Here at J H Engineering, we meticulously manufacture Screw Ring Plungers, Barrel Heads, and Nozzles using Nitro Alloy, toughened to the hardness of 30/32 RC in ‘S’ or ‘T’ condition. With durability and unmatched performance as our core pillars, we aim to be instrumental in transforming your experience with every product we manufacture.
Our unique machining process ensures that both the inner (0.5 mm) and outer (1 mm) layers of each product achieve exceptional precision. Controlled stress development refines the bottom hardness, boosting resilience under demanding operating conditions.
After stress relieving, every dimension is ground to precise tolerances, ensuring a seamless fit and extended service life. Through a specialized gas nitriding process, we achieve a surface hardness of 64/66 RC with a case depth of 0.5/0.6 mm. This process delivers unparalleled strength and durability in every application.
