Compression molding is one of the oldest molding techniques, with its roots tracing back to the mid-19th century. The process was initially developed for manufacturing products from thermoset materials like shellac, gutta-percha, and early plastics. Here’s a historical overview:

• Early Development (Mid-19th Century):
  • The earliest forms of compression molding were used to produce items like buttons, handles, and electrical insulators.
  • The process involved heating a pre-measured amount of material and compressing it into a mold cavity using a hydraulic press.
• Advancements in Materials (Early 20th Century):
  • The invention of Bakelite, the first synthetic plastic, in 1907, significantly boosted the use of compression molding.
  • Bakelite's ability to be molded into complex shapes and its resistance to heat and electricity made it ideal for various applications.
• Post-World War II Era:
  • Compression molding saw widespread use in the production of automotive parts, household appliances, and electrical components.
  • The development of new thermoset materials, such as phenolic resins and melamine, expanded the range of products that could be manufactured using this technique.
• Modern Developments:
  • While injection molding has become more prevalent for many applications, compression molding remains important for large, complex parts and for materials that are difficult to process using other methods.
  • Modern compression molding machines incorporate advanced control systems and automation to improve efficiency and precision.
• Compression Molding in India:
  • India's manufacturing sector adopted compression molding techniques as it industrialized, particularly in the automotive, electrical, and consumer goods industries.
  • Today, compression molding continues to be a vital process in India, producing a wide range of products for both domestic consumption and export.

Key Milestones:

• 1850s: Early forms of compression molding emerge.
• 1907: Invention of Bakelite drives wider adoption.
• Mid-20th Century: Expansion into automotive and appliance industries.
• Present: Continued use for specialized applications and large parts.

Compression molding's enduring relevance is a testament to its versatility and cost-effectiveness in manufacturing durable products.
