Custom Ventilation shutter profiles

Punching and bending are key steps in the processing of blinds. How does your company control the parameters of these processes to ensure the quality and precision of the holes, as well as the smoothness and angle accuracy of the bends?

During the processing of blinds, punching and bending are two core process steps that are directly related to the final quality and performance of the product. As a company with a global reputation and whose product quality has been recognized by many well-known certification bodies, we are well aware of the importance of every detail, especially when dealing with aluminum blinds, which require extremely high precision and durability. Our products have not only obtained EC type examination certificates, BV MODE, DNV GL certificates, EC conformity certificates, marine product type approval certificates and Lloyd's Register quality assurance, but have also been widely used and verified in many fields such as industrial machinery, construction machinery, ships and deck machinery, offshore equipment, mining and metallurgical machinery. These certifications and practical application experience provide us with deep technical accumulation and strict quality control system to ensure that the punching and bending processes meet the highest standards during the processing of blinds.
1. Precision design and simulation
Before punching, we use advanced computer-aided design (CAD) and computer-aided manufacturing (CAM) software for precise design, and use simulation software to simulate the punching position, hole size, hole spacing, etc. many times to ensure that the design meets the actual production needs and reduce errors. Our design team, especially the research team focusing on aluminum door and window profiles, curtain walls and industrial profiles, has rich experience and can accurately predict the material deformation during the punching process, so as to optimize it in the design stage and avoid quality problems in actual production.
2. High-precision equipment application
Punching operations rely on top equipment in the industry. We are equipped with advanced CNC punching machines, which are driven by servo motors and can achieve high-precision positioning and punching. By setting precise parameters such as punch speed, punching force, feed speed, etc., we ensure that each punching can meet the design requirements. In addition, we also regularly calibrate and maintain the equipment to ensure that it is always in the best working condition.
3. Process monitoring and testing
Every time a batch of punching operations is completed, we will conduct strict inspections. Use high-precision measuring tools, such as image measuring machines, to conduct 100% inspection of hole size, hole spacing, and hole position accuracy to ensure that all holes meet the design requirements. For customers with special requirements, we will also conduct additional inspections according to international standards and customer-specific requirements to ensure foolproof product quality.
Parameter control and quality assurance of bending process
1. Material property analysis
Before bending, we conduct an in-depth analysis of the material properties of aluminum ventilation shutter profiles, including key indicators such as yield strength, tensile strength, and elongation of the material, in order to select appropriate bending process parameters. Our team has many experienced technicians who are familiar with the characteristics of different aluminum alloy materials and can accurately judge the bending performance of the material, so as to develop the best bending plan.
2. Bending mold design and manufacturing
The accuracy of the bending mold directly affects the smoothness and angle accuracy of the bent part. We use advanced mold design and manufacturing technology to customize high-precision molds according to the cross-sectional shape and bending requirements of the profile. The mold material is made of high-quality alloy steel, which is precision machined and heat treated to ensure the hardness and wear resistance of the mold, thereby extending the service life and ensuring the stability and consistency of the bent part.
3. Bending process control
During the bending process, we use CNC pipe bending machines to achieve automated bending by setting precise bending angles, bending radius, pushing speed and other parameters. At the same time, we monitor the stress changes during the bending process in real time, and adjust the parameters to avoid excessive stretching or compression of the material to ensure the smoothness and angle accuracy of the bent parts. In addition, we also use equipment such as metallographic microscopes and Vickers hardness testers to test the microstructure and hardness of the bent materials to ensure that the material properties are not affected.
4. Finished product inspection and feedback
After the bending is completed, we conduct strict inspections on each product, including the accuracy of the bending angle, the smoothness of the bending part, the surface quality, etc. The geometric dimensions of the bent parts are accurately measured using a three-dimensional coordinate measuring machine to ensure that all indicators meet the design requirements. For the problems found, we immediately conduct traceability analysis, adjust the process parameters, and continuously optimize the production process to ensure the stability of the quality of subsequent production batches.
