Inquiry (采购产品): POLYESTER MELT PUMP KASH INDUSTRIES PVT.LTD.DELHI,INDIA E-mail :- kashindustries@yahoo.com Date 22” AUG. 2006 Dear sir We are the manufacturer of polyester monofilament for zipper industry. OUR NEW MONOFILAMENT LINE FITTED WITH BARMAG MAKE 70 cc/rev MELT PUMP. Our existing 70cc MELT PUMP Type Barmag ZP525. THIS PUMP IS RUNNING WITH 21 rpm FOR 112 kgs/hrs PRODUCTION RATE. FROM BOTH PUMP WE ARE GETTING 224 kgs/hrs . THIS MELT PUMP HAS 15 teeth GEAR SET. MONOFILAMENT BEING PRODUCED FROM THIS LINE HAS SOME PROBLEM 1-DIAMETER OF MONOFILAMENT IS OVAL (0.74mm – 0.76mm or 0.75 – 0.77 LIKE THAT) that has to be circular. 2-DIAMETER OF A SINGLE FILAMENT SHOWS VARIATION WHEN IT CHECKED ALONG WITH ITS LENGTH; IN DIFFERENT PLACES. SOMEWHERE IT IS 0.74mm , SOMEWHERE 0.78mm , SOMEWHERE 0.77mm, SOMEWHERE 0.76mm. 3-VARIATION OF DIMENSION OF zipper COIL WHEN CHECKED IN COILING SECTION. SOMETIME DIMENSION ARE OKEY, SOMETIME DIMENSION DECREASES SOMETIME INCREASES WITHIN THE SAME COILING MACHINE. EVEN IN SAME BOBBIN. FOR THIS PROBLEM SOMEBODY IN INDIA TOLD US TO CHANGE MELT PUMP TO 40 or 45 cc/rev AND TRY TO DECREASE PRODUCTION RATE SOMEWHERE AT 175 to 200 kgs/hrs FROM BOTH PUMPS, because this is may be due to diameter variation of monofilament. HE ALSO TOLD TO INCREASE NUMBER OF GEAR TEETH FROM 15 to 22 OR MORE. THIS WILL HELP TO INCREASE UNIFORM DELIVERY OF MELT. SO IN THIS MATTER WE WANT YOUR SUGGESTION CAN WE USE 40 or 45 cc/rev PUMP WITH 22 or MORE GEAR TEETH COMBINATION. IF THIS CAN HELP TO INCREASE UNIFORM DELIVERY OF MELT AND MORE CIRCULAR DIAMETER OF MONOFILAMENT PLEASE SEND US QUOTATION Regards GOVIND JOSHI kashindustries@yahoo.com **** Hidden Message ***** GOVIND JOSHI 110033 Company: KASH INDUSTRIES PVT.LTD.DELHI,INDIA E-mail: kashindustries@yahoo.com **** Hidden Message ***** kashindustries@yahoo.com
