Gray iron is the most commonly used alloy, thanks to its desirable qualities and relatively low cost. Grey iron, or lamellar graphite cast iron, has excellent thermal conductivity, good vibration absorption and very good machinability.
Soucy produces a wide range of ductile cast irons. Ductile cast iron, or spheroidal graphite cast iron, is much more mechanically resistant than grey cast iron. This type of cast iron is obtained by the addition of magnesium. According to the grade used, ductile cast iron can be impact resistant at low temperatures, and resistant to creep and oxidation at high temperatures. It can also have the proper combination of mechanical strength and ductility for your application.
ADI is a special form of ductile iron obtained by heat treatment. This type of cast iron has a very strong combination of toughness and mechanical strength due to its very fine microstructure called "ausferrite". ADI cast iron is the ideal choice for parts subject to high cyclic stress due to its fatigue strength. It is also a type of cast iron that is more resistant to abrasion than other types of graphite cast iron.
Soucy can also produce other types of alloys according to your needs.
Soucy’s facilities are equipped with independent induction furnaces, allowing the casting of multiple classes of cast iron in a single day. The electromagnet loading system allows a precise allocation of raw materials into the furnaces. Soucy conducts a chemical analysis of each casting and each one is adjusted according to its specifications.
Soucy offers different types of molding tailored to client specifications and to the characteristics of the part according to its sizes and production volume required.
High Pressure Green Sand Molding
A highly automated production line with a horizontal parting line produces parts ranging from 0.5 to 100 kilograms. This method can produce a high volume of up to 150 moulds an hour. The state-of-the-art sandblasting facility ensures a very high consistency and quality of green sand, a key factor for this type of moulding.
Resin Sand (No-Bake) Line
The process of resin sand casting with furan binder provides remarkable dimensional accuracy and strength for solid parts. With this method, Soucy manufactures up to six molds per hour for cast iron parts from 50 to 5,000 kilograms with high repeatability and consistency. Molds can reach sizes of up to 2 x 2.6 x 2 m for automated lines, and 1.25 x 1.5 x 1 m for semi-automated lines.
This molding station is often used to develop new parts. Soucy also uses this process to produce very large parts (exceeding 2 m x 2 m). The only limit for this moulding station is that the part including its feeding system must weigh less than 10,000 kg.
Parts of all sizes and complex shapes
Soucy's facilities use several distinct core processes. Core-making allows the creation of voids and complex shapes with a high degree of precision for cast iron parts of all sizes. Whether it is by the "cold box" process, the "Shell" process or the "No-bake" process, our experts will use the type of moulding that minimizes tooling costs while ensuring the quality of the parts.
Soucy has two robotic grinding systems for small parts. For the resin sand molding process, Soucy also offers manual grinding on a well-organized unit.
Soucy offers services to reproduce, repair and modify existing models. With modern facilities and skilled modelers, the company designs casting systems and models tailored to each product in order to obtain top quality every time.
Soucy’s two foundry facilities produce parts weighing from 0,5 to over 10,000 kilograms. The foundries are fitted out with five induction furnaces (four with six-ton capacity and one with three-ton capacity).
