ARBUEO Injection Molding Machine Specialized for Wide-Mouth Preforms
Food Can & Wide-Mouth Jar Packaging Molding Experts
The production logic for wide-mouth preforms differs fundamentally from that of standard-mouth preforms: they feature larger neck diameters, significant variations in wall thickness, and a susceptibility to deformation and shrinkage, while simultaneously demanding exceptionally high standards for both aesthetic appearance and sealing integrity. Widely utilized in applications such as food jars, honey containers, wide-mouth cosmetic bottles, nut jars, and wide-mouth PET bottles, these preforms impose specific and rigorous requirements on the injection molding machine's clamping rigidity, holding pressure precision, cooling efficiency, and molding stability.
The ARBUEO specialized injection molding machine for wide-mouth preforms-developed by the manufacturer ARBUEO-has undergone extensive optimization specifically for wide-mouth PET preforms, cosmetic preforms, food jars, honey containers, cream jars, and large-capacity packaging preforms. Covering a model range from 170T to 650T, these machines incorporate a reinforced clamping structure, a dedicated holding pressure system for wide-mouth applications, a highly efficient and stable servo system, and a customized plasticizing unit. This configuration ensures perfect compatibility with wide-mouth packaging materials such as PET and PP, effectively resolving common industry pain points-including deformation, neck ovality, uneven wall thickness, and surface defects-to facilitate high-yield, highly stable, and highly efficient mass production.
Product Advantages
Tailored to the specific characteristics of wide-mouth products-namely their large neck diameters and expansive projected areas-this system employs a reinforced box-type clamping structure. This design enhances platen rigidity and ensures a more uniform distribution of force, resulting in stable mold clamping free from off-center loading. Consequently, the wide-mouth bottle necks remain perfectly round-free from ovality, rim warping, or deformation-achieving flawless results in a single, precise operation.
Equipped with precise holding pressure and closed-loop control, the system optimizes injection and holding pressure curves specifically for the thick-walled, large-volume characteristics of wide-mouth preforms. This effectively eliminates defects such as sink marks, shrinkage, short shots, and air bubbles, ensuring both internal and external surface smoothness and uniform wall thickness, thereby significantly boosting the yield rate.
Designed specifically for wide-mouth preforms, the plasticization and temperature control system ensures uniform plasticization, precise temperature regulation, and the absence of carbonization or black spots. The resulting preforms exhibit high transparency and excellent gloss, meeting the stringent aesthetic standards required for high-end food and cosmetic packaging.
By optimizing the cooling oil circuits and temperature control response speed, cooling becomes more uniform and cycle times more stable. When paired with multi-cavity wide-mouth molds, output increases steadily, making the system ideal for high-volume continuous production.
Equipped with a highly efficient, energy-saving servo system, this unit offers power savings, low noise levels, and stable oil temperatures. Key components feature premium brand configurations, resulting in a low failure rate and enabling stable, continuous 24-hour production, thereby lowering overall operating costs.
Supports a quick mold-change mechanism, allowing parameters to be stored and recalled with a single touch. This simplifies product changeovers and lowers the barrier to machine setup, making it ideal for flexible factory production involving multiple specifications, diameters, and production batches.
As a manufacturer that handles its own R&D, production, and direct sales, we eliminate intermediary markups. We provide installation, commissioning, training, a comprehensive machine warranty, and lifetime technical support. For export orders, we offer a complete suite of customs clearance, logistics, and technical services.
