What is insert molding?
Insert plastic is the most common and widely used process that is used ,Insert molding is a process in which plastic is injected into a mold that contains an pre-placed insert. The result of insert molding is a single molded plastic piece with an insert surrounded by the plastic. Inserts can be made of metals or different types of plastic. Insert molding is used in many industries. Applications of insert molding include insert-molded couplings, threaded fasteners, filters, and electrical components.

What Makes Insert Molding Different from Injection Molding and Overmolding?
     ----Insert injection molding is often compared to other molding methods like injection molding and overmolding, but there are some differences between each of the processes. Injection molding involves injecting one or more molten plastic resins into a mold to create a single finished part.
     ----Overmolding is a two-step process where a plastic layer is molded over and around a previously molded part to produce a single component; an adhesive is sometimes required to create a permanent bond. Insert molding is similar to overmolding in that it involves joining separate parts to form a single component. The difference, however, is that plastic insert molding is a single-step process where the preformed insert and molten resin are placed in a mold together to combine two parts.
     ----Generally, insert molding is the process of choice when annual production volumes and local labor costs are low. For higher volume production programs (over 250,000 units annually) or areas withincreased labor costs, multi-shot molding operations are the method of choice.

Why chose Insert Molding?
There are several reasons to choose insert molding:
     ----It reduces the post-molding assembly required with separate metal elements, which can be costly. Separate installation of these components adds motion waste, increases production time, and involves additional equipment and labor. Insert molding saves those assembly and labor costs.
     ----It enables designers to integrate features into plastic parts that will make them stronger, more durable, and more reliable than native plastic areas. For example, installed metal compression limiters will strengthen fastening areas and eliminate creep potential.
     ----It allows enhanced product design by integrating features not possible with plastic alone: for example, a stainless steel screen insert can provide a filtration area in a plastic part.
     ----It is useful in metal to plastic conversion to make parts more efficient. There is increasing demand across industries to produce parts in plastic instead of metal - to lower weight, reduce production costs, and eliminate corrosion. Insert molding allows retention of essential metal elements within a plastic part. 
Insert Molding apply in Industries Applications
Many industries can benefit from insert molding, such as:
     ----Automotive and Trucking: Metal to plastic conversion parts reduce weight and improve fuel economy
     ----Medical: Plastic parts with metal components are used in a wide range of medical and surgical devices
     ----Consumer Products: Insert molding has applications in an array of industries from electronics to HVAC systems
     ----Aerospace: Insert molding is used for parts for aircraft interiors, controls, communications and guidance/navigation.
Insert molding provides you with the best of both worlds: it retains the strength and functionality of metal parts by embedding those elements into a more economical and efficient
How do you support the insert in insert molding?
The inserts used for plastic insert molding are typically made from brass, steel or stainless steel and have a threaded surface to provide better adhesion to the plastic. Injection molding inserts and are placed in the mold either by hand or by machine with the mold in a vertical position. This positioning allows gravity to keep the insert in place as the mold is closed. As the molten plastic resin is slowly poured into mold, it helps hold the insert in a fixed position.

Insert Injection Molding Benefits
Metal inserts and bushings are commonly used for reinforcing the mechanical properties of the plastic parts or thermoplastic elastomer products that are created through the insert injection molding process. Insert molding provides a number of benefits that will improve your company's processes all the way down to its bottom line. Some of the benefits of insert injection molding, include:
•Improves component reliability
•Improved strength & structure
•Reduces assembly and labor costs
•Reduces the size & weight of the part
•Enhanced design flexibility
