3D Printing - Manufacturing-Tooling Solution - Injection Molding 

Injection Molding is a fast manufacturing procedures, which involves feeding small plastic beads into a heated screw and barrel system that melts the plastic into a high–viscosity liquid. The screw then forces the molten plastic into a closed mold that provides the shape, cooling and solidification, and finally ejects the part.

Injection Molding is an economical and quick manufacturing procedure; however, prototyping involves a costly tooling system, since every part requires its own injection tool. The procedure requires mass production for a positive ROI. The minimum amount of parts produced is 10,000. Building an injection molding tool may take weeks or months to be created. Multiple iterations may go from the producer to the tool builder until the final part design and quality are achieved, increasing costs and product time to market.

How it works 

Production–material prototypes, crucial for the design process, are difficult to justify financially, because they require the same costly tooling as the finished product. Further, they are most useful when produced quickly, but tooling takes time.

Several traditional rapid–prototyping technologies can produce precise, complex parts, but these techniques use special plastics, usually very different from production materials. Another conventional prototyping method substitutes lower–cost, simplified and smaller tools (e.g. one cavity instead of multi–cavity) or tools made from softer, cheaper aluminum. Some cost is saved, but the tools are still expensive and time–intensive to produce.

A different approach is to produce the tool with 3D printing (also called additive manufacturing). The printed injection molding tool (PIMT) can be installed on the injection molding machine to mold the part using the actual production material. PIMTs can be built cheaply and fast, ready to inject in a few hours. If design changes are needed, the corrected PIMT may be ready and installed in the injection machine the same day. PIMTs are not production tools; however they provide a clear advantage, being both cheaper and faster when a limited quantity of parts is needed, such as for commercial prototyping.

The Proto3000 Advantage 

Create your injection molding prototypes with the Proto3000 Services Team to save time and money for your business. We offer rapid prototyping and 3D printing services in our manufacturing facilities by using Polyjet technlogy to create highly precise prototypes and parts. Polyjet tooling is the best fit for injection molding to create products of low quantities, design changes are likely to take place during the prototyping phase and complex geometries or parting lines are present. 

Contact the Proto3000 Services Team for further information on how we can help you with this solution. If you want to speak to a LIVE PERSON - CALL 1-888-88-PROTO (77686). 


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.
