JP Caster generally uses higher standard caster grinding screws in the custom casters. JP Caster s always start with manufacturing high standard casters
塞打螺丝也叫轴肩螺丝，止动螺丝、止动螺栓、制动螺栓等；塞打螺丝是和螺栓拉杆配合使用，主要是用于控制三板模中的定模座板，流道推板和定模模板之间的开模行程的模具配件。因为可设置到模具的分型面上，故能使模具设计小型化。该类产品硬度高、韧性好、耐磨性和耐热性***，适用于精密模具，可显著提高其使用寿命，特别是精密模具的热形变得到了有效的控制，适用于高温作业环境的模具。塞打螺丝构成属性材质：SCM435，硬度：33～38HRC。
Plug screw is also called shoulder screw, stop screw, stop bolt, brake bolt, etc.; plug screw is used in combination with bolt pull rod, mainly used to control the die setting plate in three plate die, Die accessories between runner push plate and die setting template. Because it can be set on the parting surface of the die, the die design can be miniaturized. This kind of product has high hardness, good toughness, wear resistance and heat resistance. It is suitable for precision mould and can significantly improve its service life. Especially, the hot forming of precision mould has been effectively controlled and it is suitable for mould in high temperature working environment. Plug screw constitution property material: SCM435, hardness: 33-38hrc.
