The sides of the crimp tooling are angled i. The other specifications do not state requirements on tooling.

It was written by the Volkswagen Company primarily for their suppliers. The VW and A specifications states that for crimp height vw 60330, a micrometer with a point and a blade Fig. For more information on the respective specifications, please vw 60330 to:. Finally, the new systems are far less expensive. The VW specification mandates their use depending on wire size.

vvw It is vw 60330 as a tooling reference, not as a quality measurement parameter. To comply with USCAR you could not use the standard lb N pull test devices unless it had an accuracy vw 60330 better than 0. What are companies measuring and is it really correct? In these difficult times, wire harness manufacturers are looking to expand business in their existing markets and are looking for new markets. When you have some manufacturing companies who want products made to the UL spec and others who 660330 products made to SAE specs, how do you keep track of the differences?

Much of the discussion to come will reference the automotive specifications. The wire used is 600330 26 AWG vw 60330 the crimp height and width is as specified by the manufacturer.

Crimp Quality Standards Comparison and Trends

Finally, base thickness 10 is an indication if the material has been over-crimped. The VW specification provides higher pull test vw 60330 if the insulation crimp is left intact. The reason is vw 60330 eliminate the possibility for the flash to affect the measurement Fig. Pull rate is the rate at which the wire and the terminal are pulled apart.

Micrograph systems, or crimp cross sectioning equipment, were typically only seen where applicator tooling was manufactured or in the labs vw 60330 the large wire harness suppliers.

The support angle 4 and support height 5 are indications of how vw 60330 the terminal is in the crimp and how strong the crimp will be over time. Only the VW specification states that 5 samples must be tested for each set-up. The others do not address it.

Much of the above discussion might not apply directly to your company right now. As you will see in the chart below, tolerances are the same but the corresponding wire sizes differ. Therefore, getting a comprehensive vw 60330 on the entire crimp is faster, easier and vw 60330 expensive. The measurable crimp width 3 is simply taken at the widest point of the terminal. Some companies will use their own tolerances but some employees will apply them differently.

If the terminal is too vw 60330, the face ends may touch or be too close to the bottom of the crimp. The solutions in the new systems have a Ph value equal to that of water so they are much safer to use and no special procurement and vw 60330 processes are required.

The face end clearance 6 is an indication if the terminal is properly sized to the wire. Aside from simple mistakes made during the harness manufacturing 603330, vw 60330 can go out of tolerance in the manufacturing process and frequently companies v to use terminals that are too large for the wire. Burr vw 60330 8 and burr width 9 are indications of crimp anvil wear. It is optional only when pull testing is done.

Both standards were created by the Society for Automotive Engineers. Crimp vw 60330 is a bit of a challenge. Quality standards are getting tougher each year.

The UL and VW specifications do not specify a rate, so manufacturers can use the fastest method available as long as there is no sudden vw 60330 on the sample. The table below indicates the frequency requirements as stated in the VW specification. This can be challenging because as we all know, tooling wears. USCAR recognizes that not all wires are the same.


The distance between face ends 7 is also an indication vw 60330 how centered the terminal is in vw 60330 crimp. Keeping all of the specifications straight and understanding all of the differences is increasingly difficult. USCAR specifies a rate between 50 — mm per minute, but mm vw 60330 minute is preferred. Larger companies with multiple plants, possibly in multiple countries are most susceptible to these kinds of challenges.

More issues are seen in smaller wire sizes, so testing frequency is higher. New systems on the market are much more suited for use in the production 60330 because the crimp analysis process is much faster since there are fewer steps. There are so many vw 60330 to adhere to and each manufacturer vw 60330 have different requirements. It can be important because different values may be achieved if vw 60330 rates are not consistent. So who is correct? Only the A specification makes crimp height measurement optional.

The crimp width tolerance is usually vvw listed in terminal specifications because it usually refers to the tangent width, which is the non-measurable crimp width. Vw 60330 standards are getting more rigid each year. The more vertical the angle is 6033 the larger gw height is the vw 60330 the crimp will be over time. Technically it is between the tangents of the radii of the crimp die. They were large table units involving epoxies and acidic etching solutions.

Vw 60330 preceding discussion covered a very small percentage of the respective specifications, but hopefully this has given you a better understanding of the different specifications and how they may be applied in your business. These issues make data collection more difficult and vw 60330 we all know, data collection can be a very time-consuming and inefficient process if not done correctly.
