The Haijing 138-ton servo injection machine belongs to the Special Injection Molding Machine Series. Developed exclusively for high-precision medical consumable molding scenarios, it serves as a high-performance Injection Molding Machine widely applied in the mass production of syringes, infusion components, medical protective housings, laboratory supplies, disposable medical accessories and various medical plastic products. It has become the core molding equipment for standardized medical plastic production workshops.
Positioned as a professional Servo Energy-saving Injection Molding Machine, this model is equipped with a mature closed-loop servo power control system, achieving independent precise regulation of clamping and injection movements. Compared with traditional fixed-pump machines, it greatly reduces overall energy consumption, lowers operational temperature rise, and extends the service life of hydraulic oil. Its low-heat operating feature effectively reduces air-conditioning load in cleanrooms. With stable low-oil-pressure pulse output, the machine maintains consistent molding precision during long-term continuous operation, fully adapting to the three-shift uninterrupted production rhythm of modern medical factories.
Featuring high-rigid clamping structure and excellent template parallelism control, the equipment ensures uniform clamping force distribution. When matched with high-precision Plastic Mold, it effectively eliminates common defects such as flash and short shot, guaranteeing ultra-consistent dimensional tolerance for every medical plastic part.
Medical-grade plastic manufacturing demands extremely strict standards for raw material cleanliness and molding stability. A single host device cannot fully meet standardized production requirements. Therefore, we provide complete Plastic Machinery turnkey solutions, supporting full-line configuration of professional Plastic Auxiliary Equipment.
In the raw material pretreatment stage, the supporting Drying Machine precisely controls drying temperature to remove internal moisture from plastic pellets, completely eliminating bubbles and silver streaks on finished products. The Autoloader Machine realizes fully enclosed pipeline material conveying, minimizing manual contact and greatly reducing the risk of impurity contamination. During formal molding production, the matched Mold Temperature Controller precisely stabilizes mold temperature, ensuring uniform melt cooling speed and significantly improving the surface finish, structural stability and mechanical performance of medical products. All matched Auxiliary machine units operate synchronously with the main unit, forming a fully closed and clean automated molding process, effectively reducing quality risks caused by manual intervention.
The HJ138S machine boasts powerful platform scalability. Based on the same mature technical system, we support customized professional molding equipment, including the Special Injection Molding Machine For PET Materials, which is specially designed for high-speed production of PET medical packaging and PET preforms.
The overall structural design fully conforms to cleanroom production specifications. Neat body layout and standardized pipeline arrangement facilitate daily cleaning and disinfection in medical workshops. The intuitive human-machine interface supports one-click calling of multiple stored medical product molding formulas, greatly improving mold change efficiency and production flexibility for multi-specification medical parts.
As an experienced manufacturer of professional plastic molding equipment, Haijing provides far more than a standard Injection Molding Machine. We focus deeply on the actual pain points of the medical plastics industry, providing integrated technical support covering main units, molds and full-set auxiliary equipment. From equipment installation, commissioning and operator technical training to long-term after-sales maintenance, we deliver full-process professional services, helping medical manufacturing enterprises stably produce high-quality, high-precision and highly consistent medical plastic products.
