Are you confused about which type of plastic injection molding is best for your business needs? Do you often struggle to choose the right molding method, or are you unsure about the different product categories and their applications? Are you finding it difficult to determine which materials and grades of plastic will meet your quality and performance standards? If these questions sound familiar, keep reading to explore the different types of plastic injection molding and how you can make an informed decision for your business.
Common Types Of Plastic Injection Molding
There are several different types of plastic injection molding used in manufacturing processes today. Understanding the differences is key to selecting the right method for your needs. Below are the most common types:
1. Standard Plastic Injection Molding: This is the most common method used for mass production of plastic parts. It involves injecting molten plastic into a mold under high pressure to form the desired shape.
2. Two-Shot Injection Molding: This process uses two separate injection cycles to create a multi-material or multi-color part. It’s ideal for parts that require both rigid and flexible components or different colors in one mold.
3. Gas-Assisted Injection Molding: This process uses gas to create hollow cavities within the molded parts. It’s ideal for lightweight parts and can help reduce the use of materials, making it a more cost-effective solution.
4. Injection Molding with Insert Molding: This technique involves placing metal or other materials into the mold before injection.
The molten plastic then surrounds the insert, forming a bonded product. This method is commonly used for creating parts that require metal components embedded in plastic.
5. Micro Injection Molding: As the name suggests, this method is used for producing very small, precise parts. It’s typically used in the medical, electronics, and precision engineering industries.
FCE’s Plastic Injection Molding Categories
FCE offers a variety of injection molding solutions tailored to meet the diverse needs of businesses in different industries. Below are some of the key types of injection molding processes that FCE specializes in:
1. Custom Plastic Injection Molding
FCE provides custom plastic injection molding services for clients with specific, tailored needs. This service is ideal for companies that require unique designs, materials, or sizes for their products. Whether you need low or high-volume production, FCE offers a comprehensive solution from prototype design to mass production, ensuring that your custom parts meet exact specifications.
2. Overmolding
We also specialize in overmolding, a process where multiple layers of material are molded over an existing part. This process can involve combining different materials, such as soft plastics with rigid components, or using multiple colors. Overmolding is widely used in applications that require components with both hard and soft materials in a single part, such as in automotive, medical, or consumer electronics products.
3. Insert Molding
FCE’s insert molding process involves placing metal or other materials into the mold before injecting plastic. The molten plastic then surrounds the insert to form a durable, integrated part. This process is particularly useful for creating components such as automotive connectors, electrical parts, and mechanical components that require metal inserts for enhanced strength and conductivity.
4. Gas-Assisted Injection Molding
Gas-assisted injection molding utilizes gas to create hollow spaces within the molded parts. This process is ideal for producing lightweight components while reducing the amount of plastic used, making it a cost-effective solution for industries like automotive and electronics. Gas-assisted molding allows for the creation of complex geometries and parts with lower material consumption, improving overall efficiency.
5. Liquid Silicone Rubber (LSR) Injection Molding
We offers liquid silicone rubber (LSR) injection molding, a process used for creating highly flexible, durable, and heat-resistant parts. LSR molding is commonly used in the medical, electronics, and automotive industries to produce parts such as seals, gaskets, and flexible housings. This technique ensures the production of precision parts with high reliability and excellent material properties.
6. Metal Injection Molding (MIM)
FCE’s metal injection molding (MIM) combines the benefits of both plastic injection molding and powder metallurgy. This process allows for the production of complex metal parts at a high rate of precision and low cost. MIM is often used in industries that require small, complex metal components, such as automotive and electronics, where the parts must be strong, durable, and cost-effective.
7. Reaction Injection Molding (RIM)
Reaction injection molding (RIM) is a process that involves the injection of two or more reactive materials into a mold, where they chemically react to form a solid part. This process is commonly used for producing large, durable parts such as automotive body panels and industrial components. The RIM process is ideal for parts that require low pressure during molding but must exhibit excellent mechanical properties and surface finishes.

The Advantages of Plastic Injection Molding
Plastic injection molding offers several key advantages that make it a popular choice in manufacturing. Below are the general benefits, followed by specific advantages offered by common and branded products:
1. Cost-Effective for High Volume
Plastic injection molding is one of the most cost-effective methods for producing large quantities of identical parts.
Industry data shows that the per-unit cost of producing 100,000 parts using injection molding is significantly lower than other manufacturing methods, especially once the molds are created.
In high-volume production, the efficiency and low cost of injection molding become particularly evident.
2. Precision and Consistency
This method offers high precision, making it ideal for parts requiring tight tolerances. Data shows that injection molding can achieve part tolerances as tight as ±0.01 mm, which is crucial for industries like automotive and electronics, where each part must meet the same specifications to ensure product consistency.
3. Versatility
Plastic injection molding can be used for a wide range of materials, including different types of plastics, resins, and composites.
This allows manufacturers to choose the best material for the application, whether it’s strength, flexibility, or heat resistance. FCE’s molding solutions support up to 30 different material types, meeting diverse customer needs for various performance requirements.
4. Enhanced Material Properties
With advancements in molding technology, it’s now possible to achieve improved material properties, such as better tensile strength and wear resistance, particularly in multi-shot and insert molding.
Multi-shot molding products, for example, enhance part strength while optimizing material usage and reducing waste.
5. Speed of Production
Injection molding is faster than many other manufacturing methods, especially in high-volume production.
Standard injection molding can produce parts in as little as 20 seconds each, while multi-shot and insert molding can complete complex parts in just a few minutes. This significantly shortens production cycles and accelerates time-to-market.
