First, a rectangular solid material is appropriately processed by cutting or the like, and a recess corresponding to the resin flow path 3 and the cavity 4 is formed. Next, a layered (film-like) surface layer 17 is formed on the lower surface 16 which is the surface on which the recess is formed, using a suitable method among known methods.
- the resin mold used for sealing the chip 12 mounted on the substrate 11 has been described as an example.
- the invention is not limited to this, and is used for forming a molded body by curing the flowable resin in a state where the flowable resin is filled in the cavity, such as general transfer molding, injection molding, compression molding, etc.
- the present invention can be applied to the resin mold for molding.
- the main body parts 8 and 15 may be made of a normal resin mold material, for example, a steel-based material such as tool steel or a cemented carbide. Then, as in the embodiments described above, compressive residual stress can be caused to exist in the surface layers 10 and 17 by appropriately determining the thermal expansion coefficients of the main body portions 8 and 15 and the surface layers 10 and 17. it can.
- the low adhesion material according to the present invention and a resin mold using the same were described. Not limited to this, low adhesion materials may be used for applications other than resin molds.
- the application is another application that requires low wettability to a substance having basicity, and also requires abrasion resistance and impact resistance.
- the low adhesion material according to the present invention can be used for coating or the like of a portion of a member or the like to which fluid resin contacts.
- the low adhesion material according to the present invention is a substance other than resin and having basicity. In addition to low adhesion to quality, it can be used in applications where abrasion resistance and impact resistance are required.
- a low adhesion material can be used as a material having a function of preventing the adhesion of soils made of organic matter. Specifically, it may be used as a material for construction materials, baths, sanitary ware, and similar devices used for the outer wall of buildings and the like.
- the low adhesion material according to the present invention may be used as a material for coating the surface of a member used for these applications.
- the above-mentioned low adhesion material 3 can also be used as an antifouling material having a function of preventing the adhesion of dirt made of an organic substance.
