Product catalog summary

Overview
This document provides technical specifications and guidelines for Synventive's valve gate hot runner systems, focusing on actuators and accessories. It includes detailed descriptions of components, operational principles, and cooling requirements.

Product Specifications

Valve Gate Nozzle Head: An integral part of the nozzle, suitable for single valve gate nozzles.
Actuators: Available in configurations bolted to the manifold or mounted in the mold plate, requiring cooling for efficiency.
Cooling Units: Necessary for mold temperatures above 80°C, with specific flow rates and pressure limits.
Valve Pin Position Control: Utilizes sensors and switches for precise control.
SynCool® Technology: Enhances cooling efficiency in specific actuator series.

Operational Details

Valve Pin Operation: Operates pneumatically or hydraulically with specified pressure ranges and flow rates.
Cooling Requirements: Essential for performance, with specifications for water flow rate, pressure, and temperature.

Recommendations

Consult Synventive for specific applications and design information.
Ensure proper cooling post-production to prevent overheating.

Technical Data
Includes detailed specifications for actuator models, pressure ranges, flow rates, and cooling requirements. Illustrations are provided for reference.

Technical Specifications
The PNC6018M02-F/-R micro switch is designed without an end position, available in two cooling options, and operates within a safety class of IP67. It supports a switch capacity of 0.1 to 10 A at 250 VAC, with a minimum switch capacity of 1 mA at 4 VDC. The operating temperature range is -40 to +125 °C.

Cooling Recommendations
Actuators should be cooled for at least 15 minutes post-production to prevent overheating.

Actuator Specifications
The PNC6018M series actuators are bolted to the manifold and operate pneumatically, requiring a cooling plate for thermal separation. The valve pin operation is pneumatic with a pressure range of 6 to 12 bar and a flow rate of 12 l/min.

Cooling System
The cooling medium is water with a flow rate of 6 l/min and a temperature range of 30 to 60 °C. Supports up to three actuators in a row on a cooling plate.

Valve Pin Details
Diameter options are Ø 5 mm and Ø 6 mm, with anti-rotation attachment available.

Available Versions
Includes several actuator series with specific features such as standard or strong versions with two pistons.

SynCool® Technology
Provides indirect cooling, allowing the system to be switched off without decomposing hydraulic oil under certain conditions.

Cooling and Thermal Management
Cooling systems are critical for maintaining actuator performance. Recommendations include post-production cooling to protect actuators from heat flow from the manifold.

Valve Pin Operation
Detailed for each actuator type, including operation medium, stroke length, and adjustment methods.

Installation and Maintenance Recommendations
Guidelines for installing and maintaining actuators, emphasizing clean and secure electrical connections.

Technical Data
Specifications for components such as micro switches, including safety class, switch capacity, and temperature range.

Additional Features
Includes valve pin position control systems with flow sensors and display modules.

Specifications
Outlines specifications for PNC6018M01 and PNC6018M02 modules, and the Position Control Display Module (PC-DM-08-01).

Operating Data
For servo valves, the operating pressure is 60 bar with a maximum inlet pressure of 250 bar.

Valve Manifold Configuration
Guidelines for configuring hydraulic and pneumatic valve manifolds.
