Base on the lean concept of waste reduction, cost reduction and continuous improvement, evaluation
and measurement indicators are total throughput, cycle time and difference of percent utilization

Introduction
Nowadays, weight reduction of automotive parts is an issue of prime concern.
Thus, this material offers an efficient alternative for the weight reduction of numerous manufactured components such as pinion gears or camshafts.

Fig. 2 shows Arrhenius plots of fitted jump frequencies for the five samples in each series, with data for In3(La1-xPrx) and (In1-xSnx)3La on left and right, respectively.
For each system, values of a were adjusted to give the best overall simulation of data shown in Fig. 2.
Thus, there is a large reduction in jump frequency when Sn starts to substitute for In in In3La, but essentially no change when In substitutes for Sn in Sn3La.
Since Sn3La has only a slightly larger lattice parameter than In3La, 0.477 vs. 0.473 nm, the strong reduction in jump rates does not appear to be caused by an oversized Sn impurity.

Experimental data was obtained using FESEM (Field Emission Scanning Electron Microscopy), EDX (Energy Dispersive X-Ray Spectroscopy), ATR-FTIR (Attenuated Total Reflectance – Fourier Transform Infrared Spectroscopy) and TGA (Thermogravimetric Analysis).

Field emission scanning electron microscopy (FESEM) and energy dispersive X-ray (EDX) Analysis The data were obtained using an ultra–high–resolution Field Emission Scanning Electron Microscopy (FESEM), NOVA 200 Nano SEM, FEI Company.
By comparing the 6h and 15h spectra, it is possible to conclude that a remarkable DMMP band reduction was achieved, overall – the 1454, 1238 and 1184 cm-1 bands have almost disappeared, while the intensity of the rest of the bands has been greatly reduced.
The results showed a significant reduction in DMMP related peaks’ intensity – even the total disappearance of some – which indicates that DMMP was being successfully degraded.

The use of variant No. 9 was provided a reduction of permeability coefficient to 0.04-0.05 for the thread-adhesive joint (before aqua-washing).
According to the data obtained previously, an increase in the amount of acrylic acid nitrile in the copolymer contributes to an increase in hardness.
Analysis of obtained data showed that gluing of thread compounds of articles reduces permeability of fluff packages elements.
It is noted that the use of the ASFM for gluing of thread sutures provides a reduction of Cper by 6-8 times compared to the existing technology of products preparation, which does not imply prevention of permeability to fluff.

On the second day, there tends to be an increase in mass in the sample that has a low compacting pressure, but there is a reduction in mass at a relatively high compacting pressure.
A very significant mass reduction occurs in samples that have the lowest compacting pressure, this is because the sample has a low bond between particles.
Fig.4a is the SEM data from the highest degradation rate samples (250 MPa compaction pressure and 350℃ sintering temperature) and Fig. 4b is the SEM data from the lowest degradation rate samples (350 MPa compaction pressure and 400℃ sintering temperature).

Introduction
Weight reduction can improve the performance of automobiles and can directly reduce energy consumption, which is beneficial to fuel economy improvement and environmental friendliness[1].
Symbols are experimentally measured data; dashed lines were obtained by the second-order polynomial fitting algorithm.
The flow stress-strain relationships of AA6082 under HFQ® conditions were obtained from tensile test data and the representative curves are shown in Fig. 7.
The viscoplastic response of the material results in increasing strain rate, in the range 0.1-4/s, leading to an appreciable increase of the flow stress level and strain hardening; increasing temperature, in the range 350-535°C, leading to a significant reduction in the flow stress level and strain hardening.
