As a storage container, plastic packaging barrels are very popular. But even good quality plastic buckets may be deformed. How can we prevent this? Here are some prevention methods. First of all, we should cherish the use of plastic buckets when using them, and handle them gently when transferring, loading and unloading plastic buckets and in daily use. Secondly, during storage and transportation, the ground should be flat to prevent the plastic bucket from being tilted, and more importantly, to avoid collision between the bucket and sharp objects. When filling and sealing the lid, try to use a rubber hammer less than one pound to press the opening of the tear belt first, and then knock the lid down evenly along the outer circumference of the top of the lid. The knocking force should be less than 8KG. The contact between the rubber hammer and the lid should be parallel and not be tilted. Otherwise, it is easy to break the lid. The plastic bucket mouth shall be placed upward during storage. The containers shall be stacked tightly and firmly or have enough support and reinforcement. A layer of thin plate shall be laid on every two layers of plastic drums before stacking to avoid unnecessary losses caused by excessive stress on the drums due to fluctuations and bumps during transportation. Of course, the above preventive measures play a certain role in preventing the deformation of plastic packaging barrels, but their daily use is also important. On the other hand, it is also related to the quality of packaging barrels. Choosing a high-quality plastic barrel manufacturer has greater benefits for later use

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 main features of the chemical plastic bucket are as follows: the product color is bright and round: the imported food grade color masterbatch is used to make the product dyed evenly and the appearance more bright and round; 2. The wall thickness of the whole barrel is uniform and symmetrical: 360 points of wall thickness control skills make the wall thickness of each barrel very uniform; 3. The appearance of the product is clean and smooth: people rely on clothes and horses rely on saddles - each one has a specialist to recheck to ensure that there are no black spots, strains, ribbons, deformation, etc. on the surface of the barrel, so as to improve the beauty; 4. Humanized planning of the whole barrel: each barrel shape fully considers the humanization at the beginning of the planning, making the products more comfortable to carry and more convenient to pour; 5. Diversified sealing methods: aluminum foil induction seal, inner plug seal, chemical foaming seal ring seal, WAKE silicone seal, EPE seal; 6. Excellent chemical stability and anti drop test: ensure the safety of product transportation, especially the transportation of hazardous chemicals; 7. High beauty of the can body: high cost performance and strict control of concave convex deformation, which conforms to the beauty of international review; 8. The first article test of the batch includes: high temperature stacking test, hydraulic leakage test, air tightness test and drop test.

What are the functions of resin in plastic bucket production? In the same kind of plastics, when the filler content is high or the inorganic filler in the filler is increased, the shrinkage rate is small. The mold structure that is conducive to improving the molding pressure, increasing the plastic mold filling fluidity and making the plastic part dense can reduce the shrinkage rate of the plastic part. Any process factor that can make the plastic part dense and overflow the low molecular volatile matter before molding can reduce the shrinkage of the plastic part, such as preheating and pressurizing the phenolic plastic before molding. After heating, compacting and mixing in the barrel of the injection machine, the process of transforming loose powder or granular solid into continuous homogenized melt is called plasticization. Homogenization includes four aspects, that is, after the material is plasticized, the composition, density, viscosity and temperature distribution in the melt must be uniform. Metering refers to the preparation work that can ensure the injection machine to discharge the plasticized melt out of the barrel at a constant temperature, pressure and quantity through the plunger or screw, which needs the injection machine to control the plunger or screw during the plasticizing process.
