10M ago
What is a plastic hinge? In injection molding, a plastic hinge refers to a specialized feature designed within a plastic part to provide flexibility and allow rotational movement. The plastic hinge design allows it to endure repeated cycles of bending or flexing without causing permanent deformation or failure of the part. Using the inherent elasticity and flexibility of certain plastic materials, such as polypropylene or polyethylene, plastic hinges allow for rotation within a part without inserting another material. This functional and cost-effective mechanism within injection-molded product ..read more

1y ago
Plastic injection molding is a process in which molten plastic injects into a mold cavity, then it cools down until a solid part forms in the shape of the mold. There are many factors that make that process specific for each part, and one factor to consider is how many cavities a mold uses. H2: What is a mold cavity? An injection molding cavity is the space that is hollow in an injection mold in the shape of a plastic product. Designing the mold is one of the first steps to creating an injection molded plastic part. When designing the mold cavity, there are several factors to account for, incl ..read more
