Hybrid: A combination of mineral casting and various structural materials.
EPUFILL
It has excellent compatibility with castings and can bodies!
If you're interested in mineral casting but have concerns such as: → Is the strength insufficient? → Is there a high initial investment (mold cost)? → Isn't it cumbersome to replace castings and can bodies from scratch? We recommend RAMPF's hybrid structure "EPUFILLⓇ". By simply filling the gaps in castings and can bodies, you can add the excellent damping and thermal properties characteristic of mineral casting. ◎ You can ensure strength with castings and can bodies. ◎ Since you only need to fill the gaps in the structure with mineral casting, the mold cost is zero. ◎ You can use existing structures, eliminating the hassle of new designs. Furthermore, if you choose the DIY kit "EPUSELF" with good fluidity, there's no need for a vibration table! You can fill it on-site at your company (however, please note that the filling amount and the shape of the structural gaps may vary, so we recommend a preliminary meeting). While new designs will be necessary, it is also possible to achieve an "ideal hybrid structure" through structural analysis by combining "lightweight thin-walled castings + the performance of mineral casting." A new form that has never existed before will be created by your hands. Please feel free to contact us!
