About Injection Molding
Injection molding is a high-efficiency manufacturing process that produces identical plastic parts at scale. It works by heating thermoplastic pellets until molten (typically 200–300°C), then injecting the material under high pressure (500–2,000 bar) into a precision-machined steel or aluminum mold cavity. The plastic cools and solidifies in seconds (cycle times range from 10–120 seconds), taking the shape of the mold. Once ejected, the part is complete – requiring minimal finishing.
This process excels at creating complex geometries with features like thin walls (as low as 0.3mm), living hinges, textured surfaces, and integrated fasteners. Key technical advantages include:
Common applications span medical devices, automotive components, consumer electronics, and packaging – virtually any plastic item used daily likely involved injection molding.
