600T Vertical Clamp Horizontal Injection Single-Sliding-Platen Four-Pillar Injection Molding Machine (LZ-JS6000D) Supporting Efficient Production of Car Side Door Sound-Insulation Panel

In this project, the customer needed stable mass production of PP sound‑insulation panels while ensuring dimensional accuracy, uniform material filling, and defect-free appearance. Sound‑insulation components typically require sufficient and stable clamping force, strong mold compatibility, stable injection performance, automation capability, and energy‑efficient operation.

Based on the customer’s process requirements and future expansion plans, we providedthe600 tonsvertical‑clamp horizontal‑injection molding machine (LZ‑JS6000Dseries), customized with several machine optimizations.

Key Solution Highlights:

1. Vertical clamp + horizontal injection structure:

Provides high clamping accuracy and stable injection direction, ensuring consistent molding quality for large PP sound‑insulation parts and reducing warpage or deformation.

2. 600‑ton clamping force with reinforced platens:

Ensures part density, thickness stability, and structural reliability, while supporting large automotive molds.

3. 65mm screw (1200g shot weight):

Configured according to the sound‑insulation panel requirements, ensuring sufficient PP plasticizing, uniform filling, no flow lines and reduced defect rate.

4. Single sliding platen:

Naturally compatible with robotic arms, enabling automated demolding and part‑removal, improving cycle time and overall production efficiency.

5. Opening daylight (up to 2000mm):

Accommodates large molds and provides flexibility for future mold replacement.

6. Servo energy‑saving system:

Reduces energy consumption by 30%–40%, enhances operational stability, and is ideal for long‑term automated production.

7.Production Performance (Automated): Cycle time: 75 seconds per shot
