Customized production lines
Tools, dies and accessories
At the same time, Yinfeng expanded its international market through equipment delivery, overseas installation, operator training, remote programming assistance and customized machine projects.
Public company materials state that Yinfeng’s equipment supports customers in more than 30 countries and regions.
With growing demand for large spring machines and customized automation projects, Yinfeng continued upgrading its manufacturing infrastructure.
The production base developed functions covering:
Precision CNC machining
Machine-frame assembly
Large equipment assembly
Electrical control integration
Machine commissioning
Customer sample production
Finished-machine testing
Spare parts storage
Export packaging and shipment preparation
The use of large assembly areas, lifting equipment and organized production zones strengthened Yinfeng’s ability to manufacture large camless spring machines, heavy-duty spring coiling equipment and customized wire forming lines.
The exact construction year and total factory area should be added after confirmation from Yinfeng’s internal records.
Between 2021 and 2023, Yinfeng expanded its production capabilities into large-wire-diameter spring manufacturing.
The company developed larger camless spring forming machines, heavy-duty compression spring coiling machines and reinforced wire bending equipment.
These machines were designed for products such as:
Heavy-duty torsion springs
Large double torsion springs
Agricultural tine springs
Large extension springs
Automotive seat torsion springs
Heavy compression springs
Railway springs
Mining equipment springs
Construction wire components
Large industrial wire forms
The development of heavy-duty equipment enabled Yinfeng to serve customers in automotive manufacturing, agricultural machinery, railway equipment, mining machinery, construction machinery and other demanding industrial sectors.
The current product range includes large compression spring machines capable of processing wire diameters up to approximately 16mm, together with large wire bending and forming equipment.
As customer production requirements became more diverse, Yinfeng expanded beyond standard spring machines.
The company developed machinery and technical solutions for:
Automotive seat springs
Automotive seat frame components
Agricultural tine springs
Furniture wire parts
Industrial hooks
Wire brackets
Shopping cart components
Wire baskets
Display racks
Construction wire components
Complex 2D and 3D wire forms
This stage marked Yinfeng’s transition from a standard equipment supplier into an application-oriented production solution provider.
Machine selection, tooling and forming processes could be adapted according to customer drawings, wire materials, product structures and production targets.
Yinfeng’s current product portfolio includes wire forming machines, CNC spring machines, compression spring machines, wire bending machines, camless machines and related equipment.
As Yinfeng expanded into overseas markets, the company placed greater emphasis on machine safety, electrical standards and export compliance.
Equipment safety and control functions were gradually improved to include:
Emergency stop systems
Electrical overload protection
Protective enclosures
Abnormal-operation monitoring
Product-quality detection
Automatic shutdown functions
Safe electrical cabinet design
Operating and maintenance documentation
Public Yinfeng materials state that its equipment has obtained CE certification and meets relevant international requirements.
This certification helps support machine exports and gives international customers greater confidence in equipment safety, manufacturing quality and operational reliability.
With the expansion of its product range and international business, Yinfeng strengthened its quality management system.
Quality control procedures were established across the equipment manufacturing process, including:
Incoming material inspection
Machined-component dimensional inspection
Electrical component verification
Servo motor and drive testing
Mechanical assembly inspection
CNC system testing
Axis movement and synchronization testing
Customer spring sample trials
Finished-machine performance testing
Safety inspection before shipment
Yinfeng’s public company materials state that its manufacturing and equipment systems are supported by ISO 9001-related certification.
The quality management system helps standardize manufacturing processes and supports continuous improvement in machine stability, forming accuracy and delivery quality.
As Yinfeng’s product range expanded, the company continued improving the organization of its production facilities.
Key manufacturing processes were gradually divided into more specialized production areas, including:
CNC machining workshop
Parts inspection area
Mechanical assembly workshop
Electrical control cabinet assembly
Equipment commissioning area
Spring sample testing area
Finished-machine testing workshop
Spare parts and tooling warehouse
This specialized production structure helped improve component consistency, assembly efficiency and equipment testing standards.
It also provided a stronger manufacturing foundation for multi-axis camless machines, large compression spring machines and customized wire forming equipment.
Between 2015 and 2019, Yinfeng increased its investment in CNC camless spring forming technology.
Unlike conventional cam-driven spring machines, camless spring machines use multiple independently controlled servo axes.
This machine structure reduces dependence on traditional cams and rocker arms, allowing spring manufacturers to achieve:
Faster machine setup
More flexible forming movements
Easier product changeover
Higher forming accuracy
More complex spring geometries
Greater control over spring arms and end shapes
Yinfeng gradually developed camless spring machines for different wire diameter ranges and spring products, including:
Precision springs
Automotive springs
Agricultural tine springs
Heavy-duty torsion springs
Double torsion springs
Extension springs
Custom-shaped wire springs
This technical direction became one of the most important parts of Yinfeng’s product development.
Following the company’s upgrade to Zhejiang Yinfeng Automation Technology Co., Ltd., Yinfeng continued investing in production facilities and manufacturing capacity.
The manufacturing base was gradually improved to support the development and production of:
CNC spring machines
Camless spring forming machines
Compression spring coiling machines
Wire forming machines
Customized automation equipment
The production system included dedicated functions for CNC parts machining, machine-frame processing, mechanical assembly, electrical assembly, equipment commissioning, spring sample production and finished-machine inspection.
The expansion of manufacturing capacity enabled Yinfeng to improve production organization, strengthen quality control and support larger and more complex equipment projects.
Because the exact factory expansion year and construction area have not yet been verified through internal company records, the website should present this as a development stage rather than claim a specific construction date.
On August 13, 2015, the company was officially renamed Zhejiang Yinfeng Automation Technology Co., Ltd.
The new company name reflected the expansion of Yinfeng’s business from traditional spring equipment manufacturing into:
CNC automation
Multi-axis servo control
Wire forming technology
Industrial automation equipment
Customized spring production solutions
Intelligent machine systems
From this stage onward, Yinfeng increasingly focused on flexible production, independently controlled servo axes, CNC programming and customized machine configurations.
The company also expanded its capabilities in software development, electrical control, production monitoring and industrial automation integration.
