casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods.
Hot forging is our process of choice when it comes to small simple parts in high volume. Its simplicity, reliability, and long life of the components produced, plus the little waste during the production makes it highly affordable.
Turning was one of the first processes we ever used because it is the main process to produce fasteners. Due to the high tolerances and surface finishes that turning can offer, it is ideal for adding precision rotational features to a part whose basic shape has already been formed.This process can also be used to refine features on parts that were manufactured using a different process.
Milling is versatile for a basic machining process, but because the milling set up has so many degrees of freedom we use it when we need to manufacture complicated components that are not axially symmetric and have many features, such as holes, slots, pockets, and even three dimensional surface contours.

Computer Numerical Control (CNC) manufacturing is one of the most reliable manufacturing processes. That is why at Polaris we use it to manufacture precision parts. Previously a rather expensive and complicated process, CNC manufacturing was not so common, but with time it has become a norm in precision manufacturing. At Polaris International we count with the highest equipment to ensure the highest quality in our products.
Thread rolling is one of the first and most important processes we use to create top end fasteners. By thread rolling the raw material, it becomes much stronger and smooth, besides it has an amazing accuracy that meets the highest quality standards of our clients.
