Rotary Table Injection Molding Machine
Product Overview
The Rotary Table Injection Molding Machine integrates a high-precision indexing rotary table with a vertical clamping and injection unit. Engineered for insert molding and overmolding applications, the system features a multi-station configuration (dual or triple stations) that enables simultaneous injection, part extraction, and insert loading.
By overlapping non-productive loading time with the molding cycle, the machine eliminates operator idle time and maximizes Overall Equipment Effectiveness (OEE). Empirical production data indicates that the multi-station parallel setup increases throughput by 30 percent to 50 percent compared to conventional single-station vertical presses. It is standardly deployed in automated production cells for automotive electronics, medical consumables, and precision electrical connectors.

Machine Structure & Configuration
Clamping Unit: Vertical Direct-Pressure Hydraulic
Rotary Table System: Servo-Driven Indexing Mechanism
Injection Unit: Single / Double Sliding Barrel Design
Control Architecture: PLC with Closed-Loop Servo Feedback
Vertical Clamping Unit: Direct-pressure hydraulic clamping cylinder ensures uniform tonnage distribution across the mold parting line, minimizing flash on delicate insert components.
Servo-Driven Rotary Table: Driven by a high-torque AC servo motor coupled with a precision roller gear cam indexer, delivering table positioning repeatability within plus or minus 0.03 mm.
Station Layout: Standard 2-station (180 degrees opposing) or 3-station (120 degrees tripling) configurations allow one station to undergo injection while operators or robots load metal or plastic inserts at the alternate station.
Frame Rigidity: Stress-relieved Q345B structural steel base minimizes mechanical deflection under peak clamping loads, protecting precision alignment of guide pillars.
Engineering Resources Note: Complete 2D and 3D CAD layout drawings, footprint dimensions, and foundation loading schematics are available for download in the Request Center below.
Zero-Interference Safety Logic:
Integrated light curtains and dual-channel safety relays prevent table rotation if the mold is incompletely opened or if an insert is misaligned.
Precision Insert Location:
Accommodates complex electrical terminals, threaded brass inserts, and ceramic components with micro-tolerance seating detectors.
Energy-Efficient Servo Hydraulics:
Equipped with internal gear pumps driven by synchronous servo motors, reducing idle energy consumption by up to 45 percent compared to fixed-displacement pump systems.
Modular Injection Capacity:
Interchangeable screw and barrel diameters allow quick adaptation to engineering plastics including PA66, PBT, LCP, TPU, and PPS.
Operator Ergonomics:
Low working height and unobstructed station access reduce operator fatigue during high-frequency manual loading shifts.

Applications
Automotive Sector:
Relay housings, sensor connectors, terminal blocks, steering wheel insert components, and fuel pump wire harnesses.
Medical Technology:
Surgical instrument handles, diagnostic labware with metallic needles, micro-fluidic connectors, and catheter valve components.
Electrical and Electronics:
SMT-compatible connectors, miniature switches, coil bobbins, and breaker components requiring delicate metal pin integration.
Hardware and Tools:
Hand tool overmolding, insulated pliers grips, and consumer hardware fasteners with embedded threads.
Manufacturing & Quality Control
Machining Precision: Structural clamping plates and mold platens are finish-machined on five-axis CNC boring and milling centers, ensuring parallelism within 0.02 mm per meter.
Heat Treatment: Alloy steel injection screws and barrels undergo nitriding and bimetallic hardening treatments, achieving surface hardness of HV 950 to 1050 for abrasive glass-filled resins.
Hydraulic Assembly Cleanliness: Hydraulic manifolds and piping undergo ultrasonic cleaning and pressure flushing prior to final assembly to prevent valve contamination.
Factory Acceptance Testing (FAT): Every machine undergoes a mandatory 72-hour dry-cycle endurance test followed by a 4-hour thermal stability run under loaded conditions before shipment.
Compliance Standards: Electrical panels conforming to IEC 60204-1 standards; hydraulic systems compliant with ISO 4413 specifications.
OEM & Customization
Automation Integration: Mechanical and electrical interfaces prepared for integration with 6-axis articulated robots, vibratory bowl feeders, and vision inspection systems.
Specialized Platen Configurations: Custom bolt hole patterns, T-slot layouts, and hydraulic core-puller circuits integrated directly into the rotary table.
Control System Adaptation: PLC platforms available based on plant-wide manufacturing execution system (MES) requirements.
Cleanroom Readiness: Optional nickel-plated platens, food-grade hydraulic fluid, and enclosed bellows for ISO Class 7 or Class 8 cleanroom injection environments.
