What type of manufacturing process utilizes intense pressure to hold molds together while injecting melted resin?

The manufacturing process that utilizes intense pressure to hold molds together while injecting melted resin is injection molding. This process involves heating thermoplastic materials to a molten state and then injecting them into a mold under high pressure. This high pressure ensures that the molten resin fills the entire cavity of the mold, allowing for the precise shaping of complex designs. Once the resin cools and solidifies, the mold can be opened to reveal the finished product.

Injection molding is widely used for producing a vast array of items, from small components to large parts, due to its efficiency and ability to create high accuracy and repeatability in the molded parts. The mold generally consists of two halves tightly held together to prevent any leakage of the resin during the injection process, ensuring a clean and detailed final product.
