2020年12月3日，在 BITEC 召开的 “Additive Manufacturing Conference 2020” 上登场的 YN2-TECH 的中村 MD 和 Castem Thailand 的管理部长三野琢磨。向两位详细询问了两家公司的合作。

11948年作为糕点业（麦芽糕点）创业的 Castem，创业有50多年的历史，但其心态很年轻。
在为了自己公司进行点心制作机械的维护而开始的基于失蜡制法的零件制作领域中，通过磨炼技术成为了该制法的第一人（公司）。
另外，从2015年开始，致力于通过使用 3D 打印机等进行直接浇铸的制法。

そ另外，在泰国，在与 YN2-TECH 一起致力的 Additive Manufacturing（简称为 AM / 附加制造、层叠造型法）的领域，显示出了领袖的存在感。
YN2-TECH 的中村 MD 表示：“希望 Castem Thailand 对金属零件、以及想通过充分进行热分析制作的产品进行试制。另外，相反有时也接受设备咨询”，说明了两家公司的关系。

另外，“ Castem 在利用 3D 打印机处理金属这一点上，和各种企业合作制作金属产品。获得丰厚的收益。然后，进行市场营销，还进行宣传活动。该公司的那种想法值得学习。（中村 MD）”和该公司的存在起到了刺激作用。

另一方面，Castem 的三野先生表示：“ YN2-TECH 与汽车相关的制造企业组成了强大的合作伙伴，进行零件设计。通过与 YN2-TECH 合作，对于不了解失蜡模具制法的各位，从设计阶段就可以了解本公司擅长的制法。今后也想用我们的技术支持该公司”。

能应对多品种小批量的失蜡、金属注射、直接浇铸３种制法

失蜡制法：这是公元前就有的铸造技术之一，但由于 Castem 独自的研发，使仅能通过切削加工的高精度螺钉、齿轮等零件的制造成为可能。

失蜡制法的优势
① 可廉价制作模具且半永久
② 可批量生产形状复杂的产品
③ 也支持不锈钢等坚硬难以切削的金属材料
④ 也可应对以钛为首的高等级钢材

金属注射制法（金属粉末注射成形法 / MIM）：将粉末状金属粉和粘合剂（粘接剂）混合，将其注射到模具中制成的加工方法。

金属注射制法的优势
① 可以高精度和强度批量生产小物件、复杂形状的零件
② 形状自由度高，可制作锋利的刃口、异形孔、交叉孔等三维形状
③ 通过将多个部件一体化制造，可以降低成本
④ 尺寸精度高（金属注射的一般公差 ± 0.5%）
⑤ 实现相对密度 96 %以上
⑥ 可获得接近熔炼材料的机械强度
⑦ 可进行与熔炼材料同等的热处理、电镀等表面处理

直接浇铸：将失蜡的 WAX 置换为 3D 打印机造型的塑料进行金属化的制造方法。

直接浇铸制法的优势
① 比金属用 3D 打印机制作更便宜
② 无需模具即可制作
③ 可用多种钢材制作

中村 MD 表示，“今后两公司正在计划举办‘使用金属的 AM 解决方案’的研讨会”，言语中透露了其构想的一部分。

“我想用这次会议中介绍的 Additive Manufacturing 这种不使用模具的制法，做一些创新。（中村 MD）”<

YN2-TECH 的中村 MD 预定登上 2021年的武士亚洲杂志3月号和4月号。期待后续报道。
