Deep drawing is a stamping process that progressively draws metal sheet into cylindrical or box-shaped parts through dies. Fineforming achieves multi-stage deep drawing in progressive dies, excelling at forming complex geometries with high depth-to-diameter ratios.
Equipment & Capabilities
Our press equipment covers a tonnage range from 25T to 800T, including brands such as ASAHI-SEIKI, AIDA, KOMATSU, and CHIN-FONG precision presses. Processable material thickness ranges from 0.10–8.00mm, suitable for cold-rolled steel, stainless steel, aluminum alloy, copper alloy, and high-strength steel.
Process Characteristics
- Multi-stage continuous forming in progressive dies, completed within a single die
- High depth-to-diameter ratio housings formed without secondary machining on critical functional surfaces
- Real-time SPC process monitoring
- Applicable to airbag housings, sensor housings, flow meter housings, etc.
Deep drawing places extremely high demands on die design, material flow control, and lubrication management. Fineforming maintains 100% in-house die design and manufacturing capabilities, ensuring full-process quality control from engineering development to mass production delivery.
