As packaging containers, thin-walled small buckets have strict requirements for transparency, dimensional accuracy, and structural integrity. Through precise temperature control systems, accurate injection control, and stable clamping structures, Lisong injection molding machines provide reliable assurance for the production of high-quality thin-walled products.

 

Precise Temperature Control: The Key to Transparency and Molding Quality

 

      Thin-walled transparent containers are prone to problems such as deformation, visible parting lines, or uneven transparency. The root cause of these defects often lies in insufficiently precise temperature control. Lisong PET-dedicated injection molding machines are equipped with an external high-efficiency cooling system, which can achieve rapid mold heat dissipation, significantly shorten the molding cycle, and at the same time precisely control the mold temperature distribution, effectively suppressing product deformation.

      The precise temperature control system ensures that the melt fills the mold cavity within the optimal temperature range, making the product surface more transparent and the edges and corners more regular. For thin-walled small buckets that need to display their contents, this advantage directly enhances the product's market competitiveness.

 

Precise Injection: Weight Control and Dimensional Consistency

 

      The fifth-generation G series high-speed injection molding machine from Lisong adopts a medium-inertia single-cylinder injection molding mechanism, which is compact in structure, fast in injection startup, and high in injection precision. The oil seal of the injection cylinder has better sealing performance, with no leakage inside the cylinder, making the injection start-stop position control more sensitive and accurate, improving injection precision and product repeatability.

      In actual production, this means that the weight of each thin-walled small bucket is more stable and the wall thickness distribution is more uniform. For packaging containers that need to be stacked for storage, dimensional consistency is directly related to warehousing and transportation efficiency. The precise injection capability of Lisong equipment helps customers achieve refined management from raw materials to finished products.

 

Stable Clamping: Assurance of Structural Integrity

 

      Thin-walled packaging molds usually adopt multi-cavity designs to increase production capacity, which places higher demands on the stability of the clamping system. If clamping is unstable, products are prone to problems such as flash, uneven thickness, or deformation.

      The fifth-generation G series high-speed injection molding machine from Lisong adopts a mechanical direct-pressure central clamping system, which has both the characteristics of a mechanical direct-pressure central clamp and the advantages of uniform and stable hydraulic central clamping. The mold opening stroke is larger, and the mold opening and clamping speeds are fast. The effective mold opening stroke is 20-30% larger than that of other manufacturers. At the same time, it is equipped with a high-speed opening and closing servo proportional valve as standard, providing high mold opening repeatability.

      This design ensures that the mold receives stable support during high-speed production, making the edges of thin-walled small buckets cleaner and the structure more complete, reducing adjustment time and reject rates.
