Dongguan Qiren Electronics is a leading China-based manufacturer of precision Metal Stamping And Drawing Parts, specializing in high-performance solutions for industries like automotive, aerospace, and consumer electronics. Utilizing advanced EDM stamping technology, Qiren achieves ±0.003mm cavity accuracy and Ra0.1μm surface roughness, tackling extreme challenges such as 15:1 depth-to-diameter military-grade shells and 0.05mm ultra-thin foil processing.
The metal stamping department of Dongguan Qiren Electronics Co., Ltd. has an experienced metal stamping and stretching die design and manufacturing team, which can provide customers with full technical support. We are proficient in the structural analysis, material selection and process optimization of various metal molds to ensure the performance and service life of the mold. Our production equipment includes high-precision punching machines that can meet the precision needs of different industries. From design verification to mass production, we provide professional services throughout the process to ensure that customers get the best mold solutions.
In the battlefield where the new energy battery shell is scrapped if it wrinkles 0.1mm, and in the ultra-thin mobile phone middle frame stretching ratio exceeds the death line of 8:1, the EDM stamping die process is using a cavity accuracy of ±0.003mm to make the 6061 aluminum alloy stretch as smooth as silk!
When traditional wire cutting leaves fatal burrs on 1.2mm thick titanium alloy, and when CNC milling causes stress cracks at the rounded corners of the stretching die, our 8-axis intelligent EDM system is using 0.03mm electrode wire to carve a R0.05mm stretching flow channel on 62HRC carbide that is smoother than baby skin! Automotive cover molds, folding screen hinge modules, nuclear-grade sealing ring punching dies... These "hell-level orders" that once made Swiss stamping experts throw wrenches are now delivered within 48 hours with zero rework!
● Pulse nano-scalpel: 0.00001 second discharge precision excision, tensile die surface roughness directly rushes to Ra0.1μm
● Intelligent material thickness compensation system: real-time perception of sheet flow, dynamic correction of cavity gap accuracy locked ±0.002mm
● Ultra-deep drawing annihilator: specializes in military-grade shells with a depth-to-diameter ratio of 15:1, and material thinning rate is controlled ≤3%
● Stress field reconstruction black technology: AI simulates metal flow trajectory, completely eliminates tensile cracking and wrinkling
● Trillion-time life matrix: multi-layer gradient coating technology, mold life soars to 8 times that of traditional processes
A global TOP3 home appliance brand stainless steel steam oven inner mold requires 0.8mm sheet material to be stretched to a depth of 120mm without orange peel. The yield rate of traditional processes is only 18%. We launched a multi-air gap EDM solution and achieved a 98.5% yield rate in three days, forcing back the German supplier's ten-year technical barriers!
From 0.05mm ultra-thin foil to 12mm armored steel plate, from special-shaped heat sink fin mold to rocket fuel tank mold, 13,527 sets of extreme cases roar: When traditional stretching processes collectively collapse, EDM is the dimensional blade that tears the laws of physics!
