Schaeffler was awarded the “Supplier Quality Excellence Award 2013†​​by GM China for its wheel bearing products manufactured by the Taicang factory. This is another award in the field of product quality of the Schaeffler Greater China Automotive Division after winning the Best Quality Award from Changan Ford Mazda in 2012. A total of 65 domestic and foreign auto parts suppliers participated in the GM China Supplier Awards 2013 Excellent Supplier Award Ceremony. Schaeffler Greater China was the only wheel bearing supplier awarded the Quality Excellence Award. Marcelo Machado, Vice President of Schaeffler Greater China Automotive Division Chassis Division, received the medal from Grace Lieblein, General Motors Vice President of Global Purchasing and Supply Chain. Wheel bearings for GM are produced at the 3rd plant of Schaeffler Taicang. Taicang No. 3 Plant is Schaeffler's important production base for automobile wheel bearings. In addition to supplying general-purpose products, it also supplies many important domestic and foreign automakers, including Volkswagen and Changan Ford, and the localization rate exceeds 98%. With first-class product quality, good customer service and fast reaction support capabilities, Schaeffler is highly recognized by customers such as General Motors. Schaeffler always regards "zero defects" as the only quality standard, and 2013 as "Schoeffler China Quality Year", committed to providing customers with the best quality products and services. During the injection molding process, when the molten plastic meets in the form of multiple strands in the cavity due to the holes in the insert, the areas where the flow rate is discontinuous, and the area where the filling material flow is interrupted, a linear weld seam is produced because it cannot be completely fused. In addition, when the gate injection molding occurs, a weld seam will also be formed, and the strength and other properties of the weld seam are poor. The main reasons are as follows: Pvc Injection,Precision Plastic Injection Mould,Oem Plastic Injection Crate Mould,Plastic Injection Mould Suzhou Dongye Precision Molding Co.,Ltd. , https://www.sjinjectionmolding.com
Schaeffler Wins GM's 2013 Quality Excellence Award
Processing:
The injection pressure and speed are too low, and the barrel temperature and mold temperature are too low, resulting in premature cooling of the molten material entering the mold and the appearance of weld seams.
When the injection pressure and speed are too high, injection will occur and weld seams will appear. The speed should be increased, and the back pressure should be increased to reduce the viscosity of the plastic and increase the density. Plastics should be dry well, recycled materials should be used sparingly, and weld seams may occur if the amount of release agent is too much or the quality is not good. Reduce clamping force and facilitate exhaust.
2. Mould:
If there are too many gates in the same cavity, reduce the gate or set it symmetrically, or set it as close as possible to the weld seam. The exhaust at the weld seam is poor, and an exhaust system should be set up. The sprue is too large, the size of the gating system is improper, and the gate is opened to prevent the melt from flowing around the insert hole, or use as few inserts as possible. If the wall thickness changes too much, or the wall thickness is too thin, the wall thickness of the workpiece should be uniform. If necessary, a fusion well should be opened at the fusion seam to separate the fusion seam from the workpiece.
3. Plastic aspects:
Lubricants and stabilizers should be appropriately added to plastics with poor fluidity or heat sensitivity. Plastic contains a lot of impurities, if necessary, replace the plastic with good quality.
