Optimized Feeding Systems

It is well known that metals change volume during solidification. This volume change must be compensated during solidification otherwise shrinkage defects can occur in a casting, making it unusable for its stated purpose.

This has been solved through the use of adding a metal reservoir commonly known as a "feeder" the purpose of which is to supply liquid metal to the casting as it cools and solidifies.

As this technology has developed and been improved, newer types of feeder materials have become available, including combinations of exothermic-insulating and highly exothermic compositions. The choice of material depends upon the application.

An Interesting Approach to the Product Installation Process

I always have believed that to successfully implement a new resin system in an existing or new customer, it is necessary to take into consideration four important factors: Materials, Methods, Manpower, and EH&S. The first three represent a three-sided equilateral triangle, which in turn is being supported by safe practices and products. If any of the sides of the triangle are unbalanced, the chances of carrying out a successful implementation could be compromised. Any substantial deficiency of any of the 3 M's (Materials, Methods, Manpower), will require that the other two be challenged at a higher degree.

EcoLite

EcoLite refractory coatings feature the latest light-off / fast drying technology. By using VOC-Exempt solvent packages, the flexibility and advantages of solvent based coatings can now be realized while minimizing the permitting of VOCs. Whether lowering the VOC impact of alcohol coatings or increasing productivity of water based coating applications, EcoLite coatings provide a unique value to today's foundry.

Environmental stewardship: NOT JUST A TREND

The metalcasting industry has a great reputation when it comes to recycling. However, environmental stewardship involves more than recycling. Using materials with more advanced environmental benefits is where metalcasters can take a leading role to mitigate some of the environmental challenges they face while creating a healthier and safer work environment.

Understanding 3D Sand Printers and Binder Technologies

AM for cores and molds is gaining popularity because of the flexibility and complexity it offers in production, but productivity is critical to the long-term prospects

Additive manufacturing of sand cores and molds has attracted the attention of many foundries in recent years due to the process' unique ability to form core shapes that cannot be manufactured using conventional coremaking techniques. It does this by a process called "binder jetting": a reactive resin, most commonly, a furfuryl alcohol-based (FA) binder formulated for the application is deposited on a substrate. Typically, the substrate is a silica sand that has been pretreated with an acid catalyst, but it can be a number of other aggregates used in metalcasting, such as zircon and synthetic ceramics.

Wedron Flux Processing System - Announcements

New drossing, clearing and degassing fluxes for copper based alloys. Eco grades reduce porosity by removing dissolved gasses in your copper based alloys. Simple plunge applications are very effective in reducing your scrap rate.

Our new Zinc flux can be used on emersion tube melting and holding furnaces without corrosion concerns.

HA International has the only non-reactive commercial grade LEAD flux. Reduce the metallic content of your dross. Weight reduction saves not just alloy, it's an ergonomic savings. A reduction of up to 40% in weight will reduce operator injuries.

Our Rotaflux and Injection systems have been upgraded and now have the ability to harvest data. Now you can find out what happened on third shift two weeks ago. Our systems record all functions or each cleaning and degassing cycle:
1. Retained Data Options
2. Operator Identification
3. Ladle or Furnace Identification
4. Time and Date
5. Gas Flow Rates
6. Flux Addition
7. Rotor Speed
8. Rotor Amp Draw Indicates Performance
9. Cycle Times, Injection & Purge

Evolution of Foundry Shell Sand for Today's Foundry

Simple Solutions That Work - (Issue 9, September 2018)

The Shell Sand process or "Croning" process was invented by Dr. Johannes Croning in Hamburg, Germany in 1944. This process is the oldest core and mold making technology that utilizes synthetic resins. Although many additional sand core and molding making technologies have since been introduced, the Shell Sand process is still a very effective core and molding process today.

Enviroset 3D Jet Resin, is a low viscosity thermosetting furan resin that has been specially manufactured for use in all 3D Printers for sand cores and molds and is suitable for use with all types of metal. This furan resin offers a number of features and benefits that set it apart from conventional furan resins on the market — contains no nitrogen, low water, non-reportable formaldehyde and phenol, low viscosity and high tensile strength

Doug Trinowski Presents Hoyt Memorial Lecture

April 2017

MILWAUKEE, Wisconsin - (April 2017) - The American Foundry Society’s Hoyt Memorial Lecture was established in 1938 and has been a highlight of every AFS Metal Casting Congress since then. The chosen lecturer is selected for his/her contributions to the metal casting industry and this year HA International’s Douglas Trinowski was given the honor of presenting the lecture. His presentation was on “The Power and Need for Research in Metalcasting”. Doug gave an engaging presentation on past metalcasting research that has led to measurable improvements in the industry and focused on the need for continued research as supported by AFS. He also outlined many examples of critical needs and challenges in the industry that can only be resolved with organized research. Finally, Doug focused some time on how research is conducted in various countries and the need for improving the technical transfer process.

Doug is the former Vice President of Research and Development for HA International and the current Director of Special Projects. We are a successful organization today due in large part to the leadership of Doug and the contributions of him and his team over many years.
