M/s Maxwell Auto Components Private Limited is an IATF 16949:2016 & ISO 9001:2015 certified grey iron foundry 
that began operation in 2013 on a greenfield site in Coimbatore, Tamil Nadu – India. The initial construction of the foundry utilized technologies from global leaders such as Inductotherm Tri-Trak® furnaces for the melt shop and a DISA MATCH 20/24 matchplate molding machine with automatic core setter. The 30 t/h sand preparation plant for the molding line was based on a DISA SAM 3-40 turbine mixer with on-line controls.
Once in operation the foundry realized that the quality and consistency of the sand preparation system and the performance of the molding line could be improved with a sand cooler. After researching all of the available technologies a decision was made in 2018 to invest in a model MC-50 Simpson Multi-Cooler®. The sand cooler was produced in India by Wesman Simpson Technologies Pvt. Ltd. which is a joint venture company between Simpson Technologies Corporation located in the USA and Wesman Engineering Pvt. Ltd. located in India.
The Simpson Multi-Cooler was installed at the beginning on 2019 and after six months of operation Mr. C. Uvaraj – Plant Head / Foundry Operations of Maxwell said “we have scrutinized the first six months of operating data before and after the Simpson Multi-Cooler installation and the observations are below”:
- We have observed that the discharged sand moisture from the Simpson Multi-Cooler is at 2% and the sand temperature is now below 49° C (even during peak summer months) which has allowed us to reduce our scrap rate by 2%.
- We have reduced bond addition by 0.2%.
- We have completely eliminated having a water spray addition system to cool the temperature of the sand on the belt. Now the sand plant is cleaner and we have reduced our labor and maintenance costs.
- We have also noticed that the product change over having a higher sand to metal ratio, even in peak summer months was done seamlessly.
Mr. C. Uvaraj also said, “we are very satisfied with the performance of Simpson Multi-Cooler and also very satisfied with the after sales service rendered by its service personnel.”
The Simpson Multi-Cooler provides Maxwell Auto Components with pre-mixing of return sand variations, cooling of hot return sand to temperatures that allow maximum effectiveness of expensive bentonite and stable moisture to improve the performance of the sand mixer & automated controls. Sand discharged from the Multi-Cooler also creates less dust and improves the foundry environment while reducing the amount of housekeeping and maintenance. More than 35 Simpson Multi-Coolers have been made by Wesman Simpson Technologies Pvt. Ltd. in India and more than 800 are installed worldwide.
