Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Injection Molding Equipment. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The JY-550ST is an automatic, computerized vertical injection molding machine designed for thermoplastic processing. Its vertical injection structure combines hydraulic clamping with screw-type plasticizing.
The stated configuration uses a fixed lower mold and movable upper mold, making the machine suitable for insert-molding processes where components must be positioned in the mold before injection. An ejector is included for finished-product removal. Three screw barrel diameter options are listed: 32, 34, and 42 mm.
Their corresponding stated maximum shot weights are 102, 123, and 176 g, while the listed injection pressures are 1,642, 1,385, and 960 kg/cm². Screw speed is adjustable from 0 to 175 rpm. The machine provides 55 tons of clamping force, a 670 × 480 mm platen, a 200 mm opening stroke, and 1.76 tons of ejector force.
The hydraulic system has a stated maximum pressure of 140 kg/cm², pump output of 40 L/min, and oil reservoir capacity of 150 L. Listed electrical loads include a 7.5 kW/10 HP pump motor, 4.5 kW barrel heater, and 12 kW total power. Cooling-water consumption is stated as 800–1,000 L/hr.
Machine dimensions are 1.85 × 1.2 × 3 m, with a listed machine weight of 3 tons. Supported processed plastics include PP, PC, ABS, PET, PVC, FRPP/PVC, PPR, EVA, and HDPE.
The listed application examples include terminal blocks, household appliances, consumer electronics, power tools, automotive dashboards and parts, medical devices, open containers, connectors, cables, and plugs.
Suitability for any specific part still depends on resin grade, insert design, mold construction, shot requirements, and the selected screw barrel.
Before procurement, buyers should confirm the exact screw diameter and shot specification, the applicable mold-height and opening-distance configuration, electrical supply requirements, cooling-water quality and connection details, hydraulic-oil requirements, mold interfaces, guarding, and installation clearances.
Buyers should also request confirmation that their resin, inserts, mold, cycle target, and finished-part geometry are suitable for the proposed machine configuration. Customization is stated as available, but its scope and effect on the final specification should be documented before ordering.
