What Are The Defects Of Automobile Press Parts

The auto stamping industry is getting more and more attention because the industry is continuously developing. In order to ensure that all aspects of auto stamping meet the standards, it needs to be inspected.  The corresponding inspection method is basically the same as that of other products. Among many inspection items, the inspection of defects and hardness needs to be emphasized.
There are many forms of defects in stamping parts, including craters, pockmarks, scratches, cracks, wrinkles, deformation, holes and so on. Relevant parts inspection instructions shall be used as controls during inspection.  Secondly, special inspection tools must be used skillfully.  There are also samples.
As the main material of Automobile Press Parts is die steel, the hardness value of the sample can be determined by testing the difference between its initial speed and the speed after rebound.  Moreover, due to the different thickness of the surface layer of stamping parts, the obtained results are necessarily different.
As a professional Welding Parts Suppliers, nbstarlite has a great say in this aspect. We can better meet your needs, so please contact us if you are interested.

Process Classification Of Automobile Press Parts

As a Welding Parts Suppliers with many years of production experience, nbstarlite today gives a brief introduction to the production process of automobile press parts: stamping parts can be divided into blanking and forming according to the process.  Blanking is to blank the required blank from the steel plate according to the shape and development size of the part. This process mainly needs to control the smooth fracture surface and small burrs.  The smooth finish of convex and concave line cutting is one of the reasons that affect the smooth finish of the fracture surface of stamping parts. Excessive or too small die clearance will produce burrs. Therefore, designers should determine reasonable clearance according to product characteristics and plate thickness when making stamping dies. In addition, positioning must be accurate when assembling.

Stamping includes bending, stretching, etc. In this process, attention should be paid to cracking and breaking of stamping parts.  The bending and cracking of stamping parts may be related to the hardness of the plates used and the radius of the round corners of the dies. If the design allows, the plates with low hardness can be selected or the radius of the round corners of the forming dies of stamping parts can be increased, and the grain direction of the plates should be paid attention to so as to achieve good results.

At present, Automobile Press Parts have been widely used. If you have any demand in this field, don’t miss nbstarlite.

Nbstarlite Welding Parts Suppliers Advantage Introduction

Common Automobile Press Parts include: instrument panel body frame, battery bracket, front module, control box, seat support frame, placenta, fender, chassis cover plate, noise partition plate, rear door frame, etc.  The panel of automobile stamping parts is mostly made of engineering plastic abs or abs/pc.

Generally, door trim, instrument panel, bumper and fender are basically made of pp, while engine hood is made of PP plus lead. pc/abs is generally purchased from material manufacturers.  Plastic parts are light in weight, various in color, attractive in appearance, good in weight reduction effect, and capable of reducing the weight of the vehicle body itself.  Can be recycled and recycled for many times.

In automobile recycling, metal products and the like are mostly not of recycling value because they are too old and rusty.  However, plastic products can be melted again and recycled, and basically can be processed again after melting without any harm. Therefore, automobile stamping parts are more and more popular with big people.

Welding Parts Suppliers To Solve The Welding Problem Of Products

  1. Stomata.  When welding equipment is used in all-position welding, air holes are common problems in the welding process of Automobile Press Parts.  There are many reasons for this problem, such as welding material itself, improper operation, environmental reasons, etc.
    Solution: During welding, gas protection should be strengthened. The welding temperature should not be too high. Gas should be filled in strict accordance with the proportion and relevant requirements to maintain the filling purity.  At the same time, Welding Parts Suppliersshould pay attention to the environment around the welding site.  If the wind speed on the construction site exceeds 8 meters per second, the protective shed shall be applied, and the ambient humidity shall not be too high.
    2. Incomplete fusion.  In welding, the position of vertical welding usually results in incomplete fusion.  The cause of this problem may be the incorrect shape of the welding path, deviation from the weld seam in the welding process, or the unreasonable width of the welding torch.
    Solution: During the welding process, grinding and leveling shall be carried out as much as possible.  Before welding, carefully observe whether the width of welding wire is correct.  If there is a deviation between the welding pool and the welding center, it should be adjusted in time.
