Seven Key Advantages of Hot Runner Systems (April, 2002)

While both hot runner and cold runner systems have their benefits, for design flexibility as well as reduced cycle times and costs, hot runner systems will probably be the better choice. This image shows a two-cavity, valve-gated hot runner bolt-on system. Image courtesy of Caco Pacific Corp.

The Realities of Aluminum Tooling (December, 2008)

Here, a standard cooling bushing is used to isolate the nozzle tip from the aluminum tool. Many variations of this assembly are offered. Image courtesy of Clinton Aluminum and Stainless Steel.

Mold Cleaning Done Right Takes a Systematic Approach (October, 2013)

Parting-line PM does not necessarily occur with the mold in the press. It also involves more than a simple wipe-down. As part of the MGS PM tool shop’s best practices, some molds require partial disassembly for an appropriate P/L PM, including removal of any slides and other moving components.

How to Deal with Graphite Dust, Part 1 (June, 2012)

The best system for shops heavily engaged in graphite machining is a fixed unit with sufficient vacuum to draw the dust from the machine, through the duct work and into a collection bin. Image courtesy of Poco Graphite. Image courtesy of Poco Graphite.

Choosing the Right Tool Coating for Your Machining Application (November, 2005)

Selecting the correct coating and its attributes can mean the difference between a successful operation and one that shows little to no difference. These are TiAlN-coated end mills. Photos courtesy of OSG Tap & Die.

Texturing Molds for Thermoplastics: Factors for Success (December, 2010)

Some transfer patterns require hand-blending, particularly in the corners and edges where the pattern might not otherwise meet perfectly. If you picture trying to wrap a flat sheet with this pattern around these contours, you can imagine some of the skills required to blend everything together. Image courtesy of Wisconsin Engraving.

Why Choose a Valve-Gated Hot Runner? (February, 2001)

This figure shows a valve gate assembly. Moldmakers need to be aware of how different gating technology can affect their customers when designing a hot runner system into a mold. Image courtesy of Husky Injection Molding Systems.
