Shenzhen, Guangdong: China Surgical Needle, Inc.(China Surgical Needle), a Guangdong medical manufacturer and pioneer in precision bending, 3D bending, and medical laser tube cutting, utilizes automated manufacturing cells that were designed by our in-house engineering team. Each manufacturing cell is capable of machining its own specific range of tube diameters and lengths. Typical core tube materials include ABS, Polysulfone, Noryl, PVC, CPVC and stainless steel. These cells are very efficient and generate cost effective products. Individual cell capacity can be as high as 650,000 pieces annually.
Much more than just a medical manufacturer, we have been machining “Core Tubes” for the liquid filtration and the reverse osmosis (RO) industries for over 30 years. Core tubes are designed by our customers for use in a variety of industries and applications including; water purification, petroleum grading, removing alcohol from beverages, separating water from fruit juices, desalination, etc. Working with many of the Liquid Filtration and RO OEM’s from infancy, we continue to provide engineering expertise as well as products built to each customer’s specifications.
The tube cell capabilities include machining both ends of the tubes. Features that can be generated include: turned and/or bored diameters, chamfers, grooves, multiple rows of drilled cross-holes, abraded surfaces, slots and specific overall lengths. Outside diameters range from 0.5 up to 4 inches. Overall lengths are typically held to +/-0.030″, but can be held tighter if the application requires it. Tighter tolerances require temperature controlled inspections because the overall length can vary significantly at different temperatures. For example, a 40″ long ABS tube will grow 0.002″ per degree of temperature increase. Size, location and geometry of other machined features are held to standard CNC controlled tolerances.
The efficiency of the cells is created by automation specific to the product. Robots and multiple work centers are used with little operator intervention. The key to the cells is the crosshole drilling work center. Our cells can generate multiple holes simultaneously. A typical core tube may require 160 holes per tube.We have designed tooling, fixturing, and processes that can drill all required cross holes in a few seconds. Our experience allows us to design drills specific to an application that will generate thousands of burr free holes without drill wear.
