» Applications

Our manufactured steel cut wire shots are superior in quality and work with precision in their various desired applications. The cut wire steel shots are used in applications for the components, such as castings, forging, fabrication, spiral springs, steel torsion springs & automotive components.

Steel cut wire shots have also found to be highly useful in various deburring applications where these have found to deliver several advantages, such as improved performance and efficiency and long service life.

The table given below shows the various applications and advantages of cut wire steel shot :

Deburring Application Reason for Deburring Advantage
Gears Functionality Increase part life, improve performance
Turbocharger Wheels Functionality Speeds production of finished part, improves performance by eliminating need to rebalance after first cycle
Anti-Lock Brake Parts Functionality Prevents products malfunction from burrs clogging small passageways
Die-Cast Parts Appearance/Safety Removes part line and sharp edges, improves appearance
Medical Parts Safety Eliminates danger to patients from sharp edges or burrs that release after implanting
Plastic Tool Housing Functionality Ensure sufficient spec and space for internal parts to fit, improves part mating
Sprockets Functionality Increase part life, improve performance
Fuel Injector Parts Functionality Prevents product malfunction from burrs clogging small passageways
Firearms Functionality/Safety/Appearance Ensure component fit, removes sharp edges, improves appearance – especially on stainless steel
Surgical Instruments Functionality/Safety Removes shine which can cause glare and impede surgeon's ability to see during procedure, smooths rough edges
Automotive Pistons Fit/Functionality Removes burrs to ensure fit of rings, improve performance during operation
Valve Plates Functionality Removes microscopic burrs that can plug small ports or injector nozzles

» Vickers Rockwell Hardness and Conversion Table


» Vickers Hardness :
Vickers Hardness is a measure of the hardness of a material or cut wire steel shot, which is calculated from the size of an impression produced under load through a pyramid-shaped diamond indenter. Developed in the 1920s by engineers at Vickers, Ltd. (UK), the diamond pyramid hardness test is used to permit the establishment of a continuous scale of comparable numbers that reflect accurately the comprehensive range of hardness found in steels.

The indenter used in the Vickers test is a square-based pyramid the opposite sides of which meet at the apex at an angle of 136°. These diamonds are pressed into the surface of the material at loads that are available in range of up to approximately 120 kilograms-force, and the size of the impression (usually no more than 0.5 mm) is calculated with the aid of a calibrated microscope.

Vickers test is reliable method for measuring the hardness of metals and is also used on ceramic materials.

» Rockwell Hardness :
The Rockwell Hardness test is a hardness measurement tool, which is based on the net increase in depth of impression as a load is implemented. The hardness numbers have no units and are generally given in the scales of R, L, M, E and K. The higher the number in each of the scales, the harder will be the material. The method was devised by Mr. Stanley P. Rockwel, who devised the test and original machines.

The technique is used to measure the hardness by pressing an indentor into the surface of steel with a specific load and then measuring how far the indentor can penetrate it. While there are several Rockwell tests, the most widely used is Rockwell B. Rockwell C, which are used on hard materials.

In the case the material is highly thin, lighter loads must be used. Resulting in Rockwell scales, like - 30T, 1ST, Rockwell 15-N and 30-N. There are conversion charts that provide for conversion from one method of hardness to another, but it is important to note that these conversion charts cannot exactly convert from one to another.
