Product Picture
Production Process
1. Raw Material
We purchase high-quality metal wire and strictly sort it into batches upon arrival, preparing it for subsequent processing.
2. Cold Heading
A cold heading machine processes the raw material into the basic shape of the fastener.
3. Thread Rolling
Next, threading, also known as threading, is performed to ensure the screw or bolt has a standard, clear profile.
4. Automatic Lathe Processing
Fully automatic lathes are used to further refine parts, including chamfering, turning, and slotting, to enhance dimensional accuracy.
5. Benchtop and CNC Lathe Finishing
For complex or customized fasteners, we use benchtop lathes and CNC machines for further processing to ensure they meet specific customer requirements.
6. Quality Inspection
All products undergo rigorous manual and automated inspections to eliminate defective items and ensure that every shipment meets customer standards.
7. Functional Testing
Some products undergo specialized testing equipment to verify key indicators such as hardness, thread accuracy, and external dimensions.
8. Packaging and Shipping
Products are sorted, packaged, labeled, and boxed automatically or manually, and then neatly stacked in the warehouse for shipment.
Surface Treatment
Offer a variety of surface treatments for our screws to meet different needs and environmental conditions. Such as zinc plating, nickel plating, hot-dip galvanizing, anodizing, zinc nickel alloy, dacromet coating, phosphating, etc.
Custom Service
1. Custom Sizes and Specifications
Shaft lengths, diameters, and tolerances can be customized to your requirements, ensuring a perfect fit within the machine assembly.
Non-standard sizes are available, including extra-long or extra-short shafts.
Precise control of diameter and coaxiality ensures smooth rotation with minimal vibration.
2. Custom Materials
A variety of stainless steel materials are available: 304, 316, 420, 430, 440C, and more.
Special materials can be selected upon request for high-temperature, wear-resistant, or food-grade applications.
Materials can be customized based on strength, hardness, or corrosion resistance.
3. Surface Treatment and Appearance
Polishing/Mirror Finish – Reduces friction and enhances aesthetics
Electroplating/Chrome Plating – Increases wear resistance and corrosion resistance
Blackening/Passivation – Enhances rust resistance
Other Custom Coatings – Processed to customer specifications
Surface roughness, coating thickness, and hardness can be customized.
4. Custom Processing and Functionality
Secondary Processing: Grooves, keyways, threads, shoulders, or tapers, etc. Heat treatment processes: Quenching, tempering, and quenching and tempering to adjust hardness.
Custom spring-loaded, hollow, or precision-ground shafts are available to meet specific mechanical requirements.
High-precision machining meets high-performance industrial requirements.
5. Packaging and Branding
Customized packaging is available for bulk orders or retail sales.
Laser marking or logo engraving is supported on shafts.
Protective packaging ensures corrosion and damage prevention during transportation.
6. OEM/ODM Process
Request Submission – Provide drawings, samples, or specifications.
Feasibility Assessment and Quote – Our engineering team will assess feasibility and provide a detailed quote.
Prototype Production – Produce samples for customer testing and confirmation.
Mass Production – After sample confirmation, full-scale production begins with strict quality control.
Inspection and Delivery – Shipments are 100% inspected, with flexible logistics arrangements available based on customer needs.
