Biobased vegetable oil lubricant

Green lubes under a microscope

October 14, 2008

By:

Stamping parts with vegetable oil is becoming more a reality every day. For a metal working lubricant—whether it be soluble, semi-synthetic, or synthetic—to be USDA-classified as biobased, it must contain, at minimum, 40 percent to 57 percent of renewable resources. Just because a product is biobased, made from a varying percentage of renewable resources, it does not necessarily make it readily or ultimately biodegradable. Green lubricants offer enhanced lubricity and a high viscosity index. These oils are less toxic to the environment and are easier to dispose.

Carbides in applications

Carbide in tool and die

September 30, 2008

By:

Carbide is a two-phase, powder-metallurgical (PM) material consisting of a hard material phase and a binder metal phase. The hard material provides the necessary wear resistance, and the binder metal guarantees appropriate toughness. To select the appropriate grade for a tool and die application, it is important to have a detailed knowledge of carbide and how its properties can be influenced.

Next-generation large-tonnage presses rely on new software for virtual integration

September 15, 2008

By: ,

Operating large flexible press systems without sacrificing speed and quality can be a complex undertaking. New software takes CATIA to the next level. Users can really learn how to "drive" their large presses optimally by virtually integrating the slide motion, the transfer movement in a way that allows 1) the press to be built, 2) the transfer to be integrated and 3) the die to be built to most efficiently run in the system--a quantum leap. Now being used by Ford and Magnum.

3 deadly tool design sins

August 12, 2008

By:

Among the many factors to consider when designing and building a stamping die are the material to be processed, the press that will run the die, and specified part tolerances. Inadequate knowledge of these factors can contribute to die failure and production and quality problems.

How to run presses faster without increasing scrap

July 29, 2008

By:

The catch to operating at higher production speeds is that metalformers often see jumps in scrap rates and accelerated wear-and-tear on the press and tooling. New, and some tried-and-true, mechanical press technologies help metalformers strike a balance between high speed and high precision.

Reading progressive die strip — Part II

June 2, 2008

By:

Editor's Note: This is the second part of a two-part article about reading progressive-die strips. Part I, which appeared in the May issue, covered the causes of pilot hole distortion and mismatched cuts. Hard marks, otherwise known as coin marks, occur when metal is severely squeezed between two...

Driven to integrate

May 13, 2008

By:

Changes come often in the steel industry--a business that sticks around long enough might eventually bear little resemblance to the version established at its inception. This is the case for Parkview Metal Products, Lake Zurich, Ill. The company opened in 1950 as a tool and die shop in Chicago, later moving and shifting its focus to automotive, electronic, and grill components. The company believes its culture is changing for the better and plans to continue developing its 5S initiatives, increasing its on-time delivery, and reducing its scrap rate.
