The history of injection moulding is a fascinating journey from rudimentary beginnings to the sophisticated technology we know today. Here’s a brief overview:

• Early Developments (1870s):
  • The first injection moulding machine was patented in 1872 by John Wesley Hyatt and his brother Isaiah.
  • This early machine was relatively simple, using a plunger to inject plastic into a mould.
  • The Hyatt brothers' invention was primarily used to produce items like buttons and combs.
• Advancements in the 20th Century:
  • The industry saw significant growth in the early 20th century with the development of new plastics like Bakelite.
  • During World War II, injection moulding played a crucial role in producing military equipment and components.
  • After the war, the technology expanded into various consumer goods industries.
• Post-War Innovations:
  • The introduction of thermoplastics in the 1950s revolutionized the industry, allowing for more versatile and efficient production.
  • Screw injection moulding machines were developed, providing better control over the moulding process.
  • Computer-controlled (CNC) machines emerged, enhancing precision and automation.
• Modern Era:
  • Today, injection moulding is a highly advanced process with sophisticated machines and materials.
  • Multi-cavity moulds, robotic automation, and advanced process control systems are common.
  • The industry continues to evolve with innovations in materials, machine design, and sustainable practices.
