Automatic Horizontal PET Preform and Plastic Cap | RFQ Sourcing Details

This horizontal injection molding machine is offered for producing PET preforms and plastic caps. The listed configuration combines screw-type plasticizing, hydraulic clamping, automatic operation, and computerized control.

Proportional pressure and flow control allow pressure and speed adjustment, while closed-loop PID control manages temperature. The control interface supports Chinese and English. Machine range and configuration The published BST series includes models from BST-1000A through BST-8500A.

Listed clamping forces extend from 1,000 to 8,500 kN, with A/B shot-weight figures ranging from 128/162 g on the BST-1000A to 4,200/4,350 g on the BST-8500A.

Model-specific heat power, pump power, oil-tank capacity, dimensions, and machine weight are provided in the specification table and should be matched to the intended mold and output requirements. The clamping unit is described as a five-point twin-toggle system.

Hydraulic gear-driven mold-height adjustment is listed as standard, while automatic mold-height adjustment according to the selected clamping force is identified as optional. The injection unit uses balanced double injection cylinders and a high-torque hydraulic motor.

Different screw designs are available for different injection conditions. Controls and safety The equipment is listed with a Siemens PLC, an LCD interface, and electrical components selected for stable operation. Two forms of operating-table safety are described: machine safety and electrical safety.

Buyers should request the exact safety circuit, guarding arrangement, interlock design, and applicable documentation for the ordered configuration.

Procurement points to confirm Before ordering, confirm the exact BST model, resin grade, preform or cap design, mold dimensions, cavity count, required shot weight, cycle target, neck finish, insert requirements, and finished-part tolerances.

The buyer should also verify screw and barrel selection, mold interface, ejector arrangement, cooling demand, compressed-air demand, hydraulic-oil specification, and whether auxiliary equipment is included.

Voltage customization is listed as available, but the required voltage, frequency, phase, installed power, plug or terminal standard, and plant electrical capacity should be documented in the purchase specification.

Confirm the final machine footprint and gross operating weight because these vary substantially by model. Also establish foundation, access, lifting, unloading, and installation requirements. Customization, after-sales service, and a two-year warranty are listed.

Buyers should obtain written confirmation of the customized scope, acceptance criteria, commissioning responsibility, operator training, spare-parts package, service coverage, warranty inclusions and exclusions, and response arrangements.

The equipment is stated to undergo a 24-hour test run before leaving the factory;the test protocol and results should be agreed and recorded for the ordered machine.
