Customize Insert Molds for Your Applications

Insert molds are used in the following industries:

Medical

Medical equipment like syringes and drug holding compartments are made using insert molds to create identical products of the same size, an important factor that determines the efficacy of the equipment

Automotive

There are parts of the car that are made of plastic, like headlight covers. Insert molding is the only way they can attain the right shape and size that fits in with the rest of the car parts.

Consumer Products

Consumer products require the best packaging materials, which are made using insert molds for uniformity and safety purposes.

Electronic Components

Electrical components like wires require insulation that protects people from electrical shock. Insert molding is the most effective way of ensuring that this is achieved.

Insert Molding Process

Molten plastic is injected into a pre-made mold that takes the shape of the intended final product in the exact replica. The mold is then allowed to cool, refined until it attains the shape and looks needed for it to function.
Insert molding process comes in handy in the assembly of discrete parts that can be joined to make complete components that can be utilized in many ways depending on the needs. Rather than create a huge singular component, you can join smaller and more refined parts made from the insert molding process to create a better product.

The biggest beneficiaries of the insert molding process are the electronic industry, car assembly, among many others.

High-Quality Thermoplastics for Insert Molding

The raw materials used in the insert molding processes are called thermoplastics. They can be reheated repeatedly, cooled, and softened without losing any of their string qualities. The quality of the final products depends on the quality of the thermoplastics used. Thermoplastics come in many forms and colors, with each designed for a specific product type.

When choosing thermoplastics for this process, you have to pay attention to the following considerations.

Advantages of Insert Molding

Insert molding allows us to mold one plastic material into or around another material (normally metal) in an injection process to obtain the desired performance to weight combination. A common example of insert molded products is a plastic part with embedded metal nut for screw or bolt assembly.

Applications of Insert Molds

Case Study

Wire Plug

October 13, 2018. Our European customers send us the RFQ to make one set of injection mold for the plug with cable, which was applied in the automotive electronics. They have made one mold for this product in 2016, they need a new mold and want to make some structural improvements. Before this, KI was not so familiar with this type of mold, but we were confident that we can fulfill our customer’s requirement.
