Product Descriptioninjection molding machineZhangjiaGang City BEST Machinery Co., LTD is located in a beautiful development zone in Tanggiao, ZhangjiagangCity, Jiangsu Province, China.Company is very professional in research, development, manufacturing of all kinds plastic machinery and moulds, withmore than 2,000 milion fixed assets, during the past 10 years, we always force our energy into new areas of plasticpackaging machinery, to update the technology, to learn advanced experience, to confirm new theory and new designwe are forming a unique competitive advantage of our owns.The machcines from our company carry good quality and effective after-sales service, upon the domestic market, wehotly export machines to Russia, South Africa, Vietnam, Ethiopia, Saudi Arabia, Malaysia, Canada, Algeria, Uzbekistanand many other countries, create good sales performance and well feedback, all to strenathen our position in this field.SpecificationApplicationsEveryday items: Small plastic products like toothbrush handles, combs, and bottle capsIndustrial parts: Complex components like car bumpers, dashboards, and electronic product housings and buttonsCreative items: Toys, decorative items, and industrial models, suitable for mass production due to their stability and efficiencyKey ConfigurationsStructural Design: The centerlines of the injection assembly and clamping assembly are concentric or aligned, parallel to the installation floor, ensuring a low center of gravity, stable operation, and easy mold installation.Key Parameters: For example, the 300-ton model features a 450×450mm heating panel, a 300mm stroke, and a four-RT mold opening method, supporting large molds and uniform material plasticization. This configuration balances efficient production with operational flexibility, making it suitable for high-precision, high-volume manufacturing.Key ConfigurationsThe core configuration of the injection molding machine consists of the injection system, clamping system, and precision control:Injection system: Includes screw and barrel assembly (diameter/aspect ratio/compression ratio), injection performance (theoretical volume × 0.75–0.85 correction, pressure 100–243 MPa, multi-stage speed control), and independent nozzle temperature control (±0.1°C);Clamping system: Clamping force (800–24,000 kN), platen size and tie-bar spacing (mold installation space), mold opening stroke (≥ 2 times the product height), and ejector force/stroke;Control technology: Multi-stage injection/holding pressure, servo closed-loop control (shot volume error ≤ ±0.1%), and back pressure adjustment (0.5–2 MPa);Extended functions: Quick mold change system, robot/hot runner interface, and hydraulic overload protection. Key Selection Criteria: Precision parts require high injection pressure (>200MPa) and temperature control accuracy (±0.1°C). Large parts rely on clamping force (>1000T) and high injection volume (>2000cm3). Efficient production changes rely on standardized interfaces (mold change ≤ 3 minutes).Note: Configuration must match product size, material properties (e.g., PVC requires a corrosion-resistant screw), and production capacity requirements (e.g., single mold, multi-cavity cycle time).right elevationleft elevationfront elevationModelBST-4500AScrew Diameter75Shot Size(Theoretical)1680Shot Weight1512Injection Pressure152Injection Rate378Screw L/D Ratio20.6Screw Speed0-180Nozzle Diameter20Clamp Tonnage4500Toggle Stroke700Mould Thickness280-710Space Between Tie-bars720X720Ejector Stroke160Ejector Tonnage80Ejector Number13Hole Diameter160Heat Power20.5Max.
