Wall Bowing Controlled on Crates?
Bowing comes from uneven cooling and shrinkage. Balanced cooling channels in the core, even rib design, enough holding pressure and steady mould temperature keep walls straight.Can Pratishna Recommend a Machine for My Agri Crate?
Yes. Share the crate drawing or sample, material, part weight, mould length, width and height, and your daily output, and Pratishna Engineers will recommend a suitable machine.Does the Machine Suit Other Agriculture and Farm Parts Too?
Yes. With a suitable mould, the same machines can produce nursery pots, seedling and nursery trays, poultry feeders and chick or poultry feed trays.
