What is plastic injection molding?
Plastic injection molding is a manufacturing process in which molten plastic is injected into a mold cavity under high pressure. The plastic solidifies and takes the shape of the mold, creating a part. This method is ideal for producing high-volume, durable, and intricate parts with tight tolerances, making it widely used in industries such as automotive, medical, and electronics.
How long does plastic injection molding take?
The time required for plastic injection molding depends on several factors, including part complexity, mold design, and production volume. For high-volume runs, parts can be produced in seconds or minutes per cycle. For custom or complex parts, the process may take longer due to additional mold creation and testing. Overall, injection molding is an efficient process for large-scale production.
