Calculating Injection Molded Plastic Part Shrinkage

When designing any part for injection molding, it is important to consider the shrinkage and contraction rate of the material and the associated geometry of the component. Plastic shrinkage is the dimensional change that occurs in a molded part as it cools after injection.

PRECISION MOLDING & THE INTERNET OF THINGS

While most analysis of the IoT is in respect of its positive influence on manufacturing processes, the growth in the IoT also opens up huge possibilities for micro molding as there is burgeoning demand for a variety of new and innovative micro devices.

In-house Packaging Operations Propels Growth for Tropical Trade & Industries N.V.

New blow-molding equipment and custom bottle designs boost sales by 24 percent in a year for Caribbean syrup and essence manufacturer.

Injection-Molded Plastic Allows More Creativity than Ever Before

Not being limited to metal (or a few standard plastics) opens up a much wider range of design options for engineering and design teams. They can think in more creative ways about complex geometry, performance in harsh environments, shielding considerations etc.

Extending the Life and Improving the Performance of Plastic Injection Molds

Coating mold components like ejector guide elements, cores, lifts and cavities increases the lifespan of molds while reducing maintenance and running costs.

How Colorants Affect Plastic Characteristics

Believe it or not, there is a whole scientific body of knowledge about the ways in which adding color to plastic can affect the behavioral properties of the plastic.

Injection Molding Design & Process Optimization

This approach is superior to standard molding procedures because of the high level of scientific control utilized through upfront Design of Experiments (DoE), flow analysis, process monitoring, and quality control that can quickly detect and correct any process variations.

Hand Loads: Cost Effective Solutions for Complex Plastic Parts

It's important to note that hand loads require extra labor for installation and removal. While this may skew the cost/benefit analysis, it may also be the only way to meet the customers needs.

Voodoo Automates 3D Printing to Take on Injection Molding

Michael Molitch-Hou for Engineering.com: With Project Skywalker, Voodoo Manufacturing was able to automate an important part of its manufacturing process.

Insert Molding vs Traditional Injection Molding

A typical application of insert molding is to include one or more threaded metal inserts in a plastic part when that part is intended to mate to another part in an assembly.

Smart Manufacturing in Plastic Injection Molding

Machines can now communicate failure points and collect data that can be used to improve predictive and preventative maintenance, which in the long run improves uptime.
