Our unique technology, "OX-FSP treatment," has various effects, among which we would like to introduce five benefits related to the improvement of the lifespan and moldability of die-casting molds. (1) Significant extension of mold lifespan through the application of compressive residual stress, contributing to heat crack prevention due to a remarkable improvement in half-value width. (2) Reduction of galling and extension of mold lifespan, with improved wettability leading to more uniform spraying and retention of release agents. (3) Improved flowability and release properties due to a special plateau structure, resulting in reduced defect occurrence due to enhanced moldability, decreased porosity due to improved release and fluidity, and enabling thin-walled molding through enhanced gas venting and flow characteristics. (4) Increased longevity and improved moldability in magnesium casting. (5) Significant improvement in resistance to dissolution through a composite treatment with the special coating "OX-COAT." *For more details, please download the PDF or feel free to contact us.

We will introduce five clear effects of improving mold and product quality by combining micro-particle precision shot peening "OX-FSP treatment" and oxo special polishing "OX-POLISH." (1) Reduces the occurrence of product surface peeling (2) Reduces the occurrence of voids and shrinkage cavities (3) Suppresses the occurrence of seizure and galling (4) Measures against melting loss (5) Delays the occurrence of heat cracks (heat checks) By refining the crystal grains of the mold, it delays the oxidation of the grain boundaries. It is possible to implement measures against thermal fatigue through residual compressive stress and increased hardness. *For more details, please download the PDF or feel free to contact us.

Here is a case study on extending the lifespan of hot forging molds. After removing the discharge abnormal layer through OX-FSP treatment, we further enhance fatigue strength. The surface becomes nanocrystalline, leading to an expected extension of lifespan. Additionally, the special dimples enable a stable supply of release agent, improving mold release. This imparts high residual stress and high hardness. 【Effects】 ■ Durability shot count: Improved by approximately 150-200% ■ Suppression of heat crack occurrence due to nanocrystallization → Significant extension of mold lifespan ■ Stable supply of release agent due to special dimples → Improved mold release and extended mold lifespan ■ High residual stress and high hardness imparted → Significant improvement in mold fatigue strength ■ Removal of discharge machining altered layer → Elimination of crack initiation points and extension of lifespan *For more details, please refer to the PDF document or feel free to contact us.

Here is an example of processing for "pierce punches." PVD treatment was combined with OX-FSP treatment. The punch lifespan improved from 20,000 shots to 100,000 shots. This improves the adhesion of the coating, enhancing the durability and longevity of the punch. [Case Overview] ■ PVD treatment combined with OX-FSP treatment ■ Reduces punch galling and improves durability ■ Results: Punch lifespan improved from 20,000 shots to 100,000 shots *For more details, please refer to the PDF document or feel free to contact us.
