Latch Trajectory

Outer Pannel:

Outer pannel is the one that we see from the top as the design of the car. This gives the stylish look so there should not be any of the welding seen out side. it holds the inner pannel.

Inner Pannel:

Inner pannel has all the design considerstions. in the inner pannel we use the emboss option to project the sheet and trim option to make a cut on the sheet.

The Mastic data points are the circular points with glue of 5mm and it can give strength to 80mm radius sourrounded to it. so it is important to provide the mastic point for each 80mm dia.

The Hinge assembly is provided with the touch constrain and parallel to the datum plane. the emboss to fix the hinge assembly is being provided on the inner pannel.

The stricker is being provided with the embossed face with the latch tragectory.

Hemming:

The hemming operation is done in order to hold the outer and the inner pannel. to Provide hemming operation the sharp corners are cut out and also the extra 2.65mm of sheet is bent to provid the hemming operation.
