In the field of packaging industry manufacturing and molding, KRMOLD designs and manufactures injection molds for the packaging industry by analyzing the uses and characteristics of different packaging products, helping customers in the packaging industry manufacturing field to improve the efficiency of injection molding and the lightweight requirements of packaging products. Packaging injection molds quickly manufacture high-precision, large-volume packaging containers or functional components by injecting molten plastic into the mold cavity, and are widely used in packaging production in the food, daily chemical, pharmaceutical and other industries. Typical injection mold cases include bottle cap injection molds, beverage preform injection molds, and cosmetic container injection molds.
Design features of KRMODL in the field of packaging industry injection molds:
1. High-cavity mold design
Generally speaking, high production is a significant production demand in the packaging industry manufacturing field. When producing packaging industry injection molds, KRMODL will focus on high-cavity design to increase the output of packaging industry products and reduce unit costs. The design of high-cavity injection molds needs to ensure that the melt in each cavity is evenly distributed. KRMOLD uses a hot runner balanced gating system to avoid product weight differences. Typical case: Bottle cap injection mold adopts multi-cavity mold design to achieve 128 injection molding efficiency.
2. Precision gate design
KRMOLD packaging industry injection mold adopts precision mold gate design. Common gates include pin gate to meet the injection molding needs of small packaging products, valve hot runner gate to achieve high-precision packaging industry product injection molding to prevent flow marks, and side gate mold design is suitable for square and special-shaped containers. When designing the injection mold, it is necessary to ensure that the gate position is uniform to prevent warping and deformation. Generally speaking, injection molds in the micro-packaging industry use small diameter gates to reduce residual marks and improve aesthetics.
3. Rapid cooling system of injection molds
In order to achieve the production needs of large-scale injection molding, the injection molds in the packaging industry need to optimize the cooling system of the injection mold in addition to the design of multi-cavity molds. The cooling time accounts for 70%~80% of the entire injection cycle, so optimizing the cooling system can greatly improve production efficiency. Generally speaking, the direction of injection mold design optimization includes water cooling (Water Cooling) for thin-walled products, high thermal conductivity materials (such as beryllium copper inserts) for local high heat areas, such as the threads of bottle caps. Gas Cooling (Gas Cooling): Applicable to products with special shapes to reduce the problem of uneven cooling.
