RPI has a wealth of experience machining hard nickel alloys (e.g., Inconel, titanium, Hastelloy, stainless, and aluminum). We also offer plastic machining services, commonly working with Vespel, Delrin, PEEK, acrylic, Rulon, phenolic, Vesconite, and others.
We are experienced in determining the appropriate tooling, speeds, feeds, and machining strategies to meet a wide range of finishes while maximizing efficiency and quality.
CO2 and fiber lasers precisely mark most plastics and metals without ink or tool marks.
C02 and fiber lasers engrave metal without ever touching the part’s surface. Laser engraving is well-suited for materials such as stainless steels, tool steels, hardened steel, titanium, carbide, aluminum, brass, and carbon graphite.
Equipped with rotary heads, laser rotary engraving machines precisely and efficiently engrave cylindrical parts made from most metals and plastics.
When your parts require plating, anodizing, heat treating, powder coating, and other finishing processes, we arrange these key services with one of our tested and trusted vendor partners. We thoroughly inspect all parts to ensure they meet our exceptionally high standards for quality and consistency.
RPI is committed to the continuous care of your parts, beginning with the receipt of your material and extending through to machining, inspection, and secure packaging and handling.
