HJF118-F5 Automatic Horizontal Injection Molding | RFQ Sourcing Details

The HJF118-F5 is an automatic, computerized horizontal injection molding machine presented for producing plastic rings from thermoplastics. Its mechanical clamping unit provides 1,180 kN of clamping force, a 340 mm opening stroke, and 370 × 370 mm tie-bar spacing.

Listed mold dimensions range from 150 mm minimum mold height to 400 mm maximum mold height. Three screw configurations are specified. Available screw diameters are 35, 38, and 40 mm, with theoretical shot volumes of 154, 181, and 201 cm³. Corresponding listed polystyrene shot weights are 141, 165, and 183 g.

Injection rates are 80, 95, and 105 g/s, while maximum listed injection pressures are 219, 186, and 167 MPa. Screw speed is adjustable from 0 to 220 r/min.

The clamping section is described with rigid platens, enlarged tie-bar clearance, T-slots and tapped holes, a mechanical safety interlock, and a gear-type hydraulic mold-height adjustment mechanism. The ejection system has a 100 mm stroke, 33 kN force, and five ejector points.

A low-pressure mold-protection system is also listed. The hydraulic system uses pressure-and-flow control through a double proportional compound valve. A servo hydraulic system is listed as optional. The equipment description also identifies independent grease and lubrication-oil circuits.

The installed pump motor is rated at 11 kW, heating power at 6.5 kW, maximum pump pressure at 16 MPa, and oil tank capacity at 210 L. The control system includes an 8.4-inch, 800 × 600 display, USB 2.0 and 100BASE-T Ethernet ports, and storage for 120 process-parameter sets.

Injection-end and temperature tracking curves, parameter recording, and dynamic warning displays are listed. The source also states that interface languages and the electrical system can be configured when specified with the order. The machine measures 4.2 × 1.25 × 1.8 m and weighs 3.5 tonnes.

CE and ISO 9001:2008 certifications are listed in the supplied specifications. A standard export package is specified. Buyer confirmation before ordering: Ask the seller to identify the correct screw configuration for the intended resin, part weight, mold, and cycle requirements.

Confirm whether the offered machine includes the optional servo hydraulic system and which stated servo performance claims apply to the final configuration.

Buyers should also verify mold dimensions, nozzle and locating details, ejector layout, utility requirements, voltage, frequency, phase, cooling demand, control language, included spare parts, installation arrangements, current certification documents, warranty scope, and the final acceptance-test procedure.

Suitability for a particular ring design or production target should be established through mold and process review rather than inferred from the general machine description.
