Jinchun 3-8 Wire Forming Machine: Precision and Speed for Water Pump Motor Handle Production — Up to 20 Pieces per Minute

In the manufacturing of water pump motor accessories, handle forming accuracy and production speed are crucial to ensure efficient assembly and product reliability. The Jinchun 3-8 wire forming machine, developed by one of the leading small 2D CNC iron wire bending machine manufacturers, provides a fully automated solution for producing 255mm and 305mm motor handles with 11×13mm punching requirements—achieving outputs of 15–20 pieces per minute with consistent precision.

 

Key Features Designed for High-Speed Water Pump Handle Production

Wide Material Compatibility

Whether you’re working with round, flat, or square wires (3–8mm), this wire bender and forming machine adapts to a wide range of water pump handle materials.

Straightening System: 28 Cr12-grade rollers remove curvature before forming

Feeding Rollers: Made of Cr12MOV (58° hardness) for smooth and consistent wire feed

High-Precision Punching & Bending

Servo Punching Module (1.0kW): Achieves ±0.5mm wire feed accuracy with hole placement deviation under 0.1mm for 11×13mm slots

Flexible Bending System: SKD11/51 tooling (58–62° hardness) paired with a 3D gearbox enables ±180° angle adjustments and dimension tolerance within ±0.5mm—perfect for load-bearing handles requiring precise fitting

 

Fully Automated Workflow

This 2D CNC bender integrates feeding → straightening → cutting → punching → bending into one seamless process. A 6-axis control system drives all modules simultaneously. For example, a 30×5mm motor handle is completed in just 3–4 seconds, delivering up to 20 pieces per minute at peak speed.

 

Technical Specifications That Ensure Reliable Mass Production

Power & Speed

Total Servo Power: 7.8kW

4.0kW wire feeding servo
