Emulsifiable Fluid STABILIS 9445 Delivers 38% Coolant Savings and Improved Efficiency

December 22, 2025

The customer is a leading manufacturer of aluminium, zinc, and steel-alloy die-cast components, supplying parts to both automotive and industrial motor sectors. Their operations span CNC machining, die casting, and mould injection, requiring high stability, precision, and consistent lubrication performance across multiple production processes.

The Challenge


The manufacturer sought to improve coolant efficiency and reduce overall operating costs across their machining production lines. With a wide range of aluminium, zinc, and steel alloy components, they required a fluid that could deliver strong cooling performance, maintain stable emulsion quality, and support long tool life. Their goal was to lower consumption and optimize concentration levels.

MotulTech's Solution


To address their needs, MotulTech recommended STABILIS 9445, a high-performance water-emulsifying metalworking fluid designed for applications requiring superior cooling. STABILIS 9445 is particularly suited for machining casting-grade aluminium making it ideal for the customer’s aluminium and zinc die-cast components. Its advanced formulation combining mineral oil with ester-based lubricity delivers excellent cooling, strong lubrication, and stable emulsion performance.

The Outcome

Oil consumption was reduced by 38%, directly lowering operating costs across their machining lines. The coolant concentration requirement also dropped from 13% with the previous fluid to just 8% with STABILIS 9445, demonstrating its stronger cooling and lubricating performance. Throughout production, tool-life efficiency remained consistently high, supporting stable machining conditions and high-quality output.
