TOOLING DESIGN

Tooling design is the foundation of successful powder metal manufacturing. Proform’s experienced engineers design precision tooling that optimizes part quality, dimensional accuracy, manufacturability, and long-term production efficiency.

PART MOLDING

Powder metal molding transforms precisely blended metal powders into near-net-shape components using high-pressure compaction. This process delivers exceptional dimensional accuracy, material consistency, and production efficiency while minimizing waste.

SINTERING

Sintering is the controlled heating process that bonds compacted metal particles into a strong, durable component. Carefully controlled temperatures and atmospheres optimize mechanical properties, dimensional stability, and overall part performance.

SIZING

Secondary machining provides the precision required for critical features, including tight tolerances, threads, holes, and complex geometries. By combining powder metallurgy with precision machining, Proform delivers components that meet exact requirements.

OIL IMPREGNATION

Oil impregnation fills the interconnected pores of powder metal components with lubricant, creating self-lubricating parts that reduce friction, minimize wear, and extend service life. The process is ideal for pats requiring reliable, maintenance-free performance.

QUALITY CONTROL

Quality control is integrated throughout every stage of the manufacturing process to ensure consistent performance and precision. From raw material verification to dimensional inspection and final validation, every component is held to rigorous quality standards before shipment.
