Safety Basis

1. Material & Protective Coatings
   Aluminium Die casting cookware is typically coated with PTFE (Teflon) or undergoes anodized treatment, which prevents aluminum from leaching into food. For example, anodized aluminum forms a dense oxide layer that blocks direct contact between the metal and food. Even if minimal aluminum leaching occurs, it complies with strict standards (e.g., FDA), where the intake (30-50 mg/day for adults) remains far below safety thresholds.
2. Proven Industrial Applications
   Aluminum die-casting is widely used in automotive, medical, and electronics industries for safety-critical components. For instance, high-vacuum die-cast aluminum parts in cars pass crash tests, demonstrating exceptional energy absorption for collision safety.
3. Eco-Friendliness & Recyclability
   Aluminum is 100% recyclable, with recycled production using 5% of the energy required for virgin aluminum. This aligns with environmental standards like ISO 14001.

Potential Risks & Precautions

1. Coating Damage
   Scratched or peeling non-stick coatings on cookware may expose aluminum. Avoid metal utensils or abrasive cleaners, and choose PFOA-free coatings from reputable brands.
2. Special Alloys
   Some alloys (e.g., AlBeCast™ 930/940) contain beryllium, which can release harmful particles. However, these are rarely used in consumer products like cookware.
3. Manufacturing Safety
   Workers in die-casting facilities must wear protective gear (masks, gloves) to avoid inhaling aluminum dust or fumes, but this does not affect end-product safety.

Usage Recommendations

• Cookware Care: Avoid overheating empty pans; clean with soft sponges and mild detergents. Replace items with damaged coatings.
• Industrial Use: Opt for die-cast parts meeting NADCA standards, and apply surface treatments (e.g., electroplating) to enhance corrosion resistance.

Aluminium Die casting products are safe when designed, produced, and used correctly. Their lightweight, corrosion resistance, and strength make them ideal for diverse applications, but proper maintenance and material selection (e.g., avoiding beryllium alloys) are critical. Always follow manufacturer guidelines for optimal safety.

Haichen Professional Aluminum Alloy Die Casting Machine

Haichen Professional Aluminum Die Casting Machines: Technical Analysis

As a leading Chinese manufacturer of high-end die-casting machines with over 20 years of expertise, Haichen specializes in aluminum alloy die-casting equipment renowned for high precision, multi-scenario adaptability, and intelligent control. Widely adopted in automotive, electronics, home appliances, and industrial equipment sectors, Haichen machines excel in advanced applications. Below is a comprehensive breakdown of their technical capabilities, product portfolio, industry solutions, and innovations:

---

I. Core Technologies

1. Dual Closed-Loop Real-Time Control System
   Haichen machines utilize a dual-closed-loop injection system that adjusts pressure and speed in real time, achieving ±0.01mm injection accuracy. For example, in automotive structural parts production, this system reduces porosity defects to <0.5% by ensuring uniform mold filling.
2. Multi-Stage Pressure-Speed Control
   Supports 4-stage injection (slow fill → high-speed mold filling → pressure intensification → solidification), adaptable to alloys with varying fluidity. In aluminum radiator production, this enables injection speeds up to 8m/s with stable pressure (50–127 MPa).
3. High Vacuum & Temperature Synergy
   Equipped with high-vacuum systems (vacuum ≤30 mbar) and digital temperature-controlled furnaces (±3°C precision), eliminating internal porosity. Ideal for critical applications like EV battery housings requiring airtightness.
