SURFACE ENGINEERING
What is Industrial Degreasing & The Science of Surface Purity
Industrial degreasing is a critical surface preparation process designed to meticulously eradicate machining oils, stamping lubricants, and particulate contaminants from metal and plastic substrates. Unlike standard washing, advanced degreasing utilizes engineered aqueous solutions or specialized solvents combined with powerful mechanical agitation to penetrate complex part geometries. This absolute contaminant removal is mandatory to prevent adhesion failures and surface defects in subsequent electroplating, coating, or precision assembly stages. By achieving optimal surface energy and pristine cleanliness, our degreasing protocols provide the essential foundation for high-performance components utilized in demanding medical device, robotics, and automation applications.
Initial Soak & Gross Soil Emulsification
Raw stamped or machined components undergo an initial bulk cleaning phase utilizing highly regulated alkaline baths or specialized industrial solvents. This primary immersion process aggressively breaks down, lifts, and emulsifies thick stamping lubricants, forming oils, and heavy machining coolants, preparing the substrate for subsequent precision cleaning stages without causing dimensional degradation.
Ultrasonic Precision Cleaning
The prepared parts are submerged in highly controlled tanks and subjected to intense, high-frequency ultrasonic waves. This technology generates microscopic cavitation bubbles that forcefully implode upon contact with the substrate. This deep-cleaning action effectively blasts away deeply trapped microscopic residues, grinding dust, and cutting fluids from intricate part geometries, internal cavities, and blind threads.
Deionized Rinsing & Spot-Free Drying
To completely eliminate residual cleaning agents and prevent flash oxidation, components are sequentially processed through multiple cascading deionized (DI) water rinses. This meticulous rinsing is immediately followed by rapid, forced-air thermal baking or vacuum centrifugal drying. This critical step guarantees a completely spotless, moisture-free surface ready for immediate secondary finishing or packaging.
Surface Purity Validation
Cleanliness is strictly verified before any batch leaves the degreasing line. Utilizing rigorous outbound inspection protocols, including standardized water break tests, dyne pen surface energy testing, and visual under-magnification checks, our quality assurance team guarantees every component meets strict zero-residue specifications and aligns with global environmental and engineering compliance standards.
Surface engineering isn’t just a finishing touch—it’s a critical performance factor. You don't just need a vendor; you need a partner who masters the technical nuances of both metal and plastic. Discover our tailored solutions designed to meet your industry's most rigorous standards.

ALLOY VERSATILITY
Compatible Substrates & Material-Specific Degreasing Protocols
Effective industrial degreasing is not a universal application; the chemical compatibility and surface reactivity of the substrate strictly dictate the precise cleaning methodology. Kravzik engineers meticulously select custom aqueous formulations, specialized solvents, and specific ultrasonic frequencies tailored to the unique metallurgical and chemical properties of your components. This targeted approach guarantees absolute contaminant removal without inducing surface etching, flash oxidation, or material degradation across a diverse range of critical alloys and engineered plastics used in robotics, automation, and medical devices.
Austenitic Stainless Steel (304, 316L) & Titanium (Ti-6Al-4V)
Heavily utilized in surgical instruments and cleanroom automation equipment. These critical alloys require the complete extraction of heavy machining coolants and polishing compounds without compromising the surface structure. We utilize specialized high-temperature, non-silicated aqueous cleaning agents combined with rigorous multi-stage deionized (DI) rinsing to guarantee zero chemical residue, ensuring the substrate is perfectly prepped for subsequent passivation, electropolishing, or sterile packaging.
Aluminum Alloys (6061-T6, 7075)
Essential for lightweight robotic arms and automated actuator housings. Aluminum is highly susceptible to galvanic corrosion and destructive surface pitting when exposed to standard highly alkaline industrial cleaners. Kravzik deploys strictly regulated, silicate-inhibited aqueous solutions and pH-neutral solvents. This highly calibrated chemistry precisely dissolves heavy stamping lubricants while preserving the delicate natural oxide layer and maintaining aerospace-grade dimensional tolerances.
High-Carbon & Alloy Steels (A2, D2, 1095)
Frequently specified for high-wear metal stamping die components and heavy-duty robotic structural linkages. The primary critical risk during the degreasing of high-carbon substrates is instant flash oxidation (rusting) immediately after protective oil removal. Our automated processing lines seamlessly integrate an immediate rust-inhibiting flush or transition the ultraclean parts directly into subsequent controlled coating or oiling lines, completely eliminating flash rust risks.
Conductive Copper & Brass (C11000, C36000)
Critical for highly conductive electronic contacts and automation sensor housings. These specific non-ferrous alloys are highly prone to tarnishing, etching, and discoloration from reactive cleaning agents or residual moisture. We process these components using specialized, sulfur-free solvent systems and mild alkaline baths infused with specialized tarnish inhibitors, followed immediately by rapid centrifugal vacuum drying to maintain pristine electrical conductivity.
Engineered Thermoplastics (PEEK, POM, Polycarbonate)
Produced frequently in our precision injection molding division for specialized medical enclosures and robotic insulators. Aggressive industrial solvents can easily induce environmental stress cracking (ESC) or surface softening in polymers. We process these delicate materials using low-temperature, mild aqueous surfactants paired with gentle 28kHz ultrasonic agitation to safely lift mold release agents and handling oils without compromising the molecular structure or aesthetic finish.

PROCESS GUIDELINES
Essential Design Guidelines & Process Limitations for Degreasing
Proactive design optimization ensures your components achieve laboratory-grade surface energy and absolute purity without production delays. Consider these geometric, structural, and material factors before finalizing your CAD models to ensure maximum contaminant extraction during our precision degreasing and ultrasonic cleaning cycles.
Components must be designed with adequate drainage pathways to prevent “chemical carryover” between cleaning stages. Tightly overlapping joints, non-seal-welded seams, and deep blind pockets can trap processing fluids. This trapped chemistry can eventually seep out—known as “bleed out”—interfering with subsequent medical-grade coatings or causing localized corrosion during storage.
While ultrasonic cavitation is highly effective, it requires direct fluid-to-surface contact. Air pockets trapped in deep blind holes or ultra-narrow internal channels prevent the cleaning solution from reaching the contaminants. For critical internal cleanliness, we recommend incorporating auxiliary vent holes or maintaining a diameter-to-depth ratio that allows for complete air displacement and fluid exchange.
Industrial degreasing at Kravzik is a 100% non-abrasive process with 0.00mm material removal. Unlike etching or plating, it does not alter the substrate’s engineered dimensions. However, engineers must account for the fact that “as-machined” measurements include the thickness of lubricant films; once these are removed, the “true” metal-to-metal fit will be revealed, which is critical for high-precision robotic assemblies.
Certain high-performance solvents can induce environmental stress cracking (ESC) in specific polymers or damage delicate rubber seals and gaskets. If your component is an assembly of different materials (e.g., metal with plastic inserts), our engineering team must be notified of the exact material grades to calibrate a “Safe-Substrate” aqueous cleaning profile that removes oils without degrading the assembly’s structural integrity.
Removing protective manufacturing oils from high-carbon steel and cast iron leaves the surface highly “active” and vulnerable to instant flash oxidation (rusting). For parts not immediately moving to a secondary coating line, we recommend designing in a requirement for a temporary water-soluble rust inhibitor or VCI (Vapor Corrosion Inhibitor) packaging to maintain the pristine, degreased surface.
