Insert Molding Services

Insert Molding is the process of molding plastic around previously fabricated component(s). Moldtronics Inc, is a pioneer in this field, having produced some of the first parts using this process back in 1957. Since then, we have become experts in the field. This process is compatible with both thermoplastic and thermoset materials.

Overmolding is the molding of plastic over another molded plastic. It is a process that involves molding plastic around or on a previously molded component. The finished part will have extraordinary features such as better durability, improved safety, and increased strength.

Insert Molding Pioneers

Moldtronics Inc. was among the first to develop this technology. We have over 50 years of experience dealing with the complexities of insert and overmolding and delivering turnkey solutions to our customers. As with all molding, early involvement in the design process can yield significant savings in the tooling cost and part price.

History

Moldtronics has literally been around since the beginning stages of insert molding and was a pioneer in this industry. We have a long list of clients and come highly-experienced.

Durability

The largest advantage of insert molding is that it affords enhanced product design and manufacturing. In short, plastic parts with integrated components are much stronger and more reliable.

Efficiency

Because the plastic is formed right over the metal insert, this is essentially a one-step process. We’re able to reduce labor costs which means less time and cost involved.

Final Size

There really isn’t a more precise molding process than insert molding and no other molding process can produce parts as strong and small.

Frequently Asked Questions

What types of materials can be used in insert molding?

Many types of plastics can be used in insert molding for both consumer and industrial applications. These resins are all durable and lightweight and include nylon, polyethylene, polystyrene, epoxy, and elastomers.

Are there design limitations?

Due to its process, the complexity of design in insert molding isn't really possible using metals or other materials.

How is insert molding different from other molding processes?

The main difference between insert molding and other forms of molding is the fact that two different materials are formed into a single piece. This typically leads to a part that is both stronger and lighter while being more cost-efficient.
