Precision Pressfeed Stamping Line

A precision pressfeed stamping line is a high-speed, automated coil processing system specifically designed for the production of small, intricate metal stamping parts. This cold-forming process utilizes precision dies and high-speed stamping presses to transform sheet metal into finished components with exceptional accuracy and consistency.

Standard System Configuration:

Step 1: Decoiler Straightener

Loading the coil and uncoiling the strip, while straightening removes curvature and internal stress. Ensures a flat, stress-relieved material for precise stamping.

Step 2: High-Precision Servo Feeder
Feeding the leveled strip into the press with ±0.15mm accuracy. Servo-driven with PLC control for programmable feed length and speed, ensuring consistent part quality.

Step 3: High-Speed Press with Progressive Die
Stamping parts through a progressive die that performs multiple operations (blanking, punching, bending) in a single press stroke. Achieves speeds up to 100 strokes per minute for high-volume production.

Step 4: Automatic Collection System
Collecting finished parts and organizing them for downstream operations or packaging.

Main Machine Of Precision Pressfeed Stamping Line

Combo decoiler straightener GL

Coil width: 0-600mm

Coil thickness: 0.3-3.2mm

Pressure Arm optional

The roller is made of solid bearing steel. After heat treatment, hard chrome plating and re-grinding, it has high hardness, good abrasion resistance and long use life.

Can reduce the loop between the coil uncoiling and leveling process, which saves 2-5m space in workshops.

With a remote control handle and automatic electric system, it has excellent operational safety protection.

Coil Servo Feeder RNC/NCF/RF

Stabilized Steel frame construction make the quality of machine more reliable.

High concentricity mechanical structure ensures better coil feeding performance.

Roller hardness comes HRC60-62°, Gear driven upper Roll with anti-backlash features to ensure non-slip.

High-precision drivers by utilizing the capabilities of high-resolution servo motors and servo drive with low inertia, ensures a reliable coil feeding accuracy.

Stamping press APA/APC/APM (35-315Ton)

Type: Mechanical press machine

Tonnage capacity: 35-315ton

Steel welded body, tempering treatment, high rigidity, accuracy and stability, low integrated clearance, small changing in mold height.

Small deviation of dynamic center, the mold life in large scale, small transfiguration for press.

Vertical located crankshaft, compact structure.

The crankshaft undergoes grinding treatment after high frequency quenching.

Progressive die

Progressive die stamping is a process used during metal forming that can create parts for a host of industries. Progressive dies are often utilized in higher-volume production, with their components engineered to function at higher rates of speed.

Customized according to client's drawing of parts.
