Dedicated Injection Molding Machine For Edible Oil Bottle Preforms

To address the specific characteristics of edible oil preforms-namely their large neck diameters, extended body lengths, and substantial weight-an eight-point, box-type clamping structure has been adopted. This design enhances the mold plates' resistance to deformation, thereby ensuring that the elongated preforms remain free from bending, eccentricity, or indentation; consequently, the subsequent bottle-blowing process is guaranteed to produce bottles that are neither flattened nor deformed.

Featuring an exclusive extended screw combined with a long injection stroke design, this system delivers a large melt volume and ensures thorough plasticization. It effortlessly meets the single-shot injection requirements for large-capacity oil bottle preforms, effectively preventing issues such as material shortfalls, layering, and prominent weld lines, thereby ensuring more stable molding performance.

This low-shear plasticizing system, optimized specifically for edible oil packaging, features precise temperature control to prevent raw material degradation and carbonization. It ensures that preforms exhibit high transparency, remain free of black spots and odors, and fully comply with food-contact safety standards.

Closed-loop pressure-holding control ensures uniform wall thickness from the bottle neck to the base of the preform, resulting in superior strength, impact resistance, and drop resistance-thereby eliminating the risks of leakage, cracking, and bottle rupture.

Equipped with an absolute-value common-bus servo system, it delivers rapid response, stable output, and low energy consumption. Ideal for continuous 24-hour factory operations, it becomes increasingly cost-effective the more it is used.

Key hydraulic and electrical components feature premium brand configurations; the hydraulic circuitry incorporates enhanced sealing to ensure a low leakage rate and simplify maintenance. This significantly reduces downtime, thereby guaranteeing the stable, high-volume delivery of PET preforms.

It can be integrated with automated solutions-such as multi-cavity oil bottle preform molds, automatic extraction systems, and cooling conveyors-to achieve fully automated, high-efficiency production, thereby reducing labor requirements and enhancing both production capacity and product consistency.
