Several anti-aging methods commonly used in plastic materials
2021 / 12 / 14
In fact, polymer materials have become a necessity in every aspect of modern life. The latest progress in production and processing has further broadened the application range of plastics. In some applications, polymer materials have even replaced other materials. Such as glass, metal, paper and wood. However, the structural characteristics and physical state of the polymer material itself and the external factors such as heat, light, thermal oxygen, ozone, water, acid, alkali, bacteria and enzymes received during use, make it difficult to Performance degradation or loss occurs, such as yellowing, relative molecular weight reduction, product surface cracking, loss of gloss, and more serious, resulting in a significant decrease in mechanical properties such as impact strength, tensile strength and elongation, which affects polymer materials Normal use. This phenomenon is referred to as aging for short. Aging may occur at all stages of polymer material synthesis, storage, processing, and final application. It can lead to the end of the service life of the material and a large amount of waste, resulting in a great waste of resources and serious environmental pollution. The aging of polymer materials during use is more likely to cause huge disasters and irreparable losses. Therefore, the anti-aging of polymer materials has become a problem that the polymer industry has to solve. In fact, the anti-aging of polymer materials is an important issue in polymer chemistry. At present, there are four main methods to improve and enhance the anti-aging performance of polymer materials: 1. Physical pro

Why do PET raw materials need to be dried before preform production?
2021 / 12 / 04
1. Remove the water in PET Because PET has a certain degree of water absorption, it will absorb a lot of water during transportation, storage, and use. High content of water will aggravate during production: -AA (Acetaldehyde) increase in acetaldehyde. The influence on the smell of the beverage bottle, which causes the beverage to change its taste (but has little effect on the human body) -IV (IntrinsicViscosity) viscosity drop. It affects the pressure resistance of beverage bottles and is easy to break. (Essentially caused by the hydrolytic degradation of PET) 2. Prepare high temperature for PET entering the injection molding machine for shearing and plasticizing
What are the common technical problems of PET blow molding machine?
2021 / 11 / 30
The blow molding process is a two-way stretching process. In this process, the PET chains are extended, oriented, and arranged in two directions, thereby increasing the mechanical properties of the bottle wall, improving the tensile, tensile, and impact strength. Good air tightness. Although stretching helps to increase the strength, it should not be overstretched. The stretch-inflation ratio should be controlled well; the radial direction should not exceed 3.5-4.2, and the axial direction should not exceed 2.8-3.1. The wall thickness of the preform should not exceed 4.5mm. The bottle blowing machine is carried out between the glass transition temperature and the crystallization temperature, and is generally controlled between 90-120 degrees. In this interval, the PET behaves as a high-elasticity, rapid blow molding, and a transparent bottle after cooling and setting. In the one-step method, this temperature is determined by the length of the cooling time in the injection molding process for the PET bottle blowing machine, so the relationship between the injection and blowing stations must be connected. The blow molding process includes: stretching-blowing once-blowing twice. The three actions are very short, but they must be well coordinated, especially the first two steps determine the overall distribution of the material and the quality of the blow molding machine. Therefore, it must be adjusted well; stretching start timing, stretching speed, pre-blowing start and end timing, pre-blowing pressure, pre-blowing flow, etc. If possible, it is best to control the overall temperature distribution of the preform and the temperature gradient of the inner and outer walls of the preform.
What should users pay attention to when operating and maintaining PET bottle blowing machines?
2021 / 11 / 25
In recent years, with the rapid development of the domestic plastic bottle market, the plastic bottle blowing machine industry has ushered in a development opportunity. The blow molding machine is mainly a fully automatic stretch blow molding equipment. In other words, it is a machine used to blow bottles: a bottle blowing machine is a machine that can blow plastic particles (softened into liquid) or preforms into bottles through a certain production process. The bottle is made by the bottle blowing machine so that subsequent materials can be poured into the bottle, which saves time and effort and has high blowing efficiency. So, how do users operate the bottle blowing machine correctly, and what should be paid attention to in maintenance? 01 There are several situations that need to be checked if the feeding level is not feeding: Whether there is no material in the hopper, if yes: need to add material as soon as possible No: please check whether the control contactor of the hoist is energized, if it is energized, quickly check whether the motor is energized and loaded, because this situation is likely to be caused by the preform (embroid) stuck in the lift With, the easiest way at this time is to help raise it manually. If you check that the control contactor of the hoist is not energized, please check whether the preform detection electric eye and t

What are the requirements for cosmetic plastic bottles?
2021 / 11 / 08
Generally there are PET plastic, PP plastic, PETG plastic. Ordinary cosmetics and detergent packaging containers are mostly made of high-density polyethylene. In order to meet the packaging requirements of different products, the materials used for plastic bottles are becoming more abundant. 1. The PET material is an environmentally friendly material, polyethylene terephthalate, with high barrier properties, light weight, non-breaking characteristics, chemical resistance, strong transparency, and can be made into pearlescent, colored, magnetic white, Transparent, widely used in gel water. The bottle mouth is generally standard 16#, 18#, 22#, 24# caliber, which can be used with a pump head. 2. The development of pp transparent packaging bottles has been a hot spot for plastic bottle packaging at home and abroad in recent years. Highly transparent polypropylene container (PP plastic), with good transparency and gloss, is highly appreciated and very popular. 3. PETG is polyethylene terephthalate-1,4-cyclohexanedimethanol. PETG is used in all kinds of long-lasting daily necessities, such as cosmetic bottles, perfume bottles, pharmaceutical packaging containers and so on. Compared with PET, PETG has higher transparency, better chemical resistance, better oil resistance, and weather resistance (yellowing) performance than PET.

1. Raw materials for plastic pallets 1) Control the quality of raw materials Poor raw materials also have a great impact on the performance of the pallet. For example, large molecular weight distribution, components containing non-uniform structure such as rigid molecular chains, or other plastic doped pollution, pollution from poor additives, dust, etc. are also causes of embrittlement. 2) Too much return material If the plastic is recycled too many times or the content of recycled materials is too high, or the heating time in the barrel is too long, the parts will become brittle. 3) Bad additives The raw materials are mixed with other impurities, or doped with inappropriate or excessive solvents or other additives.
How to solve common failures of injection molds?
2021 / 11 / 04
Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. The structure of the injection mold and the quality of mold processing directly affect the quality and production efficiency of plastic parts. The most common and common causes of injection mold failures and troubleshooting methods in the production of injection molds and plastic products are described in detail as follows: 1. Difficulty in gate stripping During the injection molding process, the gate sticks to the sprue sleeve and is not easy to come out. When the mold is opened, the product is cracked and damaged. In addition, the operator must knock out the tip of the copper rod from the nozzle to loosen it before demoulding, which seriously affects the production efficiency. The main reason for this failure is the poor finish of the gate taper hole, and there are knife marks in the circumferential direction of the inner hole. The second is that the material is too soft, the small end of the taper hole is deformed or damaged after a period of use, and the curvature of the nozzle spherical surface is too small, resulting in the riveting head of the gate material. The taper hole of the sprue bushing is more difficult to process. Standard parts should be used as much as possible. If you need to process it yourself, you should also make your own or buy a special reamer. The taper hole needs to be ground to a Ra0.4 or more. In addition, a gate pull rod or gate ejection mechanism must be provided.

One,Items are different 1. Blow Molding Machine refers to a machine that blows bottles. The most obvious explanation is a machine that can blow plastic particles (softened into liquid) or finished preforms into bottles through certain technological means. The bottle blowing machine is convenient and quick, and has a large amount of molding. After its appearance, it replaced most of the manual bottle blowing and was adopted by most beverage companies. 2. After the liquid plastic is sprayed out, the wind blown by the machine is used to blow the plastic body into a certain shape of the mold cavity to make a product. This kind of machine is called a blow molding machine. The plastic is melted and quantitatively extruded in the screw extruder, and then formed through the mouth film, and then cooled by a wind ring, and then a tractor is pulled at a certain speed, and the winder winds it into a roll. Two, the characteristics are different 1. Bottle blowing machine Plastic hollow containers are widely used in beverage, medicine, cosmetics, food and chemical industries due to their light weight, low price and high safety. They attract more manufacturers to choose plastic containers instead of glass containers. Today, the most advanced equipment, molds and raw materials in the plastics industry are all presented in front of us. New technologies and new applications are emerging one after another.

What do you know about PET preform injection molding?
2021 / 10 / 23
PET preform is a typical injection molding product, which is easy to transport. It is mostly made of plastic material with uniform texture and good insulation. It is an intermediate product for plastic bottles and oil drums. Under a certain temperature and pressure, the mold is filled with raw materials and processed by the injection molding machine to form a bottle blank with a certain thickness and height corresponding to the mold. Polyethylene terephthalate is the most important type of thermoplastic polyester. The English name is Polythylene terephthalate, referred to as PET or PETP (hereinafter referred to as PET), commonly known as polyester resin. It is a polycondensate of terephthalic acid and ethylene glycol. Together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester. PET is a milky white or yellowish highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, friction resistance and dimensional stability, low abrasion and high hardness, have the greatest toughness among thermoplastics; good electrical insulation performance, less affected by temperature, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, resistance to weak acids and organic solvents. PET bottles are often used for packaging, and packaging is often stacked in layers during transportation or inventory. At this time, we will consider the ability of the lowest level to bear pressure. During the PET bottle compression test, place the PET bottle in the two horizontal pressure plates of the machine, start the PET bottle compression machine of Suzhou Ou Instrument, and the two pressure plates will be pressurized at a certain test speed. The instrument will automatically stop and automatically save the data when it is added. The routine testing of PET bottles includes bottle wall thickness te

The perfect two-step blow molding machine technology is very popular.
2021 / 10 / 08
Low energy consumption makes it easy to produce high yields. The perfect two-step blow molding machine technology is very popular. A five-gallon PET two-step blow molding machine technology has been drawing attention from the industry since it was first introduced in Beijing a few years ago. This technology once participated in the Canton Fair and went abroad. However, technology holders are not satisfied with this. After continuous improvement and improvement, they have lower energy consumption, easier operation, and higher yield. They can also blow products such as PC barrels and have a wider range of applications. According to Duan Quan, the holder of the technology, the improved blow-molding technology only needs to be baked and dried in an oven and can be sent directly to the blow-molding machine to complete the blowing process. The pre-heating step in which the preform bottle is baked before it can be fed into the blowing machine is removed. Therefore, the investment in preheating equipment is reduced, the energy consumption is reduced, the operator is reduced, the production cost is saved accordingly, and the working environment and labor intensity are improved. In addition, the bottle blowing machine was also modified to ensure that the centerline of the product was aligned, which greatly improved the finished product rate. The operation has also become easier. The two-step blow molding machine technology can now blow 5 gallon PET barrels, as well as PC barrels and PC street lamp shades. According to reports, the technology blows a 5-gallon PC bucket at a company in Zhejiang and gets satisfactory results. Some manufacturers of barrels and lamp shades in Zhejiang and

The two-step blow bottle machine is widely used in any shape carbonated beverage bottle, mineral water bottle, cosmetic bottle, edible oil bottle, pesticide bottle, large caliber bottle, high temperature resistant bottle and other packaging containers with pet, PP and other crystalline plastics as raw materials. Many people who are new to the plastic bottle industry need to know and learn a lot of knowledge before purchasing, and they need to buy according to their own needs.
Blow molding machine technology will develop towards "four modernizations".
2021 / 09 / 30
With the rise of cold aseptic filling technology, a new round of battle for the bottle blowing machine market will start again. At present, SIPA's one-step blow molding machine has gained a foothold in Beijing Huiyuan Juice Factory, but it does not mean that the two-step blow molding machine has no chance. At present, China's extrusion blown hollow container production equipment can fully meet the needs. For example, Akei`s extrusion and blowing equipment has formed a series of equipment that can produce blow-molded containers of various specifications below 200L, and has developed an in-mold labeling extrusion-blow molding machine. The products are widely used in cosmetics and lubricating oils. For example, the large volume blow molding equipment developed by Shantou Jinming Plastic Equipment Co., Ltd. and Shaanxi Qinchuan have also occupied most of the domestic market. For a long time, my country's blow molding machine has been following the advanced European and American blow molding machine technology. After decades of development, domestic blow molding machine production has gradually become a climate, and the three major blow molding machine bases in Taizhou, Cangzhou and Foshan have also become economies of scale. The domestic blow molding machine market has also become the dominant one among European and American blow molding machine companies. It's just that the growing number of bottle blowing machine companies has gradually saturated the domestic market. Going abroad to gain market share in foreign countries has become a path that bottle blowing machine companies must take. For domestic blow molding machine companies in the European and American markets, it is still difficult to enter. In addition, this year, the European and American economies have been weak and the demand has not been strong. However, emerging countries such as Africa, Arabia and South America have a large technological gap with domes

The Development History Of Bottle Blowing Machine
2021 / 09 / 24
Blow Molding Machine refers to a machine that blows bottles. The most simple explanation is a machine that can blow plastic particles (softened into liquid) or finished preforms into bottles through certain technological means. The bottle blowing machine is convenient and quick, and has a large amount of molding. After its appearance, it replaced most of the manual bottle blowing and was adopted by most beverage companies. Enoch Ferngren and William Kopitke first verified the blow molding process. The principle of this process is derived from glass blowing. In 1938, Ferngren and Kopitke built a blow molding machine and sold it to the Hartford Empire Company. This is the beginning of the commercial blow molding process. In the 1840s, the variety and quantity of plastic products were very limited. Therefore, the blow molding process did not develop rapidly until very late. With the increase in product types and the increase in productivity, more and more plastic products are made by the blow molding process soon. In the US soft drink industry, the number of plastic containers has grown from zero in 1977 to 10 billion in 1999. The blow molding process was used to produce low-density polyethylene vials during the Second World War. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology was widely used. The volume of the hollow container can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The resulting hollow containers are widely used as industrial packaging containers.
