- Transparent acrylic has light transmittance comparable to glass, but the density is only half that of glass. In additionally, it is not as fragile as glass, and even if broken, it does not form sharp fragments like glass.
- The abrasion resistance of acrylic is close to that of aluminum, with good stability and resistance to various chemical corrosion.
For above the acrylic molds, will need at least 3 sliders, and all finishing is directly by CNC machining! In addition, the steel needs at least H13 with hardness HRC45-48, thus can guarantee the final mugs transparency!
