Punched and bent processing piece

Production Process: Core CNC Bending + Integrated Supporting Processes

We take precision CNC bending as the core process, matching with precision stamping and post-processing technologies to form a full-cycle production chain, ensuring efficient production and product adaptability to diverse industrial scenarios:

• Core CNC Bending Technology: Equipped with 20+ sets of high-performance CNC bending equipment (35 tons–400 tons) with intelligent angle compensation systems. It achieves bending precision of ±0.5°, angle repeatability of ±0.1°, and can flexibly process complex shapes (U-bend, V-bend, Z-bend) for various workpieces. The equipment is suitable for metal materials with thicknesses of 0.8mm–15mm, perfectly meeting the load-bearing and assembly requirements of punched and bent parts in industrial applications.

• Supplementary Processes: Precision stamping is integrated for high-accuracy blanking and hole-drilling, ensuring pre-processing precision of raw materials. Post-processing includes automatic welding (structural reinforcement) and professional surface treatment, further enhancing corrosion resistance and service life. The integrated punching-bending process shortens production lead times and improves dimensional consistency of batch products.

FAQ

Q1: How do you ensure quality?

A: We have a fully equipped quality inspection center, complete testing equipment, and a strict ISO 9001 quality management system. Each sheet metal stamping part is tested for dimensions, mechanical properties, and surface finish before delivery to ensure stable quality and compliance with international standards.

Q2: What are the prices of the Sheet Metal Stamping Parts?

A: Prices depend on several factors, including raw materials, tolerances,  surface treatments, and order quantity. Since Xinlongji Metal  owns and manages integrated stamping factories, we can provide competitive real-time quotations while maintaining stable product quality for every batch of custom sheet metal parts.

Q3: How can I get a better price?

A: All our prices are based on high-quality standards. With the same material and precision, our sheet stamping parts are more cost-effective because of supply chain integration. Larger orders or long-term cooperation projects can help you obtain even better prices and stable supply support.

Q4: What's the MOQ for Sheet Metal Stamping Parts?

A: MOQ depends on product size, complexity, and raw material type. You can send us 2D or 3D drawings, and we will evaluate production feasibility and confirm the MOQ. Xinlongji Metal guarantees flexibility for trial runs and supports small batches for initial testing.

Q5: What is your delivery cycle?

A: Delivery time is typically around 30 days. Complex parts or larger orders may require slightly longer schedules. Our integrated factories coordinate production, packaging, and shipment efficiently. In most cases, we can complete orders within 45 days while ensuring consistent quality and timely delivery.

Q6: What surface finishes do you offer?

A: We offer powder coating, galvanizing, anodizing, sandblasting, and more through long-term partnerships with surface treatment factories. Surface finishing choices depend on material, environment, and functional requirements. Xinlongji Metal provides the most suitable solution for every sheet metal stamping part based on its intended application.

Q7: Which countries do you ship to?

A: Qingdao Xinlongji Metal Manufacturing Co., Ltd. exports sheet metal stamping parts to more than 60 countries across Europe, North America, South America, Africa, and Southeast Asia. Our logistics team ensures timely shipping and helps clients manage customs procedures and freight costs effectively for each destination.

Q8: What size Sheet Metal Stamping Parts can you produce?

A: Our 800-ton punching machine supports various part sizes. The feasible dimensions depend on material, thickness, shape, and process complexity. You can send us 2D or 3D drawings (NDA available), and we'll evaluate production feasibility and provide a cost-effective solution for your project.

Q9: What information do I need to provide to get a quote?

A: Please provide:
