Kev tsim kho tshuab ntau yam thiab kev tsim kho tshuab yog qhov tseem ceeb tiam siab ntawm kev tsim kho tshuab, ua rau muaj kev pib siv ntau tshuab hauv ntau cheeb tsam xws li kev tsim kho tshuab ua tshuab, siv khoom siv hluas, khoom siv rau kev kho mob, thiab kev sau nti. Lawv tsis yog tshuab tsuas; lawv yog qhov tshuab tseem ceeb uas tau tsim los ntawm kev tsim kho tshuab kom zoo ib txhis thaum muaj kev siv ntau heev, tab sis tsis txhob muaj kev puas tsuaj rau cov khoom uas tsim tawm. Qhov sib txawv feem ntau nyob rau hauv kev siv: "tshuab" feem ntau hu rau tshuab siv rau kev tsim kho tshuab, tsim kho tshuab, lossis tsim kho tshuab metal, uas siv zog loj los tsim kho tshuab sheet metal lossis solid billets, thaum "moulds" (lossis molds) siv rau kev tsim kho tshuab xws li injection molding lossis die casting, uas siv plastic lossis metal uas tau hluas los tsim kho tshuab hauv lub cav. Kev tsim kho tshuab precision dies thiab moulds yog qhov kev tsim kho tshuab uas muaj ntau cheeb tsam, uas pib los ntawm kev siv CAD/CAE design, suav nrog kev sim tshuab tshwj tsis txaus siab ntawm kev dhau ntawm khoom, kev sov, thiab kev puas tsuaj rau kev paub thiab tshem tawm qhov chaw uas yuav muaj kev puas tsuaj rau cov khoom tshuab tshwj tsis. Cov khoom siv, xws li hardened tool steels (xws li H13, S7) thiab carbides, tau raug xaiv kom muaj kev tso tawm zoo, kev nyab xeeb, thiab kev nyab xeeb hauv khib. Kev tsim kho tshuab siv cov tshuab tseem ceeb tiam siab, xws li high-speed 5-axis CNC milling rau kev tsim kho tshuab 3D ntau yam, Electrical Discharge Machining (EDM) rau kev tsim kho tshuab ntau yam thiab kab ntsug uas tsis tuaj yeem tsim los ntawm kev tsim kho tshuab, thiab kev grinding kom muaj kev sib piv zoo thiab kev nyab xeeb hauv micron. Ntxiv mus, cov tshuab no muaj kev tsim kho tshuab ntau yam hauv nws—cooling channels rau kev coj khib, ejector systems rau kev tshem tawm khoom, thiab feem ntau muaj kev tsim kho tshuab ntau yam xws li slides, lifters, thiab unscrewing mechanisms los tsim kho tshuab undercuts thiab threaded features. Kev tshawb xyuas tshuab tshwj tsis tiam siab los ntawm kev tshawb xyuas thiab kev hloov kho tshuab yog qhov tseem ceeb kom paub meej tias tshuab no tsim kho tshuab khoom uas muaj kev nyab xeeb hauv daim duab, tsis muaj kev puas tsuaj hauv daim duab, thiab muaj kev nyab xeeb hauv kev ua haujlwm. Kev investment rau hauv precision die lossis mould yog loj, tab sis nws muaj txiaj ntsig tshaj plaws rau kev tsim kho tshuab, kev nyab xeeb hauv khoom, thiab kev nyab xeeb hauv kev tsim kho tshuab, ua rau nws yog qhov tseem ceeb tiam siab hauv kev tsim kho tshuab ntau yam.
