Cleaning & Chemical Processing Capabilities

Aqueous Cleaning Passivation

Our Nadcap-accredited chemical processing line has capabilities for stainless steel, Inconel, aluminum, and titanium alloys. Capabilities exist for alkaline clean, metal joining clean, acid clean, clean and etch, and passivation.

Precision Cleaning

R100 Cleanroom Certified to ISO 6

We have ISO 14644 Certified Clean Rooms and ISO Class 6, ISO Class 8, AS598 and IEST-STD-CC1246-capable facilities. Equipment exists to precision clean, contamination check, and package per industry standards to maintain required cleanliness levels. Both flexible and rigid parts can be processed.

HF Cleaning

To ensure the quality of finished product, a special cleaning system has been developed to secure the integrity of the final product. This is performed by removing a very thin (.002 inch) layer of contaminants on completed titanium assemblies. Strict testing and monitoring of the cleaning process take place before, during and after the process.

Vapor De-Greasing

We use a Controlled Vapor Degreaser, an in-process cleaning station that utilizes a blend of non-ozone-depleting fluorinated solvents that meet or exceed our customers’ cleaning requirements. Applications include:

• Caustic spray and caustic flush to meet CJ 4.1 standard
• Precision cleaning with an IPA flush and agitation

Nickel Plating

STS Aerospace has developed a nickel-plating process to ensure good bonding on gold-brazed joints on products. This process puts an extremely thin but uniform layer of nickel plating on parts. Quality is assured by continuously monitoring with a variety of modern instruments.

Dry Film Lubricant

This important lubricant is required on many STS Aerospace products and is applied in a controlled environment, then cured in a calibrated and computer-controlled drying oven. Each run is carefully monitored, documented, and tested prior to release.
