CNC Machining Solutions
Insert molding is an injection molding technique that involves injecting a plastic material around a plastic or metal insert (but can also include ceramic or other materials) placed in a mold cavity. The insert is pre-placed in the mold cavity, after which the plastic is injected. These inserts, including threaded metal inserts for enhanced durability, provide specific mechanical or electrical properties to the final product. For example, metal inserts such as aluminum or stainless steel add tensile strength and conductivity, making insert injection molding ideal for highly durable and functional parts. On cooling, this forms a solid part that is strong and durable. Lewei plastic insert molding services allow you to make a strong and permanent bond between the insert and molded plastic.
