Product Description Product Name Manual vertical injection molding machineProduct model SMD-342SPower supply voltage 220V 400WHeating temperature 300-degree adjustableTheoretical maximum injection volume per time 0 - 10 grams Plunger diameter 20mmNozzle inner diameter 2mmInjection mode ManualOverall dimensions 30*20*85cmNet weight 20 kg (with the wrench, it weighs 21.5 kg)Key considerations in laboratory selectionMaterial and process matchingEngineering plastics: For high-temperature materials such as PA66 and PC, a machine with a screw compression ratio of ≥ 2.5 should be selected (such as the HLF series from Donghua Machinery) to avoid uneven plasticization.Composite materials: For co-injection molding of PVC/TPE, a dedicated corrosion-resistant screw is required (surface chromium layer thickness ≥ 0.02mm), and the Lien Industrial compatible solution is recommended.Accuracy and repeatabilityThe repeatability accuracy of injection position should be ≤ ±0.05mm (in accordance with the detection standard of Beidai Institute), and a machine with a linear guide rail is recommended (such as the DPB series from Baojie).Mold temperature control accuracy ±1°C (Moirons), and it can be further optimized to ±0.5°C by connecting an external mold temperature machine.
