"Pitamold" is a sealing material that exhibits excellent adhesion in self-hardening molds, preventing leakage of molten metal from the mold joint surfaces. It is resistant to changes in temperature and humidity, allowing it to maintain sealing performance over long periods, making it suitable for year-round use. With minimal stickiness, it significantly contributes to improved work efficiency, and its white color makes it easy to recognize, which helps reduce work errors. 【Features】 ■ Excellent adhesion ■ Excellent storage properties ■ Minimal stickiness ■ Solvent-free type, so it has no irritating odor *For more details, please refer to the PDF document or feel free to contact us.

We handle "casting aggregates/casting sand" for sand casting at our company. We offer a wide variety of sands, including silica sand, artificial sands like NE Sand, Sun Green, and Espal, as well as specialty sands like Chromite Sand, allowing us to meet our customers' needs. To improve the impact of crystalline silica dust from silica sand on the working environment, more companies are switching from silica sand to artificial sand. 【Products We Handle】 ■ Silica Sand ■ NE Sand (Artificial Sand) ■ Sun Green ■ Espal ■ Chromite Sand (Specialty Sand), etc. *For more details, please refer to the related links or feel free to contact us.

Our company manufactures sand suitable for the furan mold by removing impurities such as clay and adjusting the particle size distribution. Furan self-hardening molds are one of the representative molding methods widely used in sand casting in Japan. Additionally, they exhibit high strength, have good fluidity of the mixed sand, and are easy to adjust the usable time. 【Features of Furan Molds】 ■ One of the representative molding methods in sand casting ■ Exhibits high strength ■ Good fluidity of mixed sand ■ Easy to adjust usable time ■ Hardens through a dehydration condensation reaction *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our "Alkaline Phenol Self-Hardening Molds." Since it does not contain nitrogen or sulfur, it does not adversely affect the structure of cast steel or cast iron. It can be molded using fine sand, and even without a coating, it achieves a good casting surface. This molding method has features not found in traditional sand molds. The combination of the alkaline phenol molding method and the highly crush-resistant Espal not only improves the yield of recycled materials but is also suitable for producing high-quality castings. 【Features】 ■ Does not contain nitrogen or sulfur ■ Does not adversely affect the structure of cast steel or cast iron ■ Can be molded using fine sand ■ Achieves a good casting surface even without a coating *For more details, please refer to the related links or feel free to contact us.
