Key Features

Description

Shuenn Jaan Machinery Co., Ltd. is a professional injection molding machine manufacturer, offers durable plastic injection machines for the plastic processing industry use. If you are looking for superior plastic injection machine, they are all available from us.


Plastic (toggle inward) injection molding machines are new invented products that have higher standards in performance, more flexibility and more efficiency than traditional. Also, in order to cater in customers' different preferences, CNT Series can be custom-made to fit customers' needs. Below are models of custom-made CNT series built for our previous customers.
 
CNT-A (High Speed Injection Machine):
CNT-A, as with accumulator hydraulic circuit design, the injection speed can reach above 300 mm/sec. By using low speed can improve heavy or thick product's layer to feel smoothly and evenly. Using high speed can produce big amount of thin layer products in a short period of time.
CNT-C (Fully Closed Loop Hydraulic Design Machine) :
This model is high precision, high stability, and low loss. Also, as with closed loop hydraulic design, the injection speed can reach above 500 mm/sec, and response speed is 40 Hz/sec. Moreover, it can always check the variation itself and adjust itself automatically to achieve high precision, good stability and low loss. The machine that with closed loop is always on top series, it is the best choice for precision products such as electronic plastic elements and would always keep the product identical .
CNT-S/SD (High Pressure, High Speed Model) :
A small and precision product is the main trend nowadays. Therefore, CNT-S/SD is designed to reach injection speed above 180 mm/sec, and injection pressure above 3000 kg/cm2 . It is also a very good choice for precision product as electronics plastic elements .
CNT Bakelite:
CNT Bakelite is designed for thermo setting resins and can be customized with some features, such as mold heating system, ventilating system, and mold thermo isolating system .
CNT 3 Loop:
The model such as CNT 3 Loop is designed to perform many motions simultaneously. Charging raw material and opening mold work at the same time. Opening mold and ejecting product work at the same time. This will reduce cycle time and is a very good choice for producing big amount or thin layer with big surface area product .
 
 

 

 
Features

Energy saving, high efficiency and low noise.
CNT Series use Japan YUKEN vane pump with small model using double pumps and big model using multiple pumps. It creates low oil temperature, stability, energy saving, low breakdown, low noise and saves power of about 30%.
Triple safety devices (mechanical, electrical, hydraulical) make sure the safety of operation.
Melt-resin anti-splashing cover.
The machine moving areas are fitted with Japan self-lubricating bushings embedded with solid lubricant.
The machine moving area, some parts are fitted with ball bearings, increasing force area and decreasing friction.
Through computer analysis, successfully invent high efficiency, high accuracy, and robust toggle mechanism. This makes toggle space of clamping unit reduced, longer daylight and mold opening stroke maximized.
Using high response solenoid valves, quick time response.
Using import potentiometer, position calculation is accuracy.
Screw section is alloy steel and nitriding. It’s robust and ductibility is increased.
Tie bars are imported from Japan, the NH48MV special steel accompanied with special screw thread design avoids the breaking of Tie bars.
To avoid the deformation of traditional sliding rods type, we developed sliding plate of carriage with front pulling cylinder, ensuring the parallel between injection carriage and barrel. The screw is never tilted.
Every machine is assembled with special skill and adjustment. The life span is long and is good for mold that will reduce repair.
Japan ES-650 micro-computer controller is easy for amending the programs on the machine which will erase a lot of programming time. It also can be customized for special mold design. Besides, ES-650 has mold temperature control device, it can save the cost for purchasing additional mold temperature controller.

PICTURE EXPLANATION :

High Injection Pressure, High Speed Model
The model is divided into S, SD type, can be equipped with optional accessories such as semi-closed loop, closed loop, compound hydraulic circuit, and accumulator circuit design. The highest injection speed reaches 180 mm /sec, and the highest injection pressure reaches 3000 kg/cm2. It is very suitable for all kinds of plastic injection molding products.


Injection Closed Loop and Semi-Closed Loop Hydraulic Circuit Design
Closed loop hydraulic circuit design is popular in advance countries nowadays. The closed loop response speed reaches 40 HZ/sec. It can make sure the precision of dimension and weight in every molded part.


High Efficiency and Energy-saving Pump
Adopting Japan (YUKEN) double vane hydraulic pump. Saving 30% power and accomplishing low oil temperature, low noise and low breakdown.


Strongest Clamping Unit Structure
CNT-series Clamping Unit adopts robust structure to protect mold during high precision molding procedure. All moving parts use Japanese made self-lubrication bushes. Toggle pin surface stress less than 500 kg/cm2, make sure the service life of toggle system. Tie bars are imported from Japan, the NH48MV special steel accompanied with special screw thread design that avoids the breaking of Tie bars.



Injection Sliding Carriage Design
To avoid the deformation of traditional sliding rods type, we developed sliding carriage with front pulling cylinder, ensuring the parallel between injection carriage and barrel.


High Quality Japanese Micro Computer Controller
Our controller is easy for amending the programs on the machine. It is suitable for special mold design. Besides, ES-650 has mold temperature control device, it can save your cost without purchasing additional mold temperature controller.
