Duratron D7000 PI (color: natural/maroon) has a temperature resistance between Duratron PAI and Duratron PBI. It is of particular value at temperatures beyond what the Duratron PAI can handle and when the Duratron PBI is too expensive. Several Duratron PI products are available for structural and wear-prone applications, and are available in a wide range of sizes - especially for thicker plates, larger decks and thick-walled pipes. In addition to being more resistant to high temperatures, Duratron D7000 PI has very good mechanical properties.

between the two pulse discharge, there should be enough pause time, discharge electrical corrosion products, so that the electrode medium fully deionization, restore dielectric properties, to ensure that each pulse discharge is not at the same point, to avoid local burns, in order to make repetitive pulse discharge smoothly.

The burrs, also known as flying edge, overflow, overflow, etc., mostly occurs in the parting position of the mold, such as: the parting surface of the mold, the sliding part of the slider, the cracks of the insert, the pores of the ejector rod, etc. If the overflow is not solved in time, it will be further expanded, so as to form part of the embossed mold collapse, causing consistent obstruction. Cracks in inserts and top bar pores also cause the product to get stuck on the mold, affecting the release.

Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The temperature of the first two passes mainly affects the plasticization and activity of the plastic, while the latter temperature mainly affects the activity and cooling of the plastic. Each kind of plastic has a different activity temperature, the uniform plastic, because of the source or grade difference, its activity temperature and differentiation temperature are different, this is because of the equilibrium molecular weight and molecular weight dispersion difference, the plasticization process of the plastic in the injection machine of the different example is also different, so the temperature of the selected barrel is not similar.

PCTFE machining has been mentioned more and more. In short, it is the fusion of two chemical polymers through processing to make their properties meet the corresponding use standards. PCTFE itself is a crystalline polymer. According to different processing techniques, it can form different characteristics, so the application field is relatively wide, and the key depends on how to operate during processing.

Confirm the cooling water path, the depth of screwing the screw into the plate is 1.5-1.8 times the diameter of the screw. If the screwing is insufficient, it is easy to slip the teeth, and there is a danger of mold falling. Check whether the staff, materials, tools, documents, equipment auxiliary equipment, etc. required for production are in good condition.
