Blow molding is a manufacturing process that is used to create hollow plastic parts. It is a form of extrusion-based manufacturing, where a molten tube of plastic, known as a parison, is formed. The parison is then clamped into a mold, and air is blown into it, forcing the plastic to expand and take the shape of the mold cavity. Once the plastic has cooled and solidified, the mold is opened, and the finished part is ejected.
There are several types of blow molding processes, each with its own advantages and applications. The main types include extrusion blow molding, injection blow molding, and stretch blow molding. Extrusion blow molding is the most common method and is used to produce bottles, containers, and other hollow shapes. Injection blow molding is used for small, complex parts, while stretch blow molding is used for producing PET bottles.
Blow molding offers several advantages over other plastic manufacturing methods. It is a relatively low-cost process, especially for high-volume production. It also allows for the production of complex shapes with uniform wall thickness, making it ideal for a wide range of applications. Additionally, blow molding is a continuous process, which means that parts can be produced at a rapid rate.

The overmolding process begins with the selection of two compatible plastic materials that will be used to create the final product. The first material, known as the substrate, forms the base of the part, while the second material, referred to as the overmold, is molded over the substrate to create the desired design and functionality. This combination of materials allows for the creation of products with unique properties and characteristics.
The overmolding process typically involves the use of specialized injection molding equipment and molds designed to accommodate the two materials. The substrate material is first molded into the desired shape, and then the overmold material is injected over the substrate to create the final overmolded part. This process requires precision and expertise to ensure proper adhesion and integration of the two materials.
Overmolding offers several advantages in plastics manufacturing, including improved product durability, enhanced design flexibility, and the ability to incorporate multiple materials into a single part. By overmolding different materials, manufacturers can create products with varying textures, colors, and functional features, resulting in more appealing and versatile end products.
Additionally, overmolding allows for the creation of products with soft-touch grips, ergonomic handles, and integrated seals, gaskets, and inserts. This process also reduces the need for secondary assembly processes, as multiple components can be combined into a single overmolded part, streamlining production and reducing overall manufacturing costs.
