Melt temperature in injection molding refers to the temperature at which the plastic resin becomes sufficiently fluid for injection into the mold cavity. This temperature is critical for ensuring proper flow, filling, and packing of the mold, directly impacting the quality and characteristics of the final product. Each type of plastic resin has a specific … Read more
The melt cushion in injection molding refers to the small amount of molten plastic that remains in the barrel of the injection molding machine after the injection process has completed. This leftover material ensures that there is a consistent and adequate supply of plastic to compensate for any pressure fluctuations and to maintain a steady … Read more
Jetting in injection molding refers to a defect that occurs when the molten plastic enters the mold cavity in a high-speed, narrow stream, causing it to cool and solidify unevenly. This results in a snake-like pattern on the surface of the molded part, leading to poor aesthetic and mechanical properties. Jetting is often caused by … Read more
Injection blow molding (IBM) is a manufacturing process used to produce hollow plastic parts, such as bottles and containers, in a high-volume and cost-effective manner. This process combines the principles of injection molding and blow molding, making it particularly suitable for creating small, precise, and high-quality hollow objects. Key Stages of Injection Blow Molding Key … Read more
A hot runner system in injection molding is a sophisticated component of the mold that keeps the plastic in a molten state as it travels from the injection molding machine to the mold cavities. This system eliminates the need for runners that solidify and are typically discarded or recycled in a traditional cold runner system. … Read more
Hold time, also known as packing or packing time, in injection molding refers to the period during which pressure is maintained on the molten plastic after the initial injection phase to ensure that the mold cavity is completely filled and the material is packed tightly. This stage is crucial for achieving the desired part dimensions, … Read more
