Casting stronger ties A joint venture between Asahi Organic Chemicals Industry Co. Ltd in Japan and Modi Rubber Ltd in India, Asahi Modi Materials Private Limited (AMM) was set up in November 2012 for the manufacturing and selling of high quality resin-coated sand in India. Asahi Modi Materials has already established a test plant with a capacity of 180 tons/month in Ahmedabad and has been providing samples to foundry, automotive companies for trials since August 2013. The JV firm is currently in the process of setting up a resin-coated manufacturing plant with a production capacity of 4000 tons/month in Jhagadia, District Bharuch. The plant is slated to begin operations by October 2014. Advantages of AMM Asahi Organic Chemicals Industry Co. Ltd.(AOC) Products Resin-coated sand formulations Top market share & experience of more than 35 years in Japan Resin-Coated Sand (RCS) Phenolic Resin for Casting All Japanese automotive & over 700 Japanese casting manufacturers are AOC s clients. As a result, we have more RCS formulations. Raw material (Phenolic Resin and HQ Silica Sand) Solid Phenolic Resin from AOC HQ-washed Silica Sand High strength type Low expansion type High cure type And so on High silica content High purity Good Shape And so on Solid Phenolic Resin Mixing Technology Knowledge of RCS formulations HQ-washed Silica Sand AMM-RCS

High strength & good flow ability Improves the broken core problem in molding and casting TECHNOLOGY AMM RCS No broken core! No sand drop! Sand drop broken core in setting Broken core in casting Sand in casting RCS ability Item AMM-RCS Shell core weight 46.6g 44.3g 60 This picture is for reference only Shell core Volume Packing density 30cm 3 1.55 This picture is for reference only 30cm 3 1.48 Bending Strength ( kgf / cm 2 ) 50 40 30 20 10 0 1.6 AMM-RCS 2.5 AMM-RCS Resin Content Fig. Bending Strength Advantages Reduces a variety of defects related to broken core & sand drop.

Easy shake-out RCS Developed for Aluminum castings, offering excellent collapsibility TECHNOLOGY AMM RCS Molding Casting Shake-out Good collapsibility Poor collapsibility Advantages

Anti veining RCS Prevents veining and hot tears caused by thermal expansion TECHNOLOGY AMM RCS Molding Casting Shake-out Non-veining Veining Advantages Able to cast by shell core without applying coating in some case.

Hollow core RCS For improved quality of hollow core TECHNOLOGY AMM RCS Molding (The metal pattern is flipped over) Return to sand tank Re-use of RCS is good. Return to sand tank Re-use of RCS is not good. Hollow core Even surface Uneven surface Advantages Improved collapsibility of the tear casting Reduction of gas defects of the casting Weight saving of shell core Reduction of RCS consumption

Resin-coated artificial sand Asahi Organic Chemicals Industry Co., Ltd. NATURAL SILICA SAND RCS ARTIFICIAL SAND RCS Picture Sand form Square Spherical Sand mold surface Coarse Smooth Mold strength Low High Amount of required resin binder (Need to display the same level of strength) Many Little Filling performance in the metal pattern Low High Heat expansion of mold High Low Scheme Metal Metal Sand Mold Sand Mold Surface of casting Advantages Reduces a variety of defects gas, veining and so on. The surface of the casting is smooth.
