Insert Molding

INSERT MOLDING—PLASTIC INJECTION MOLDING

What is insert molding

Insert molding is the plastic injection molding process where one material (usually like a metal insert ) is molded onto a second material (typically a rigid plastic, Like ABS or PC, or Nylon). In some cases, inserts can be as complex as pipes or motors.

The plastic is injected into the mold cavity, which contains a pre-placed insert. The result is a single molded plastic piece surrounded by plastic inserts. It is used in many industries.

The process of insert molding begins when some form of the insert is placed in the mold. The insert could be any type of fastener, nut, connector or object that historically required soldering. Plastic is injected into the mold, encasing the inserts and forming the part.

Insert Molding Uses

It is an ideal choice for improving the functionality and reliability of the overall product and is free from welding, assembly, and bonding.
The need for secondary operations can help save production costs, improve product quality and production time.

Regardless of the design requirements of any of your injection products, our insert molding quality is already in every possible environment test. We provide plastic molding services to customers in almost every industry, including:

• Automotive industry
• Medical accessories
• Precision Electronics
• Consumer goods

Why customer need to insert molding 

Insert molding adds incalculable value to customers. By improving the end-user experience in comfort, operability, and Ergonomics.

In order to achieve this level of manufacturing, there are two important concepts that must be successful.
We have to understand the market that customers have won and is the cornerstone of our long-term cooperation with customers.

1. Product Design: General Concepts. The wall thickness of the substrate should be as uniform as possible to obtain the best cycle time.
2. Material selection is important: Materials used in our process are synthetic polymer compounds that are used in place of plastic and rubber due to their superior properties.   Polyurethane, epoxy, acrylic, silicone, and RIM  (reaction injection molding) polyurethane have excellent dielectric properties and are available in hundreds of custom formulas that have been designed for use in a wide range of specific applications.

CNMOULDING will continue to have a world-class quality management level, consistently providing the most critical plastic injection parts and components.

Overmolding Vs Insert molding

On the surface, the two technologies look very similar. Sometimes even we in the industry see them as a kind of technology. Basically a component in plastic resin such as a threaded liner. Plastic injection molds create objects, injection molding plastic is forced into the mold cavity. They are often used to scale manufacturing operations, creating new products, such as toys, kitchen utensils, caps, mobile phone sets. You can use the injection mold“flash line” extra plastic around the seams’ discovery projects.
