A While there have been many issues involving the environment, safety, and health, the inherent lubricity characteristic of this plating material has never been completely duplicated over a full range of applications. For instance, in salt water, a cadmium coating forms a protective cadmium chloride surface layer which is not sacrificial.

A To ensure thread assemble ability of mating fasteners, the specified thread fit allowance in the inch series, divided by 6, provides the maximum coating thickness.

A Usually coatings and platings are less expensive than employing an upgrade from a basic carbon steel to a premium material such as stainless steel. Coatings or platings may help to improve appearance, control torque tension, minimize thread seizure, and may serve as product identifiers.

Dies are classified as: single cavity, multiple cavity, combination and unit dies.

A single cavity die requires no explanation. Multiple cavity dies have several cavities which are all identical. If a die has cavities of different shapes, it’s called a combination or family die. A combination die is used to produce several parts for an assembly. For simple parts, unit dies might be used to effect tooling and production economies. Several parts for an assembly, or for different customers, might be cast at the same time with unit dies. One or more unit dies are assembled in a common holder and connected by runners to a common opening or sprue hole. This permits simultaneous filling of all cavities.

A The complete cycle of the die casting process is by far the fastest known for producing precise non-ferrous metal parts. This is in marked contrast to sand casting which requires a new sand mold for each casting. While the permanent mold process uses iron or steel molds instead of sand, it is considerably slower, and not as precise as die casting.

A Die casting is a manufacturing process for producing accurately dimensioned, sharply defined, smooth or textured-surface metal parts. It is accomplished by forcing molten metal under high pressure into reusable metal dies. 

A Sand and investment casting have similar processes, but sand casting cannot always make small, intricate parts. Sand casting also often utilizes heavier weight limits, sometimes greater than a ton.

A  In general, tempering temperatures are inversely related to strength and hardness and directly related to ductility and toughness.

A  Non-heat treatable grades of steel are those which cannot have their mechanical properties modified due to heat treating. They achieve their mechanical properties through a combination of chemistry selection and forging method.

A Forging reduction should be sufficient to consolidate the defects inherent to the casting process such as porosity and other voids while achieving a general wrought structure by breaking down the cast structure. A 3-to-1 reduction, using the open die process, is usually sufficient to achieve these results (with strict control of the process, less than 3-to-1 can be sufficient). Depending on the alloy and customer requirements, higher reduction may be necessary to achieve certain additional mechanical or physical requirements.

A A forging is metal that has been heated in order to soften it then pressed, hammered, or otherwise formed into a shape. All forgings begin as cast starting stock. Forgings benefit from the forming operation which enhances their overall toughness and fatigue resistance.

A Any metal that contains iron is considered ferrous. You can quickly identify ferrous metal by checking it with a simple magnet. If the magnet is attracted to your material it is ferrous.

The investment casting process offers many unique benefits over not only other casting processes, but also over many other common manufacturing processes, such as machining, welding, forging, stamping, and assemblies.  Examples of these benefits are :

• Design Freedom: The investment casting process allows the designer the flexibility of nearly  infinite alloy choices, and great flexibility in external and internal configurations.
• Unlike other casting methods, there are no draft requirements in the investment casting process, allowing for much more accurate dimensional conformance.
• Reduced Machining: Investment castings are produced to close tolerances and near-net size. There is little secondary machining required, thus offering savings in machining time and material costs.
• Mechanical Properties:  Investment castings will usually be able to meet the same mechanical properties of components manufactured from wrought metals.
• Superior Aesthetics:  The surface finish of investment castings is consistently better than 125 RMS.  Fine details, text, logo’s and design features not attainable with other processes are possible.
• Reproducibility: The investment casting process produces a reliable and consistent product.

A When you consider any process consider the total finished cost of the item. Be it forging, fabrication, machined or casting, it is your total cost that is often the key driver in your decision. Value added features such as consistent near net shape castings, superior as cast surface finish and appearance, cast part numbers, logos and other important branding considerations and are enhancements not easily included with other processes. Many parts that require miscellaneous machining operations or fabrication can be investment cast to full customer satisfaction. Often our parts become an integral part of a fabrication or machined assembly. Again, it is important for our customers to meet us and discuss your requirements to realize the potential value and savings.
