What Is Injection Molding?
Injection molding is a manufacturing process where molten plastic is injected into a mold to create parts and products with precise shapes and dimensions. It’s commonly used for mass production of identical items, from small components to large industrial parts. The process involves heating raw plastic material until it liquefies, then injecting it into a custom-designed mold under high pressure. Once the material cools and solidifies, the finished part is ejected. Injection molding is known for its efficiency, ability to produce complex designs, and cost-effectiveness for large production runs across various industries like automotive, electronics, and consumer goods
