3D Printing - Functional Prototyping Solutions - Simulating Overmolding

PolyJet 3D Printing technology has modernized product design with the capability to jet two or more materials simultaneously to create prototypes with ready–printed overmolded parts.

Overmolding is a molding process in which two or more materials are combined to produce one part. An overmolded part begins with the molding of a rigid, thermoplastic substrate. On top of the substrate, a thermoplastic elastomer (TPE) is molded. The plastic substrate and TPE are joined either through insert molding or multi–shot molding. 

Insert molding is a two–step process. First, the rigid substrate is molded. It is then placed in a mold cavity on another injection molding machine and TPE is shot directly over the substrate. However, multi–shot molding takes place on an injection molding press that shoots multiple materials in a single operation. This allows the TPE to be overmolded immediately following the molding of the substrate. 

How it works?

Option 1: Prototype Injection Molds

When time and expense are not issues, the ideal method is to inject mold prototype parts using the selected substrate and TPE materials. By using the production methods and materials, the prototype possesses the same qualities as the final product.

Option 2: RTV Molds

As with insert molding, the RTV molding process uses one mold to form the base component and another for the overmolded area. Each mold requires a pattern into which the liquid silicone rubber is poured.

The Connex gives you the opportunity to evaluate more design options in less time and cost.In a single build process, and with little effort, a prototype part can be printed to simulate several variations of an overmolded product. 

The Proto3000 Advantage

At Proto3000 our skilled staff and expertise you can be determined that your product will go through all processes to reach the market fast and with absolute perfection. In just a single build, and while consuming little effort, a prototype part can be printed to simulate many forms of an overmolded product. 

The Connex printing systems lives up with a distinct technology making it one of the most important industrial innovations of the last five years. Jetting multiple materials enables overmolding in a single build process. A model can be created fast and cost effectively. This solution costs less and takes a shorter period of time. It is rapidly replacing injection molding and RTV molding to produce prototypes.

The Technology Used for Creating 3D Printed Concept Models 

Fused Deposition Modeling (FDM) Technology 

Using FDM technology allows affordability and durability by printing concept models with production-grade thermoplastics. 

FDM 3D Printers are office friendly and they produce small models in hours and large models in days. The FDM printed models can be drilled, sanded and painted according to your preference to create a perfect finishing of your prototype. 

 

     

PolyJet 3D Printing Technology

As a 3D printing process, this technology produces amazingly realistic models. The printing technology builds accurate models by incorporating multiple materials into one automated part to create prototypes that look and feel like finished products. With fine details, smooth surfaces, rigid housings, soft-touch buttons, lettering, rubberlike seals and even clear components, your models can look the part at a trade show, a presentation or even during a sales pitch.
