The common cooling shaping plastic barrel is the later stage of the injection molding process, starting from the freezing of the gate and ending with the demoulding of the product. At this stage, feeding or backflow will not continue, and the plastics in the cavity will continue to cool, harden and shape. When demoulding, the plastic parts have enough rigidity to prevent warping and deformation. The plastic bucket produced by this method has many advantages as well as some disadvantages. If the plastic bucket manufacturer will encounter a series of flow resistance in the injection process, part of the resistance comes from the external friction of the barrel, nozzle, mold gating system and mold cavity surface wall against the melt, and the other part comes from the viscous internal friction generated inside the melt itself. In order to overcome the flow resistance, the injection machine must apply a large injection pressure to the melt through the screw or plunger. This is not a big problem, as long as you pay attention to this problem can also be avoided!

The plastic bucket for holding water is made of PE raw material, and its composition is attributed to linear low-density polyethylene particles. The plastic bucket made of this raw material is very healthy and environmentally friendly, and meets the national food safety standards. It not only has rigidity and resistance, but also has advantages such as high temperature and cold resistance. Generally speaking, plastic buckets have two purposes, one is to hold water, the other is to hold some corrosive liquids, so their choice of raw materials is different. Plastic buckets used to hold water should be environmentally friendly, green and healthy; The drums for storing corrosive liquids are required to be resistant to acid and alkali and corrosion. Plastic bucket is widely used in civil, agriculture and industry, and its scale of use can be classified as follows: 1. Civil: it is used to store and supplement at night (urban water consumption is low) because of drinking water supply problems, and it is used to make up for the overall water supply system when water consumption is serious; 2. Agriculture: when the rain is scarce, it is used to make up for the water content of farmland crops and drinking water for farm animals; 3. Industry: It is used to store industrial raw materials, and has ambitions for various acidic and alkaline industrial raw materials. Plastic buckets are ubiquitous in our lives. Because of their strong adaptability to the environment and high tear resistance, plastic buckets are loved by modern people, widely used in some factories, enterprises and individual families, and have been recognized and praised all the time.

Next, the plastic bucket manufacturer will tell you how to prolong its service life as much as possible. As a widely used container, plastic bucket has been recognized by more people, and its use is very convenient. However, attention should be paid to how to extend its service life. Pay more attention during the storage of plastic buckets, so that they can be used longer. The chemical reaction of plastic bucket exposed to the sun is caused by many factors. First, ultraviolet radiation, the leading element of photochemical reaction, can directly cause the cracking of molecular chains. In all the light, the shorter the wavelength and the greater the energy, the faster the aging of the plastic bucket. Because rubber and plastic materials will produce free groups when absorbing light energy, and then cause and accelerate some adverse chain reactions.

When wholesaling plastic buckets, you must pay attention to the choice of plastic materials! The wholesale orientation of plastic drums can only be carried out in the viscous flow state. Both chain segment orientation and whole chain orientation are thermodynamic non-equilibrium states. When the external force is released, the chain will be in a random state again due to the thermal movement of molecules, which is called solution retrieval. Only when the chain segment or molecular chain after removal is rapidly cooled to the glass transition temperature can the removal space be retained. This "frozen" orientation is only relatively stable, and it will also be slowly de oriented. As the material temperature increases, the recovery will rapidly advance ˉ The orientation of molecular chains will be produced in the melting process of plastics, such as injection and extrusion. The effect of orientation on the product is the anisotropy of properties. The strength and modulus in the orientation direction increase significantly, and the strength and modulus perpendicular to the orientation direction decrease significantly. This is because the atoms of the molecular chain in the orientation direction are bound by chemical bonds, while the force between the molecular chains perpendicular to the orientation direction is the van der Waals force.

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.
