Hebei Speed Torque Transmission Technology Co., Ltd. has been a trusted manufacturer of precision aluminum die cast components since 2017. Specializing in OEM Custom Aluminum Die Casting Auto Machinery Hardware Cast Parts, we combine advanced manufacturing capabilities with rigorous quality control to deliver reliable, cost-effective solutions. Our factory spans 3,000-5,000 square meters, staffed by 101-200 skilled professionals, and we export US$5-10 million annually to markets worldwide including North America, Europe, Southeast Asia, and Oceania. Whether you need a single prototype or high-volume production, our ISO9001-certified facility ensures consistency and performance.
Product Overview
Our aluminum die cast parts are designed specifically for the auto machinery and hardware sectors, offering excellent strength-to-weight ratios, dimensional accuracy, and thermal conductivity. Using high-pressure die casting technology, we produce complex geometries with tight tolerances that reduce secondary machining. The standard alloy options include ADC12, A380, and A383, all known for their corrosion resistance and mechanical properties. Each part can be customized in terms of size, wall thickness, surface finish, and post-casting treatments.
Key Features & Technical Specifications
- Material Grades: ADC12, A380, A383, or tailor-made alloys per customer requirement.
- Process Capability: High-pressure die casting (cold chamber) with shot weights from 0.1 kg to 30 kg.
- Dimensional Tolerance: ISO 8062 CT6-CT8 (tighter tolerances available upon request).
- Surface Treatment: Options include powder coating, chrome plating, anodizing, passivation, and more.
- Secondary Operations: CNC machining, drilling, tapping, deburring, assembly.
- Quality Assurance: 100% inspection of critical dimensions, X-ray/NDT on request.

Frequently Asked Questions (FAQ)
- Q1: What is the minimum order quantity (MOQ) for custom parts?
- A: Our MOQ typically starts at 500 pieces for small components, but it varies based on part complexity and mold cost. We can discuss lower quantities for sampling.
- Q2: How long does the mold making and sample delivery take?
- A: Mold design and fabrication generally take 4-6 weeks; first samples can be shipped within 2-3 weeks after mold completion.
- Q3: Can you provide samples before mass production?
- A: Yes, we offer samples for approval. Sample costs and shipping are quoted separately, refundable upon volume orders.
- Q4: What surface finishes do you offer?
- A: We provide a variety of finishes including polishing, powder coating, anodizing (clear or colored), chrome plating, and more. Custom requirements are welcome.
- Q5: Do you have ISO9001 certification?
- A: Yes, our plant is ISO9001:2015 certified, ensuring consistent quality management from material sourcing to final inspection.
- Q6: How do you control the quality of die cast parts?
- A: We perform first-article inspection, in-process checks (SPC), and final dimensional/visual inspection. Additional tests like X-ray, tensile, or hardness can be arranged.
- Q7: What are the typical lead times for production orders?
- A: After sample approval, mass production usually takes 3-5 weeks depending on quantity and complexity. We offer expedited schedules for urgent orders.
- Q8: Can you handle both simple and complex geometries?
- A: Absolutely. Our high-pressure die casting process can produce complex shapes with thin walls, deep cores, and undercuts, subject to mold design feasibility.
