NADCA, "Take a Detailed Dive into the Various Methods of Diecasting Process Control"

Posted by Dr. Morris Murphy on Apr 17, 2019 12:10:10 PM

It is important to know what type of control method is applicable to each of the die casting machine/die/process systems.

North American Diecasting Association (NADCA) has created a three level approach to addressing process control. This series is broken down by beginner, intermediate and advanced courses suitable for people with varying levels of knowledge in this area. Learn more at this NADCA page.

Part 1: Basic Approach to Process Control -
This covers the traditional methods of controlling the process and what feedback you use to control it. It then expands on this and shows the usefulness of some simple math terms. It allows the company to see how stable their company is in from day-to-day. It then looks at the causes of variation from that stability and how to solve the three most common causes.

Part 2: Intermediate Approach to Process Control 1 -
This expands on the Basic Approach by using the basic math terms to gain a Process Capability Analysis for the plant, it uses this to explain how to get process control. It covers how you know if your process is out of control. Finally, it goes over the various methods of controlling the process (set and forget, continuous display and Statistical Process Control).

Part 3: Intermediate Approach to Process Control 2 -
After Intermediate 1, this follows on to explain the various Bell curves and what they mean, it explains that the tolerances of the product are from the customer but the tolerances on the PROCESS are your decision. It covers how you define “A good process” and how to make the measurements real. It gives examples of using SPC on various shot parameters, it then covers short term and long term drifts.
Date: April 25, 2019

Part 4: Advanced Approach to Process Control 1 -
In this, we define what variables we have control of and what impact this has on the many variables that we can’t directly control. This then covers the measurements that should be taken and the great care in choosing the right variables to measure. This data is then used in two ways,
* Historical- what was measured in the past and how can the company gain the best information.
* Planned Trials- what is available to let the company carry out a multi variable experiment and gain the best advantage for future production.

Part 5: Advanced Approach to Process Control 2 -
This final webinar brings it all together. It covers planning a trial for both parameters that are changed and variables that are measured. It goes through a DoE approach to show the power of the method. Examples are given of real trials that enabled a very defined set process parameters to be reached. This impacted strongly on achieving an operating window that enabled a stable, low reject production of difficult parts. Using examples from real life trials should assist the die caster to apply these methods in their own plant.
