Types of Insert Molding Process
Our insert molding capabilities enable us to manufacture insert molded parts with flexible quantity options, from small batches to high volume production.
It is a process that involves injecting multiple plastics and metals into a mold at the same time. These materials then combine to form a stiffer, stronger material. this process can be used to create products with intricate designs. It is commonly used in the automotive industry to create parts that are both strong and lightweight.
It is a type of insert molding that involves the use of multiple materials to create a single product. In this process, the different materials are inserted into the mold one at a time. The operator then waits for each layer to harden before adding the next layer. This process is used to create products with multiple colors or textures.
Insert molding incorporating multiple materials into a single part, creating a strong bond between the insert and the plastic material, resulting in enhanced durability. Additionally, it can provide an attractive, seamless finish and reduce the amount of material required for the finished part, resulting in cost savings.

How Does Insert Molding Work?
Insert Molding Services - (sketch map)
Insert molding is a manufacturing process that involves combining metal or plastic parts with a molded plastic component to create a finished product.
Here is a step-by-step breakdown of how insert molding works:
The key to successful insert molding is creating a strong bond between the insert and the plastic material. This is achieved by carefully selecting the materials and process parameters, such as the temperature, pressure, and injection speed. In some cases, the insert may be coated or treated with an adhesive to improve adhesion to the plastic material.
Insert Molding Plastics
The tooling materials for insert molding depend on the application's production volume, part complexity, and material compatibility.
Tool Steel: P20, H13, S7, NAK80, S136, S136H, 718, 718H, 738
Stainless Steel: 420, NAK80, S136, 316L, 316, 301, 303, 304
Aluminum: 6061, 5052, 7075
Insert molding materials depends on the strength, durability, flexibility, and resistance of the plastic to various environmental factors.
Common plastic materials include:
ABS     Nylon (PA)    PC    PVC
PU       PMMA           PP     PEEK
PE        HDPE            PS     POM
Additives and fibers
To achieve desired properties, additives and fibers can be added to the insert molding material.
Examples of common additives include:
The selection of the insert material depends on the specific requirements of the application, including strength, durability, temperature resistance, and electrical conductivity.
Common inserts materials include:
Notes On Material Selection
Some materials stick together when they are overmolded, while others do not. Perfect combination is the ideal situation.
Since it is overmolded on plastic, the substrate must not deform under the heat and pressure of the molding process.
Most materials of overmolding will have several properties related to tensile strength, elongation, tensile modulus, and so on.
It may be important for your overmoling project to know how much parts can be compressed without permanent damage.
Friction is the force required to cross one surface over another, The surface texture of the mold is a factor too.
Hardness property is the ability of the material to resist indentation, hardness of different materials vary greatly.
The bending resistance of a material is the bending modulus. This attribute is the second factor in the “feel” of materials.
Plaster is affordable, easy to work with, and is used to create both simple and complex molds.
Applications of Overmolding Services
Insert molding is a process of molding plastic around pre-formed components or inserts, such as metal parts, magnets, electronics, or other materials. This technique is used in various industries for different applications.
Advantages of Insert Molding Servcies
When the mold design is inserted with the needed metal, it can quickly help in increasing the stability of the entire product.
Plastic parts can make the overall product very light, and on the other hand, when the inner core metal is combined with the plastic cover, it increases the strength.
Improvement with the size
One can make thinner and smaller products with the same strength and durability and can even get better performance by using insert molding.
The molding production is much more cost-effective. the assembly cost is low, there is minimal labor cost related to the process.
it is a one doesn’t require manual handling and the entire labor-related process. the efficiency of the process gets better.
Variety of materials
You can use numerous materials and even plastic resins in the entire process of insert molding.
Variety of designs
The insert molding technique is used to design different parts and models in numerous industries these days.
Improves the reliability
The reliability of the products produced by the machine used in the process is more significant than all other molding techniques.
Plastic Insert Molding FAQs
A: Plastic Insert Molding is a process used to create components with plastic and metal parts combined. It involves the injection of molten plastic surrounding a pre-made metal insert. Once the plastic cools, it forms around the insert for a finished product that combines both materials’ benefits.
The primary difference between them is that, in overmolding, the plastic material is injected directly onto a molded part or assembly; in insert molding, the plastic is first injected into a cavity and then the finished piece is inserted into another injection-molded part.
A: The insert molding process begins with the creation of a metal insert. This can be done through machining, die casting, or other processes depending on the product’s specifications. The insert is then placed into the injection mold tool before it is closed and secured. Molten plastic is then injected into the mold around the metal part until it cools and solidifies. Once the plastic cools, it is removed from the mold and any necessary finishing is performed before it’s ready to use in product assemblies.
