Technical Specifications Explained
Understanding the technical parameters is essential for selecting the right injection molding machine for specific applications. Injection molding machine manufacturers provide these details to help customers make informed decisions based on their unique production requirements.
Clamping Force
This refers to the force applied to keep the mold closed during injection. Measured in kilonewtons (kN), it must be sufficient to counteract the injection pressure exerted on the mold. Injection molding machine manufacturers offer various clamping forces to accommodate different mold sizes and materials.
Shot Volume
The maximum volume of material that can be injected in one cycle, typically measured in cubic centimeters (cm³) using polystyrene as the standard material. This parameter is crucial for determining the appropriate machine size for producing specific parts, which is why injection molding machine manufacturers provide ranges based on screw diameters.
Injection Pressure
The pressure applied to force molten material into the mold cavity, measured in megapascals (MPa). Different materials require different injection pressures, so injection molding machine manufacturers design their equipment to handle a range of materials from low-density plastics to engineering resins.
Distance Between Tie Bars
The horizontal distance between the machine's tie bars, which determines the maximum mold size that can be accommodated. This is a critical dimension for mold designers and production planners, and injection molding machine manufacturers provide this specification to ensure proper mold compatibility.
Mold Opening Stroke
The maximum distance the moving platen can travel away from the fixed platen, determining the maximum part height that can be removed from the mold. Injection molding machine manufacturers calculate this based on typical part dimensions for each machine class.
Injection Rate
The volume of material that can be injected per second, measured in cubic centimeters per second (cm³/s). This affects how quickly the mold cavity fills and is particularly important for thin-walled parts. Leading injection molding machine manufacturers optimize this parameter for both speed and precision.
