How Does A Stamping Factory Maintain Old Customers
The hard-won customers of the metal stamping factory, in addition to developing new customers, also need to maintain regular customers. In the metal stamping industry, well-maintained old customers are often more important than developing new customers. So for metal stamping manufacturers, what needs to be done to maintain old customers?1. Good after-sales serviceMany stamping parts manufacturers changed their attitudes after signing the contract and receiving payment. They spend all their energy in the customer development stage. They don't know that after-sales service is also a point that customers value very much. Customers definitely don't want to cooperate with such a stamping factory. In order to retain customers and long-term benefits, good after-sales service and active problem solving are the basis for maintaining old customers.2. Keep proper contactCustomer relationship needs to be maintained. Don't wait until there is an order to contact customers. Maintaining proper contact is mainly to deepen the customer's memory of you. Of course, this kind of contact should not be too frequent, too frequent may make customers feel disgusted.3. Some greetingsThere are many ways to greet old customers, including: text messages, phone calls, door-to-door visits, giving suitable small gifts and so on. In addition, some dinners, tea parties, etc. can be held at appropriate times to invite customers to participate, which can fully demonstrate our importance to customers and shorten the distance with customers.

What Are The Characteristics Of The Metal Stamping Workshop
Precision metal stamping parts are an indispensable part of automobile production. Stamping process is one of the four main processes in automobile production, and its status is particularly important. The stamping workshop is the basis for the operation of other workshops, including the subsequent surface treatment and assembly workshops. For general production, the stamping workshop has high technical requirements, large process complexity, large investment scale, many production equipment, and long manufacturing cycle.1. Production line layout of stamping workshopThe stamping workshop arranges corresponding production lines according to the production capacity of the entire factory. Due to the different stamping parts required by the product, the number of steps required to process metal stamping parts is also different. According to the different production processes of metal stamping parts, the stamping line can be divided into stamping lines of different tonnage. Generally, each production line needs to produce different metal stamping parts according to the different tonnage of the press, and these metal stamping parts need to be suitable for production on the production line. Because each stamping production line needs to produce several different types of processes, and the punch tonnage required for each process is different, different tonnage punches should be allocated to each production line.2. The process of stamping parts is complexThe various metal stamping parts needed for production, except for some semi-finished products purchased from outside, are all produced by our own stamping workshop. The production of each metal stamping part usually goes through multiple processes, mainly including uncoiling and blanking, stretching, trimming, stamping and flanging, etc. Among them, uncoiling blanking is to place the plate on the blanking machine before stamping production, and process it into a geometric shape suitable for stamping production. Different stamping parts require different production processes, and different production processes require different molds for processing. Since each metal stamping part has a fixed production process route, the complicated process route for producing the metal stamping part makes it difficult to arrange production.3. Production line with both ends at the same timeAccording to the process requirements of the stamping production line, when arranging different tonnage punches in each process, the high, medium and low tonnages are generally arranged from both ends to the middle. In this way, two-way production can greatly improve the production efficiency of the stamping workshop and the utilization rate of the punch, thereby reducing production costs.4. Batch productionWhen the stamping shop produces metal stamping parts, it does not produce one product at a time, nor does it produce all the stamping parts planned to be produced in the production cycle. Instead, it considers the replacement time of production molds, the number of plate cuts and the economy. On this basis, mass production is carried out. Mass production refers to dividing the metal stamping parts planned to be produced in the production planning cycle into several batches according to production needs. Each batch is produced every day, and the numbering is completed in the planning cycle. The advantage of mass production is that it will not make the production time of a single batch of metal stamping parts too long, will not affect the production of other metal stamping parts, which will lead to the use of downstream workshops and reduce production costs.

The Reason Why The Size Of Stamping And Bending Parts Does Not Meet The Standard
Stamping and bending parts are a very common metal stamping part. In actual production, the appearance and size of stamping and bending products often do not meet the standards on the drawings. So, what is the reason if the shape and size of the processed stamping parts and bending parts do not meet the standard?1. Stamping die problemStamping Bending dies are tools for bending stamped parts. Generally, the shape and size of the bent stamping part depends on the size of the working parts of the stamping die. The more precise the size of the stamping die is, the more precise the shape and size of the stamping and bending parts. In addition, the reliability of the pressing device and positioning device used in the stamping die structure will also have a greater impact on the shape and size of the bending part.2. Raw material issuesDifferent raw materials will also affect the shape and size of stamping and bending parts. There are two main reasons: 1. The material's mechanical properties and composition distribution are not uniform. For stamping parts that are bent on the same plate, the shape and size of the stamping parts are different due to the different pressure and springback values; 2. The uneven thickness of the material will also affect the size and shape of the stamping and bending parts.3. Bending process issuesAs the number of processing steps of stamping and bending parts increases, the errors caused by the accumulation of deviations caused by each step also increase. In addition, if the sequence of the process is different, the size will also be greatly affected. For example, for a bent part with holes, when bending first and then punching, the shape and position of the holes are much higher than when punching and then bending.4. Punch problemWhen bending, different punch models, different tonnages, and different operating speeds will affect the size of the stamping and bending parts. In addition, the size of the punch itself will also have a certain impact.

What Should I Do If There Are Scratches On The Surface Of The Stamping Part?
With the improvement of science and technology, people have higher and higher requirements for precision stamping products. There are many problems that plague stamping parts manufacturers, and scratches on the surface of stamping parts are one of them. It is difficult to avoid scratches on the metal surface of precision metal stamping parts, whether it is in production or after production, packaging, etc., so how should we deal with the surface scratches of stamping parts?1. The raw material is scratched. Those with poor raw materials and scratches should be used with caution. For those who need baking varnish or other surface treatment, you need to know the position of baking varnish or surface treatment. If the scratches are severe, please carefully consider whether to continue using it.2. The loading personnel were scratched when loading and unloading materials. When loading and unloading, two people need to pick up and put down vertically at the same time. It is recommended to use a brush workbench. If it is a ball table, you need to lay down the balls of the machine table. When filing burrs, it is not allowed to pile the materials together, and it is not allowed to drag the stamping parts onto the cardboard. They should be placed smoothly and neatly, the number of each layer is the same, and the height should not exceed one meter.3. There are scratches on the mold. The brush in the cutter head should not be too short and should be slightly higher than the surface of the lower die of the cutter head. Thick plates need to use hard brushes, special forming tools have higher lower molds, and use assembly and disassembly production. The program can be optimized to reduce the drag of the workpiece on the mold.4. There is a problem in the process of stamping oil feeding. Check whether the oil supply device is blocked and whether the processing oil is completely covered. Replace the current stamping processing oil and choose a special stamping oil containing sulfurized extreme pressure additives.
