1. Using Thermal Diffusion Surface Transformation to Increase Die Life
October 07, 2013
After my presentation at the NADCA Die Casting Congress & Tabletop September 18, 2013 in Louisville, KY I talked to Prolong engineers about the big increase in die life possible when using Thermal Diffusion Surface Technology.
What is Die Life? Dies are made of hot work tool steel which w...

2. How to Compare Fluid and Heat Flow Simulation Software
January 06, 2013
Imagine you are working in a die casting operation and the discussion comes up to invest in fluid and heat flow simulation software and you are the lucky guy to pick the right software to buy. Fortunately there are not so many suppliers on the market and it is easy to get a first impression on the...

4. Process Parameter in High Pressure Die casting
January 23, 2012
“when the plunger moves we can’t do anything anymore”, “during fast shot we can accelerate and decelerate the plunger up to 5 times”, “when we have good castings we make a temperature image and measure the plunger speeds. If we get quality issues we just go back what we documented to make good casti...

5. Have Fun
December 05, 2011
You are a die caster coming close to the holidays, your plant is shut down and you have time to think about something else than production numbers, casting quality, break downs or process engineering. At these times when thoughts are far away of the daily challenges sometimes you find solutions in...

8. Vacuum Sucks
January 27, 2010
In high pressure die casting, porosity is created by solidifying melt, which occupies less volume than liquid and due to entrapped air, which can’t escape during cavity filling. The solution to avoiding entrapped air is to push it out of the mould. If this can’t be done, engineers try to reduce the ...

9. My Die Spits at Me
January 13, 2010
My Die Spits at Me
Everyone who has worked in high pressure die casting has experienced this habit. The plunger starts pushing melt into the cavity - then suddenly a loud bang and a dust of liquid particles rains to the ground. After some seconds the mould opens and a half empty casting appe...
