Key Features Multi-Station Cold Forging Process — Configurations from 2-die 4-blow to 6-die 6-blow perform multiple forming operations within a single cycle, producing finished fasteners from wire rod.
Output Range by Configuration — Verified output specifications range from 40 pcs/min (larger M20 products, 3-die 6-blow ZY3640) to 280 pcs/min (small-diameter fasteners on 7B series formers). See parameter tables above for model-specific figures.
Construction and Duty Cycle — Machine tonnage ranges from 15 tons (ZY2415) to 220 tons (ZY3640) forging power depending on product size.
Variable Speed Control — Adjustable production speed accommodates different wire materials and product specifications; specific speed-range parameters are available per model on request.
Product Range — Supports M3-M20 fasteners with lengths up to 250mm across the full model range listed above.
Die Compatibility — Standard and custom die configurations are available; tooling design is confirmed jointly with the manufacturer based on submitted product drawings.
Application Scenarios Standard screw and bolt production Automotive fastener manufacturing Custom non-standard fastener forming High-strength fastener production Rivet and special cold-formed parts Construction fastener manufacturing FAQ Q1: What is the difference between a 2-die 4-blow and a 3-die 6-blow machine?
A 2-die 4-blow machine performs four forming strikes across two die stations, suited to simpler fastener head shapes. A 3-die 6-blow machine performs six strikes across three stations, supporting more complex geometries, longer product lengths, and finer material flow control. In general, more die stations and blows support more complex head/shank profiles.
Q2: What materials can be processed with cold heading machines?
Typical materials include low-carbon steel, medium-carbon steel, alloy steel, stainless steel, brass, copper, and aluminum wire rod. Material grade selection depends on the target fastener's mechanical property requirements — our team can confirm compatibility per your specification.
Q3: What is the typical production capacity of these machines?
Based on the model range above: 1-die 2-blow machines run 90-220 pcs/min; 2-die 4-blow machines run 55-80 pcs/min; 3-die 6-blow machines run 40-80 pcs/min; 7B series high-speed formers reach up to 280 pcs/min. Smaller-diameter products run at higher speeds than larger ones.
Q4: How do I choose the right configuration for my product?
Configuration choice depends on product complexity, length, diameter, and required output rate. Simple screws often need only 2-die 4-blow; parts with head undercuts, multiple diameter steps, or longer shanks typically require 3-die 6-blow or higher. Send your product drawing and target volume for a specific recommendation.
Q5: What is included in the machine delivery?
Standard delivery includes the main machine, main motor, electrical control panel, instruction manual, and basic tooling. Special tooling, wire feeding equipment, and auxiliary devices are quoted separately based on product requirements.
Q6: Is training and technical support available after delivery?
Installation guidance, operator training, and technical support are coordinated through SourcingProChina with the manufacturing partner. Specific service scope (remote vs. on-site) depends on the order and destination — confirm details during quotation.
Q7: What is the typical tooling life for cold heading dies?
Tooling life depends on material hardness, production volume, and maintenance schedule. Carbide dies are commonly rated for millions of cycles under normal operating conditions; exact figures vary by die material grade and application. Product-specific tooling life estimates: [需补充具体数据]
