Founded in 1978, Zhongde is a professional cnc machining company focusing on OEM & ODM customized services. Based on 40 years technology deposition, we have developed a one-stop solution from mold designing and rapid prototyping to mass production. Our manufacturing capabilities include plastic injection molding service, compression molding service, CNC machining service, metal stamping service, 3D printing service, custom molding service, overmoulding services, etc.  

 

Zhongde can provide over-molding and insert overmolding to produce unique multi-material parts. Our production materials range from thermoplastic to elastomer-rubber, as well as metal. We've broken down the differences and similarities between the two processes. Let us help you decide which process is right for your project.

 

Both over-molding and insert molding processes involve putting two types of materials together to make one part,also named molding over molding. Overmolding is a two steps process that one to create the substrate and one for the oversold that goes on top of it. Insert molding is a slightly faster process as it takes only one step that the two materials are molded at the same time.

 

Guideline of Overmolding & Insert Molding

 

Insert molding injection is a process where a single part is created using two or more different materials in combination. Traditonally, overmolding starts with injection molding a hard plastic resin that has a higher melting point. Once that part is cooled, another material is injection molded over the first part, resulting in a single, finished product.We also offer injection molding threaded inserts.

 

Insert molding combines metal and plastics into one single part. It allows plastic to bond to insert pieces, mostly brass or stainless steel metal component, which go inside a mold cavity. There are many options for insert that can be placed into the mold. A few of examples are warming labels, threaded bushings, wires, batteries, etc.

Additives of Overmolding & Insert Molding

Name	Description
UV absorbers	Absorb UV radiation, slowing down the degradation of the material when used outdoors.
Flame retardants	Prevent ignition and inhibits spread of fire.
Plasticizers	Increase flexibility and promotes plasticity, reducing brittleness of the material.
Colorants	Used to color plastics.
Carbon fibers	Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle.
Glass fibers	Increase strength, toughness, and rigidity of the material at the expense of making the material more brittle. It is more flexible than carbon fibers.

 

Surface Finishing of Overmolding & Insert Molding

 

Name	Description
Glossy	The mold is smoothed and then polished with a diamond buff, resulting in parts with a mirror-like finish.
Semi-gloss	The mold is smoothed with fine grit sandpaper, resulting in parts with a fine surface finish.
Matte	The mold is smoothed using fine stone powder, removing all machining marks.
Textured finish	The mold is first smoothed with fine stone powder and then sandblasted, resulting in a textured surface.
As-machined finish	The mold is finished to the machinist's discretion. Tool marks may be visible.
