injection machine


1 The mould closing unit 

The new generation mold locking device and computer emulation optimized parameter makes motions of  the moving plate fast and steady .When combining the box type moving plate ,fixed plate and high rigidity toggle structure ,the characteristic of high strength and anti-fatigue is secured. As compared with similar machine , it owns bigger internal spur between tie bars ,mold space and mold opening storke and may process plastic product of bigger size.

2 Computer controller 

professional injection molding machine controller with software abd hardware of industrial standard is convenient  to expansion and revision of performance. Adopting double CPU control makes high speed.

Variable Displacement Pump


1 Low Noise 

Reasonable hydraulic control structure design, high integration and unipue processing in noise reduction helps machine run smoothly.

2 Oil-saving 

The low oil temperature prolongs the srevice life of sealing elements .Oil cleaning equipment can filter the grease rapidly and effectively to ensure the srevice life of hydradulic elements.

3 Quick Response 

The imported directly and high-response variable displacement pump achieves larger amount of emission by 20% to 25% than fixed pump driven the same motor.

4High Stability

30% to 70% energy saving compared with fixed pump under the equipment volume of work .

5 Water Saving 

With no overflow and heating from variable displacement with fixed pump, 50%-75% water can be saved compared with fixed pump. Oil cleaning equipment is designed to improve the service life of hydraulic oil for 5 year.

Q:On the estimation of injection molding cycle? Twenty
If a trial can be used to test out the stopwatch + wide release time, not the trial production of new software available for calculation, but the structure of a product cycle also depends on the size and thickness of the product, is complex and molding technology to all of these affect the product cycle, your statement is not very clear and it is difficult to give you a more accurate estimate of the cycle, experienced personnel can structure size, thickness, the product was estimated, and more reasonable!
Q:What kind of lubricant does the injection machine use?
The main use of antiwear hydraulic oil, as well as 00-000, extreme pressure grease
Q:Injection molding machine barrel temperature is not very high at normal and low temperature line is very tight no problem
The temperature is directly proportional to the resistance, the temperature, the line resistance, and the temperature of your line!
Q:How much is the ejection rate of injection molding machine?
The amount of ejection is dependent on the mold and the plastic material.First look at the first mock exam after injection, the material handle has no salivation, if any, can be set to shoot back, slowly, starting from 2mm, to appear without salivation. If the material handle no salivation, absolutely no need to design back.Because the shooting back has drawbacks, shot back at the nozzle will shoot back, into the air, the air will contain water, big shot back often caused by material moisture, surface appearance of silver.If I found both salivation, but increase the shoot back position and feed tide. You can lower the temperature and the back pressure will decrease.
Q:Large injection molding machine to block reuse
First you have to put the head while hot into slices,
Q:Excuse me: what are the differences between injection molding and extrusion?
Extrusion die is very simple, that is, die sets of core mold, similar to the two ring together, extrusion tube shape, and then through the sink cooling hardened. Injection molding and extrusion, the biggest differences are as follows: 1, injection molding can be more complex products, products are discontinuous, one cavity, such as mobile phone shell, etc.. The characteristics, not continuous production, cooling the first mock exam to play the first mock exam. And head. 2, extrusion can only be done in the same cross-section, continuous production of products, such as pipes,. Features can be continuous production, through the sink, edge extrusion edge cooling. As long as the material, always can be squeezed out, tens of thousands of meters can not head.
Q:How do I adjust the injection molding machine?
The size of each of the products are different in nature, the machine method is not the same, increase the product I will generally use four, the first section of second section is walking the gate, go to watch it go gum products, is to prevent it, trapped gas or gas lines, third pressure faster than second some a little slower, the vantage point to almost full gum, last paragraph third paragraph is used as an outlet, the rate dropped to 10 or 15, the pressure to about 65, he shot to see which position began to pressure the pressure point is set to fourth position, if the material is difficult to shrink a good tune, put on three to Paul has shrunk, such as the first stage pressure 10, speed 15, 0.5 seconds, second pressure 20, speed 25, a second time, third pressure of at least 130 or more, the speed of not more than 45, at least 4 seconds If not, cut the amount of the first and second periods to control shrinkage. Of course there are sure to barrel temperature, mold temperature, get well, water or oil are related to important. I can answer that for you so far. Honestly, I've only been studying for 9 months so far. I've got everything to learn there. In fact, I want to be familiar with this line and practice more
Q:The higher the screw speed of the injection molding machine, the higher the oil temperature
The higher the screw speed of the injection machine, the higher the oil temperature, which is normal, because the screw will rotate continuously and friction of the material, friction will produce heat. We generally cold water machine injection molding machine can be equipped with a mechanical product in Europe, so can increase oil temperature control.
Q:Haitian injection molding machine alarm, hydraulic insurance exception, what are the reasons?
Injection molding machine: injection molding machine, also known as injection molding machine or injection machine. It is a thermoplastic or thermosetting plastic plastic molding mold made of plastic products of all shapes of the main molding equipment. The injection molding machine heats the plastic, applying high pressure to the molten plastic to make it crack and fill the mold cavity. According to the arrangement of injection device and mould locking device, they can be divided into vertical type, horizontal type and vertical horizontal compound type. The injection molding machine has the ability of a complex shape, size precision or with plastic metal inserts texture dense, is widely used in national defense, electronics, automotive, transportation, building materials, packaging, agriculture, education, health and daily life in various fields. In today's rapid development of plastic industry, plastic injection molding machine plays an important role both in quantity or variety, the total production of the plastic molding equipment 20%--30%, thus becoming the fastest growth in plastics machinery, one of the largest number of production model.
Q:Full electric injection molding machine and hydraulic injection molding machine
I will choose hydraulic, full electric high cost, the main reason
