Plastic crate machine is one of Haichen’s professional injection moulding machine.
The selection of specific models is based on the details of each plastic crate product.
Know the plastic crate you intend to mold.
Design the mould.
Select machine type: Hydraulic, hybrid or electric.
Calculate clamp tonnage requirements.
Calculate the injection unit size.
Selection of appropriate auxiliary machinery
Know the plastic crate you intend to mold.
The size of the plastic frame, its weight, and the scenario in which it is to be used (purpose).
The design’s individual load-bearing limits and stacking requirements are the initial requirements for its quality.
Plastic crate raw materials are generally pp or HDPE. pp products are easy to oxidise, easy to break after 1 year of use, HDPE long service life.
Plastic crate raw material is recycled material, if it is recycled material selection of bimetallic screw.
Generally do the programme, can recommend customers with bimetallic screw.
Plastic crates because of the injection weight is relatively large, the use of the production cycle is mainly consumed in the pre-moulding.
Therefore, when the order to focus on, screw threads to be special (deepening). Accelerate the material.
Design the mould.
According to the different sizes, textures and outer surface designs of the frame products, the corresponding mould design will be started.
plastic crate may have hollow corners, need to extract the core. Some do not need
plastic crate demoulding mode:
Manual
Top plate ejector
cylinder pull out
mould size one side need to increase 140mm,so totally will need near 300mm
Calculate clamp tonnage requirements.
plastic crate cycle time
Note: The pre-moulding time is longer.
Pre-moulding time is relatively long
Open and close the mould, to drive the slider, longer than the general product time.
Whether to use robot for ejection
Calculate the injection unit size.
Choose an injection molding machine that has an injection weight of about 1.2 times the overall weight of the plastic basket to complete the job.
Thickness of the plastic crate wall.
Thin need more injection pressure and speed.
And thus require more clamping force. Selection and matching plastic crate machine is to pay attention to whether to choose a larger machine.
Selection of appropriate auxiliary machinery
The products of Haichen Machinery have the advantages of high precision, high productivity, long life and low energy consumption, and the products will cover all the equipment you need for production and can be a one-stop solution for your production needs.
