The lamp covers normally have complex shapes, often with deep-cavity, multi-step rotational bodies and sharp corners, which require multi-stage precision deep drawing dies. Yixing Technology have rich experience on this. We don't just manufacture molds; we also provide manufacturing solutions to accelerate your prototyping and reduce your costs.

1.  Multi-stage Precision Deep Drawing die(for high quantity)

    The lamp covers require continuous deep drawing through multiple die sets (typically 4–8 sets), then forming the flat sheet into the required deep-cavity complex shape.
    Die Characteristics: Design the process Step: The deformation amount for each stage must be precisely calculated, balancing material flow to prevent wrinkling and cracking. These considerations must be considered from the beginning of the design.
    High Rigidity mold steel: To avoid elastic deformation during stamping and drawing that affects surface precision, the dies are normally made of extremely high structural rigidity steel
    Design the mold Clearance: The gap between the punch and die must be controlled—uniform and slightly larger than material thickness—to ensure smooth material flow without excessive thinning.

    Balance Wrinkling and Cracking in a Metal Sheet：For deep drawing of metal sheets, flat areas are prone to wrinkling, while sharp corners and step surfaces are prone to cracking. To avoid this, we need to use a reasonable deep drawing process, fill with high-performance deep drawing oils, and add Process Supplement and drawing ribs.

2. Metal spinning for a small quantity

Understanding that tooling costs and lead times are critical, we offer pinning service for lamp covers. This allows us to produce complex parts without the heavy investment in tooling.

·   Cost-Effective Flexibility: Metal spinning can achieve deep-cavity shapes similar to deep drawing, but without the die costs.

·   Fast Turnaround: Go from CAD to physical part in days, not weeks.

Why Choose Yixing Technology?

    Lamp covers often have intricate geometries, like deep cavities, multi-step rotational contours, and sharp corners. These complex shapes demand multi-stage precision deep drawing molds. Yixing Technology has 20+ years of experience and can meet these challenges.

    Whether you need the durability of a multi-stage precision die or the speed of a low cost mold process (metal spinning), Yixing Technology delivers complex, high-precision lamp covers matched to your specific production needs.
