21 CFR Part 820 is a set of FDA regulations that govern medical device quality systems. Detailed within are current good manufacturing practice (cGMP) requirements ensuring medical devices distributed within the United States are effective, safe, and compliant. The regulations apply to any facility

Sand casting is a metal forming process in which a sand mold is first created. Molten metal is poured into the mold cavity for solidification. The sand shell is subsequently removed after the metal components have cooled and formed. Some sand casting components require a secondary machining

One of the reasons for choosing investment casting over other casting processes is its superior surface finish. This blog post will look at what it is about the process that results in these finishes, the finishes achievable, and the benefits of a better finish. Mirroring the Surface The in

Sand casting is a metal forming process in which a mold is formed from a 3-dimensional pattern of sand. Molten metal is poured into the mold cavity, and the sand shell is removed after the metal components have cooled and hardened. Some secondary machining processes may be required after ca

Whether the input form of the material is bar stock, a forging or casting, precision machining process is employed to produce accurate components with tight tolerances and excellent surface quality. Material is removed from the workpiece during machining to achieve the desired end results.

The investment casting process enables the production of intricate shapes which maintain high dimensional accuracy and high surface quality. Stainless steel is often chosen for the material because of its strength and exceptional corrosion-resistant properties. This benefits combination mak

After the primary manufacturing and cooling processes, comprehensive heat treatment of aluminum castings can ensure they are capable of meeting the end user’s exact specifications. This controlled process alters the castings’ physical properties to increase hardness or tensile strength, and

Sand casting is often thought of as a process for small to medium quantities, but with one modification it’s an economical process for large quantity production. That modification is to part the mold vertically rather than horizontally. Understanding why this makes a difference, and how you

Foundry experts will tell you alloy steels are more challenging to cast than carbon steels, but this shouldn’t influence your choice of metal. In fact, investment casting alloy steel yields bigger benefits than using the same process for carbon steel. If this seems like a contradiction, the

The precision machining process uses a diverse array of tools to precisely remove unneeded material and achieve the most complex design criteria for a piece. These processes are used to provide critical components in diverse industries including medical, aerospace, industrial, energy, and h

Many sophisticated workpieces require the use of precision machining after the casting process to achieve the final, desired qualities. Advanced, computerized machine tools are used in precision machining to satisfy the demanding tolerances, and create the most complex shapes required for s

  Speed is essential when developing new products. The faster you get your parts into the customers’ hands the better your chances of winning their business. This puts the project focus on tooling lead time. Sand casting patterns and core boxes don’t take as long to produce as metal ca

Computer numerical control (CNC) offers the capability of controlling the various machining processes in a precise manner, leading to the potential for cost savings in the overall production process. CNC machining is generally worth the investment because the processes render precise result

In addition to the primary manufacturing process technologies, comprehensive heat treatment of precision machined parts can ensure products are capable of meeting the end user’s exact specifications. This controlled process of heating and cooling the parts to alter their physical properties

If you need parts to withstand high temperatures, oxidation and corrosive chemicals, consider investment casting them in Inconel. Inconel is a nickel-based superalloy that resists oxidation and retains its strength at temperatures over 1,000° F. It’s produced in a number of different compos

The automotive industry looks for high quality and low prices. Sand casting helps them have both. It’s a process that scales well, making it cost-effective for low to high volumes. It works with a wide range of metals and is capable of high finished part quality. However, it’s not appropria

Sand casting is a metal forming process in which a mold is first formed from a three-dimensional pattern of sand, and molten metal is poured into the mold cavity for solidification. The sand shell is subsequently removed after the metal components cooled and formed. Some components require

Though light and strong, titanium is difficult to machine, weld, and form. That makes investment casting the best way of producing parts in this metal. In this blog post we’ll explain: Why titanium is often the preferred material for parts for demanding environments What sets it apart from

Precision machining involves using grinding, cutting, turning, milling, sawing, and boring tools to remove specific amounts of material from a workpiece until the desired end result is achieved. This article looks at the types of grinding machines used in the precision machining business. W

Sand casting is the metal-forming process of first creating a mold from a three-dimensional pattern of sand. Molten metal is then poured into the mold cavity for solidification, after which the sand mold is removed. But, there are several variations that may make the process take longer. A
