Custom Insert Molding Service

Create Your Unique Molded Parts Within Weeks

Custom Insert Molding Service

Ruitai provides you with custom insert molding service from prototyping to high-volume production up to 10000+ pieces.

To offer you complete insert molding solutions, we have become a fully equipped manufacturer. Our capabilities cover: EDM machining, CNC machining, injection molding, grinding, etc.

Typically, we use aluminum for rapid tooling to create custom parts. The shortest time we need on finishing one molding project is around half a month.

 

Low-volume Prototyping

Not only can we make plastic moldings, but we can also create metal insert prototypes through CNC machining and sheet metal fabrication.

Insert Injection Molding

Insert injection molding is one of the production methods commonly used to make high-accuracy plastic parts, and we can create molded parts ranging from 500 to more than 10,000 pieces.

Rapid Tooling

Rapid tooling is an important preparation part of plastic injection molding, which can produce high-precision metal molds in a short time.

Advantages of Insert Molding

As one type of injection molding, insert molding can be combined into a stronger component by combining plastic and metal inserts. The inserts are often threads and bars. There are some advantages of insert molding for your reference:

1. No Assembly Required. We just put the metal insert into the mold before injecting the material, and the plastic forms the part directly on top of the metal insert without assembly.

2. Stronger. Because insert molding completes the machining of the entire part in one go, rather than assembling it in one step, insert molded parts are stronger.

3. Longer Life-span. The combination of metal and plastic reduces wear on the plastic, while the plastic part protects the metal insert from corrosion.

FAQ:

What Is Insert Molding and Overmolding?

Injection molding is a popular fabrication technique to create repeatable plastic parts for mass production. Its process mainly refers to 4 steps: melting, injection, cooling, and ejection. It is considered one of the most economical ways to create plastic products within a short production circle. Insert Molding and Overmolding belong to two variants of injection molding. There are still some differences between them.

Banner-Overmolding VS Insert Molding

Insert molding: It uses the metal inset as the substrate of the plastic part. We usually put the metal insert manually into the mold before injecting the melted plastic. After closing the mold, an insert molded part is done on it. The common application of insert molding includes fasteners. The metal inserts protect the parts from damaging the thread. The finished insert molded parts are both durable and lightweight.

Overmolding: It is similar to insert molding. We can produce a solid plastic part first by injection molding. After that, we will put it into the second mold as a substrate. Then, we will create a softer layer of plastic parts on it. Compared to insert molding, it takes a longer time to create custom molded parts by overmolding. The combination of solid and soft plastics can increase the grip of the molded parts. For example, the handles of toothbrushes and electric drills.
