What are the difficulties in designing stamping molds for irregular parts?

The dificulty of stamping die design for irregular parts involves many technical challenges and requires a combination of precisionmanufacturing experience and innovative solutions. Here are specific difficulties and how JS company's response strategies:

1.Design challenges posed by structural complexity

Difficulties:

• Split die design: Irregular parts usually require a multi-cavity die or slider structures with a high mold complexity (e.g. 7-8 slider linkage for car coverings).
• Core extractor: For deep stretching or lateral core extractor parts, precision core is needed, otherwise mold jamming or size deviation may occur.
• Mold strength: Complex structures are prone to stress concentration and topology optimization is required to improve stiffness.

Response strategies:

• Modular design and individual manufacturing of key components.
• The force distribution of die is optimized by FEA.

2.Material utilization and layout optimization

Difficulties:

• Irregular parts are prone to waste layout process, resulting in material utilization rate less than 60%.
• Complex contours require a balance between stamping sequence and deformation control.

Response strategies:

• Samples are automatically optimized and arranged using AI algorithms.
• The universal edge cutting technology reduces waste.

3.Accuracy control and dimensional stability

Difficulties:

• The tolerances for irregular parts (e.g. electronic components stand ±0.02mm) are strictly required.
• Stamping recoil results in size bias (stainless steel recoil rate can be 8%-12%).

Response strategies:

• Real-time on-line detection system (CCD+laser ranging).
• The surface of the die is modified by the rebound compensation algorithm algorithm.

4.Service life and abrasion resistance of mold

Difficulties:

• The stamping frequency of irregular parts is limited (500000 times the service life of ordinary moulds and more than 2 million times the service life of highly demanding parts).
• The welding process of hard alloy and mold steel is difficult.

Response strategies:

• Surface hardening (e.g. TD coating, PVD coating).
• The abrasion area was repaired by laser cladding.

5.Trial Mode Cost and Efficiency

Difficulties:

• Irregular parts have long test die cycles and cost more than 10000 yuan per piece.
• Traditional methods of trial and error are difficult to locate the root cause of the problem quickly.

Response strategies:

• Digital twin technology simulates the stamping process.
• Rapid prototyping molds (3D printing) shorten the verification cycle.

How does JS company optimize the utilization rate of stamping materials?

1.Intelligent layout design

Technical means:

• Artificial intelligence algorithm is used to arrange stamp metal intelligently and calculate the most optimal nesting scheme automatically.
• Support for uploading STEP/IGES and other formatting files, the system automatically recognizes part contours and generates a layout.

Effect: Material utilization rate increased from 85% of the industry average to over 92% (especially irregular parts). Reduce waste and save approximately 15% to 20% on materials per order.

2.Residual material recycling and reuse system

Technical means:

• Fully automated waste sorting equipment is provided for the real-time classification of recyclable metal debris, such as stamping metal scraps.
• The remaining material is processed into small stamping parts by thermopressing process.

Effect: Meet the standard of sustainable production, a non-ferrous metal recovery rate up to 98%, reduce annual raw material procurement costs of more than 1 million.

3.Modular process, flexible production line

Technical means:

• The complex parts are broken down into standardized submodules (such as holes and bending areas) and batch processing using a uniform molds.
• Seamless switching of different stamp metal parts is achieved through the rapid die conversion system, and the changeover time is no more than 15 minutes.

Effect: 30% shorter lead time and 10% less material loss for multi-variety small order.

4.Material Characteristics and Process Matching Database

Technical means:

• There is a database of more than 50 metallic materials, including parameters such as thickness, ductility and resilience.
• Automatic stamping process parameters are generated to avoid waste due to improper material selection.

Effect: High strength steel (such as 430 stainless steel) stamping qualification rate increased to 99.5%, reducing rework waste.

5.Digital simulation and virtual debugging

Technical means:

• AutoForm software is used to simulate the stamping process of stamp metal and predict defects such as wrinklings and fractures.
• The mold surface is optimized by virtual debugging and the number of die physical tests is reduced.

FAQS

1.What are the advantages of stainless steel stamping parts? ​

Stainless steel stamping parts is corrosion resistant, abrasionresistant and high strength. It is suitable for long-term use in home appliances, medical devices and so on.

2.What are the materials with good ductility?

Including aluminum alloy, copper alloy, brass and pure metals such as gold, silver, aluminum, these materials are easy to shape, suitable for complex stamping parts processing.

3.How does the thickness of metal sheet affect the stamping effect? ​

Thin plate is easy to deform, but the strength is low. It is suitable for precision parts. Thick plates require greater punching force and are prone to burr, making them suitable for structural components. The die clearance and pressure parameters need to be adjusted according to the ductility of the material.

4.Is the dimensional accuracy of metal stamping parts related to the material? ​

Closely related to this, the ductility, bounce and uniformity of the material directly affect the stability of the molding and need to be controlled through mold design and process parameter optimization.
