The fitting degree of sheet metal parts during loading is also a key point to distinguish the quality of sheet metal parts. It will determine whether the final effect of loading is beautiful or not, and at the same time determine the difficulty of installation. Therefore, it is also a factor that many sheet metal maintenance technicians are very concerned about. If the fitting degree of sheet metal parts and the original car is low, such as the hole position cannot be aligned, the error of loading clearance and flatness is too large (the one-way tolerance of high-quality sheet metal parts in this respect should be controlled below 1.0mm), it can be basically judged that this is a non-conforming product from a small factory. Mr. Luo said that few car owners have noticed that a strong collision will cause slight deformation of the whole car body. At this time, if you install the sheet metal parts with large clearance, it will cause the car body to deform again, affecting the recovery of the damaged vehicle to its original appearance and quality.

There are two kinds of surface treatment methods commonly used in the processing of automobile sheet metal parts: electroplating and spraying. Electroplating is divided into galvanizing, nickel plating, chromium plating, etc. the main purpose is to form a protective layer of metal or alloy on the surface of sheet metal workpiece by using the principle of electrolysis, which plays a role of protection and decoration. Spray can be divided into spray painting and powder spraying. After the material parts are pretreated, the spray gun gas is used to disperse the coating into uniform and fine droplets, which are sprayed on the surface of the body work piece to form the coating on the surface of the work piece, and then heated and dried. Spraying can protect the workpiece. In addition to the above two methods, there are some other surface treatment methods, such as anodizing, chromate, wire drawing, sandblasting and oxidation.

当许多用户设计新产品或用于汽车冲压件的产品时，他们通常只在初期阶段就关注产品的开发和开发或价格，而没有过多地关注与注塑模具制造商的沟通和沟通。实际上，在确定产品的初步设计方案后，非常有必要与注塑模具制造商进行事先沟通。今天，我们将为您提供具体信息。介绍了打开注塑模具的注意事项。

It is said that the workers who make Lexus can feel the slight difference in the car body by hand. It is very difficult for us to reach the same level without professional training. But you should not worry too much. After all, a car that meets the factory standard is not easy to have the defects visible to consumers. Secondly, we also need to observe the clearance and smoothness between the various panels.

产品重量是衡量钣金零件质量的检验标准之一。为了确保汽车的安全，用于汽车钣金零件的钢板必须达到一定的重量。原始钣金零件和高质量副产品的重量应该几乎相同，并且如果您购买的钣金零件比原始钣金零件轻三分之一，那么您无疑会购买小型工厂产品。

汽车钣金零件广泛应用于我们生活的各个领域，包括一些电子设备，汽车零件，装饰材料等。 金属汽车冲压件的测量方法：金属冲压件的孔测量按照常规的量规测量方法取小的值。使用卡尺测量进行记录时，通常可以记录较小的值（不包括因太小而引起的误差，类比测量误差）（不包括特殊情况）。记录大值和平均值没有实际意义，并且测量各个方向上的孔径大小也没有实际意义。差异应记录在几何公差的圆度上，而不是在光圈中。

In the industrial field, different production processes will have a great impact on the performance of products. So, for the processing of stainless steel stamping parts, what are its processing characteristics and advantages? Next, automotive stamping parts manufacturers will analyze and answer this question, hoping to help you.

China's automobile industry is in an important period of development. Building a strong automobile country will become a national development strategy. Green, environmental protection, high efficiency and safety are the development trend of automobile industry. In order to realize the transformation, upgrading and development of automobile industry and improve the overall development level of automobile industry, China has proposed to vigorously develop energy-saving and new energy automobile industry. China's automotive parts industry must coordinate with the transformation and development of the entire automotive industry. In the future, it will focus on the development strategy of parts, transformation and upgrading, policy research, technological innovation, standards and regulations, zero cooperation, common platform construction, industrial internationalization, industrial cluster development and practical services.

汽车零件用拉伸油属于金属加工油，适用于超高强度拉伸成型，管材拉伸，冲剪，拉削等。冲压和拉伸油分为水溶性，金属和铝压印和绘图油。

仔细观察生产的汽车冲压零件，会发现产品的表面是凹凸的，从而影响了整个工件的质量。为了改善这种情况，我们必须首先找到问题的根本原因，以便制定相关的解决方案。冲压零件制造商也意识到了这个问题的严重性，因此他们开始进行改进。

In our life, we often rust our daily necessities for some reasons, but there are the same problems in my sheet metal processing console. Because of the storage problem, when we put the sheet metal processing console in the basement, its humidity will be relatively high. After being damp, we should timely carry out moisture-proof and moisture-absorbing work on it.

In the production process of automobile sheet metal parts, there are certain requirements for stamping technology and stamping die. In high-speed stamping equipment and multi-function stamping die, only "high-speed" and "multi-function" can not meet the production requirements, only to achieve continuous conveying of sheet metal to stamping machine and stamping die, and stamped sheet metal workpiece can be removed from the stamping die and conveyed to the next stamping worker in a very short time. In order to realize the economic benefits of the theory, we should pay more attention to the time. Therefore, the correct stamping process should be: careful analysis and research of the whole stamping process of sheet metal parts, to ensure that the whole process from the beginning of sheet metal feeding to the completion of sheet metal parts processing, has the expected shortest production rhythm, so as to achieve the best efficiency.

Opportunity One: High Growth of Domestic Automobile Market "In the next ten years, China's demand for automobiles will remain at an average annual growth rate of 13%-15%. Compared with the world's automotive powers, China's automotive market has a relatively long period of rapid growth. This period is probably from 2009 to 2023, spanning about 15 years. This is a period for all domestic spare parts enterprises. Good opportunities for development."

钣金零件很薄且易于成型。它们可以形成各种形状的部分。通过焊接，装配和铆接技术的应用，有可能实现产品的多结构化。同时，这些特性使钣金零件在加工过程中或多或少地变形，例如弯曲变形，扭转变形，凹凸变形等。这些变形使整个组件的尺寸或形状发生变化，从而导致质量问题。但是，钣金零件的生产过程具有其固有的规律。对于相同类型的产品，可以根据现有设备，人力等灵活地调整加工顺序，并给出合理的加工工艺。因此，选择正确的技术路线是预防和解决此类问题的有效措施。

所谓钣金，是指通过钣金技术加工的产品。钣金已广泛应用于我们的日常生活中。金属薄板具有重量轻，强度高，导电性好（可用于电磁屏蔽），成本低，批量生产性能好的特点。使用过程中常见的问题是表面生锈等。问题。

为了区分汽车钣金零件的质量，我们可以从包装，重量，焊接过程，喷漆过程以及装载时的重合度入手。普通车主在交车后很难区分钣金零件是否是高质量的。他们还可以事先将其与产品包装区分开。通常，由小工厂生产的产品不会打印联系方式和工厂地址，但即使将来消费者使用它们，产品也将带有钢印，资格证明和测试标签。当出现问题时，也可以有一种维护权利的方法。

Spray painting of automobile sheet metal parts is an operation with professional skills. In operation, attention should be paid to the uniformity of the spray paint, the smoothness of the paint surface, and whether the color of the spray paint is consistent with the color of the car body. Therefore, when our car bumps into the need for spray painting, we should first understand that spray painting of automobile sheet metal should pay attention to one. Some things, in order to do services will not be pitted, then what matters need attention?

说到金属冲压，我相信许多机械，汽车，电子，五金等行业都得到了应用，金属冲压可以使产品成型更好，但是每次冲压完成后，我们都需要清洗，如何清洗冲压零件对于五金汽车，这是许多企业想知道的。

Because the brake pads of automobile parts are consumables, the more driving kilometers, the worse the wear of the brake pads. When the wear reaches the critical point, it must be replaced.
