The general concept behind plastic injection molding service is fairly simple: injecting thermoplastics into a mold that is machined to precise specifications, with the goal of forming the unique features of a part to be manufactured. Molten plastic, which is forced into the mold’s cavity, subsequently cools and hardens according to the configuration of the mold.
However, the number and range of applications—and the many types of plastic injection molding services now available—clearly suggest the innumerable design possibilities injection molding affords. Make that, then, “straight-forward and limitless technology.”
Medical Injection Molding Services
Many components and sub-assemblies for medical devices require precision in the thousandths-of-an-inch range. Medical injection molding is one of the several specialized injection molding services, utilizing plastics specifically approved for use in medical applications. Medical injection molding is vital to the manufacturing of stents, implants, and subcomponents of various complex medical devices.
Micro Molding
Making very small parts for the medical, electronic and other communities where the rule, “the smaller, the better” often applies is termed micro molding. This process requires expert knowledge of resin properties, as plastics molecules are large and behave differently in minute settings than they do in larger applications. Every phase of the plastic injection molding process is increasingly more complex as the size of the desired end product gets smaller.
Overmolding Services
Overmolding involves combining two or more molded plastic or elastomer parts to create a finished product. The first layer is molded, and then the second layer is molded around it. This process allows for only the smallest margins of error and requires superior mold design and high-quality injection equipment for production success.
Insert Molding
With insert molding, metal, ceramic or plastic insert (e.g., a hook, tube or battery) is placed in the mold cavity prior to the injection of molten thermoplastic. This technique requires precision in design and execution in order to ensure repeatability and to produce specification-compliant parts.
An experienced specialist in plastic injection molding service can guide you through the steps of these—or any other—plastic injection molding process, beginning with the concept design, development of a prototype, mold tooling, testing, and design revision, to actual injection molding of the end product.
