Fonderie B. Marcoux manufactures custom castings in gray cast iron, ductile cast iron, aluminum and bronze. Depending on the alloy, we can produce parts weighing from 0.25 lb to 4,000 lb. Our daily production capacity can reach 16,000 lb of poured metal.
Parts are produced using green sand moulds or resin-bonded sand moulds with a catalyst. Our production consists mainly of raw castings. Particular attention is given to the quality and appearance of every part.

What types of parts can the foundry produce?
Our facilities can produce industrial castings in a wide range of sizes and weights. The applicable capacity depends on the alloy, part geometry, pattern, moulding process and project requirements.
The weight ranges should therefore be used as an initial reference. Final feasibility must be confirmed using the drawings, dimensions, quantities and technical specifications provided by the client.
What are the minimum and maximum casting weights?
Weight capacities vary according to the metal being poured. Gray cast iron and ductile cast iron allow us to produce the heaviest parts. Our aluminum and bronze capacities meet different industrial requirements.
| Alloy | Minimum weight | Maximum weight |
| Gray cast iron | 0.5 lb | 4,000 lb |
| Ductile cast iron | 0.5 lb | 4,000 lb |
| Aluminum | 0.25 lb | 450 lb |
| Bronze | 0.25 lb | 1,200 lb |
These figures represent our general production capabilities. A part within these weight ranges is not automatically suitable for production. Its shape, sections, tolerances and material requirements must also be evaluated.
What mould sizes are available?
Fonderie B. Marcoux uses moulds in several sizes. The smallest listed format measures 12 inches by 12 inches. The largest can reach 7 feet by 7 feet.
| Format | Dimensions |
| Smallest mould | 12 in × 12 in |
| Largest mould | 7 ft × 7 ft |
Several intermediate dimensions are also available. Our team can review an existing pattern and determine whether it can be used, adapted or modified for the production requirements.
What is the daily production capacity?
The amount of metal that can be poured each day depends mainly on the alloy. Gray cast iron and ductile cast iron offer the highest daily volumes. Different capacities apply to aluminum and bronze.
| Alloy | Daily production capacity |
| Gray cast iron | 13,000 to 16,000 lb |
| Ductile cast iron | 13,000 to 16,000 lb |
| Aluminum | 3,000 to 4,000 lb |
| Bronze | 8,000 to 10,000 lb |
These figures represent production capacity by weight. They do not necessarily correspond to a fixed number of parts per day. The number of pours varies according to the unit weight, mould size, project complexity and production schedule.
Which moulding processes are used?
Parts are poured in green sand moulds or moulds made with resin-bonded sand and a catalyst. The selected process depends on the part, metal, pattern and desired results.
The moulding process is selected during the project assessment. It can affect mould preparation, the resulting surface finish and the steps required before production.
Can Fonderie B. Marcoux manufacture or modify a pattern?
We offer pattern manufacturing services. Patterns can be made from wood, plastic or aluminum according to the requirements of the project.
Our team can also repair or modify an existing pattern. This may be useful when a part must be reproduced, adapted or returned to production without creating an entirely new pattern.
For more complex projects, we work with a pattern shop located near our facility. It can manufacture patterns using traditional methods, computer numerical control equipment and 3D drawings.
