FAQ

Q: What challenging aluminum alloy features are you best at processing (such as thin walls, deep cavities, microstructures)?

A: We specialize in ultra-thin walls (<0.8mm) stable processing, large depth-to-diameter ratio (>10:1) precision holes/cavities, and micro-channels/heat dissipation teeth. The success rate and quality are ensured through special tools, process parameter optimization and process monitoring.

Q: What is the minimum order quantity (MOQ)?

A: We offer flexible ordering models. For CNC machining and sheet metal processing, we support small batch prototyping (even single piece) to large batch production. Die casting processing usually requires a certain minimum order quantity. The specific MOQ depends on the complexity of the part, the process requirements and the material. Welcome to consult, we will provide the most cost-effective solution.

Q: For precision parts that require extremely high dimensional stability (such as optical platforms), how do you control processing deformation?

A: We adopt multi-dimensional control:

1) Material pretreatment: Strict stress relief annealing

2) Process design: Adopt symmetrical processing, step-by-step stress release strategy, and use finite element analysis (FEA) to assist in predicting deformation; 3) Clamping and processing: Use low-stress special fixtures, adopt small cutting depth, fast feed, and stable cutting parameters for multiple processes;

3) Process monitoring: Aging or stabilization treatment after key processes, and intermediate measurement compensation.

Q: How to choose surface treatment? Which one is best for my product?

A: The choice of surface treatment depends on your specific needs:

Wear resistance, corrosion resistance, insulation, beautiful coloring: Anodizing (normal or hard) is recommended.

High corrosion resistance, uniform coating, complex shape coverage: Electrophoretic coating (ED) is a good choice.

Rich colors, good protection, cost-effective: Powder spraying is suitable.

Matte texture, cover scratches: Sandblasting or brushing.

Conductivity or electromagnetic shielding is required: Conductive oxidation.

Our engineers can recommend the most suitable surface treatment process for you according to your application environment (indoor/outdoor, contact medium, wear resistance requirements, etc.) and appearance requirements.

Q: What is the processing accuracy?

A: Our precision CNC processing capabilities can usually achieve an accuracy of ±0.05mm or even higher (depending on the part size, structural complexity and specific features). For parts with general requirements, we can also ensure a standard tolerance of ±0.1mm. Please clearly mark the specific accuracy requirements in the drawing, and we will evaluate and confirm the feasibility.

Q: How long does it take from ordering to delivery?

A: Delivery time depends on order complexity, quantity, current production schedule, and whether special surface treatment or heat treatment is required. For small batch proofing, it can usually be completed within 1-2 weeks; small and medium batch production is generally completed within 2-4 weeks; large batch orders require specific evaluation and negotiation of delivery time. We are always committed to providing fast response and reliable delivery while ensuring quality.

Q: How to ensure product quality?

A: We strictly implement the ISO quality management system. The production process includes multiple quality inspection links (IQC, IPQC, FQC/OQC), and key dimensions and form and position tolerances are detected using three-coordinate measuring machines (CMM), two-dimensional imagers and other equipment. For surface treatment, we also test film thickness, hardness, color difference, salt spray resistance, etc. We provide first article inspection report (FAI) and shipment inspection report. Customers are welcome to specify or jointly confirm the inspection standards.
