2017 Frankfurt Auto Show in Chengdu

The 4th Chengdu International Auto Parts and Aftermarket Service (CAPAS) ended in May 27, 2017 in Chengdu New Century International Exhibition Center. As one of the top ten exhibitions in the southwest region, CAPAS's attention in the automotive industry is still not to be overlooked. With the advancement of the western part of the country and the establishment of the new Silk Road economic belt, more and more industry concerns are gradually turning to the southwest region with great potential for development. CAPAS is a large-scale international post-car market in the western region. Many people in the industry view the southwest as one of the most promising areas in China's auto industry. Chengdu is located in the heart of the southwest region and plays a role in promoting regional economic development. A strategic role. Many high-quality enterprises with product technology wonderful debut Chengdu Frankfurt Auto Show, including Bosch, Iveco and Changchun FAW, including the leading brands are all unveiled in order to further develop the Southwest market business. Chengdu as China's "all the way" strategy in the logistics hub, the local commercial vehicle industry is experiencing rapid growth.

The company is engaged in the research and development, production and marketing of the fuel injection system of the engine. The company has been engaged in the development of the fuel injection system. As the domestic oil pump nozzle industry benchmarking enterprises to promote the development of the industry as their duty, bold introduction of advanced management concepts and marketing model, the first to upgrade the brand, the future of the road is not only China's road through, it is the world's road through. Sichuan's economic vitality and market share in the automotive market after the important, Zhongtian company Frankfurt Auto Show in Sichuan, is also one of the company's important strategic plan. Next, the company will increase investment in the market in Sichuan, enhance the company's brand influence. Through this exhibition to show our customers products and image, strengthen cooperation with the new and old customers, the road will be willing to go all the way with you, mutual benefit and win-win future.

Pvc Injection

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:
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.
