[Effect] Increased surface hardness, reduced friction! Introducing the effectiveness and application examples of surface treatment and precision shot peening for press molds.
The precision shot peening surface treatment technology "OX-FSP treatment" has various effects, among which we will introduce five effectivenesses related to the improvement of the lifespan and formability of press molds. (1) Improvement of surface hardness (2) Reduction of friction (3) Reduction of galling and extension of mold life Improved wettability enhances the retention of press oil (4) Extension of coating film life due to increased adhesion strength of the film (5) Extension of mold life by imparting residual compressive stress (6) Longevity of cold working molds through "OX-FSP treatment" + "P-CVD" *For more details, please download the PDF or feel free to contact us.

basic information
"Precision Shot Peening 'OX-FSP Processing' is..." This method involves carefully selecting shot conditions based on the material, heat treatment, hardness of the product, as well as the usage environment and its countermeasures, and processing under appropriate conditions with the main objectives of improving fatigue strength and enhancing sliding properties. Compared to conventional shot peening, by reducing the media size to several micrometers to several millimeters, the injection speed can exceed 200 m/sec, allowing for tremendous injection energy even with the same amount of air (processing pressure). This enables the achievement of surface heat treatment effects, the application of high residual compressive stress, and the assurance of good sliding properties. "Features of OX" □ Capable of handling small lots (from 1 piece) to mass production □ Permanent test machines for prototypes □ Equipped with various inspection devices *We are available to provide explanations anywhere across the country.

Roughness Comparison of Deteriorated Roughness (Left) and Good Roughness (Right)
-
Shear surface evaluation The length of the shear surface when the 'OX-FSP treatment' is applied. It has increased by up to 48% with three types of processed materials.
-
Examples of application to press molds (untreated) Issues and processing objectives (1) Improvement of moldability (occurrence of wrinkles and cracks) (2) Improvement of mold life
-
Application example for press molds (after treatment) Treatment: 'OX-FSP treatment' + 'OX-POLISH' + coating Result: Wrinkles and cracks have disappeared, and moldability has improved. The lifespan of the mold is currently being tested.
