Product Display
Adapt to aluminum sheet characteristics and ensure forming precision and surface quality: Aluminum sheets have good ductility but are prone to scratches. By optimizing cavity finish (e.g., mirror polishing) and reasonably designing die clearance, aluminum sheet drawing dies can reduce friction between materials and the die during the drawing process, avoid surface scratches, and accurately control the amount of drawing deformation to ensure the forming precision of aluminum sheet workpieces.
Low wear and long service life, improving production efficiency: Aluminum sheets are lower in hardness than materials such as stainless steel, causing less wear to the die. Combined with high-quality die steels like SKD11/CR12MOV and targeted heat treatment processes, the die has a lower wear rate and longer service life, reducing die change downtime and adapting to the needs of mass stretching production of aluminum sheets.
FAQ about this product
Q: What are the mold-related reasons for wrinkling and cracking problems that easily occur during aluminum sheet drawing? How to solve them?
A: The core reasons include unreasonable mold clearance, improper fillet design, and insufficient surface finish. Solutions: ① Precisely set the mold clearance to 8%-12% of the aluminum sheet thickness to avoid cracking caused by excessive friction between materials due to too small clearance or wrinkling caused by too large clearance; ② Optimize the fillet radius of the cavity and punch (R2.5-R4.0mm is recommended) to disperse drawing stress and reduce material tearing at sharp corners; ③ Perform mirror polishing on the mold cavity to reduce material sliding resistance and avoid surface scratches.
3. Q: What key information needs to be provided to the manufacturer when customizing aluminum sheet drawing dies?
A: Four core pieces of information need to be clarified: ① Aluminum sheet parameters (material grade, thickness range, such as 0.1-5mm conventional aluminum sheet or thick plate); ② Workpiece requirements (2D/3D drawings, drawing forming precision requirements, such as ±0.01-0.05mm); ③ Production process (cold drawing/hot drawing, single-process/progressive drawing); ④ Production capacity and working conditions (monthly output, drawing speed, whether it needs to be adapted to automatic production lines), to ensure that the mold design accurately matches the actual production needs.
4. Q: How to maintain aluminum sheet drawing dies to extend their service life?
A: Focus on three key points: ① Preheating and cooling: Preheat the mold to 150-250℃ before use (suitable for hot drawing process) to avoid cracks caused by direct stress at low temperatures; let it cool naturally after production, and prohibit sudden cooling with cold water; ② Daily cleaning: Regularly clean residual aluminum chips in the cavity to avoid wear on the cavity surface; ③ Regular maintenance: After producing 5,000-10,000 pieces, check the mold dimensional accuracy and surface wear, polish and repair worn parts, and re-perform nitriding treatment if necessary to enhance surface hardness.
