Specification

Applications

Everyday items: Small plastic products like toothbrush handles, combs, and bottle caps
Industrial parts: Complex components like car bumpers, dashboards, and electronic product housings and buttons
Creative items: Toys, decorative items, and industrial models, suitable for mass production due to their stability and efficiency

Key Configurations

Structural Design: The centerlines of the injection assembly and clamping assembly are concentric or aligned, parallel to the installation floor, ensuring a low center of gravity, stable operation, and easy mold installation.
Key Parameters: For example, the 300-ton model features a 450×450mm heating panel, a 300mm stroke, and a four-RT mold opening method, supporting large molds and uniform material plasticization. This configuration balances efficient production with operational flexibility, making it suitable for high-precision, high-volume manufacturing.

Key Configurations

The core configuration of the injection molding machine consists of the injection system, clamping system, and precision control:

Injection system: Includes screw and barrel assembly (diameter/aspect ratio/compression ratio), injection performance (theoretical volume × 0.75–0.85 correction, pressure 100–243 MPa, multi-stage speed control), and independent nozzle temperature control (±0.1°C);
Clamping system: Clamping force (800–24,000 kN), platen size and tie-bar spacing (mold installation space), mold opening stroke (≥ 2 times the product height), and ejector force/stroke;
Control technology: Multi-stage injection/holding pressure, servo closed-loop control (shot volume error ≤ ±0.1%), and back pressure adjustment (0.5–2 MPa);
Extended functions: Quick mold change system, robot/hot runner interface, and hydraulic overload protection. Key Selection Criteria: Precision parts require high injection pressure (>200MPa) and temperature control accuracy (±0.1°C). Large parts rely on clamping force (>1000T) and high injection volume (>2000cm³). Efficient production changes rely on standardized interfaces (mold change ≤ 3 minutes).

Note: Configuration must match product size, material properties (e.g., PVC requires a corrosion-resistant screw), and production capacity requirements (e.g., single mold, multi-cavity cycle time).
