Qib 12.9 ISO7379 Allen taub hau lub xub pwg ntsia hlau

Main siv: Plug screws (ISO 7379) kuj hu uaallen taub hau lub xub pwg ntsia hlau. Plug screws yog siv ua ke nrog bolts thiab khi pas nrig, thiab feem ntau yog siv los ua pwm fittings rau kev tswj cov pwm qhib stroke ntawm pwm rooj zaum phaj, runner pusher phaj thiab pwm template nyob rau hauv peb-phaj pwm. Vim tias nws tuaj yeem raug teeb tsa rau qhov seem ntawm cov pwm, nws tuaj yeem ua rau pwm tsim me me. Cov khoom no muaj siab hardness, zoo toughness, hnav tsis kam thiab kub tsis kam, haum rau precision pwm, uas yuav ua tau kom lawv cov kev pab cuam lub neej, tshwj xeeb tshaj yog cov thermal deformation ntawm precision pwm tau zoo tswj, haum rau pwm nyob rau hauv high kub kev khiav hauj lwm ib puag ncig.
