Here’s a view from the trenches of a tooling manager who, over 30 years, has experienced the joys and pains of using virtually every type of hot runner on the market. Part 2.

Get a better understanding of their use, proper sizing, and how the tool design and setup in the machine can impact failures in manufacturing.

With cavity steel or alloy selection there are many variables that can dictate the best option.

Here are more tips on using hydraulically actuated devices on your tools.

Addressing hot-runner benefits, improvements, and everyday issues from the perspective of decades of experience with probably every brand on the market. Part 1 of 2.

Your problem may be related to tooling, material, processing, or combinations thereof. Here’s how to find the root cause.

Gate size and shape—unlike gate location—don’t often get the attention they deserve. Many common assumptions about gate geometry deserve to be challenged

Beyond just the “invoice price” of a barrel, processors should consider factors like the composition of the inlay, quality of the backing material, straightness, concentricity, machining imperfections and packaging/handling, to understand the true cost of owning a barrel.
