pellet mill ring die for making feed pellet
Advantages: 1.?The?specialized?steel?forge?process?provide?high?quality?steel?forges.? 2.?With?the?15years?experience,?the?dies?made?by?advanced?special-purpose?gundrill,?ensuring?precise?size?of?die?holes. 3.?The?specialized?key?heat-treating?process?is?carried?out?by?advanced?heat-treating?equipment?such?as?vacuum?furnace. 4.?The?professional?design?and?marketing?experience?guarantee?shape?and?depth?of?die?,hole?and?hole-opening?rate,?which?can?meet?the?different?requirements?of?poultry?and?livestock?feed?and? aqua?feed.Thus?greatly?improve?the?quality?and?high?efficiency?of?pelleting. ?5. ?Perfect?sales?and?after-sales?service?meet?requirement?of?user. ? Features of?our?production?process: 1. Material?refining?technology,fewer?impurities, high?purity, largely?reducing?harmful?elements?content (such?as?elements?S,P?),?thus?comprehensive?mechanical?performance?of?material?is?raised. 2. Through?roll?forging,?material?is?processed?and?strengthened?and?material?fibre?is?complete?and? uniform,?which?increases?integrated?mechanical?performance?of?material. 3.?FDSP?Company?has?the?world?advanced?forging?equipment?and?technology,electronic?data?processing?systems?and?perfect?quality?control?system. 4. Ring?die?blank,generally?chromiumalloy?roll?forgings,?some?factories?use?45?ordinary?carbon? steel. 5. Hardness?of?blank?must?be?controlled,?ranging?from?HB170?to?HB220. If?the?hardness?is?too?high, the?drill?is?easy?to?break?and?happens?with?die?hole?when?drilling.?If?hardness?is?too?low,?the?surfacefinish?of?die?hole?will?be?not?good. ?6. In?order?to?control?blank?inner?material?uniformity,?every?blank?must?be?carried?out?with?fault? detection,?which?can?avoid?defects?such?as?flaw,?pore-free,crackle?and?inclusions?etc. ?7. After?machining?and?heat?treatment?process,?hardness?of?ring?die?can?be?up?to?HRC?52-58 (inner?diameter?less?than?350mm), HRC50-56 (inner?diameter?more?than?350mm), more?wearable? and?anti-corrosion. ?8. In?order?to?control?hardness?uniformity?of?ring?die?after?heat?treatment,?we?choose?more?than? three?points?in?each?part?of?trisection?of?peripheral?direction?to?test?hardness?and?take?average. The?difference?of?hardness?value?between?each?part?should?not?be?higher?than?HRC4. ?9. According?to?the?principle?of?metal?material?science?combined?with?gas?quenching?and?C, Cr, Mn, Ni, V?elements?content?is?optimized,?forming?the?standard?of?ring?die.
