6. What to do if stretched parts are prone to cracking?

A: Adjust the stretching gap, increase the fillet radius, increase the blanking force, anneal and soften the sheet metal, and apply stamping oil for lubrication.

Key features

Cutting, bending, and stretching can be completed in a single stamping process, enabling fast mass production and making it suitable for mass production of parts, significantly reducing labor time.

Mold-based molding ensures high product consistency and controllable tolerances, meeting the high-precision requirements of automotive parts, home appliances, and new energy components.

Capable of producing deep and shallow stretching, irregular curved surfaces, multi-folded edges, and punching in one piece, enabling integrated fabrication of complex sheet metal parts.

After initial mold making, the cost per piece is extremely low, with minimal material consumption and simplified processes. Large-scale production offers significantly better cost-effectiveness than m

High-quality quenching dies are wear-resistant and impact-resistant, and can withstand hundreds of thousands of stamping cycles.

Covering the entire field of automotive chassis, home appliance housings, hardware accessories, medical devices, and precision electronic components.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier engaged in aerospace components, molds, stamping parts, hardware, automation equipment, production lines, and industrial robots. It provides 3D software design, ODM, OEM, and multiple customization options. Evidence also shows new product development, cooperation with colleges and research institutes, and a sheet-metal forming technology research base. Service management procedures cover corrective actions, customer complaints, supplier assessment, and quality assurance. However, the supplier lacks an available SDK, overseas agents or branches, overseas warehouses and showrooms, in-stock capability, and a valid manufacturing-capacity contract with related subcontractors. An ISO9001:2015 certificate and regular fire drills are reported, but no factory environmental impact assessment report is available.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated business scope covers aerospace product components, molds, stamping and hardware products, automation equipment, production lines, and industrial robots, indicating a technically oriented manufacturing and engineering profile.

CertificationsThe supplier reports holding an ISO9001:2015 certificate, which provides explicit evidence of a quality management certification. However, the available information does not establish other certifications.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, and its overseas service offerings include installation, training, repair, maintenance, and debugging. Nevertheless, it has no overseas agents or branches, no overseas warehouse or showroom, and no in-stock capability, which limits the breadth and local responsiveness of after-sales support.

R&D capabilityThe supplier provides 3D software design, has developed new products during the past year, offers ODM services, and describes cooperation with colleges and research institutes, including a sheet-metal forming technology research base with six professors and postgraduates stationed long term. The absence of an available SDK is a limitation but does not negate the documented product and process innovation activities.

Production capacityThe business scope includes manufacturing aerospace components, molds, stamping and hardware products, automation equipment, production lines, and industrial robots, with stated average lead times of within 15 working days in the off-season and one month during peak season. However, the supplier reports no in-stock capability and no valid manufacturing-capacity contract with its related subcontractor, so production capacity is supported but not comprehensively verified.

Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. It also provides 3D software design and ODM services, directly supporting a broad customization offering.

Product Q&A

Q:1. What materials are commonly used to make stamping dies?

A: Commonly used materials include Cr12MoV, SKD11, DC53, H13, and 45# steel. Precision high-speed dies often use high-hardness alloy steel.

Q:2. What materials are suitable for stamping dies to process?

A: Cold-rolled steel, hot-rolled steel, stainless steel, high-strength steel, aluminum alloy, copper strip, galvanized steel, aluminized steel, and other types of metal sheets.

Q:3. What is the achievable precision of stamped parts?

0.01mm-0.03mm

Q:4. How long does it take to make a set of stamping dies?

A: Simple dies: 7-15 days; Medium-complex dies: 15-30 days; Precision continuous drawing dies: 30-60 days.

Q:5. What is the typical lifespan of a mold?

A: Ordinary molds: 100,000-300,000 cycles; heat-treated precision molds: 500,000-1,000,000 cycles or more. With proper maintenance, the lifespan can be even longer.
