Insert Molding

The Process Of Encapsulating A Non-plastic Insert


The purpose is to produce one whole or part. The shaping insert is often a rod or thread, a knife blade, but can also be more complex parts such as a motor or battery.

The main use of the insert is to create a strong and reliable part with a small investment of money and time. It allows manufacturers to increase design flexibility without compromising the structural part.

Cost reduction and quality make insert molding one of the best and least expensive methods, producing light and compact parts that are reliable, durable, and functional. This requires high accuracy to ensure the proper shaping of plastic parts. Even a small mistake can lead to the wrong result. So that quality control procedures are introduced which are very strict. There are also high-quality machines that are precise and can do the job.

Insert Molding

They are precise and reliable in inserting into molds. Folding is a double molding process that consists of molding a plastic layer around and over the previous part. It may seem complicated, but it’s not. A simple component is obtained, which makes one piece of product ready. At least two materials are used, which eventually create one. It is most commonly used for folding. At this time, more recently, some technologies use 3D printing to blend objects from two or more materials.

The coated material is often rubber or thermoplastic. Insert molding has the benefits of saving time and money. The overlap can be used as a double injection process into the sheet metal. The result is chemically bonded in part or the materials are mechanically bonded.
