    FOUNDRY

    Soucy has two new facilities that manufacture high-quality gray iron, ductile iron, and ADI (austempered ductile iron) products, along with other specialized cast iron products. These two foundry facilities house Canada’s largest automated no-bake molding line. The foundry focuses on quality and innovation in molding, casting, fusion, core making and modeling.

    Alloys

    Gray Iron

    Gray iron is the most commonly used alloy, thanks to its desirable qualities and relatively low cost. A larger quantity of carbon is added to it to facilitate machining and welding, and to enhance resistance to corrosion and heat deformation. This type of alloy is malleable for production, however complex the part.

    Alloys

    Ductile Iron

    Adding magnesium to ductile iron gives it similar mechanical properties to those of steel, but at a lower cost. Soucy produces a wide range of ductile iron, which is more resistant than gray iron. Ductile cast iron, or spheroidal graphite, resists significant impacts and cracks and, as the name suggests, is ductile (expandable).

    Alloys

    ADI

    ADI is a special form of ductile iron obtained by heat treatment. It excels in applications where a combination of high mechanical properties and ductility is essential. It is used for parts that will be subject to major impacts, because it is resistant to cracking and fatigue.

    FUSION PROCESS

    Soucy inspects raw materials before each casting and each cast iron batch is analyzed and adjusted based on certain specifications. Facilities are equipped with independent induction furnaces for casting multiple classes of cast iron in a single day. Furnace autonomy allows the casting temperature to be controlled based on the specified characteristics of the parts to be cast. The electromagnet loading system loads a precise quantity of raw materials into the furnaces.

    Molding processes

    Soucy offers different types of molding tailored to client specifications and ADI, gray or ductile iron part characteristics, including the sizes and production volume required.

    Green Sand Molding

    For parts from 1 to 100 kilograms, green sand molding with aluminum match plates is recommended. This method allows for high-volume production of up to 150 molds an hour.

    Resin Sand (No-Bake) Line

    The process of resin sand casting with furan binder provides remarkable dimensional accuracy and surface finish. With this method, Soucy manufactures up to six molds per hour for cast iron parts from 50 to 8,000 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.

    Floor Molding

    This molding station is often used to develop new parts. Soucy also uses this process to produce unique or new parts, large quantities of parts, and parts with a complex geometry or large size. This method can be used to create cast iron parts weighing up to 8,000 kilograms.

    CORE MAKING

    Parts of all sizes and complex shapes

    Soucy also offers core making, which creates voids and complex shapes with a high degree of precision for cast iron parts of all sizes. Shell core making can produce a high volume of parts, while resin sand (no bake) core making is used for cores that measure up to about 30 cubic feet and weigh up to 1,300 kilograms.

    Green Sand Molding
    Resin sand (cold box) core making: 480 x 700 mm capacity
    No-bake
    Shell core 1100 x 900 mm
    No-bake core blower 500 x 500 mm
    No-bake core molding 2500 x 2500 mm

    FINISHING PROCESSES

    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.

    PATTERNSHOP

    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.

    CAPACITY

    Soucy’s two foundry facilities produce parts weighing from 1 to over 8,000 kilograms. The foundries are fitted out with six induction furnaces (four with six-ton capacity and two with three-ton capacity).
