MKS processing is a complex blast treatment involving multiple processes. It is a surface treatment technology specifically designed to solve issues related to resin molding defects. 【Examples of Release Defect Issues】 * Cavitation occurs. * The pin marks become larger during ejection. * It cannot be released without applying a release agent. → We will resolve the above issues all at once with the know-how we have cultivated so far and MKS processing! The slogan of the mold division at Fuji Seisakusho is "Always maintain a posture of working together with our customers to tackle problems!" This is because it is impossible to identify and solve the complex factors contributing to resin molding defects without the cooperation of our customers. We are in an era where resin materials are rapidly changing. It is assumed that molding defects will also arise according to the characteristics of the materials. We also accept urgent requests at any time, so please feel free to reach out if you are in need.

'α Treatment' is a surface treatment method that creates fine surface shapes through blasting. While surface treatment by blasting is often criticized for causing shape and dimensional changes, 'α Treatment' is okay! It uses very fine abrasives, which minimizes damage, and has the following characteristics: - Maintenance of sharp shapes such as cutting edges - Preservation of precise dimensions in molds with strict dimensional tolerances - Maintenance of coatings such as hard chrome plating It can be used not only for molds but also for tools like drills and cutters, electric bits, and mechanical parts like gears and sprockets. By improving sliding properties and enhancing the retention of lubricants through fine surface shapes, it can reduce usage amounts. It also has a peening effect, which can improve the durability of the material itself. 【Features】 - Improved release properties for rubber molds - Maintenance of edges, coatings, and plating - Enhanced wear resistance, fatigue strength, and sliding properties - Treatment of high-strength, high-brittleness materials is also possible For more details, please refer to the PDF document or feel free to contact us.

Alpha processing (patented) is a blasting process that uses extremely fine abrasives. It successfully minimizes changes in the shape and dimensions of the workpiece, surpassing conventional technologies to create a fine surface texture known as "microtexture" and a fine crystalline structure called "nanocrystals" through a peening effect. As a result, this treatment enhances "durability, fatigue strength, and sliding properties." It is suitable for maintaining areas such as: - Precision machining tools - Edges of punching tools - Surfaces of thin film coatings Since it improves the surface condition of the workpiece itself, there is no concern about peeling like with coatings. It also has a very high retention effect for lubricants and release agents, making it usable for mechanical components like cam slides and guide posts. **Features** - Sliding properties and anti-adhesion due to microtexture - Increased fatigue strength and hardness through nanocrystallization - Adaptability to various materials and fine areas - Can be processed without peeling even on coating film surfaces Free initial testing is currently available!

1. Where are you getting stuck? Where are you clinging? Is this not happening? ■ The rise near the PL surface of the insert made by electrical discharge machining ⇒ Discharge marks remain. Even if polished, the polishing marks become perpendicular to the release direction, which may lead to release failure. ◎ Countermeasure: Performing blast processing on the [insufficiently polished areas] will reduce the factors causing sticking and improve release properties. ◎ 2. Have you ever experienced sticking even though you are polishing to a [shiny mirror finish]? ■ To eliminate sticking, increase the grit of the polishing ⇒ If the surface roughness is too smooth (as it approaches a mirror finish), the cause of release failure changes from [sticking] to [adhesion]. ◎ Countermeasure: If [release failure does not improve even after polishing], adding fine irregularities through blast processing will improve release properties. ◎ [Design changes] [Review of molding conditions] ⇒ If defects are not improving, the [surface condition] may be the issue. Please consult with us once! [There may be such advantages too!?] ■ When release resistance decreases... - Cycle time becomes faster - Ejection slopes can be reduced - No sticking to the mold occurs

1. Let's increase the gates to address poor filling ⇒ Welds have occurred. Has this ever happened to you? ■ Increase the gates ⇒ The number of resin junction points increases with the number of gates, resulting in welds. By blasting the mold surface, it alleviates visually (the surface becomes matte, making it less noticeable) and expands the range of molding conditions (the fine unevenness reduces heat transfer from the resin to the mold, slowing the growth of the solidification layer, increasing injection pressure, and enhancing transferability, which alleviates weld depth). ◎ Result: Appearance defects are improved. ◎ 2. Adopting pin gates and submarine gates ⇒ Sink marks occur. Has this ever happened to you? ■ Increase the holding pressure setting. ⇒ The gate seal occurs quickly, and the filling density does not increase as desired. By blasting the mold surface, it expands the range of molding conditions (the fine unevenness reduces heat transfer from the resin to the mold, slows the growth of the solidification layer, increases injection pressure, and enhances the filling density of the resin up to the gate seal, which alleviates sink mark levels). ◎ Result: Appearance defects are improved. ◎ 【There might be such advantages!?】 - The range of molding conditions expands, stabilizing productivity - Warping and deformation are reduced - Injection pressure can be reduced
