Double-shot

Product catalog summary
Overview: The document outlines the features and benefits of an all-electric double-shot injection molding machine designed for two-material molding. This machine enhances design aesthetics and functionality by combining different colors and materials into a single part.
Specifications: The machine offers clamping forces from 290 kN to 4,000 kN, suitable for various applications. It features a toggle clamping system, rotary ejector rod, and high-speed injection capabilities. Key mechanical specifications include ejector stroke, nozzle protrusion, and clearance between tie-bars, with a maximum rod ejection of 97 and a stroke range of 0 to 150.
Technological Features: Proprietary technologies include temperature control piping for the rotary unit, independently turning plasticizing units, and a direct drive system, contributing to stable precision molding and efficient production cycles.
Advantages: The parallel arrangement of injection units saves space and supports applications requiring improved sealing, resistance, and dimensional accuracy. It reduces processing steps and required floor space, enhancing production efficiency.
Molding Processes: The machine supports rotary type, core back type, and laminate molding processes. It is compatible with special resins like Liquid Silicone Rubber (LSR), ensuring stable molding without burrs.
Efficiency and Maintenance: The design allows for shorter setup times with integrated molds and features a temperature control manifold for easy maintenance. Reduced mold rotation time improves productivity.
Applications: Suitable for producing automotive switches, audio parts, and construction materials, the machine is effective for small lot production and cleanroom environments.
Procedures: Instructions are provided for selecting the appropriate ejector unit and screw, with notes on mechanical dimensions and changes in maximum opening stroke and daylight.
Standards and Compliance: Mold mounting diagrams comply with JIS B 6701 standards, ensuring adherence to Japanese specifications.
Recommendations: Recommendations include using specific screw types and dimensions for different configurations and selecting the correct ejector unit for optimal performance.
Key Data from Tables and Diagrams: Ejector rod diameter options are φ30 (Standard) / φ25 (Option). Maximum moving stroke after rotation and daylight dimensions are provided for various configurations. Cooling water jacket specifications include supply and drain details with Rc1/2 FL.+252.
Critical Information: Emphasizes the importance of selecting the correct ejector unit and screw type to ensure proper operation and avoid issues. Safety features include a safety door and upper cover, with specific mounting instructions. Detailed diagrams for mold mounting and ejector rod configurations highlight the need for precise installation and maintenance.

Fine-tune individual control before/after mold rotation Features designed for cycle time reduction Even with two perfectly identical two-material molds, there is actually a difference after rotating the mold. With our double-shot machine, molding inaccuracies of the sort have been improved by making it possible to individually control conditions before and after the rotation. Moreover, because torque is meticulously detected, molds are subjected to less stress, which relieves the worries of damaging expensive molds and allows to extend the maintenance interval. Our double-shot machine Common...

Capability for a wide range of molding processes and special resins Multi-toggle is a mechanism that applies a low clamp force at the start of filling and then increases pressure as filling progresses. It improves gas release, prevents burrs from forming and lessens the frequency of mold cleaning. These benefits are especially appreciated in two-material molding where elastomers are often used. A low clamping force is applied at the start of filling to improve gas release. Clamp force is increased as filling progresses to prevent burrs. Particularly effective measure against elastomer gas Diverse...
