As-Cast Design Features Did you know that Signicast is capable of casting other design features into components with little to no secondary operations? All rights reserved Last updated Normally, raised letters or numbers in protective depressed pads are easiest to manufacture. This will get the wax melting out the bottom before it begins to expand. Logos can be investment cast to almost any design.
Much more than documents.
The Egyptians and Chinese lettering investment casting the process in their early invesment to make statues and jewelry. The investment casting method was largely ignored as an industrial process for the fabrication of parts until the demand for rapidly investmennt parts during World War II created the need for near net-shape components that could readily be put into their final form. Then new inorganic high temperature ceramic mold binders were developed to industrialize the process applications to include high strength and corrosion resistant materials such as low to high carbon alloy steel, tool steel, lettering investment casting steel, and nickel and cobalt base alloys. Aluminum and brass alloys are available. It is a process capable of producing intricate shapes weighing from a small fraction of an ounce up to forty pounds or. A injection molded wax pattern is used for each part produced which is then encased in multiple layers of ceramic material.
Investment Cast Tooling
Investment casting is an industrial process based on lost-wax casting , one of the oldest known metal-forming techniques. Investment casting has been used in various forms for the last 5, years. In its earliest forms, beeswax was used to form patterns necessary for the casting process. Today, more advanced waxes, refractory materials and specialist alloys are typically used for making patterns. Investment casting is valued for its ability to produce components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. The fragile wax patterns must withstand forces encountered during the mold making. Much of the wax used in investment casting can be reclaimed and reused.
Pennsylvania Precision Cast Part’s Investment Casting Process

One of the primary benefits provided by the Investment Casting process is invsetment part czsting can very often be furnished at negligible additional cost. Wall Thickness for Investment Castiny Minimum fasting thickness and corner radii depend upon part configuration and size. Applied-marking such as that made by laser, vibro-etch or ink stamping is applied to the finished product and used lettering investment casting often to identify castings with ltetering that changes part-to-part or lot-to-lot such as serial numbers or heat treat lot data. Contact our team today to get your investment cast parts in half the time. The more pieces that can run on a mold, the lower the part cost. The reason for this preference is that positive features on a part are the inverse in the pattern mold. If you are really concerned [about lettering quality], then I would suggest using a much stronger investment Using the mix [water:investment ratio] gave the best result for all models, and we always kept the sprues away from lettering. Small investment castings may have walls cast to. Request a Quote. Reverse the draft if in relief. If a design contains features that will raise scrap or rework rates and piece pricethe Signicast Estimating Engineer will recommend design modifications to keep the piece price. Going deeper makes the thin areas of the lettering wider and more likely to investmeent out, [otherwise] the thin spots in the lettering will fail, as they are too close to the surface. We will devote our attention here to integral-marking. Part size and weight are the most critical factors in determining part cost because mold capacity is limited by both size and weight.
