In resin (plastic) molding, issues such as sink marks, weld lines, ejector pin marks, and adhesion to molds frequently cause defects. To resolve these challenges, we developed surface modification technologies MKS Treatment® and its advanced version GMT Treatment® using air blast technology. These technologies create precise surface textures on molds, improving resin flow and release performance.

■ Features
Optimization of Resin Flow: Creates uniform surface textures ranging from nanometers to a few micrometers on mold surfaces, minimizing the contact area between the resin and the mold. This prevents premature cooling of the resin, enabling smoother flow.
Improved Release Performance: The non-directional surface structure reduces adhesion caused by resin shrinkage, ensuring smooth release after molding.
High Versatility: Enables optimal surface modification tailored to mold shapes and purposes, making it adaptable to various molding environments.
Advanced GMT Treatment®: Building on MKS Treatment®, GMT Treatment® adds further functionality, delivering exceptional results in high-precision molding environments.

■ Capabilities
Processing Precision: Surface modification precision ranges from nanometers to micrometer levels.
Applicable Targets: Molds for resin molding.
Compatible Materials: Resin, glass, ceramics, and other brittle materials.

■ Case Studies
Automotive Parts Molding: Successfully suppressed ejector pin marks and weld lines, enhancing appearance quality.
Home Appliance Components: Improved release performance, reducing molding cycle time.
Medical Device Parts: Suppressed warping caused by resin shrinkage, ensuring precision.
