Fox Mold's metal insert molding is an advanced manufacturing process that combines the strength and durability of metal components with the versatility of plastic. This technique involves inserting a preformed metal part, such as a screw, nut, or custom-shaped component, into the mold cavity before injecting the molten plastic. The result is a single, integrated parts with enhanced mechanical properties, such as wear resistance, increased strength and thermal conductivity.
Unlike over-molding, insert molding could be done for one time. The plastic is injected into a mold where an insert has been placed in advance.
Insert molding is more convenient method for parts with threaded holes. Numerous clients have received excellent results from our insert molding solutions.
There are two types of hardware rubber coating processes:
The first one ne is full coverage rubber coating, which is to cover the metal insert completely, and the metal insert do not expose the coating layer after molding . To ensure that there is no leakage, no displacement, and no movement;
The second one is metal insert partial covered by plastic coating, which has a much larger application. Customized molds are made according to drawings, and then the metal insert are partially coated. This can also enhance the structural strength, while meeting more requirements such as insulation, conductivity, shock absorption, and waterproofing.
The most parts we done is IGBT Module prototype mold and low volume production.
The Metal insert molding parts has the following advantages:
2) Moisture-proof and mildew proof: rubber/plastic has the characteristics of waterproof, moisture-proof and mildew proof, which can maintain the surface of hardware to a certain extent.
3) Good comfort: After the hardware is coated with rubber, it can not only increase the feel, also reduce the sense of friction when the hardware is used, which is more comfortable.
Why Choose Metal Insert Injection Molding
1. Compatible with multiple materials
Injection molding with metal inserts can combine different materials into one component. For example, metals, plastics, and even electronic components can be safely encapsulated in plastic materials.
2. Enhanced structural integrity
The insert molding process creates a strong and lasting bond between the plastic material and the insert, which enhances the structural integrity of the final product. This is especially beneficial for parts that are subject to mechanical stress.
3. Reduced assembly steps
Metal insert injection molding can eliminate or reduce additional assembly steps because it allows multiple components, such as metal or plastic inserts, to be integrated into a single molded part. This simplifies the manufacturing process and reduces labor costs.
4. Cost-effective production
Although the initial tooling and setup costs are higher, insert molding can achieve cost-effectiveness in the long run by reducing assembly time and minimizing the need for secondary operations. The integrated manufacturing process often saves overall costs.
5. Reduced weight
By adopting lightweight materials as insert molded parts, metal insert molding can produce lighter components without compromising strength. This is very important in applications where weight is a critical factor, such as the automotive and aerospace industries.
6. Precision and consistency
Metal insert molding allows for precise control of insert placement, ensuring consistency and accuracy in the final product. This is critical for applications that require tight tolerances and precision.
1.Consumer Electronics
Manufacturers in the consumer electronics industry often use insert molding to avoid the use of fasteners and solder in the manufacturing process. Typical examples of insert molded parts in this industry are digital control panels, appliance knobs, components, and wires covered with rubber on the outside.
2.Medical Devices
Before choosing insert molding to manufacture devices and products such as medical implants, make sure the plastic is biocompatible.
3.Aerospace
Suitable for making handheld devices such as screwdrivers, scissors, dials, knobs, etc.
4.Automotive
Automotive manufacturers produce insert molded parts as an alternative to metal parts. These plastic insert molded parts are more durable and lighter. Threaded fasteners, gears, and electrical sensors are common insert molded parts in the automotive industry.
Insert injection molding is particularly useful in industries requiring high-performance parts, such as automotive, electronics, and aerospace. Fox Mold's expertise ensures precise alignment and strong bonding between the metal and plastic, providing reliable and durable solutions. This process not only improves product performance but also reduces assembly time and costs, making it a preferred choice for complex and demanding applications.
