Degreasing powder AR-815 is a strong alkaline industrial cleaning agent specially designed for metal drill bits and precision parts, and its application spans multiple core industries of metal processing and manufacturing. In the tool manufacturing industry, this product is an indispensable degreasing cleaner on the production line of high-speed steel drill bits, carbide drill bits, and tungsten steel drill bits, efficiently removing cutting oil, anti-rust grease, polishing paste, and carbon deposits from the spiral flutes and cutting edges. In the precision machining industry, the degreasing pretreatment of tools such as taps, milling cutters, and reamers before coating or heat treatment also relies on the deep degreasing capability of AR-815 to ensure the adhesion and processing quality of subsequent processes.
In the automotive parts manufacturing industry, AR-815 is widely used for surface degreasing processes of metal parts such as engine components, transmission gears, and brake system parts before electroplating, spraying, or heat treatment, meeting the stringent cleanliness standards of the automotive industry for parts. In the bearing industry, this product is used for cleaning various rolling bearings and sliding bearings before assembly, quickly removing anti-rust oil and processing grease, ensuring assembly precision and operational reliability. Additionally, in the general metal surface treatment industry, for degreasing processes before surface treatments involving painting, electroplating, phosphating, blackening, etc., AR-815 can serve as the core agent of an efficient alkaline cleaning solution.
From a process adaptability perspective, AR-815 supports three mainstream industrial cleaning methods: spray cleaning, ultrasonic cleaning, and immersion cleaning. The spray process is suitable for high-volume assembly line operations; ultrasonic cleaning has unique advantages for degreasing deep holes and narrow slits of precision tools; the immersion process is often used for batch processing of small workpieces. Its triple decontamination mechanism of saponification, emulsification, and chelating dispersion can simultaneously address various processing residues such as mineral-based cutting oils, synthetic ester anti-rust oils, and solid polishing waxes, achieving a broad-spectrum degreasing effect of "one agent for multiple uses."

Tool Manufacturing Industry: It is recommended to use ultrasonic cleaning process before drill bit tempering or coating, with a concentration of 3%–8% AR-815 aqueous solution, temperature controlled at 50–70°C, cleaning time 5–15 minutes, to thoroughly remove carbon deposits and heavy oil stains in the spiral flutes. For carbide and tungsten steel drill bits, due to material characteristics, it is recommended to appropriately reduce temperature and control immersion time to avoid prolonged contact.
Automotive Parts Processing: A spray cleaning line is recommended, with concentration 3%–6%, temperature 60–80°C, spray pressure 0.2–0.5 MPa. The treated workpieces must be thoroughly rinsed with clean water and quickly dried to prevent alkaline residues from affecting subsequent electroplating or spraying quality. For precision fit parts, it is recommended to use ultrasonic process for secondary fine cleaning.
Bearing and Precision Parts: A multi-tank ultrasonic cleaning line should be used, with the initial cleaning tank concentration of 5%–8%, and after fine cleaning, rinse with deionized water. Pay attention to the placement of workpieces to facilitate solution circulation, avoiding overlapping that leads to cleaning dead spots.
