Can die lubricants contribute to smoke in a foundry?

The main source of smoke is usually the plunger lubricant. These are usually organic compounds and there is a tendency to overfeed these products. High efficiency and low smoke plunger lubricants can minimize the smoke in a foundry. Die lubricants are usually water-based products and therefore are not major contributors of smoke. Some oil-based die lubricants can produce smoke but are typically fed at very low dosages and so the quantum of smoke produced is not significant.
