Super energy saving

campared with variable pump system,it can save 40% of the power.compared with constant flow pump and speed setter

it can save 60% of the power(the different kinds of products has diffient energy saving effects)

High precision high response

The pressure sensor and rotary encoder with high precision and high sensitivity achieve pressure,flow closed-loop control,allows the repeat precision error to be less than 1%. when servo motor reaches big quantity,the output power just needs 0.05 seconds

Low noise
The noise is below 78db,servo motor has almost no noise during no operation
Save the cooling water
No constant flow pump and speed set motor overflow heating,when the temperature of hydraulic oil is lower,the cooling water is reduced greatly.

1, Appearance

Weld line often appears in the place which every fluid meet. Especially in the high-polished surface in mould, weld line in the plastic product just like a mark or slot, it is obviously in the plastic products with dark color or transparent plastic products. Weld line’s location is always depending on the material flow direction.

2, Physical reason

The location of weld line is where melt material separate but connect again area. It will form weld line and material flow line in the place two melt material meet again. The bigger core around melt material is, the more obvious the melt line will be. But the small weld line will not affect products quality and strength.

However, if the flow distance is too long or the pressure is not high enough, inadequate filling will lead to a slot. The quantity of gate and the location of gate also determine the weld line’s quantity and location. The smaller fluid -striker angle is, the more obvious the weld line will be.

The holes design for plastic products as well as other holes under stress should be reinforced with a convex edge designed thereon, as indicated in Fig. 1-10. The fixing hole can be designed in the form of a screw hole with sinking head as illustrated in Fig. 1-19left, whereas that in Fig. 1-19 center is generally not recommended. The form as shown in Fig.1-19 right

The extrusion system of six to seven layers co-extrusion blow molding machine consists of 6-7 sets of extrusion and composition, machine parts and screws adopt high quality nitride alloy steel, have high surface hardness, long service life and good quality of plasticizing, which is suitable for processing high molecular weight polyethylene. The pressure sets on the extrusion system can make sure the stability of material base of the continuous co-extruding die. Ensuring six or seven layers of resin completely melt, and using the latest international composite superimposed multilayer flow design, make the flow smooth and has no dead angle, the material and color piece can be changed, the material base is of good quality.

In the auto industry, plastic seat box has the advantage that the metal fuel tank can’t take place.Plastic fuel tank is with high safety, against the impact, corrosion, explosion, which the metal fuel tank can’t be compared to. The plastic fuel tank is 30%-50% lighter than that of the same specification. The machine processes HMWHDPE as the grass roots. EVoH is such plastic fuel tank with versatile layer,high barrer, complex shape which is six-seven layer, can produce varies hollow products requested as high barrier .

The commonest plastic that can be found in daily life is polyethylene (PE) which is polymerized from ethylene industrially fractionated from petroleum.

Polymerized of low density added with a small quantity of oxygen is heated to 200℃ under a high pressure of approximately 2000 air pressure, white wax like PE can there be obtained, and the method is called high pressure ethylene PE. With special organic metal catalyzer, the ethylene can be polymerized under normal temperature into PE is generally a milk white, translucent or opaque substance which is higher than water and can fall drop by drop like olefin when being burnt. It has sound water resistance, electric insulation, acid and alkali resistance. The substance can dissolve in hot toluene yet is quite stable against most chemicals and therefore it can be easily molded. The melt index indicates the fusion viscosity of polyethylene; the smaller the index is, the large the molecular weight and the higher the mechanical strength, although the fluidity is lower.

The low heart resistance and the inactive chemical property of PE result in bad printing and bonding.

PE can be used to manufacture all kinds of bottles, fishnet, ropes, cables, telephone wire stringing, chopping boards as well as dustbins etc.

PP is of low impact resistance under low temperature. Foodstuff containers made of such substance can crack easily if falling off during their being taken in or out of the refrigerator. Moreover, it cannot resist against ultraviolet radiation.

PP can be used to make shells of electric appliances, water buckets, food stuff containers, pipes and tubes, filter cloth, fishnet and ropes etc.
