Choosing the wrong custom mold manufacturer can lead to unexpected tooling costs, production delays, and inconsistent plastic part quality. For OEM companies and industrial buyers, even small mistakes during supplier selection can create expensive problems after mold manufacturing begins. WIT Mold has specialized in manufacturing custom plastic molds since 2011, supporting customers with tooling design, […]

Complex plastic components often contain internal undercuts, retaining grooves, or threaded features that cannot be released using a conventional fixed mold core. These geometries create demolding challenges, particularly for rigid plastic parts that cannot be safely stripped from the tool. Collapse core molds address these challenges by using a segmented core that contracts inward before […]

Manufacturing large plastic components requires suitable structural strength, dimensional stability, and manageable production costs. Conventional injection molding can present challenges when producing thick-walled parts, large housings, and components with integrated supporting features. Structural foam molding offers an alternative by creating plastic parts with a cellular core and a relatively dense outer skin. This structure can […]

Mold lifetime is one of the most important factors affecting production efficiency and overall manufacturing costs. A mold with longer service life can help reduce replacement frequency, minimize downtime, and maintain stable product quality during mass production. However, long mold lifetime is not achieved by chance. It requires continuous quality control throughout the entire process, […]

In custom injection mold manufacturing, mold design is one of the most important stages before steel cutting begins. A good mold design affects machining accuracy, assembly efficiency, trial results, molding stability, maintenance convenience, and the final plastic part quality. At WIT MOLD, mold design is not only based on software operation. It also depends on […]
