Over 50 years ago, Weiss-Aug began as a precision metal stamping company focused on supplying tight-toleranced miniature high-speed stampings for the most intricate and complex projects. Today, we offer numerous industry-leading capabilities, as well as our own newly developed technologies, to deliver the superior quality our modern clients need to strengthen their competitive edge.
Precision Electrochemical Machining
Precision Electro-Chemical Machining (ECM) is the process of machining workpieces through the anodic dissolution of metal. Many metals can be electrochemically machined, including high-alloyed nickel, stainless steel, titanium, and other hardened materials.
There is no contact with the workpiece and no heat input, so many of the disadvantages experienced with traditional machining methods, e.g. tool wear, mechanical stresses, micro-fissures caused by heat transfer can be avoided with this unique process.
The Weiss-Aug Group provides P-ECM for products and parts where the geometry would require too many steps to achieve, or not possible with stamping, laser cutting, or other manufacturing technologies.
Plasma Electrolytic Oxidation
Looking for a lightweight corrosion-resistant alternative material? Plasma Electrolytic Oxidation (PEO) of Aluminum can achieve hard crystalline oxides and offer superior strength and lower expense.
Physical Vapor Deposition
Magnetron Sputtering is a unique Physical Vapor Deposition (PVD) technology where thin layers of metals and dielectrics are deposited onto a substrate. When electroplating is not accurate enough, PVD is often a great alternative.
Shear Edge Stamping Technology
When your part requires cleanly sheared straight edges with little or no diebreak, excellent flatness and no need for machining, fine blanking had been nearly the only solution until now.
Our proprietary “Shear Edge Technology” process achieves part quality equal to or, in many cases, better than traditional fine blanking with the economies and flexibility of the progressive stamping process.
We can often eliminate the “die roll” condition present in fine blanking and conventional stamping by employing specially designed stations in the progression of the strip advance. The die roll condition is a curved contour on the edge of the side of the blanked part and is developed by the action of pulling the material before the punch travels through the material.
This process eliminates most of the fine blanking disadvantages, such as burrs, and results in a quality-consistent, very cost-effective process.
Shear Edge Technology can be utilized with various applications including mechanical automotive, powertrain, and transmission components.
About Lupine Research
Founders John Francis, Ph.D. and Alex Macpherson, Ph.D. initially started the company in 2012 to develop new materials and manufacturing techniques for the medical device community.
Subsequently, Lupine Research has partnered with the Weiss-Aug Group to grow their manufacturing expertise and reach. As part of this group, we bring fabrication and automation solutions to market, in turnkey fashion.
We have invested in state-of-the-art facilities in order to better engage the American engineering development and manufacturing community.
