Powder metallurgy is an advantageous process that produces a wide variety of high quality, precision alloy parts. We use this process to provide our clients with cost-effective parts produced at, or near, final dimensions. By tapping into the diverse capabilities of powdered metal, we can innovate with new concepts and help our clients achieve their unique objectives.

At Allied Sinterings, we only use top-quality powdered metal and materials. The design flexibility of powdered metal allows us to develop parts with enhanced strength, durability, heat resistance, and more. We have worked with some of the most intricate and complex geometries and are highly respected in the automotive, medical, telecom, and industrial equipment sectors. A recent success involved helping a client achieve tight inner diameter specifications for electric vehicle (EV) parts.

The Problem: Realizing a Pinion Gear Design with Extremely Tight Tolerances

One of our automotive clients had unusually tight tolerance requirements for an inner diameter (ID). The requirements were tighter than the typical ± 5/10ths diameter found in small powdered metal components. Specifically, the client needed a tight ID for a pinion gear part used in the motor shaft of their electric vehicles. The part needed to be small enough to fit onto the shaft.

The Solution: Achieving 7/10ths of a Typical Tolerance for an ID

We manufacture precision parts to some of the tightest tolerances using a combination of tight tool maintenance and process control measures. After confirming the client’s performance requirements, we selected the necessary materials and began the powder metallurgy process. We were able to fabricate the required component without needing to resize (ream, drill, or ballize) the part. We were able to hold a ± 3.5/10ths on a press fit ID for a total of 7/10ths tolerance.

The result was another satisfied customer who benefitted from a precision component of the highest quality, which we were happy to manufacture.
