What is the Difference Between a Positive Mold and a Negative Mold in Thermoforming?

Thermoforming is a widely used manufacturing process that shapes heated plastic sheets into functional products by forming them over molds. Central to this process are two primary mold types: positive molds1 (also called male molds) and negative molds2 (also called female molds). These molds differ fundamentally in how they shape the plastic, influencing the design, […]

What Types of Thermoforming Molds Are There?

Thermoforming is a versatile manufacturing process where a plastic sheet is heated to a pliable forming temperature, shaped using a mold, and trimmed to create a usable product. This technique is widely adopted across industries like packaging, automotive, medical, and consumer goods due to its cost-effectiveness and flexibility. The mold is a pivotal element in […]
