Plastic Crates Injection Molding Machine is an optimized injection molding machine for plastic crates and containers injection molding.
Haichen plastic crate injection molding machine is dedicated designed according to most plastic crates features and constructions.
A professional crate injection molding machine should be optimized the injection unit (Screw, barrel, heating, etc), Clamping Unit (Clamping platen, clamping force, Ejectors, etc), and the machine’s frame & controlling system.
On the other hand,Haichen plastic basket injection molding machine is dedicated design for the plastic crates and containers manufacturing process with Bigger size of injection unit for huge injection weight, Special screw design for PP recycle material, Eco-friendly and Energy-saving, faster System Response, Faster Injection Speed.
Key evaluation indicators for plastic Crate injection molding machines
- Process Parameter Optimization Injection pressure
- Mold temperature
- Injection speed
- Cooling time
- Equipment Specifications Clamping Force
- Screw diameter to L/D ratio
- Theoretical injection volume and material adaptation
- Energy consumption and efficiency
Process Parameter Optimization Injection pressure
It directly affects the integrity of molten plastic filling mold and the structural strength of the crate.
That is to say,too much pressure can lead to flash, and too low can lead to underfilling.
Mold temperature
Controls the cooling rate, affecting the crystallinity and shrinkage.
For example, polypropylene (PP) crate require precise control of mold temperature to maintain dimensional stability.
Injection speed
High-speed injection can reduce cycle time, but avoid flow marks or cavitation issues.
Thin-walled pallets (e.g. 0.5-1.5mm) often require high-speed filling.
Cooling time
50%-80% of the total cycle time.
Optimizing the cooling time reduces warpage, e.g. by means of a thermostat for uniform cooling.
Equipment Specifications Clamping Force
Equipment Specifications Clamping Force according to crate size and material.
For example, standard Euro crate usually require a clamping force of 500-1000T.
Screw diameter to L/D ratio
Directly affects plasticizing efficiency and material shearing.
High L/D (16:1-20:1) is suitable for high viscosity materials such as HDPE.
Theoretical injection volume and material adaptation
It is necessary to match the weight of the tray.
And the actual injection volume generally accounts for 20%-80% of the theoretical value.
For example, HDPE with a single pallet weight of 5 kg needs to be selected with a theoretical injection volume of ≥ 6 kg.
Energy consumption and efficiency
The energy consumption of all-electric injection molding machine is only 1/3-1/4 of that of hydraulic press.
And the repeatability is increased by more than 30%.
