Different Types Of Overmolding Processes
There are different types of overmolding processes, each of which has different applications. Here are some of the most common types of overmolding structures:
Plastic Over Plastic
This involves the molding of a rigid plastic material, which is later overmolded with another rigid plastic. These plastics can be of different colors, structures, and resins.
Rubber Over Plastic
This involves the molding of a rigid plastic material. Once molded, this plastic is then overmolded with soft rubber or TPE.
Plastic Over Metal
First, a metal substrate is machined, cast, or formed. Then, it is inserted into an injection molding tool, and the plastic is molded over or around the metal.
Rubber Over Metal
First, a metal substrate is machined, cast, or formed. Then it is inserted into an injection molding tool, and the rubber or TPE is molded over or around the metal.

What is Overmolding?
Overmolding refers to the manufacturing process of a single part, which is created using two or more different materials in combination with each other. Typically the first material, sometimes called the substrate, is partially or fully covered by subsequent materials, sometimes called the overmold materials, during the manufacturing process. It is when one thermoplastic material is molded over another material to form one integrated part of high-quality and better resistance.
Benefits of Overmolding
Cost-Efficiency
Once the mold is created, it can be used repeatedly to create as many parts as possible, making it highly economical. Moreover, overmolding also reduces assembly and labor costs.
Reliability
It eliminates the need for the bonding step in the manufacturing process, giving a boost to reliability and consistency.
Enhanced Strength
With double strength of two molded parts, the manufactured part has higher durability and a more solid structure.
Accuracy & Efficiency
In higher volumes, overmolded parts preserve a higher precision and less waste than other manufacturing processes.
Flexibility
Custom overmolding allows the production of parts in multiple thermoplastic materials as required by your project and its application.
Better Surface Quality
Improve the aesthetic, strength, and functionality of the components with a combination of different colors and hardness.
PREGUNTAS FRECUENTES
Overmolding is a multi-shot injection molding process that produces a single product from two or more different thermoplastics.
The first “shot” is called the substrate, which is typically the more rigid of the two materials being used and is designed to accept the subsequent shots or overmolds.
Where the substrate is the first material injected into the mold, the overmold is the second. The substrate is designed to accept the overmold onto or around itself. The substrate is typically more rigid than the overmold.
Overmolding refers to the process when plastic is molded over another molded part. The first component is made inside an injection mold, and it is then placed into a second mold to add the over-molded material. On the contrary, Insert molding refers to combining other parts, particularly metal parts, directly into the injection-molded product.
Depending on size and complexity, we take from 4 to 12 weeks generally to complete an overmold project.
