Precision Aluminum & Zinc Die Casting Parts – Tight Tolerances & Durable Finish

Key Product Highlights

Exceptional Dimensional Precision: Leveraging advanced die casting equipment and process control, we guarantee part tolerances as tight as ±0.1mm.100% Quality Inspection is performed before shipment, ensuring dimensional stability and interchangeability.
Durable Surface Finishes: We offer a wide range of secondary surface treatment options, including Sandblasting, Polishing, Electroplating, Powder Coating, and PVD Coating. These enhancements boost corrosion resistance, wear resistance, and improve aesthetic appeal for both functional and visual requirements.
Premium Material Selection: We utilize high-strength, high-fluidity aluminum alloys (likeADC12, A380) and zinc alloys (like Zinc #3, #5). These materials ensure our castings possess excellent mechanical properties, lightweight characteristics, and long-term reliability.
Efficient Production Capability: We provide a One-Stop Service from mold design and fabrication to die casting, surface treatment, and final assembly. This integrated approach shortens lead times and ensures strict quality control across the entire supply chain.
Comprehensive Quality Assurance: Our quality management system is ISO 9001:2015 certified. Equipped with CMMs, spectrometers, and other precision measuring instruments, we provide a solid foundation for the quality of every part.

Core Material Properties:

Aluminum Alloy ADC12: Offers good castability and mechanical strength, with moderate corrosion resistance. A common choice for automotive components and electronic housings.
Aluminum Alloy A380: Features excellent fluidity and filling capability, ideal for producing complex, thin-walled parts while maintaining high tensile strength.
Zinc Alloy #3 / #5: Possesses high stiffness and hardness, outstanding wear resistance, and can achieve very smooth surface finishes. Often used for high-impact and high-wear components.

Precision Die Casting Process:

Our die casting process begins with precision mold manufacturing. Using high-quality mold steels and scientific cooling channel design, we ensure mold lifespans can exceed500,000 shots. During casting, we strictly control parameters like injection pressure, speed, and temperature to ensure perfect cavity filling, minimizing defects like porosity and shrinkage, resulting in dense internal structures and dimensionally accurate parts.

Quality is at the core of BIE. Our QC spans the entire production workflow:

1.Incoming Material Inspection: All raw metal materials are subjected to composition analysis upon arrival to ensure they meet standards.
2.First-Article Inspection: The first piece from each production run undergoes full-dimensional measurement before batch production proceeds.
3.In-Process Checks: Operators and quality engineers conduct periodic sampling during production to monitor critical dimensions and surface quality.
4.Final Inspection: Before packaging and shipment, every die-cast part undergoes a final rigorous inspection to ensure it meets the specified ±0.1mm tolerance, with detailed inspection reports provided.

BIE's high-precision die castings are widely used in various critical industries due to their reliability and consistency:

Automotive Industry: Engine brackets, transmission housings, sensor casings, chassis structural components, requiring high strength and heat resistance.
Industrial Machinery: Pump bodies, valve components, robotic arm connectors, equipment enclosures, needing stable performance in harsh environments.
Electronics & Electrical: Heat sinks, router/server housings, connector bases, demanding lightweight, high precision, and good EMI shielding.
Communication Equipment: 5G base station antenna housings, filter cavities, with stringent requirements for dimensional accuracy and signal integrity.

Professional Engineering Support: Our engineering team provides Design for Manufacturability (DFM)analysis early in the project to optimize your design for better quality and lower cost.
Flexible Production Models: We support various order types from prototype runs to mass production, adapting our production schedule to your needs.
