Haichen HCK 700 ton Injection molding machine for Plastic chair Plastic chair Injection Mould chair making machine
Injection Molding Process
Raw Material Handling and Plasticization
Plastic particles (such as PP, PE) are conveyed to the hopper through a vacuum suction machine, and then heated to a molten state by entering the screw barrel (typical temperature range: 180-260°C).
For recycled materials (such as the waste snakeskin bags used in the Pakistan case), they need to be pre-treated such as smelting, crushing, and secondary processing.
Injection stage
The molten plastic is injected into the closed mold through a nozzle at high pressure (70-120 MPa), and the filling time needs to be precisely controlled to ensure that the melt is evenly filled.
The injection rate is usually in a "quick injection" mode to avoid premature cooling of the melt.
Holding & Cooling
Holding phase (25-35 seconds, pressure 70 Bar) compensates for shrinkage of the material and prevents denting.
The cooling time is adjusted according to the thickness of the product (25-60 seconds), and the mold temperature is controlled at 40-100°C to ensure structural stability.
Demoulding and post-processing
After the robotic arm automatically takes out the product, it carries out manual treatment such as burr repair and installation of anti-slip pads.
We are Haichen machinery, have own medium-sized factory in Ningbo over 10 years.
With CE certificated injection molding machines from 90t-3000t.
