Plastic crate injection molding machine is an industrial equipment specifically used for the production of plastic crates.
Its core function is to heat and melt thermoplastic plastics (such as PP, HDPE) or thermosetting plastics.
Then inject them into the mold cavity under high pressure, and after cooling and solidification, form a box structure.
How many types of crates can the injection molding machine produce
Disposable type
- fruit crates
- beverage crates
- pharmaceutical packaging boxes
- postal packaging boxes
- postal packaging boxes
- pluggable crates
The general material is (PP), injection moulded in one go, the weight of the fruit crate is light, it has good ductility, impact resistance, high tensile strength.
In addition to this, the product also has good cache shock resistance, high stiffness, excellent bending characteristics and other quality physical properties.
The material can be recycled for multiple use, the recycling loss rate is low, the cost is relatively low.
Reusable (thickened type)
- flame-retardant crates
- anti-static crates
- conductive crates
- parts crates
- instrument crates
- pesticide crates
- inner packaging of precision instruments
- pharmaceutical packaging boxes
- electronic components packaging pads
- partitions
- fruit crates (thickened type)
- insertable crates
- insertable crates
- foldable crates
- beverage crates (thickened type)
These crates employ high-density polyethylene, specifically injection-moulded in one go.
Additionally, they exhibit high strength, excellent low-temperature impact resistance, and superior stress crack resistance.
Moreover, their chemical resistance, ageing resistance, and long service life ensure durability.
Furthermore, the material provides good flexibility, low water flow resistance, and significant wear resistance.
Crucially, it is recyclable with minimal loss, enabling multiple reuse cycles.
However, the cost remains slightly higher compared to disposable alternatives.
How to choose an injection molding machine for crates
If you are new to the production of plastic crates products, perhaps a lightweight disposable crate is the right choice for you, and our HCK range is more than adequate for this purpose.
We have used the HCK230 plastic injection molding machine to produce 250*150*20 fruit collection frames in our previous projects and the HCK310 for 400*300*20 frames weighing 400g and similar food totes, which are characterised by short cycle times and high production volumes.
The benefits of this are lower overall production costs, fast production rates to help meet your sales needs and quicker production experience and recover the investment.
The process of producing plastic crates by injection molding machines
Material preparation
Store the raw materials in storage or pre-match the colors and mix the masterbatch in a certain proportion.
Injection moulding
In this process, the prepared PP HDPE material is injection moulded by an injection moulding machine.
Injection moulding is carried out by an injection moulding machine, which injects the material into the mould.
Precise cooling control
After each cycle will determine the quality of the finished crate.
We use an air-cooled cooler for this process, and in addition, you can choose precise mould temperature control.
After opening the mould
The finished plastic crates are removed according to the different ejection forms.
Re-enter the next production environment
This is a complete production process. Continuous circulation can continuously produce crates.
Haichen Special Plastic crate injection molding machine
If you are already well versed in the field of crates and have higher requirements for your product quality and output.
We have a higher configuration HCK-SG plastic injection molding machine series of crates for the production of reusable (thicker type) baskets.
Which are heavier and require higher technical requirements for the production machinery.
We have developed a heavy duty frame production model for these products.
Which continues the HCK We have developed a heavy-duty frame production machine for this type of product.
Which continues the classic design platform of HCK, but with a highly efficient plasticising assembly.
Specially designed to cope with the characteristics of HDPE material, with highly wear-resistant injection moulding parts and easily replaceable nozzles.
Which can be used for a wide range of frame sizes.
The high quality of the finished product is maintained while significantly increasing your production efficiency.
Haichen’s customizable crates injection molding machine production line
Plastic crates are also sturdier, meaning they can withstand shock, impact, and stress when selected, packed, and moved in and out of storage.
In their production process, the fullness of the injection volume and the strength of the mold clamping mechanism are a balance state of dynamic demand.
Therefore, starting from the design of the mold, finishing, runner distribution.
And matching with the injection molding machinery, every step needs to be precisely controlled according to your product needs.
The products of Haichen Machinery have the advantages of high precision, high productivity, long life and low energy consumption.
Which are very suitable for plastic crates, the products will cover all the equipment you need for production and can be a one-stop solution for your production needs.
