Slide Table Vertical Injection Moulding Machine

Product Overview

The slide table vertical injection moulding machine is engineered for insert moulding and overmolding applications where manual or automated component loading occurs completely outside the clamping zone. Featuring a reciprocating slide table in single-station shuttle or dual-station transverse configurations, this machine allows operators to place metal inserts or substrates into the lower mold while another cavity is undergoing the injection and cooling cycle. This setup eliminates idle cooling time, directly increasing production output for multi-part assemblies in automotive, electronics, and medical industries.

Machine Structure & Configuration

01/

Clamping Unit: Direct-acting vertical hydraulic clamping system with a rigid four-tie-bar structure, ensuring uniform pressure distribution and minimal platen deflection under high tonnage.

02/

Slide Mechanism: Precision linear guideway coupled with a high-torque hydraulic motor or servo-driven rack-and-pinion drive, maintaining repetitive positioning accuracy within ±0.02 mm.

03/

Injection Unit: PEEK- and PA-compatible barrel and screw assemblies featuring specialized nitrided or bimetallic treatments for superior wear and corrosion resistance when processing engineering plastics.

04/

Hydraulic & Electrical Layout: Modular hydraulic manifold blocks featuring internationally recognized proportional pressure and flow control valves, paired with an industrial-grade PLC controller and a multi-axis color touchscreen interface.

Key Features

Non-Productive Time Reduction:

Operator safety and part loading occur concurrently with the injection cycle, reducing total cycle time by up to 30% compared to standard stationary-table vertical presses.

Precise Insert Locating:

Elimination of angular misalignment through rigid slide locking pins that engage automatically prior to mold closure.

Enhanced Operator Safety:

The loading station is positioned completely clear of the upper mold drop zone, protected by advanced safety light curtains and dual-hand start interlocks.

Multi-Zone Temperature Control:

PID closed-loop barrel temperature controllers with solid-state relay outputs, maintaining thermal stability within ±1°C.

Applications

Automotive Wire Harnesses & Sensors:

Overmolding lead frames, connector pins, and electronic sensor housings using engineering resins such as PBT, PA66, or PP.

Medical Consumables:

Producing multi-material micro-fluidic connectors and elastomer-sealed surgical instrument grips.

Low-Voltage Electrical Components:

Encapsulating copper busbars, switches, and miniature circuit breaker terminals.

Hardware-Plastic Integration:

Embedding threaded brass inserts into consumer appliance housings and structural plastic brackets.

Manufacturing & Quality Control

Bed & Platen Machining:

Machine frames and platens undergo high-temperature annealing to relieve internal welding stresses, followed by precision finishing on large-scale CNC floor boring mills to guarantee platen parallelism within 0.05 mm/m.

Hydraulic Testing:

Every hydraulic circuit undergoes rigorous pressure endurance testing at 1.5 times working pressure to eliminate internal and external leakage risks.

Electrical Inspection:

Control panels are wired strictly according to industrial electrical safety standards, with all safety circuits subjected to comprehensive response timing verification.

Dry Cycle Run-off:

Each press undergoes a continuous dry run test before packaging to monitor slide positioning repeatability and hydraulic oil thermal stability.

OEM & Customization

Table Configurations:

Single slide (1 loading position, 1 molding position), dual shuttle (1 loading position, 2 alternating molding positions), or rotary index tables.

Automation Integration:

Mechanical pick-and-place unloader integration, pneumatic core-pull circuits (up to 4 independent circuits), and standard robot interfaces.

Specialized Plasticizing Units:

Hardened bimetallic screws and cylinders tailored for abrasive engineering plastics containing glass fibers.

Custom Voltage & Compliance:

Electrical configurations tailored to regional industrial power standards and safety directives.

FAQ

Q: How does the slide table design improve production efficiency compared to a fixed-table vertical machine?

A: On a fixed-table machine, the operator must load inserts, close the safety door, wait for clamping, injection, cooling, and mold opening before removing the part. The operator remains idle during the molding cycle. A slide table machine allows the operator to load inserts at the external station while the other station is actively injecting and cooling. This eliminates manual loading dead-time, typically increasing hourly output by 20% to 40% depending on cycle duration.

Q: What prevents positional drift of the slide table over long production runs?

A: The slide mechanism utilizes precision linear guide rails combined with a mechanical tapered pin locking system. Before the upper mold descends, hydraulic locking cylinders force high-tolerance taper pins into hardened bushings on the sliding plate, mechanically locking the station in exact alignment with the clamping centerline and maintaining a repeatability tolerance within ±0.02 mm.

Q: Can this machine handle engineering plastics containing glass fiber reinforcement (e.g., PA66 + 30% GF)?

A: Yes, provided the appropriate plasticizing configuration is specified. Standard nitrided screws will wear rapidly under abrasive glass-filled resins. We supply optional wear-resistant bimetallic screws and powder-metallurgy barrels or surface-hardened alloy coatings specifically rated for abrasive engineering thermoplastics.

Q: What are the electrical and pneumatic utility requirements for an 85-ton slide table model (VMS-85SL)?

A: The VMS-85SL typically requires a 3-phase industrial power supply with a total installed motor power of 11 kW. Pneumatic supply requires a clean, dry air source at 0.6 - 0.8 MPa with a flow rate of approximately 300 L/min to drive core pulls, safety gates, and blow-off circuits.

Q: How do you ensure mold protection if an insert is misaligned or fails to seat properly?

A: The machine utilizes a low-pressure mold protection function. During mold closure, if the clamping pressure exceeds a pre-set threshold before the low-pressure zone is fully cleared—indicating an obstruction or improperly seated insert—the programmable controller immediately reverses the clamping motion and triggers an alarm, preventing damage to the mold cavities.

Q: What is the standard warranty and how are replacement parts and technical support handled internationally?

A: We provide a 12-month standard warranty covering core structural and hydraulic components, excluding normal wear parts such as nozzles and heater bands. Critical electrical and hydraulic components utilize globally recognized industrial brands, allowing convenient local sourcing of replacement parts. For technical support, engineering teams provide remote diagnostic assistance via network-connected modules, with replacement parts dispatched efficiently for standard catalog items.
