Introduction

A specialized straight-line forming system for automotive front panels. The forming platform is propelled by hydraulic units. Dual-side reversal platform cylinders allow the upper mold to pivot up to 90°, while the tooling engagement is controlled through a servo‑motor‑driven locking mechanism. The lower mold features vacuum suction for secure panel hold and accurate forming.

Working & Design

• Straight‑line hydraulic travel: Ensures linear, stable vertical motion of the forming platens.

• Reversal mold capability: Driven by dual cylinders, the upper mold reverses up to 90° to facilitate easy loading/unloading.

• Servo‑motor locking: A closed‑loop servo system offers precision mold locking and unlock cycles.

• Vacuum work-holding: Below-the-mold vacuum suction maintains panel position and integrity during forming.

The automated production sequence includes multiple synchronized steps:

1. Recirculating chain drive continually moves trolleys.

2. Air exhausting clears fixture cavities before mould closing.

3. Fixture tilting, unlocking, and automatic opening prepare for loading.

4. Manual tasks: unloading formed parts, cleaning, applying release agent, and loading new panels.

5. Automatic phases: injection of the panel, mould closing, air connection, positioning fixture, locking fixture, and curing cycle.

6. Recycle: after curing, cycle resets and trolley advances to next station.

This stepwise automation supports both high efficiency and precision production.

Key Features:

• Servo / Converter motor-driven chain system: Offers high precision, torque, and speed control—ideal for synchronized forming lines.

• Multi‑station elliptical layout: Maximizes throughput with continuous trolley progression.

• Dual heating methods: Electric and steam options ensure flexible thermal control.
