Advantages of 3D Printed Parts in the Injection Molding Process

The remarkable breakthroughs offered by 3D printing have made a major impact on the injection molding process and industry. Also called "additive manufacturing", 3D printing produces parts through a material layering process.

Often used to prototype a product, this process can act as a final design proving - as well as a means to assess the final design. This means providing a simple method for verifying the testing, fit and functionality of parts before being injection molded.

Injection Molding Advances Use of 3D Printed Parts

The biggest advantage continues to be the ease this process allows for the physical testing of a design, which results in reducing your product’s time to market. Parts that have thin walls and complex geometries - parts that are durable or even those providing a bridge-part function can all be 3D printed.

Mass production using 3D printing does include its challenges. Even though this additive manufacturing process can quickly produce sample parts at very low cost - the selection of printed plastics remains limited as well as the difference in surface finish and each part would have to be finished individually increasing labor costs.

Moving Your 3D Printed Parts into Major Production

When designers create a part for additive manufacturing with the intent to produce the product through the injection molding process a few things should be considered. First, design draft into the part, so when it comes time for injection molding you won’t have to return to the CAD file and modify the design.

Also apply other modifications to include features specifically needed to reduce stress concentrations that apply both to 3D printing and injection molding. Some of these features include sharp corners and radii and ensure smooth changes from thin walls to thicker walls this will reduce the potential of warping for the injection molded part.

These changes are needed for smooth transitions and will prevent shifting to injection molding from becoming overwhelming.

Understand the Causes of Shrink & Warp in Plastic Injection Molding

In order to understand the causes of shrink and warp in custom plastic injection molding, it is essential to comprehend what shrinkage is. Shrinkage is a reduction in size of the molded part as it cools. All injection molded parts shrink, but they do this by different degrees.

Considerations for Sourcing Injection Mold Tooling for Plastic Components

When it comes to injection mold building, strong engineering capabilities, technologies and journeymen tool makers provides options and solutions to customers to help mitigate the most difficult aspects of part and mold design.    

It is critically important to work closely with your injection mold builder from the beginning of your project to maintain risk while helping keep the mold build on its timeline as well as on budget.

A quality injection mold that optimizes cycle times, reduces mold downtime will quickly pay for itself during production runs.

Technologies, Equipment and Personnel Achieve High Quality Molds

Tooling engineers utilize technologies to develop 2D and 3D computer generated files of injection molds and mold fill simulation software to create mold designs with proper actions, runners, gates, venting and cooling to achieve reliable and consistent plastic components.  From these 2D and 3D injection mold models detailed tool paths are created for specialized CNC machining. 

CNC high speed machining centers and EDM’s are using this software and other advanced technologies to help journeyman tool makers manufacture injection molds with enhanced accuracy, efficiency and precision. This provides an almost unlimited geometry which has become good news for the production of complex plastic components.

An injection mold building tool maker’s job  requires advanced training to calculate the feeds and speeds required to make precise cuts with drills, end mills and other sophisticated CNC cutting tools - a job that requires a 4 to 5 year apprenticeship program, and significant on the job training.
