Side Viewing Interferometric Probe Alignment for near Vertical Steel Sidewalls
Aligning side-viewing optical probes on vertical steel sidewalls requires tip-tilt control within 0.05 degrees to preserve coherence fringe visibility.
Stavax Tool Steel
Meaning
Premium stainless tool steel alloy optimized for plastic injection molds features high corrosion resistance and high polishability. In medical and optical molding shops, stavax tool steel is the standard material for cavities and cores that handle corrosive or highly abrasive resins. This material selection guarantees that the mold retains its high-gloss finish and dimensional accuracy over millions of production cycles.
Tooling Durability
Molders choose this specific alloy to withstand the aggressive chemical by-products released by some polymer grades during processing. When molding fluoropolymers or polyvinyl chloride, corrosive gases can attack the mold surface, causing pitting and surface decay that ruins the molded part finish. Utilizing stavax tool steel prevents this corrosion and reduces the frequency of mold cleaning cycles.
Surface Capability
Achieving a mirror finish is necessary for producing optical lenses or high-clarity medical syringes. This steel grade contains a uniform distribution of carbides, which allows it to be polished to an extremely low surface roughness without creating pits or orange peel defects. The resulting smooth finish minimizes polymer adhesion and the force needed to eject the part from the cavity.
Maintenance Optimization
Long-term storage of molds is simplified because the steel resists rust without heavy greasing. This characteristic ensures the tool can be returned to service quickly.
