常州良旭是高新技术企业，现有发明专利、实用新型专利、外观设计专利30多项、独家技术20多种，以一流的弯管技术得到了国内外知名企业的认可。
为确保产品质量，公司从“原料采购”到“产品发交”道道把关，原材料进场用光谱仪、拉力试验机做化学成分分析及物理性能试验，剔除不合格材料；生产过程用关节臂测量仪保证合理公差范围，气密性检测仪检测焊接质量和管端连接结构的气密性、影像测量仪来分析特殊特性质量问题；管件表面加工后，抽检部分产品进行盐雾试验，确保外观质量。
全过程的质量控制，使各类产品无论是外观品质，还是性能质量都能得到保证，在汽车行业一直遥遥领先，连续五年被中国重汽评为合格供应商并取得独家供货权力。
公司拥有国际最先进的全自动数控弯管设备，弯曲半径最小为0.8D，与通常弯曲半径为1.5D相比，给整车安装保留了更多的空间，避免了干扰点；减薄率≤20%，如2mm厚的管子弯曲后还＞1.6mm；采用伺服电机控制，与以往的液压系统控制相比，控制更为精密，自动化程度更高，所有的调试、润滑等工作都由电脑控制完成，提高工人安全性，并可远程控制。
“切管”采用机器人三维激光切割机——与传统金属圆锯机或等离子切割相比，操作简便，切割加工时只需设定好产品的加工参数，即能精准操作。激光切割切口精细，切缝垂直度能有效保证，切割误差为0.01mm。
管端”采用管端成型机进行成型——生产时由电脑设定参数，一次性起箍成型，与国内焊接一体式或法兰连接式相比，工艺简单、外观光滑、连接方便、两端角度一致，气密性达到100%，安装角度可以调整，整车安装时更便捷。
所有管件、法兰全部采用Panasonic机器人焊接，完全保证了焊接的外观和质量，产品外表面加工均为流水线式生产。
公司从国外引进金属软管的生产设备，采用进口的原材料进行加工，保证了产品的高柔性、气密性、抗机械冲击等等性能，延长了使用寿命，使其达到国际水平。公司发展前景一遍光明。相信在不久的将来我们会做得更大，走得更远。
Changzhou Liangxu Auto Parts Co., Ltd. is located at Changzhou, a famous historical city south of Yangtze River, which is equidistant from Shanghai and Nanjing. Located at Changzhou National Hi-tech Development Zone, our company has enjoyed favorable geographical location and convenient transportation. The distance from our company to Changzhou Airport, Changzhou Port and Shanghai-Nanjing Expressway is within 15km.
Our company covers an area of over 40mu, and our plant covers an area of over 30,000m2. We have been engaged in research, development and manufacturing of pipe bending equipment since 1995. We have focused on processing and production of radiator outlet pipes and other pipe products since 2000, and have become a main supplier of pipe products to China National Heavy Duty Truck Group Co., Ltd. since the beginning of 2006. At present main products of our company include over 400 exclusively supplied products, such as exhaust pipes of HOWO series, A7 series, T7 series, C7 series, etc., intercooler inlet and outlet pipes, radiator outlet pipes, fender supports, clamps, etc.
As a hi-tech enterprise, Changzhou Liangxu has more than 30 patents for invention, patents for utility models and design patents and over 20 exclusive techniques. Our first-class pipe bending technology has been approved by renowned enterprises at home and abroad.
In order to guarantee product quality, our company closely checks each procedure from purchase of raw material to product delivery. All of the coming material receives chemical component analysis and physical performance test by spectrograph and tension tester, and defective material is rejected; hinged arm measuring instrument is applied during production process to guarantee that tolerance is within a reasonable scope, welding quality and air tightness of pipe connection structure are inspected by air tightness detector, and special quality problems with certain features are analyzed by image measuring instrument; after machining of pipe surface, some products are selected in random inspection for salt spray test to guarantee good appearance and quality.
Whole-process quality control guarantees not only exterior quality, but also performance quality of all kinds of products. Our company has been a leading supplier in automobile industry, and has been rated as a qualified supplier by China National Heavy Duty Truck Group for a consecutive five years, and has enjoyed exclusive supply right.
Our company has full-automatic digital pipe-bending equipment, which is the most advanced technology worldwide. The minimum bending radius is 0.8D. Compared with the common bending radius (1.5D), the 0.8D radius provides more space for finished automobile assembly and avoids disturbance point; reduction rate ≤20%, for example, thickness of a pipe with original thickness of 2mm is still more than 1.6mm after bending; servo motor is applied for control. Compared with previously used hydraulic system control, servo motor features a more sophisticated control capacity and higher degree of automation. All commissioning, lubrication and other works are done by computer control, which improves safety of workers. The servo motor can be remotely controlled.
3D robot laser cutting machine is applied to pipe cutting. Compared with traditional metal circular sawing machine or plasma cutting, it features simple and convenient operation. Operator only needs to set up machining parameters of products before cutting process to ensure precise operation. Laser cutting produces fine cutting edge and effectively guarantees perpendicularity of cutting edge with cutting error of 0.01mm.
Pipe end processing applies pipe end forming machine for forming. Parameters are set by computer during production. Pipe end is bended and formed in one time. Compared with integrated welding model and flange connection model widely used by domestic manufacturers, pipe end forming features simple process, smooth appearance, convenient connection, uniform angle of two ends and 100% air tightness. Installation angle can be adjusted to facilitate finished automobile assembly.
All pipe fittings and flanges are welded by Panasonic robots to fully guarantee appearance and quality of welding. Processing of exterior surface of products is done by assembly line.
Our company introduces production equipment of metal flexible pipes from abroad and applies imported raw material for processing, which guarantees high flexibility, air tightness, mechanical shock resistance and other performance of products and extend service life. Our product quality meets international standards and our company enjoys a bright development prospect. We believe that in the near future, our company will become stronger and witness a better development.
