SHENGFA Hardware is well-known in the industry for producing high-quality screw machine parts using nylon via its nylon CNC machining Service. Our company is located in Ningbo, China, established in 2007 and has a history of more than 17 years so far.

Nylon is a versatile, low-cost plastic ideal for producing parts that require high compressive strength and friction resistance, while being machined to very tight tolerances. It can be used in place of metal in some scenarios, allowing for longer wear parts that require less maintenance than their metal counterparts. Nylon is generally stronger than PTFE, PEEK, and UHMW, can withstand higher temperatures, and is more cost-effective. Ningbo SHENGFA Hardware Factory focuses on nylon CNC machining service and has been leading this field for many years. With many years of experience in plastic processing, especially nylon processing, we have been involved in various projects requiring high precision, precision and quality. We consistently produce nylon machined parts that meet or exceed our customers' expectations.
