The actual "overmolding" is a kind of secondary injection molding, the product generally includes the main body (hardplastic) part and the outercover (softplastic) part.
In the mold manufacturing, the main body of the hardpart will be manufactured first, the main part of the mold design according to the normal design procedures, the outercover (softplastic) part of the mold design to the hard rubber finished products as a reference, no need to put shrinkage, and in the mold cavity, the main body of the hardpart needs to maintain consistency, the moldcoreis the shape ofovermolding part.
In production, you need to first produce the main body of hard part, and then put the main body of hard part into the overmolding mold to do injection production.
Overmolding injection molding allows for flexible designs as it offers the advantage of creating multi-material parts. This means that designers can choose different rigid or soft materials to produce products with varied textures and functionality, depending on the application.
The process of overmolding injection molding offers superior adhesion and bonding properties, ensuring a stronger and long-lasting product. This extends the product's lifespan and leads to its increased durability, making it a preferred choice for many industries.
Overmolding injection molding offers better performance than other injection molding processes. The combination of different materials makes the final product more efficient and functional.
Overmolding injection molding is a fast and cost-effective method, particularly when creating high-volume parts. The process minimizes the risk of material waste, which makes it a considerable investment in high-volume production runs.
Overmolding injection molding provides a better aesthetic appearance to the products than conventional injection molding. This means that the final product looks more visually attractive, which can significantly improve the product's market appeal.
Overmolding injection molding can reduce assembly costs by combining two or more previously separate parts into a single, integrated product.
There are different types of overmolding processes, each of which has different applications. Here are some of the most common types of overmolding structures:
