Hydraulic closed loop and motor speed closed loop is realized by control system with the features of high repetition, high linearity, high linearity, high efficiency, high precision, fast response, low rejection rate,low noise, low vibration and long service life, High-rigidity template design with T shot andordinary threaded hole facilitates the mold installtion. Oil filter equipment of high performance and high precision can keep the grease within NAS8. Color control system is adopted.
2. Injection Unit Features
2.1 Injection unit adopts duble-cylinder design, more higher injection pressure, more simpler structure and lower malfunction rate.
2.2 Enlarged-cylinder, adopting two -cylinder design,effectively prevent the adhesive-material leaking phenomenon because of the machine vibration or other reasons when the nozzle is under high-speed operation.
2.3 Adopting graphite bush, improving the wear-resistance, reducing the frequency of using lubrication oil effectively improve the cleanness of the injection part.
2.4 Injection cylinder adopts low-frictional seals, improving the response rate and improve the stability under the complicated processes of injection.
2.5 Bridge-style design, for different L/D plastic parts.

Design is one of the most important facets of the production process because it’s the earliest opportunity to prevent expensive mistakes later on. (Of course, determining whether you have a good idea in the first place is also important, but more on that here.) There are many objectives to design for: function, aesthetics, manufacturability, assembly, etc. The right design is one that accomplishes the required objectives to a satisfactory level, but it may take a lot of creativity to get there. Product design is most often accomplished with computer aided design (CAD) software, like SolidWorks. (Click here for nine pro tips on how to best use SolidWorks in design and engineering.) Proficiency with CAD software is vital because it allows for quicker iterations and more accurate prototyping if necessary.

NINGBO HAIJIANG MACHINERY MANUFACTURING CO.,LTD., situated in Ningbo Yinzhou Investment & Innovation Center, coversa land of more than 50,000M2.It was established in 1992 and now employs a staff of more than 500 people. with CE and ISO9001

Haijiang Company is a hihg-tech enterprise specialized in manufacturing injection molding machine that mainly covers dozens of speci?cations with injection shot of 45-2,0000g and mold clamping force of 400-15,000KN. Based on the marrow of the trade gained and through years' accumulation, the company has made constant innovation to ensure the machine quality.Parts built into the machines of defferent mold locking forces are all processed under specialized management. HJF series injection molding machines are developed by Haijiang Company on the basis of a collection of the advantages assimilated from all world famous brand machines with optimized design realized by CAD/CAM/CAPP where technical problems such as noise of the entire machine and low energy dissipation are removed and thus the design quality of products is secured. The company adopts advanced equipment and technology and applies scientific management. Besides, it has introduced high-precision full automatic CNC machines fitted with imported electric and hydraulic parts, which have tremendously improved the accuracy and steadiness of the whole machine.
