manufacturing technique in which heated molten polymer is forced into mold opening under huge pressure. The heated plastic in the mold then cools down, solidifies to form desired shaped part. Top cover bearing is a part used to accommodate in automobile suspension systems. Material selected is Nylon 6 with 30% glass filled (black). The grade of the material is SGR 30 and the shrinkage factor of 0.6%. The component and tool designs are done with the help of Unigraphics (NX 11.0). Mold flow analysis is carried out using the software Easy flow advance NX 11.0. Finally, manufacturing, tool trials and corrections were performed. Keywords: Injection Molding, Top cover bearing, Nylon 6, Shrinkage factor, Easy flow advance
1. INTRODUCTION One well-liked and effective method for making plastic objects is the use of injection molding. Typically, this method uses molten polymer thermoplastics as the substrate. That is the order in which they originated and cooled. Infusion molding plastics are used in nearly every functional produced item in today's society, from food containers to vehicles.

4. COMPONENT STUDY AND 3D MODELLING The part is called a top cover bearing. Nylon-6 makes up the component substance, which has 30% glass packed in it. The part has a black color and a SGR 30 rating. The part has a volume of 298.35 cm³. The total mass of the components is 406.23 grams. The part has a density of 1.35 grams/cubic centimeter and an approximate volume reduction of 0.6%. The melting point is 285°C. Part that is produced is utilized in cars/automobiles.
Top cover bearing is used in the suspension assembly of the automobiles. Investigating the Nylon-6 substance that is used in the piece of equipment is the first step. The initial stage involves a thorough analysis of the substance specs and part dimensions (from 3D CAD). Choice of separating lines, drawing, shrinkage expense, optimal gate placements, runner layout, extraction of cores and cavities, ejected units, and ventilation systems are all included in design.
