18 CASTING PLANT:This plant provides castings in raw form for the engine plant to do machining operations on it.PPC gives monthly plan to casting shop. The casting shop takes daily target from customer shop i-e cylinder head machining shop. Then according to their requirement they generate their own schedule. They determine that how many castings & how many shot blasts (finished according to C/H machining shop), the casting shop will manufacture.Raw Materials:Following RM’s are received by casting shop from general stores by I. R. Aluminum ingots, RCS sand. There are three types of castings done in this plant they are:
19 LOW PRESSURE DIE CASTING: This type of casting is done in only Atlas Honda in Pakistan. There is no other industry using this type of casting process. Here, four parts are made:• Cylinder Head of CD 70• Cylinder Head of CD 100• Cylinder Head of CG 125• Cylinder Head of CG 125 DeluxeDetails of processes & machines used
20 Melting of Al ingots:First of all, raw aluminum alloy in form of ingots is melted in MELTING FURNACE.The furnace is an automatic controlled furnace which melts Al ingots at 7300CGBF:A fork lifter takes the liquid aluminum out of the furnace and pours it into Gas bubbling filtration machine which degassing molten Al i-e removing air/hydrogen contents.
21 LPDC:After GBF, the liquid aluminum is poured into the LPDC machine where dies are available. The liquid metal goes into the die to form the casting. The pressurizing time for the die is 120 seconds. After this, water is passed through the die to cool the aluminum for 15 seconds. There are sand pores placed inside the die for giving shape to the casting.Chipping:After this, the casting is removed from the die and sand pore is removed by a process called sand breaking on chipping machine.
22 Gate cutting:Then gate cutting machine is utilized to cut the gate with the casting. The gate is the extra material attached with the casting which is formed when liquid aluminum entering the die is solidified. Thus, gate represents the pathway for the liquid aluminum and has to be removed.Tig Welding:Then welding is performed on Tig Welding Plant. This is done only when required. It is mostly not used. Workers then perform finishing of the casting by dry grinders.
23 Heat Treatment process: Heat Treatment process is then performed to strengthen the material of the cylinder head casting. Quenching is done by heating the casting up to 500 degree centigrade and then immediately dipping it in water at temperature of 50 degree centigrade.Shot blasting:Next, shot blasting machine is used to coat the part with steel. In shot blasting machine, steel balls are fired on the casting with high momentum. They strike the part and leave their impact on the casting in form of steel coating. The part is now ready to deliver.
24 Core preparation section: There is another section in LPDC where dies are coated with special material and their service is performed. The sand cores used in the dies are also prepared in a machine. This machine utilizes special sand called TSC to prepare sand cores. This sand is imported from Malaysia and Taiwan at cost of rupees 20 per kg through HONDA TRADING. Sand is first roasted at 300 degree centigrade and then compressed to a compact form to give it desired shape
