We will introduce terms related to molds, as well as surface treatments and case studies that can solve molding troubles.
Terms related to molds include the following: [Mold-Related Terms] - Shot: The unit amount of molten resin injected from the injection port in injection molding. - Gate: The part within the mold where molten resin flows in during injection molding. - Ejector Pin: A pin that moves with the operation of the mold to remove the molded product from the mold. - Laminated Plate: An element that constitutes the mold, consisting of multiple stacked plates. - Drilling Process: One of the manufacturing processes for molds, involving creating holes in metal plates, etc. - Heat Treatment: A process of heating and rapidly cooling metal materials to extend the durability and lifespan of the mold. - Wear: Refers to the wear that occurs due to the use of the mold, which affects the mold's lifespan. - Casting Mold: A mold used in casting. - Design Drawing: A drawing created by the designer in the mold design process. - Assembly: The process of assembling the various components of the mold. - Mold Surface Treatment: A technique that can improve wear resistance or release properties on the surface of the mold. These are basic terms that people involved in mold manufacturing, operation, and maintenance should be familiar with. Below, we will introduce surface treatments.

basic information
The surface treatments for molds commonly used include: 1. Plating 2. Anodizing 3. Fluororesin coating 4. DLC coating 5. Mirror finishing 6. Matte finishing However, conventional surface treatments often do not meet the desired functions such as strength and release properties, and improvements may not be achieved as expected. Our original surface treatment, 'BICOAT', realizes the combination of "strength + anti-adhesion and slip properties comparable to fluororesin coating." [Main types of BICOAT(R)] ■ NYK-01 - Surface treatment that combines a nickel-based metal film with fluororesin. ■ NOO-01 - Surface treatment that combines a chromium-based metal film with fluororesin. ■ TYS-03 - Surface treatment that fuses fluororesin into a chemical film reacted with iron ions in the metal substrate. ■ NYN-11 - Surface treatment that combines fluororesin with an alumina film. ■ CTT-200 - Surface treatment that combines siloxane-based resin with a metal film.
