The SUMMA engraving knife is a specialized tungsten steel blade suitable for SUMMA engraving machines. With stable and sharp cutting performance, it is widely used in industries such as advertising graphics, clothing heat transfer printing, traffic signs, etc. It is the core consumable for semi transparent cutting of thin film materials.
The SUMMA engraving knife is divided into three commonly used angles: 30 °, 45 °, and 60 °, with different angles corresponding to different processing scenarios. The 30 ° sharp blade has a slender and sharp edge, and is skilled at cutting fine small characters and complex hollow patterns. It is commonly used for clothing hot stamping film, with clean cutting lines and less burrs, meeting the needs of fine processing such as jersey numbers and clothing printing. 45 ° is a universal version with the widest range of applications. It is the mainstream choice for cutting ordinary stickers, body stickers, window stickers, and lightbox films in the daily production of graphic stores. The 60 ° blade has a sturdy body and strong impact resistance, suitable for thick materials and hard films. It is commonly used for cutting engineering reflective films and hard PVC films. When processing traffic warning signs, it is not easy to tip and has outstanding durability.
This tool is made of tungsten steel as the base material, with high hardness and good wear resistance. It can continuously engrave characters for a long time and maintain a sharp edge. The engraving operation only cuts the surface material without cutting the bottom paper, achieving semi transparent cutting. After processing, the pattern is easily peeled off, greatly improving production efficiency.
The SUMMA engraving knife is only suitable for thin film soft materials and is not suitable for carving hard boards such as acrylic, metal, and thick wooden boards. By selecting the right blade angle and combining it with appropriate pressure and speed, it can stably output high-quality patterns and text. In the fields of advertising signs, car body decoration, clothing printing, and safety label production, SUMMA engraving knives have become the preferred consumables for many processing practitioners due to their stable and reliable performance.
