Multi Station Cold Forming Machine for Self Drilling Screws

YWC Multi Station Cold Forming Machine for Self Drilling Screws is an industrial-grade progressive cold forging equipment that integrates wire blank upsetting, screw head forming, taper shaping, and drill point pre-forming into one continuous process---replacing 3--5 traditional single-station machines. Designed for 6#--14# self-drilling screws in carbon steel, stainless steel, and alloy steel, it solves common pain points of conventional equipment: repeated material transfer, low precision, high defect rates, and inefficiency. As the front-end core equipment for standardized, large-scale self-drilling screw production lines, it seamlessly feeds downstream thread rolling, heat treatment, and electroplating processes. Ideal for manufacturers building new plants, expanding capacity, or upgrading from single-station to integrated production.

Core Product Definition & Main Purpose

Core Usage 1: Integral Blank Forming for Standard Self Drilling Screws

This equipment serves as the core supporting device for batch production of standard DIN7504 self-drilling screws, the most widely used fasteners in the construction industry. It realizes fully automatic integrated processing including raw wire feeding, fixed-length cutting, screw head upsetting, pre-forging shaping, drill tail taper forming and precision finishing via multi-station progressive circulation. The cold-formed screw blanks feature uniform metal density, no internal structural cracks, stable and consistent drill tail specifications, fully complying with international industry standards. The finished blanks can be directly matched with subsequent thread rolling, heat treatment and electroplating processes, perfectly adapting to batch standardized production of 6#--14# conventional self-drilling screws.

Core Usage 2: Precision Forming for High-Strength Drill Tail Screws

Aiming at high-standard production demands of heavy-duty engineering and steel structure industries, this multi-station cold forming machine supports precision forming of high-performance self-drilling screws. Adopting multi-layer progressive cold extrusion process, it can process high-hardness carbon steel, stainless steel and alloy steel raw materials stably. It is professionally used for manufacturing high-tensile and high-strength self-drilling screws with strict mechanical property requirements. The formed drill tail features high hardness, strong penetration and impact resistance, effectively avoiding fracture and slipping during high-strength drilling construction, meeting the rigorous quality standards of engineering and heavy industry scenarios.

Core Usage 3: Custom Multi-Specification & Special-Shaped Screw Forming

Different from traditional single-station machines with single production specifications, this equipment adopts modular die holder design and flexible quick-change mold structure. It can quickly switch production specifications, and is widely used in customized processing of non-standard self-drilling screws, special taper drill tail screws, thickened screw head drill tail screws and unequal-diameter special-shaped drill tail fasteners. It perfectly meets the differentiated and personalized production needs of special engineering projects, special equipment supporting fasteners and customized fastener manufacturers, with strong product compatibility and production flexibility.

Core Usage 4: Front-End Core Processing for Full Screw Production Line

As the core front-end forming equipment of the full-automatic self-drilling screw production line, this Multi Station Cold Forming Machine for Self Drilling Screws can be seamlessly connected with downstream equipment including drill point finishing machines, thread rolling machines, heat treatment furnaces and electroplating surface treatment production lines. It realizes full-process automatic production from raw steel wire processing, screw blank forming to finished screw products, greatly reducing manual intervention and production links. It is the key equipment for fastener factories to build standardized, intelligent and large-scale automated production lines.

Frequently Asked Questions

Q1: What is the difference between a multi-station cold forming machine and a single-station forming machine?

A: A single-station machine completes only one forming step per cycle, requiring multiple machines and manual transfers between steps. Our multi-station machine integrates 4--6 processes (upsetting, head forming, taper shaping, drill point pre-forming, finishing) into one continuous cycle, replacing 3--5 single-station machines and eliminating repeated material handling for higher precision and efficiency.

Q2: What screw specifications can this machine produce?

A: The machine supports 6#--14# self-drilling screws. Customized tooling is available for non-standard sizes upon request.

Q3: What materials can Multi Station Cold Forming Machine for Self Drilling Screws process?

A: It handles carbon steel, stainless steel, and alloy steel, making it suitable for standard construction fasteners as well as high-strength industrial-grade screws.

Q4: How many stations does the machine have?

A: The standard configuration includes 4--6 stations covering wire feeding/cutting, pre-upsetting, head forming, taper pre-forming, drill point precision forming, and automatic discharging. Station count can be customized based on your product requirements.

Q5: Can this machine produce non-standard or special-shaped self-drilling screws?

A: Yes. The modular die holder and quick-change mold structure allow fast specification switching, supporting non-standard tapers, thickened heads, unequal-diameter shapes, and other custom designs per customer drawings.

Q6: How does this machine improve production efficiency compared to traditional setups?

A: Traditional setups require 3--5 separate machines with manual material transfers between each step. Our multi-station machine completes all steps in one continuous cycle, reducing labor, floor space, and handling errors while increasing overall output and consistency.
