In-die joining transforms press into assembly system, Part II

February 24, 2009

By: ,

In-die joining systems help stamping shops to expand their operations to include sub-assemblies and full assemblies without additional downstream equipment and processes, so they can carve out a bigger share of the production work.

Stamper rebuffs recession with retool

February 24, 2009

Richland Manufacturing, a subsidiary of Eagle Wings, a tiered automotive supplier, retooled with a new stamping press cell equipped with an electromagnetic die handling system. The retool effort also included installation of a 330-ton tie-rod type press, and a compact coil feeder.

Coil Shape problem

Controlling flat-rolled shape

February 10, 2009

By: ,

What processes do you need to make sure your coil is flat? What is flat enough? You need to determine where you are at the start, where you want to end up, and how to get there. Once you have determined which shape problem you have you can determine which type of equipment is effective in controlling it.

Converting your fluid systems to green

December 15, 2008

By:

Metal forming, stamping, and washing fluids traditionally have been thought of as "necessary nuisances" to be used once and thrown away. That mindset is changing.Incorporating "green" or environmentally friendly fluids and fluid management systems can extend fluid life and minimize waste, providing valuable cost savings.

3-D Design Software

3-D die design for a 3-D world

November 11, 2008

By:

3-D die design software allows you to build the die on the computer screen, fully assembled and ready to run as if it were built and sitting out on the shop floor. SolidWorks-based Logopress3 software even allows you to then simulate the die running in the press. Even better, it detects crashing and strip feeding interference problems on your computer screen rather than after the die has been built.

Hydraulic Press Hot Stamping

Hydraulic presses for hot stamping meet weight, safety mandates

October 28, 2008

By:

Hot stamping of automotive structural safety components developed in response to mandates levied by the U.S. National Highway Traffic Safety Administration (NHTSA) 1 to improve vehicle crash integrity while also reducing vehicle weight to help meet fuel efficiency standards. Heating a high-strength steel (HSS) component of a boron-steel alloy to the austenitic range—a super-heated solid solution state, ~ 1,700 degrees F (950 degrees C)—improved drawability, and then quickly cooling the part in a water-cooled die, or quenching, transformed the crystalline structure, increasing the formed component's strength-to-weight ratio.

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.

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.
