Inspiration
In 1868, Hayate developed celluloid, refined by Alexander Parkes in the 1850s. Hayate improved celluloid to be processable into finished shapes. In 1872, Hayate and his brother patented the first piston injection machine. By 1946, James Watson Hendry created the first injection molding machine enhancing speed and quality control. In the 1970s, Hendry continued to innovate, developing the first gas-assisted injection molding process, leading to improved production of complex, hollow products.
What it does
Plastic injection involves shaping the material by injecting molten raw material into a mold, solidifying it, and making it ready for use. The machine responsible for this operation is the plastic injection molding machine. There are horizontal and vertical plastic injection machines, categorized by energy types: hydraulic, electric, and hybrid machines. Hydraulic machines were the only option until 1983 when 'Nissei' introduced a fully electric plastic injection molding machine. Electric machines aimed to save energy and eliminate problems associated with hydraulics. However, their higher cost deterred some manufacturers despite offering greater precision.
Hybrid injection machines combine the best features of hydraulic and electric systems, aiming for lower cost and higher accuracy. However, the expected significant difference in energy consumption has not materialized.
How I built it
The Plastic Injection Machine comprises three main units: Injection, Clamping, and Control. During operation, plastic material is melted, injected into a mold, and solidified to create a finished product. Key components include the injection unit (melting and injecting plastic), clamping unit (holding the mold closed), and control unit (coordinating the process). The machine's design allows for precise, repeatable production of high-quality plastic parts
