Such variable result from the Application of material, men, machine and manufacture-ring conditions only when these variables are regulated to the extent that they do not detract unit is main shop of sonalika international tractor ltd .In necessarily from the excellent of the ring-ring process as reflected in the quality of the finished product, can the control of quality be said to exist. Generally, inspection, which is the process of sorting good from bad, is the process of sorting good from bad, is considered as a form of quality control. But quality control and inspect-ion are different. Conceptually, a Q.C. aim of prevention of defects at the very source relies on effective held back system and corrective action procedure. Acceptance of material after subjecting them to in section at inward goods store is inspection concept. Q.C.concept is to take early step to ensure that the material to be supplied is going to be manufactured to the plant's requirements. So as to ultimately eliminate the in ward goods inspection. Discovering that the components produced are not as per required dimensional specifications due to wrong tool or improper settling after the production is over is inspection concept. To prevent the issue of a wrong tool and to have a set up approval procedure prior to starting continuous production and keeping a simple check during production, are Q.C. concepts.

Q.C.uses inspection as a valuable tool. In quality control programmed inspection data are effectively used to take prompt corrective actions to arrest the incidence of defects in the job on hand to plan the prevention of occurrence of the same or similar defects in future.

OBJECTIVE OF Q.C.

The main objective of a quality control programmed in sonalika international LTD.

(1) Evaluation of quality standards of incoming material, product in actual manufacture, and have out going product.

(2) Judging the complicity of the process to the established standard and taking suitable action when deviations are noted.

(3) Evaluation of optimum quality obtainable under given conditions.

(4) To improve quality and productivity by process control and experimentation.

(5) Developing procedures for good vender vendee relations.

(6) Developing quality consciousness both within and outside the organization.

QUALITY CHARACTERISTICSFollowing are main quality characteristics for components used in sonalika international tractor ltd.

(1) A dimension is a characteristic.

(2) A chemical properties is a characteristic.

INTRODUCTION:-

The paint shop is the one of the most modernized shop of International Tractors Ltd. The out looking and surface finish is of world class quality. Paint give protection to tractor from corrosion for enhancing the appearance for a longer period and at the same time it protects the body from rust. The paint consits of Linseed oil , Pigment (as per requirement of master piece) and turpentine oil or some other solvent to thin the mixture. Magnesium silicate is also added to impart improved resistance to cracking of the paint film. The drying time hardness and elasticity of paint film depend principaly on the drying oil, temperature of oven, and the time for which it is kept in the oven. The present paint shop is giving an excellent coating , production and finishing of componentsof tractors parts.

\

PROCEDURE FOR PAINT QUALITY:-

(1)Even covering of paint should be there on the components. The surface should be smooth and there should be no unevenness.

(2)The minimum required thickness of painted surface should be

65 microns.

(3)The minimum gloss level required is 95%.

(4)The components should be free from dust particles.

(5)Minimum allowable dust is 5%of the total painted area.

(6)The components should be free from dents and other superfical marks.

(7)Minimum allowable dents are 1% and these should not be on the face surface

(8)The painted surface must pass cross batch test 100/100.

(9)The shade should be matching with the master shade (this test will bbe performed at the time of receiving of paints ,however in doubt the master panel should be consulted.)
