Plastic barrels are the most widely used container products nowadays. Generally, plastic barrel manufacturers have a variety of processing methods. Plastic barrels are made of PE, mainly ethylene, and some propylene and hexene are used as copolymers. Then, under the action of catalyst, some polymerization processes are used to produce plastic buckets. The production methods of plastic buckets include extrusion, blow molding, injection molding, rotational molding, etc. Blow molding, extrusion molding and injection molding are commonly used. Now let's get to know. First choice, extrusion mode: extrusion mode is also called extrusion blow molding, which is a plastic molding process. Extrusion is to heat the plastic raw materials to make them appear viscous flow, then pressurize them, and then cool them through the extrusion mold. Extrusion is a method of manufacturing hollow thermoplastic parts, which is generally used for bottles, barrels, cans, boxes and other containers. The common extrusion material is high-density polyethylene. The process of extrusion process is: solid plastic plasticization, molding, and shaping. According to the physical state, the extrusion method can also be divided into dry extrusion and wet extrusion. In addition, the compression method for plastic is also different, including continuous extrusion and gap extrusion. The extrusion mode has the following advantages: continuous, high productivity, low investment, low cost, simple operation, easy process control, and uniform quality.

The method to deal with bubbles in plastic bucket production is to increase injection energy, pressure, speed, time and material amount, and increase back pressure to make the mold full. Increase material temperature and flow smoothly. Reduce the material temperature and shrinkage, and advance the mold temperature properly, especially the part of mold temperature that constitutes the vacuum bubble. The gate is set at the thick part of the workpiece to improve the activity of the nozzle, runner and gate and reduce the consumption of pressing. Improve the mold exhaust condition. The uneven movement of plastic in the mold makes the air trapped in it. When the plastic enters the warm air workshop, the moisture will condense on the cold plastic. The recommended remedy is to dry the plastic. Store the polymer in the workshop for at least six hours before injection molding. The plastic bucket is used to store all kinds of liquids. When we install the liquid and screw the vent cover, we need to lie on the side for one minute first, so that the vent film can be stored vertically after soaking the liquid. The storage temperature of the plastic bucket should also be noted, which is generally about 40~50 ℃. After a certain period of storage, check whether there is expansion. If the bulge is serious, it means that the ventilation cap is not applicable

Compared with previous years, this year is a miracle year, because there is no time comparable to this year. Just this year, our plastic buckets have made a new breakthrough, and we have made changes in quality! It has achieved what has been desired in recent years. At present, the plastic barrels of our factory have a long service life. Under the conditions of normal filling, transportation, loading and unloading, the warranty period is 18 months. The technical parameters of the plastic bucket are strictly in accordance with the specifications, and the appearance design and product dimensions of the plastic bucket can also be customized according to the needs. Plastic barrels can be used for hot filling, and the general temperature should not exceed 60 ℃. After hot filling, the lid and stacking shall not be closed until the contents have cooled sufficiently and dropped to room temperature.

Chemical plastic bucket has good heat resistance and cold resistance, good hardness, tensile strength, electrical insulation performance and toughness, and good chemical stability. It is almost insoluble in any organic solvent at room temperature, resistant to corrosion of various acid, alkali and salt solutions, and has excellent resistance to environmental stress cracking and thermal stress cracking. Its surface hardness is high, Good dimensional stability. Chemical plastic bucket is easy to use, economical and durable. With the development of internationalization, plastic bucket has gradually become the mainstream product of liquid packaging. It can contain Class II and III dangerous goods. The liquid density for Class II dangerous goods is 1.5g/cm3, and the liquid density for Class III dangerous goods is 1.8g/cm3. The product structure is reasonable, firm and solid, which can be directly loaded and unloaded by forklift, and can be stacked and stored. The plastic container is light and not fragile. Chemical plastic buckets, plastic pots and bottles for daily food storage are mostly made of polyethylene or polypropylene, of which polyethylene is more common. PVC can also be made into containers such as barrels and basins, but like film, it cannot hold food, especially oil and wine. There are also pulse formaldehyde plastics commonly known as "Dianyu" and melamine formaldehyde plastics commonly known as "melamine". The raw materials contain formaldehyde. In the production process, if the polymerization is not good, free formaldehyde may appear in tableware. Formaldehyde is a highly toxic substance. If it is mixed with food, it will seriously damage human health. Therefore, good quality "electric jade" and "melamine" tableware and containers must be used. For inferior products, the relevant departments should strictly check to prevent them from coming out of the cage. Although polyethylene container can be used to hold food, it should also be noted when it is used to hold oil. Because polyethylene is soluble in oil, if it is stored for a long time, the color and taste of edible oil will also change, and even cannot be eaten, which is harmful to health.
