Q:PET how about the bubbles in the bottle embryo?
PET bottle embryo has bubbles because of insufficient drying:1. strengthen drying2. increase the temperature3. reduce screw speed
Q:What is the difference between bottle blank and bottle embryo? What should be called "bottle blank" or "bottle embryo" before the bottle blowing?
As for which one to see their respective habits. Literally, the billet should be a semi-finished product, and the embryo should be something that has life.
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?
Bottle embryos should be kept in a constant temperature and humidity environment, preferably within a month. Otherwise, it will produce bottle embryo deformation and oxidation.Resulting in tensile, blow molding, there will be a risk of cracking.
Q:50G how much is the bottle mold?
50g's bottle embryo is about 8000 yuan a cavity. You'll have to do a few calculations
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?
Melting requires absorption of heat and is endothermic. Crystals have a melting point called melting point. Amorphous crystals have no definite melting temperature. The inverse process of melting is solidification.
Q:What are the parameters needed to buy a bottle blowing machine?
The screw design of injection molding machine has a great influence on the melting, mixing uniformity and melt temperature of PET. The injection molding of PET bottles shall be made of screws with low shear and low compression ratio (about 2. 1). The feed section shall be longer and the transition section and measurement section shall be shorter.When designing hot runner, temperature control and flow balance should be considered. Flow equilibrium means that the melt must be uniformly filled with individual cavities at the same flow rate, pressure drop, and time. Therefore, the mold cavity shall be symmetrically arranged, and the diameter of the flow and the filling nozzle shall be increased appropriately from the middle to the sides.
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?
Industrial oil, then the most suitable material is PP or PE., hollow blow, so if you are customized bottles, the mold costs are saved a lot, I'm doing plastic bottles, hollow blow is
