The ROBOWORKER filling shoes for powder presses ensure optimal powder flow, extending from the powder silo to the cavity. This significantly contributes to highest part quality and process stability.
In the production of our high-quality filling shoes, we leverage state-of-the-art manufacturing technologies. By combining 3D-printed plastic elements with CNC-manufactured components, we create lightweight, precise, and robust filling systems. This optimized design allows for even filling of the cavities and ensures excellent density distribution. As a result, consistently high product quality is achieved, meeting even the strictest requirements.
Discover our comprehensive family of filling shoes, which precisely fill both single and multiple cavities. In our range, you will also find variants with mini hoppers, ideal for small batches and test parts, as well as flexible accessory kits that provide you with additional options
Our filling shoes can be perfectly integrated into our ROBOWORKER powder presses RP and nearly all powder presses.

Our filling shoe technology combines innovative details, including an optimized structure, lightweight materials, and flexible adjustment options that allow for precise customization of filling parameters. Additionally, the filling shoes are wear-free, as they are equipped with interchangeable high-performance seals, among other features. These characteristics not only enhance the efficiency of your production but also ensure exceptional performance.
Gain production advantages and improve part quality with ROBOWORKER's unique filling shoe technology.
The ROBOWORKER filling shoes can be perfectly integrated into nearly all powder presses. To ensure an optimal fit, the filling shoes are available in various designs:
The standard variants listed above are tailored to the volume to be filled and the pressing forces. Custom adjustments to the standard filling shoes are available upon request for a one-time design fee.
The mini hopper is a compact powder funnel that can be either mounted on the filling shoe or permanently integrated with it, providing direct powder feed without detours. In contrast to conventional powder supply via hoses, the mini hopper offers direct and efficient filling. This makes it ideal for smaller batches and test parts. Thanks to its easy accessibility and refillability, it ensures uncomplicated handling and maximum flexibility in the production process.
Our adapter kits allow you to flexibly adjust the hose diameter to optimally connect the powder silo of your press with the filling shoe. Each kit includes an adapter for a larger nominal width, the corresponding larger hose, and various reducers. These components ensure precise alignment of the hose’s inner diameter with the flange of the customer’s powder silo.
To connect an existing customer-specific filling shoe fork, we also offer an adapter kit. This kit allows both the diameter and width of the fork mount on the filling shoe to be adjusted flexibly. It includes adapters for various mount diameters as well as an alternative shaft for individual adjustment of the fork width.

A filling shoe is a component used for distributing powder within a powder press. It is responsible for filling materials such as tungsten carbide or ceramic powder into the die to produce a compact (green part). The filling shoe moves horizontally over the die plate, guiding the powder into the cavity. Powder is fed into the filling shoe via a hose connected to the powder silo (storage).
ROBOWORKER’s filling shoes for powder presses are designed to ensure optimal powder flow, uniform filling of the cavity, and flexible adjustments to fine-tune filling parameters. This results in excellent density distribution and high-quality compacts.
