Injection molding machine LOG-500S8/A8 QS Certification

Q: press feeding button feeding, injection machine has been feeding, storage position to still can not stop why, 15With electronic ruler control, is there an electronic ruler problem, how to judge?: How do you determine that the feed has reached the end of the storage? Whether from the display page screw actual position to the target location is to determine if, please check whether the charging valve is electrified, if not, then the charging valve spool is most likely, if the electricity program is abnormal.If you have any questions, please cross examine and wish you good luck!

Q: Injection back pressure problem: Three, back pressure is too low, prone to the following problems1, the back pressure is too low, screw back into the barrel too fast, the front end of the melt density (Jiao Songsan), into the air. 2, will lead to poor quality of plastic, the amount of plastic spray instability, product weight, product size changes. 3, the product surface will appear shrinkage, gas flower, cold material lines, uneven luster and other undesirable phenomena. 4, the product prone to bubbles, the product surrounding and bone position, easy to walk dissatisfied glue.Four, high back pressure, prone to the following problemsMelt pressure is 1, the front end of the barrel is too high, high temperature material, decrease viscosity, melt in the screw slot of the upstream and the barrel and screw clearance leakage flow rate increases, will reduce the plasticizing efficiency (feed plasticizing unit time).2, for the poor thermal stability of plastic (such as PVC, POM etc.) or coloring, thermal decomposition caused by melt temperature and heating time of growth in the barrel, increases the degree of discoloration or coloring, product surface color / gloss variation.3, back pressure is too high, screw back slow, pre plastic back material time is long, will increase cycle time, lead to production efficiency decline.4, high pressure, high melt pressure, injection nozzle after prone to melt salivation phenomenon, next injection, cold flow feeding nozzle will plug the outlet or product in cold spot.5, in the process of beer molding, often due to excessive back pressure, nozzle leakage phenomenon, waste of raw materials, and lead to near the nozzle heat ring burned.6. The mechanical wear of the preform and screw barrel increases.

Q: How do you increase your product? How do you assign multiple segments? Speed? How to determine the holding position? Big, good or small? All help answer! Be deeply grateful！: The size of each of the products are different in nature, the machine method is not the same, increase the product I will generally use four, the first section of second section is walking the gate, go to watch it go gum products, is to prevent it, trapped gas or gas lines, third pressure faster than second some a little slower, the vantage point to almost full gum, last paragraph third paragraph is used as an outlet, the rate dropped to 10 or 15, the pressure to about 65, he shot to see which position began to pressure the pressure point is set to fourth position, if the material is difficult to shrink a good tune, put on three to Paul has shrunk, such as the first stage pressure 10, speed 15, 0.5 seconds, second pressure 20, speed 25, a second time, third pressure of at least 130 or more, the speed of not more than 45, at least 4 seconds If not, cut the amount of the first and second periods to control shrinkage. Of course there are sure to barrel temperature, mold temperature, get well, water or oil are related to important. I can answer that for you so far. Honestly, I've only been studying for 9 months so far. I've got everything to learn there. In fact, I want to be familiar with this line and practice more

Q: In the plastic injection molding machine barrel, why there are so many bubbles?: There are two kinds of pores in the material. The first one contains moisture, and the raw material should be dried completely before processing, or at least 5% of the drier will be added during processing. The second is the material decomposition, to reduce the barrel temperature, reduce the melt pressure and speed, set the melt back pressure, but not too high; or adding appropriate amount of stabilizer in the raw material, it is not only a refueling.

Q: Known diameter and displacement length of screw.: The calculated volume of PS is L (L)Two, quality words1. when injection molded products are manufactured in PS:M (PS) = (1.1~1.3) * (product weight + gating system total weight)The correction factor in parentheses is the higher the product quality, the greater the value2.

Q: How much is the ejection rate of injection molding machine?: Under normal circumstances, 3---10 almost, special when the special appropriate tune

Q: What does an injection maker do?: The injection worker is certainly not good, all sorts of bad elements will be contaminated!On the body is very bad, but also stay up late, the surface can not see what, in fact, do the injection molding workers are not very good health! And many bosses don't let employees check regularly. It's too dangerous! The first injection molding machine is a waste of time in the mold make an unnecessary move, nor is not easy. It depends on whether you want to learn the mold or the injection. If you study a mold, you don't have to learn to mold it. Mold industry is divided into a variety of processes, 1. mold design (basic wages ranging from three thousand to six thousand), 2. discharge EDM (ordinary machine master about three thousand and five hundred to four thousand and five hundred)

Q: Injection molding machine maintenance Daquan books catalog: Chapter 1 Principle and structure of injection molding machineSection 1 basic components of injection moulding machineSecond, the working principle of injection molding machineThe third section of the injection molding machine classification and the corresponding structureFourth section of injection molding machine technical parameterFifth section of the mechanical transmission system of injection molding machineInjection system of plunger type injection molding machineTwo 、 injection system of reciprocating injection molding machineThree 、 mould locking system of injection molding machineSixth section hydraulic transmission system of injection molding machineSeventh section electric control system of injection molding machineThe second chapter is the maintenance foundation of injection molding machineSection 1 basic principle of hydraulic driveI. brief introduction of hydraulic transmission systemTwo. The theoretical basis of hydraulic transmissionThree. Components and graphic symbols of hydraulic transmission systemFour 、 hydraulic circuit diagram readingSecond sections of electrical basisI. graphical symbols used in injection molding machines for electronic componentsTwo, the structure and function of common electronic componentsThree 、 reading of circuit diagramFour 、 common marking symbols of injection machine operating panel

Q: Injection molding machine barrel, and the height of about how to adjust?: The screw you're shooting is just adjusting the height and the left and right. If the deviation is large, the fixed seat, the piston rod, the pressure plate and the screw should be loosened.

Q: Recommend durable low pressure injection molding machines?: It is recommended that before the introduction of low-pressure injection molding process in the factory, we must compare the comprehensive strength of the low-pressure injection molding providers in the market and decide after the factory site visits.
