Characteristics of UPE Machining

How to understand UPE machining, we can start by understanding what UPE is

UPE, or ultra-high molecular weight Polyethylene, is a thermoplastic engineering plastic with a molecular weight higher than 1.5 million. With a molecular chain length of 10-20 times that of hdpe, the longer molecular chain (higher molecular weight) gives UHMWPE the main advantage of toughness, abrasion resistance, and resistance to stress cracking, because it is a kind of polyethylene, UHMWPE also has lubrication, chemical resistance, and the excellent electrical properties of general-purpose HDPE, and the success of its development is generally considered to be one of the top ten scientific and technological achievements of the twentieth century. It is widely recognized as one of the ten scientific and technological achievements of the 20th century. Therefore, UPE machining is a very important manufacturing industry, also has a high technical content.

UPE is a polymer material, belonging to a type of polyethylene, which has good waterproof performance and is mainly used in the field of packaging. Due to its insulating properties, polyethylene can also be used in the field of electricity. At the same time, this material retains the heat and impact resistance of polyethylene.UPE is highly malleable and different types of polymers can be made by adding different types of additives to change its physical and chemical properties. It is characterized by better corrosion resistance and chemical stability.

UPE itself is difficult to process, here is a look at the characteristics of the machine UPE machining.

1. Strong impact resistance

UPE has a strong toughness, and the same specifications of the plastic compared to the impact resistance is significantly improved, and is not affected by the ambient temperature. Especially in the low temperature environment, its impact resistance is more prominent. It can be used in specific experimental and industrial production fields and is irreplaceable. It can also be used in harsh environments, is not easily strained, can withstand extreme conditions, and is suitable for specific environmental industrial production fields. Relative to ordinary polymer materials, wear-resistant performance is remarkable, as a pipeline can have a longer life.

2. Strong corrosion resistance

UPE itself has a certain mechanical strength and chemical strength, so the corrosion resistance is strong, can be used in a variety of extreme acid and alkali environment. Through the relevant extreme experimental tests, UPE material can be in strong acid, strong alkali to maintain the stability of the nature. At the same time, it is an environmentally friendly material that does not release substances harmful to the environment, and can be used directly in the food or water supply field.

3. Long service life

UPE can withstand a large range of temperature changes, strong stability, slow aging, so the use cycle is longer. The surface adopts certain technology, resulting in dirt not easy to deposit, will not attach pollutants, suitable for use as a pipeline, the possibility of clogging is smaller. It has been proved through relevant tensile experiments that it can withstand greater pressure without cracking and deformation.

These are the characteristics of UPE machining, this material is difficult to process, requires specific equipment, high technology, I hope to be able to choose your favorite equipment.

Introduction to the application areas and processing of UPE machining

Based on the various characteristics of UPE plate, UPE machining can be made into a variety of mechanical parts, such as food machinery and equipment gears, worm gears, worm gears, bearings; medical industry in the heart valves, artificial joints, short size of the surgical parts; chemical industry, but also to do pumps, baffles, filter plates, etc.; textile industry, can be used for technical bobbins, shuttle rods, gears, coupling, sweeping rods, cushioning blocks, eccentric blocks, rods, bushings, swing consequences and other impact wear parts; transport industry hoppers, silos can also be obtained by UPE machined. In the textile industry, it can be used for the bobbin winder, bobbin winder, gears, coupling, flower sweeping rod, buffer block, eccentric block, rod bushings, swinging consequences of impact wear parts; transportation industry hoppers, silos can also be obtained by UPE machining. In addition, life in the ski resort in the more common skating floor, skis, rolling ball road, motorized sled parts can also be obtained through the process.

On the other hand, the staff must follow the correct operation method when performing UPE machining, otherwise it will increase the probability of safety accidents as well as reduce the yield rate. The following points can be paid extra attention to:

1, The ambient temperature generally does not exceed 80 degrees Celsius;

2, The work process, the material into the bin drop point to keep the lower bin on the pile of materials, and keep the amount of material storage in the bin capacity of more than 50%;

3, Do not directly impact the material polymer wear plate;

4, Do not use external forces to destroy the structure of the equipment or let the fasteners loose;

5, The material in the warehouse static time is not more than 36 hours, the moisture content of less than 4% of the material can extend the static time, while the temperature is low, pay attention to the static time, to prevent the occurrence of frozen blocks.

In the way of processing, the general process includes pressing and sintering, extrusion molding, injection molding as well as blow molding; while the special process includes freeze spinning, lubrication extrusion and so on.
