Today, we provide you with an overview of the history of Plastic Injection Molding. Its use dates to the late 19th century and has evolved through several key milestones:
1872 – Invention of the First Injection Molding Machine: American inventors John Wesley Hyatt and his brother Isaiah Hyatt developed the first injection molding machine.
1903 – Invention of Bakelite: Belgian chemist Leo Baekeland developed Bakelite, the first fully synthetic plastic, marking a turning point by enabling more durable and heat-resistant molded products.
1940s – Wartime Expansion: World War II drove innovation and mass production of plastic parts for military use, significantly advancing molding technologies and materials like nylon.
1956 – Introduction of the Screw Injection Machine: James Watson Hendry developed the first screw-type injection molding machine, which offered better control over injection speed and pressure.
1970s–1980s – CAD Integration: The rise of computer-aided design (CAD) and automation transformed mold design and manufacturing, improving precision and reducing development time.
1990s–Present –Materials Advancements: Innovation has led to high-performance thermoplastics, micro-molding, multi-shot molding, and efforts to develop biodegradable and recycled plastic materials to address environmental concerns.
Sustainability and Material Recycling: Concern over environmental impact has led to use of recycled plastics, better mold designs to reduce waste, energy efficient machines (all electric), biodegradable, or bio-based plastics.
Micro Molding, Multi Shot Molding, Overmolding, Insert Molding: More complex molded parts, multiple materials injected sequentially or simultaneously.
