My project slide ( PRODUCTION DEPT)

  1. 1. NASIR AZMIMECHANICAL DEPARTMENTROLL-NO 7071113121
  2. 2. DIPLAST LTD  Diplast Plastic Ltd. is considered to be one of the top ten companies of India due to its quality, technology, turnover, production capacity and various types of quality products. Many new innovations in plastics are being brought to India by Diplast Plastics Ltd.  The Unit was set up in the year 1972 and was inaugurated by none other than the Honorable ex-president of India - Mr. Giani Zail Singh Ji.
  3. 3. INTRODUCTION  Injection molding machine An Injection molding machine, also known as an injection press, is a machine for manufacturing plastic products by the injection molding process. It consists of two main parts, an injection unit and a clamping unit.  Injection molding machines can fasten the molds in either a horizontal or vertical position..
  4. 4. INJECTION MOLDING MACHINE FOLLOWING ARE THE BASIC PART OF INJECTION MOLDING MACHINE.  Injection cylinder  Drive unit  Hooper  Screw  Mold tools  Mold clamping cylinde
  5. 5. FOLLOWING ARE THE MAIN SYSTEM WHICH ISUSE IN INJECTION MOLDING MACHINE.  Injection system  Hydraulic system  Mold system  Clamping system  Control system
  6. 6. PPRC (POLY PROPYLENE RANDOM CO-POLYMER) This machine is generally use for making mold.  ELBOW  JUNCTION BOX  NAHNI TRAP  P- TRAP
  7. 7. OVER-VIEW OF INJECTION MOLDINGMACHINE
  8. 8. DUTIES $ RESPONSIBLITIESInstruction for the assistant supervisor of injection molding machine.1. Minimize the scrap and use the scrap simultaneously within 2-3 days when it is produce.2. Check quality and printing of fitting good.3. Man power handling and optimum utilization.4. Order execution in time.5. Check availability of raw material and to arrange for any short material.6. Arrangement of packing boxes whenever required.7. To check the insert availability and order well in advance.8. To absorbed the mold change time and reduce the mold change time as far as possible.9. In mold section maximum attention is to be paid to check efficiency of the worker.10. To make drawing of mold. so it can be use be use whenever in future.
  9. 9. APPLICATION OF INJECTION MOLDINGMACHINE Injection molding is used to create many things such as wire spools, packaging, automotive dashboards, and most other plastic products available today. Injection molding is the most common method of part manufacturing. It is ideal for producing high volumes of the same object. Some advantages of injection molding are high production rates, repeatable high tolerances, the ability to use a wide range of materials, low labor cost, minimal scrap losses, and little need to finish parts after molding. Some disadvantages of this process are expensive equipment investment, potentially high running costs, and the need to design moldable parts.
  10. 10. MOLD DRAWING Mold drawing structure.  Following are the basic part ;  Moving platters  Clamping cylinder  Cross head  Link  crosshead
  11. 11. MOLD OR DIA Generally Dia is use for making the different type of mold, according to our requirement. Such as Elbow, junction box,p- trap,coupler,etc
  12. 12. ORGANIC STRUCTUREPOLYVINYL CHLORIDE Poly(chloroethanediy)co mmonly abbreviated PVC, is a thermoplastic polymer. It is a vinyl polymer constructed of repeating vinyl groups (ethenyls) having one of their hydrogens replaced with a chloride group
  13. 13. ADVANTAGE $ DISADVANTAGE The greatest advantage of this process is its ability to produce single- piece injection moldings with highly complex interior geometries without secondary operations. Similarly shaped objects are usually made from aluminum castings, which can weigh 45% to 75% more than a comparable molding. The tooling also lasts longer than metal casting tooling due to the lack of chemical corrosion and wear. Other advantages include. Very good surface quality with no weak areas due to joints or welds High dimensional accuracy and structural integrity Not labor intensive due to the few secondary operations required Little waste Inserts can be incorporated
  14. 14. MOLDING DEFECTS Molding defects Injection molding is a complex technology with possible production problems. They can be caused either by defects in the molds or more often by part processing (molding) Once the equipment is set to successfully create the molded part, modern monitoring systems can save a reference curve of the cavity pressure. Molding Defects Ununiformly Burn mark Colour less
