Injection Moulding Machine for Milk Crates
Milk crates are moulded on high-tonnage horizontal injection moulding machines, in single-cavity moulds, from food-grade HDPE or PP copolymer. The deep body and large projected area push clamping force high, and shot weight and mould height follow. Many grip and ventilation openings create weld lines, so gate layout and venting decide drop strength.
Machine selection for milk crates starts from clamping force and shot capacity, which usually sit above standard machine ranges. Pratishna Engineers supplies horizontal injection moulding machines and can review your crate and mould to advise on a suitable configuration.

Machine Requirements for Milk Crate Moulding
A milk crate is heavy, deep and full of openings, and it has to survive cold stores and repeated drops. Points to check:
- High clamping force for a large, deep projected area
- Injection unit sized for a heavy single-cavity shot
- Gate layout that keeps weld lines out of load paths
- Venting at grip and ventilation openings against weak welds
- Food-grade HDPE with colourant cleared for food contact
- Drop impact strength held at cold store temperatures
Recommended Machine for Milk Crates
Milk crates usually need more clamping force than the standard H Series (120-350 T) and PHM Series (160-350 T) provide. Each crate is reviewed on enquiry: share the part drawing, weight and mould size, and Pratishna Engineers will advise, including whether a special purpose machine built to application suits the requirement.

FAQs / Buyer Questions
Questions dairy and beverage crate makers ask about machine choice.
Which Injection Moulding Machine Is Used to Make Milk Crates?
Crate size and wall weight set the tonnage, which usually lands above standard machine ranges. Pratishna Engineers reviews each milk crate on enquiry rather than quoting a series directly.Why Is HDPE Preferred Over PP for Milk Crates?
HDPE keeps its impact strength better at low temperature, which matters in cold stores and when loaded crates are dropped. PP copolymer is used where the crate sees less cold handling.Why Do Loaded Milk Crates Split at the Openings?
Each grip and ventilation opening splits the melt flow and leaves a weld line. Poor venting, or a gate layout that puts welds in load paths, weakens them, and the crate cracks there under drop or stack load.
Can Recycled HDPE Be Used in Milk Crates?
It depends on the food-contact use and the buyer specification. Some buyers now ask for minimum recycled content, which has to be balanced against food-contact rules and colourant choice.Can Pratishna Recommend a Machine for My Milk Crate?
Yes. Share the crate drawing or sample, bottle layout, part weight, material, mould dimensions and output target, and Pratishna Engineers will review it and advise.Does the Machine Suit Other Material Handling Parts Too?
Smaller parts in this industry, such as plastic bins, crate and bin lids, dunnage trays and crate label holders, can sit within the H and PHM Series ranges, depending on the mould.
