MOKO Insert Molding

Insert molding is one of the most effective molding techniques, which can combine metals and plastics together into a molded part firmly and perfectly. It is much popular and widely used for many applications such as encapsulated electronic devices, threaded fasteners, medical equipment and so on. MOKO Technology has been working on it for over a decade, we offer one-stop insert molding solutions, ranging from designing to manufacturing, finishing and after-sales services. We specialize in molding products, not only for insert molding, but also for conventional molding, over-molding and injection molding, etc.

How Does Insert Molding Work?

The insert molding process is roughly the same as the production steps of traditional injection molding, the main difference is that the metal part would be placed in the mold at the specific position first for insert molding, and the method of inserting metal parts can both be a manual and automatic way. The following lists each step of the whole  process:

The first step, insert the metal part into the mold in the correct position. For production with low volumes, we can use manual insertion, but please note that manual insertion has the limitation of metal sizes. Normally, the operators need to wear gloves as the high mold temperature, which would bring inconvenience to operation, especially when the metal parts are tiny. While for automatic insertion, it has high accuracy, consistency and efficiency. But we should aware that the initial cost for an automatic process is much higher, so we should choose one method that is most cost-effective.

Second, the molten plastic material would be injected into the mold, and cover the metal part completely when it solidifies, making sure that these metal and plastic components can be adhesive firmly and perfectly.

The last step, remove the well-encapsulated components from the mold after cooling.

The Advantages of Insert Molding

Smaller Product Sizes

Compared with assembly parts, insert molded products has smaller sizes as the metal part is located inside, which means the size of the whole product can keep the same even equipped with metal components. On the other hand, the insert molding process can manufacture smaller and thinner components while the performance will not be affected.

Lower Costs

There is no need to assemble parts, no welding or other secondary process required for insert molding, only the metal part insertion may require the manual operation, which can reduce assembly and labor cost largely. In addition, some economical materials such as resins are workable for it, so that the whole cost can be lowered.

Less Error

The process involves a few steps and it is highly automatic, which reduces the possibility of making errors. The whole process is well-designed and the robots guarantee the high accuracy of products.

More Material Options

There are a variety of materials that can be used for insert molding, for example, thermoplastic materials like polyethylene, polystyrene, and nylon, which are recyclable, light and durable. In addition, materials like epoxy and rubber are also workable for inset molding.

Design Flexibility

Insert molding can make the designing job easier, as the engineers needn’t think about how to design the assembled parts. On the other hand, it can fabricate components with various shapes and materials, which will not limit the design ideas and can expand possibilities of making different molded parts for different industries.
