FAQ

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

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

Q1: What is the minimum order quantity (MOQ)?

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

Q2: Is the mold opening fee high? Is it cost-effective to order small batches?

A: We use modular mold design to reduce initial costs; support module sharing (only change the mold core). Small batch orders can be diluted by combining molds (one mold with multiple holes), usually ≥500 kg The mold opening fee can be shared, and there is no mold fee for subsequent orders.

Q3: How to choose the 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 (ordinary 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 applicable.

Matt 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 based on your application environment (indoor/outdoor, contact medium, wear resistance requirements, etc.) and appearance requirements.

Q4: Will deep processing cause deformation of the profile? How to control it?

A: Use stress release process + multi-point flexible fixture + layered cutting strategy Triple control:

After extrusion, aging treatment eliminates internal stress

During CNC processing, dynamic compensation deformation

Thin-walled parts use vacuum adsorption clamping

Final deformation ≤0.1mm/m (far exceeding the national standard)

Q5: Can assembly holes be directly processed on the profile surface?

A: Support "extrusion + processing" integrated molding:

Preset process holes: Reserve positioning reference holes during extrusion to improve deep processing accuracy

Feature integration: Embed guide grooves and install bosses during mold design to reduce post-processing

Q6: How to ensure wall thickness uniformity for complex cross-section profiles?

A: Core technology guarantee:

Mold diversion design: Multi-stage welding chamber balances metal flow

Online quenching system: Accurately control the fan water cooling strength to prevent thin wall overburning

Traction machine closed-loop control: Real-time adjustment of tension to eliminate bamboo marks Wall thickness tolerance stable control within ±0.08mm
