Question

Quizplus · Accepted Answer

Blow molding is a manufacturing process in which hot plastic is blown into a mold cavity to form a hollow part. The plastic is heated until it melts and then blown into a mold where it cools and hardens into the desired shape. The shape of the mold determines the shape of the final product, and the blowing process ensures that the plastic is evenly distributed throughout the mold.
