Wax Additives for High-Precision Sintered Components

High-precision sintered components require consistent powder flow, minimal friction, and residue-free sintering to meet tight tolerances. Wax additives help achieve these goals by improving lubrication and surface finish.

Benefits of Wax Additives

• Flow Improvement: Promotes uniform powder filling and compaction.

• Friction Reduction: Reduces wear on tooling and improves ejection of compacted parts.

• Residue-Free Sintering: Wax decomposes cleanly, avoiding carbon contamination.

Technical Application

Oxidized polyethylene or paraffin waxes are preferred for their stability and clean burnout. The optimal usage is determined after technical evaluation according to specific alloy compositions and process conditions.

A precision gear manufacturer incorporated a wax additive into their powder mix and achieved more uniform compaction, smoother surfaces, and reduced rework after sintering.
