Maximize your production capabilities with our rubber injection molding machine designed specifically for the composite insulator industry. This high-precision equipment integrates advanced servo control, efficient vacuum technology, and segmented injection functionality to meet the demanding standards of electrical insulation manufacturing.
Key Features:
Triple Servo-Controlled Hydraulic System
Equipped with three sets of servo motors and a high flow rate of 100L/min, the system ensures stable pressure, energy efficiency, precise motion control, and long-lasting durability.
Comprehensive Heating Plate Assembly
The machine comes with a full thermal structure including upper and lower heating plates, heat insulation layers, and a cold runner plate, enabling uniform temperature distribution and reliable vulcanization.
Independent Vacuuming System with Multi-Stage Exhaust
An advanced vacuuming device allows for individually controlled vacuum cycles and supports multi-stage exhaust programs (optional), helping eliminate air bubbles and improving bonding between rubber and FRP rods.
Fully Adjustable Clamping & Injection Parameters
All critical parameters such as mold clamping/opening pressure, speed, stroke, and injection volume, pressure, speed, and segments are independently controlled to ensure maximum flexibility and precision.
Powerful Double-Cylinder Injection Mechanism
A large oil cylinder with dual injection guarantees strong injection force and stable material output, ideal for HTV silicone rubber used in insulator production.
Precision Clamping Cylinder Design
The composite-structure clamping cylinder provides high clamping force and minimizes product burrs, leading to cleaner, more accurate parts.
Efficient Temperature Control System
The injection barrel is controlled by a mold temperature machine for rapid heating/cooling cycles and precise temperature management, crucial for consistent vulcanization results.
