Classical Steel Ball Cold Header: Robust, Compact & Cost-Effective
The classic steel ball cold heading machine has long been a cornerstone of traditional ball manufacturing, renowned for its proven design and mechanical reliability. Ideal for small-to-medium-scale production of bearings, hardware components, and general mechanical parts, this machine balances durability, space efficiency, and affordability, making it a preferred choice for cost-conscious manufacturers or those requiring flexible production capabilities.
Key Features of Our Steel Ball Cold Header
● Robust & Durable Structure
■ Cast iron body and high-strength alloy steel transmission mechanisms ensure exceptional impact resistance and longevity under heavy-duty operation.
■ Modular design simplifies internal components, with critical parts (e.g., cams, linkages) rated for over 10 years of service life.
● Compact & Versatile
■ Occupies only 60-70% of the floor space required by high-speed intelligent models, ideal for workshops with limited space.
■ Supports a wide diameter range (Φ1-Φ22mm), enabling quick product switching via mold replacement.
● Cost-Effective Operation
■ Mechanical drive systems reduce energy consumption and maintenance costs.
■ Standardized components simplify repairs and minimize spare part costs.
● User-Friendly Operation
■ Manual/semi-automatic control with analog gauges and physical buttons-no complex programming required.
■ Short setup time (<30 minutes for mold changes and calibration), lowering technical skill requirements for operators.
● Reliability & Adaptability
■ No sensitive electronics, ensuring stable performance in dusty, oily, or humid workshop environments.
■ Tolerates voltage fluctuations and temperature variations without compromising output quality.

Our company offers seven classic steel ball cold header models: LD-35QFZ, LD-50QFZ, LD-80Z, LD-100Z, LD-130Z, LD-160Z, and JM-220Z (refer to technical specifications for detailed parameters). The LD-35QFZ, LD-50QFZ, LD-160Z, and JM-220Z feature a fully enclosed protective housing with enhanced functionalities:
● Low-noise operation: Multi-layer acoustic insulation reduces noise levels below 75dB
● Oil-splash prevention: Integrated shields contain coolant dispersion
● Aesthetic industrial design: Streamlined sheet metal casing improves workshop cleanliness
● Safety compliance: Perimeter safety door interlock system (CE-certified)
The LD-80Z, LD-100Z, and LD-130Z adopt a semi-open protective structure, delivering distinct advantages:
● Space-efficient footprint: narrower profile for confined production areas
● Process visibility: Observation windows enable real-time monitoring of forming operations
● Maintenance-friendly design: Easy-access panels streamline routine servicing
