32 Cavity Hot Runner Thin Wall Plastic Tube Injection Mold - Cosmetic Pharmaceutical Packaging Mould

This industrial-grade multi-cavity injection mold is engineered for high-volume manufacturing of transparent plastic tubes, widely used in cosmetic, pharmaceutical, and food packaging industries. The mold features a sophisticated "1x32" cavity layout, allowing manufacturers to produce 32 identical tube preforms simultaneously in a single injection cycle, thereby maximizing production throughput and minimizing unit costs.

Alternative Names & Working Principle:​

Commonly referred to as a "tube mold," "cosmetic tube die," or "multi-cavity extrusion mold," this equipment operates on the principle of precision injection molding. Thermoplastic materials such as PET, PP, or PE are heated to a molten state and injected under high pressure into the mold's cavity. Once cooled and solidified, the mold opens automatically, and the ejection system expels the shaped tubes. The presence of pneumatic components suggests an automated handling or ejection mechanism, enhancing operational speed and consistency.

Material & Craftsmanship:​

Constructed primarily from high-grade aluminum alloy and alloy steel (e.g., P20 or 718H), the mold offers an optimal balance between durability, thermal conductivity, and machining precision. The surfaces of the cavities are polished to a high gloss, ensuring the final plastic tubes exhibit a crystal-clear, scratch-free finish. The metallic silver-gray finish of the mold frame reflects its robust industrial design, while the precisely drilled holes and inserts indicate advanced CNC machining capabilities.

Performance & Features:

· High Production Efficiency:​ The 32-cavity configuration enables rapid mass production, significantly reducing labor and energy costs per unit.

· Precision Engineering:​ Tight tolerances and accurate core-pin alignment ensure uniform wall thickness and consistent dimensional accuracy of the tubes, critical for subsequent capping and sealing processes.

· Advanced Cooling System:​ Strategically placed cooling channels optimize heat dissipation, reducing cycle times and preventing warping or internal stresses in the molded tubes.

· Automated Ejection:​ Integrated pneumatic actuators and orange-colored electrical wiring suggest a semi-automated or fully automated ejection system, minimizing manual intervention and increasing safety.
