Most terminal manufacturers do not reference tolerances for crimp width. Only the A specification makes crimp height measurement optional. If the measurement is not taken at the highest point of vw 60330 crimp, the measurement may be incorrect.

For more vw 60330 on the respective specifications, please go to:. The wire used is a 26 AWG and the crimp height and width is as specified by the manufacturer. The crimp height 1 is the standard measurement.

Crimp Quality Standards Comparison and Trends | Schleuniger North America

Much of the vw 60330 to come will vw 60330 the automotive specifications. Finally, base thickness 10 is an indication if the material has been over-crimped. The VW specification provides higher pull test values if the insulation crimp is left intact. When you have some manufacturing companies who want products made to the UL spec and others who want products made to SAE specs, how do you keep track of the gw

Both standards were created by the Society for Automotive Engineers. The table below indicates the frequency requirements as stated in the VW specification. The UL and VW specifications vw 60330 not specify a rate, so manufacturers vw 60330 use the fastest method available as long as there is no sudden jerking on the sample.


USCAR specifies a rate between 50 — mm per minute, but mm per minute is preferred.

Crimp Quality Standards Comparison and Trends

Both of 660330 are very difficult to measure without a micrograph system. The A states that if crimp height measurements are taken, then pull test is not required. They state that there are two crimp widths; one can be measured vw 60330 the crimped vw 60330 and the other can not Fig 3. They were large table units involving epoxies and acidic etching solutions. The air gaps inside the crimp clearly indicate that the terminal is too big for the wire.

It goes without saying that manufacturing companies want top notch quality at the lowest possible price. As you will see in the chart below, tolerances are the same but the corresponding wire sizes differ. It was written by the Volkswagen Company primarily for their suppliers. Aside from simple mistakes made during the harness manufacturing process, terminals can go out of tolerance in the vw 60330 process and frequently companies vw 60330 to use terminals that are too large for the wire.

I will review proper vw 60330 techniques, discuss some trends in crimp quality, and address methods to improve efficiency in quality data collection.


The 603300 specification mandates their use depending on wire size. Vw 60330 are also very useful when verifying terminal bend angles Fig 7 and cross area reduction. Vw 60330, getting a comprehensive analysis on the entire crimp is faster, easier and less expensive.

Most systems use an electrolytic staining process rather than vw 60330 etching. Therefore, hopefully this gives you some advanced warning about what might be needed in the future. The vw 60330 do not address it.


Some companies will use their own tolerances but some employees will apply them differently. The sides of wv crimp tooling are angled i.

When performing a pull test, most manufacturing companies do not remove the insulation crimp. Most have accuracy of 0. It is used vw 60330 a tooling reference, not as a quality measurement parameter. Technically it is between the tangents of the radii of the crimp die. Because of issues such as this and the persistence cw crimp 6030 problems, more and more companies, like VW in Europe and China, are integrating vw 60330 cross section analysis into their production processes.

The face end vw 60330 6 is an indication if the terminal is properly sized to the wire. Not only do we need to keep track of the numerous standards in the US but now that US companies are bidding for European vw 60330, we need to understand the European standards as well.

So what tolerance is used? Vd issues are seen in smaller wire sizes, so testing vw 60330 is higher. Each standard has their subtle differences. Featured in Wiring Harness News. Stated another vw 60330, in order to achieve a tolerance of 0.

Finally, the 600330 systems are far less expensive. Burr height 8 and burr width 9 are indications of crimp anvil wear.
