Better crucibles & innovative sand core binders

Das in diesem Artikel erwähnte Unternehmen ist Aussteller auf der kommenden EUROGUSS.

In Hall 7A on the Foseco stand, we will be showcasing many of our latest innovations for non-ferrous and HPDC foundries, including Melt treatment, crucibles and refractory materials, innovative sand core binder solution for HPDC and die casting processes and applications.

Crucible: We are continuously improving our crucible technology to provide solutions that reduce energy consumption, increase output and improve production efficiency. The latest innovations that will be on show at EUROGUSS 2024 include Enertek ISO crucibles, which feature a highly insulating, proprietary Vesuvius coating that significantly reduces heat loss and energy consumption during induction melting or continuous casting, and Duratek crucibles, which are designed to last longer, especially in highly corrosive conditions. The latest Duratek Supermelt crucibles have superior fracture toughness, high temperature strength and oxidation resistance to ensure a long service life in aggressive aluminium melting processes.

Innovative sand core binders: A major limitation of the high pressure die casting (HPDC) process is that it is not possible to produce complex, hollow castings in large quantities in a cost-effective and sustainable manner. This is due to the difficulty of producing suitable cores. Standard sand cores cannot be used as they are difficult to remove after casting and do not provide sufficient surface finish. Salt cores are more suitable, but are expensive to produce and have other operational limitations.

In response to this challenge, we have developed the water-soluble binder and coating Wasco, which we will be presenting at EUROGUSS 2024. This innovative binder system has high flexural strength and has been successfully used in both liquid and semi-solid HPDC processes, even under difficult conditions. With an appropriate coating, Wasco-based sand cores can exceed 1000 N/cm² and are heat resistant up to 750 °C. Removal after moulding is simply done by rinsing with water, avoiding any risk of damage or cracking.
