What type of process is required for titanium alloy stamping?

Titanium alloy stamping requires hot stamping or hot stamping combined with high-precision CNC machining and special mold technology. The specific reasons are as follows:

1.High temperature plasticity improvement

Titanium alloy have high hardness and resistance to deformation and are prone to cracking when pressed at room temperature. By heating the material to 600-850℃ (hot stamping) or 300-500℃ (warm stamping), the plasticity of the material can be greatly improved, forming difficulty reduced and the rebound minimized.

2.Precision CNC auxiliary processing

Combined with JS company's ±0.005mm high-precision CNC equipment, titanium alloy parts can be pressed for precision polishing at the micrometer level to meet stringent tolerance requirements in aerospace, medical, and other fields.

3.Special molds and lubrication technology

Adopt high temperature resistant mold materials(such as tungsten steel or ceramic coated mold), combine nitrogen or graphite lubricants, prevent mold wear and titanium alloy bond, prolong mold life.

4.Surface treatment matching

After stamping, titanium alloys needs to be anodized, sandblasted or chemically passivated to improve its corrosion resistance and appearance. It is also an extension JS company's material processing technology.

How to deal with zero gravity environment in space metal stamping? ​

1.Material fixation technology in microgravity environment

Electromagnetic adsorption and vacuum clamping are used to overcome the limitation of traditional mechanical fixation.JS's automation system adjusts the clamping force in real time, ensuring the metal retains a positioning accuracy of 0.02mm even in weightlessness. The tolerance control of the numerical control equipment reaches ±0.005mm, which satisfies the strict requirement for the precision of spacecraft docking mechanisms.

2.Intelligent flow reconstruction

Through the cooperative operation of industrial robot clusters, JS detects micro-scale displacement by gravity-free compensation algorithm and realizes automatic adjustment of stamping parameters. Its adaptive control system can control the machining error rate to less than 0.3%. The technology has been demonstrated in the production of satellite solar panel supports, with a 40% increase in productivity.

3.Improving adaptability to vacuum-environment processes

The inert gas shielding arc cladding technology used to solve the problem of metal oxidation in vacuum. JS laboratory data show that 15μm of dense oxide film is formed on the surface of titanium alloy surface treated by this process.

4.Optimization of lightweight structural design

Based on 3D printing additive manufacturing technology, JS can achieve integrated topology optimized structures. A case study of a certain type of rocket fuel nozzle shows that through lattice structure design, the weight is reduced by 45%, the pressure bearing capacity reaches 1.8 times that of traditional technology, and the space load requirement is perfectly balanced.

5.Extreme environment simulation verification system

A comprehensive testing platform consisting of vacuum chamber, centrifuges and thermal shock chamber was established, capable of simulating temperature gradients ranging from -180°C to +300°C and 10^-6Pa degree. In vacuum environment, the fatigue life of the validated product increased to more than 5 times the ground condition.

What are the common surface treatment methods for aluminum stamping?

1.Anodizing

• Function: To improve hardness, corrosion resistance and abrasion resistance by electrolysis and forming oxide film on aluminum surface.
• Commonly used in stamping metal forming parts (such as automobile chassis parts, 3C product shells, etc.), the oxide film thickness can reach 15-50μm, which can significantly improve the scratch resistance of the surface.

2.Electroplating

• Function: Coating aluminum surface with metal layers (e.g. nickel, chromium, zinc) to improve conductivity, reflectivity or rust resistance.
• Before plating, the stamp metal needs to be pickled and activated to ensure the adhesion of the coating. nickel plating treatment, for example, can improve the life of plugs and sockets in electronic connector components.

3.Spraying

• Features: Color customization and corrosion protection through electrostatic spraying or fluorocarbon coating.
• Suitable for complex stamping metal surfaces (such as home appliance and lighting fixtures), phosphorylation is required prior to spraying to enhance coating adhesion, which can be 60-120μm film thickness.

4.Chromate Conversion Coating

• Function: To form a passivation film by chromate solution, prevent rust and improve welding performance.
• Used in stamp metal welding (such as car battery trays), the thickness of the film is about 1-3μm, which takes into account environmental protection and corrosion resistance.

5.Polishing/Brushing

• Function: Mechanical or chemical polishing eliminates stamping marks and improves surface smoothness.
• Mirror mirror polishing (Ra ≤0.1μm) meets the requirements of optical devices for stamping metal molds such as aluminum heat sinks.

5.Green manufacturing: Reduce energy energy consumption and waste by 20% using energy-efficient equipment and material recycling systems.

Summary

In the metal stamping industry, the performance of metal stamp is closely related to the accuracy and quality of the final product, and to achieve this goal, it must rely on high-precision pre-processing technology. Through steps such as surface cleaning, deburring, annealing, and surface modification (such as phosphating and lubricating coatings), not only can the ductility of metal materials be significantly improved and the risk of cracking or oxidation during stamping be reduced, but it can also lay a solid foundation for subsequent metal stamping operations.

JS combines high-precision CNC machining technology with environmentally friendly processes, incorporating the concept of sustainable development into the pre-processing stage, ensuring that metal stamping parts can maintain consistency whether they are structurally complex or mass-produced. This full process optimization from material preparation to finished product delivery not only improves production efficiency (reducing project cycle by 15%), but also promotes the industry's transformation towards high efficiency, low consumption, and high added value through technological innovation.

FAQs

1.What is the difference between stamping and casting?

Stamping is a cold machining process in which metal plates is pressed into shape by die. It is high efficiency andprecision and is suitable for thin plate parts. Casting is a thermal process in which molten metal is poured into molds to form complex shapes, but with low precision.

2.How important are molds to stamping?

Mold is the core tool of stamping, which determines the shape, precision and efficiency of parts. Without the die, stamping is impossible, its design directly affects the product pass rate and production cost, is the soul of stamping technology.

3.What should be paid attention to when stamping stainless steel? ​

Stainless steel stamping requires the use of high-hardness die, control stamping speed, stamping with lubricating oil, and annealing in time to eliminate hardening of workpiece, to avoid cracking and excessive mold wear.

4.What thickness of metal is required for stamping automotive parts?

The thickness of the sheet metal commonly used for stamping automobile parts is 0.6-2.5mm. Body coverings (such as car doors) are mainly made of 0.6-1.2mm ordinary steel plates, while structural components (such as collision beams) are made of 1.2-2.5mm high strength steel with balanced strength and molding.
