 Over molding is a transformative process in manufacturing, where two or more materials are used to create a single composite part. This technique involves molding one material over another previously molded part, effectively enhancing the final product's functionality, aesthetics, and durability. The choice of materials plays a crucial role in determining the performance and quality of the manufactured item. By selecting suitable materials, manufacturers can ensure that the product meets specific requirements such as increased strength, improved comfort, or enhanced aesthetic appeal. This blog will explore the typical materials used in over-molding, focusing on their properties, applications, and the strategic benefits they bring to different industries. Understanding the fundamentals of material selection in over-molding can lead to more innovative and successful product designs, whether for protective cases, soft-touch handles, or multi-material instruments. Common Base Material

 Plastic injection molding produces plastic parts by injecting molten plastic into a mold cavity. In two-shot molding, two different plastics are injected in sequence into one mold to create a two-material or two-color part. Multi-shot molding injects three or more plastic shots into a single mold to create parts with multiple materials or colors. Overmolding involves injecting one material onto a pre-molded part already placed in the mold, combining two materials into one part. Multi-shot and overmolding combine different properties like flexibility, strength, and texture into one part. They increase design freedom but require more complex tooling than standard injection molding. Injection Molding Injection molding is a typical manufacturing process for producing plastic parts in high volumes. The primary plastic injection molding process involves melting plastic material into liquid and injecting it under high pressure into a mold cavity. The plastic cools and solidifies inside the

  Custom Injection molding Service Custom injection molding is the process of producing plastic, metal, or ceramic parts by injecting molten plastic material, metal powders, or ceramic powders into a mold that has been custom-made to the specifications of a unique part design. Unlike standard, off-the-shelf injection molds, custom molds are engineered and machined to precisely match each new plastic part's required shape, size, geometries, features, and tolerances.  Neway mainly provides the following three kinds of custom injection molding services: Metal Injection Molding (MIM) Service Metal injection molding service :  Metal injection molding is a versatile manufacturing process that allows the high-volume production of complex, high-precision metal parts. Some of the main benefits of MIM include the ability to produce small, intricate geometries that are difficult with other methods; producing near-net-shape parts to tight tolerances of ±0.3% while minimizing material waste; a
