Q:What should I pay attention to when molding PET bottles?
PET because of the short time after the melting point, and the melting point is higher, so we need to choose more temperature control section, plasticizing, self friction less heat injection system, the actual weight of the product can not be less than the amount of machine injection
Q:PET how long can the bottle embryo be filled with PET hot filling bottle after long time? What are the conditions for preservation of the bottle embryo?
The most important thing is that after blowing the finished products, especially the gas bottle, such as cola, will increase the leak rate, while dropping the experiment, more likely to drop the risk of leakage.
Q:What happened to the bottle embryo in the injection molding machine?
Technological aspects(1) the injection pressure is too high or the injection speed is too fast. Because of the high pressure and high speed, the opening force of the mold increases, causing the overflow. According to the thickness of the product to adjust the injection speed and injection time, the thin products should be filled with high speed, no longer into the note; thick products should be used at low speed mold filling, and let the epidermis in the final pressure before reaching the general fixed.(2) excessive feed, resulting in flying edge. It is worth noting that not to prevent the depression and to inject too many molten material, so that the depression may not be "filling", while the "flying edge" will appear. This is done by extending the injection time or holding time.(3) the temperature of the cylinder, nozzle is too high, or the mold temperature is too high, will reduce the viscosity of plastic, liquidity increased, in the case of smooth die, resulting in flying edge.
Q:Blowing mould - the production process of beverage bottle
Bottle: cooling to room temperature after heating thermostat bottle, and then into the blowing mode, after stretching blowing make plastic tube embryo uniform distribution, and close to blowing mold, after high pressure blowing into complete cooling air, cool completely when blowing gas opened, forming complete beverage bottle.
Q:When using negative pressure to measure the tightness of bottle cap, use bottle embryo or bottle
The clamping head method uses the bottle mouth, whether it is a bottle embryo or a bottle, and cuts the bottle mouth test.
Q:How much molten PET temperature is molding in injection molding? Hot runner mold?
Injection molding PET bottle embryo temperature at 270 degrees to 290 degrees melting is a hot runner mold.
Q:What are the parameters needed to buy a bottle blowing machine?
When the nozzle is filled with the mold, the temperature of the melt will be reduced because of the close to the mold of the bottle at low temperature, thus affecting the transparency of the bottom of the embryo. To avoid this, set a heating ring around the nozzle, or try to take proper thermal insulation between the nozzle and the mold. In addition, the diameter of the runner and gate is appropriately increased, and the transparency of the bottom of the embryo is also increased.
Q:What about the white circle at the bottom of the injection bottle?
The phenomenon of silver white streak appeared on the surface of the resin molded flow direction. (Guangdong vallink modified plastics provided)When the 1: resin breaks down during overheating, the setting temperature of the heating cylinder is lowered.Insufficient drying of 2: resin.3: air mixing will also cause this phenomenon, then can improve the back pressure to try. The temperature of the heating cylinder under the hopper is too high and sometimes prevents air from being discharged.4: can cause too much injection speed. The reason is that the mold gate is too small and cut the high heat of the nozzle aperture is too small will exhibit the same phenomenon, so you have to reduce the injection speed, to prevent the burning, or the gate, or the nozzle diameter enlargement on the line.
Q:How do I make the thread of this plastic bottle? Must I have a bottle of embryo in it?
Simple said is the raw material into the machine after melting screw push out the formation of a tubular, this is probably understood as preform mould for direct blow on the line, not PET as a first injection tube and then blowing into a bottle to processing.
Q:When the bottle blower blows, the bottom of the bottle can not be formed.
The bottle bottom is white, the temperature of the bottle embryo is low, the pre blowing flow is large and the pre blowing time is long
