An applicator is the assembly of parts that are designed and customized to process and crimp specific electrical terminals in a production setting. Other names for an applicator are: crimp die, tool, and crimper.
A press is the machine that operates the applicators. This is a universal machine that accommodates a variety of applicators. Another name for a press is the crimping machine.
A strip/crimp unit, also referred to as a stripper unit. It will grip the wire that the operator feeds it, make a precision cut strip length on the insulation, and then moves it to the crimp area in the applicator to complete the crimp.
The difference is in the length of the press ram stroke. The standard strokes are 30mm and 40mm. Ask your representative about your press!
- 135.80 mm shut height for press
- Tri-prong clamped base plate
- T-shaped coupling to the ram on the press
It is a good idea to have at least 1 backup set on hand in the event the tools break during production. This reduces your down time and allows you to get a new set on order from Mecal by Starn. There are no fee’s for expedited orders for emergency situation. (For emergency orders please call 814-724-1057 ext. 123 or ext. 203)
- Wire Size (AWG or mm2)
- Thickness of the terminal material (in. or mm2)
- Distance between the terminals on the carrier strip (pitch)
- Type of terminal (loose piece, ferrule, multiple wire…)
- How the terminal is situated on the carrier strip (double carrier strip, end/side feed?)
Yes, Mecal engineering will take the measurements from the physical samples required with each applicator and recommend crimp specs that achieve a 17-24% compression ratio. This range with give you a tight cross section with no voids and will not damage the integrity of the components weather it be the terminal or the wire.
A ferrule is a closed barrel terminal, insulated or not insulated, designed for containing the wire strands after the wire has been stripped and crimped.
A Mylar tape terminal refers to the way the terminal is attached to the carrier strip. Instead of being a progressive stamping die, the terminals are attached with a heavy duty Mylar tape strip.
The wire stop helps gauge the wire position to ensure the proper wire brush length after the terminal has been crimped. The wire stop can also be used as an ejector pin to help take the terminated wire out of the machinery.
The adjustable terminal support ensures that when the applicators ram crimps the terminal, the terminal does not get bent down or up. This ensures the terminal quality and geometrical standards after the crimping process.
There are many factors when determining what type of applicator is best suited for a certain terminal and wire combination
- Wire Size (AWG or mm2)
- Thickness of the terminal material (in. or mm2)
- Distance between the terminals on the carrier strip (pitch)
- Type of terminal (loose piece, ferrule, multiple wire…)
- How the terminal is situated on the carrier strip (double carrier strip, end/side feed?)
The pull test value is the amount of force required for the wire to be pulled out of the terminal after it has been crimped.
This refers to how the applicators handles the excess material of the carrier strip after the terminal is removed and crimped on the wire. It will either cut it into sections or leave it as a continuous strip.
We recommend on Bench top presses the applicator to “Cut”
On automatic machines there is a hopper system that handles the scrap material, so we recommend the applicator to “Not Cut”
