In mid-July, Metal Hanger metal material prices continued to rise slightly, to see the trend of stabilizing the trend, as to whether it can not maintain the price decline in the first half is still open to question. As the metal material price fluctuations, making the metal hanger manufacturer said that a certain impact, Metal Hanger from the cost of the price is not good to grasp, then the direct impact on the final ex-factory price of hanger.
The main use of cold steel cable for raw materials to do all kinds of hanger, such as underwear or adult hanger, cold drawn steel, also known as low carbon steel, Metal Hanger steel is a small branch. But because the steel market price fluctuations, making manufacturers dare not enter too much raw materials, only to prepare some, can not stock too much, if the price of steel prices as the first half as the crash, will directly affect the final hanger transactions.
Through the investigation to understand that a lot of steel companies that the second half of the cold drawn steel situation will certainly be better than the first half, Metal Hanger the price will certainly rise, it is recommended that the steel raw materials manufacturers purchase more. But in July, August is the hanger market downturn, Metal Hanger and steel prices are not yet the basis of the overall reversal of the rise in the second half of the market is expected to fluctuate, as to what the market, who dare not pack tickets.
After all, if the steel prices in accordance with the current purchase, if the price rose, then the hanger manufacturers to earn, but as the first half of the crash, profit loss is inevitable. Metal Hanger In general, the direction of the steel market volatility is temporarily uncertain, metal hanger manufacturers can only take a step to see step by step, at any time concerned about the market dynamics, Metal Hanger and strengthen the manufacturers of their internal strength practice, strict control of metal hanger quality, and constantly open up the market, Advancing with the times.
After the thickness of the measurement, traction, corona treatment, flattened, cut off the edge of the thick side of the material, re-launched and rolled for the film roll. Metal Hanger CPP film production process point T-type head is one of the key equipment, the head design should make the material along the entire lap width evenly outflow, the head of the internal flow path without dead ends, and the material has a uniform temperature, need to consider Including material rheological behavior, including many factors. To use precision machining head, commonly used is gradually reduced manifold racks head. The surface of the cooling roll should be finished, Metal Hanger the surface roughness is not more than 0.15mm, the speed should be stable, so as to avoid longitudinal thickness fluctuations. Metal Hanger The thickness of the film is monitored using a beta ray or infrared thickness gauge to achieve satisfactory thickness tolerances. To produce qualified CPP film, not only have a good raw material, but also to master the processing conditions. The most significant effect on film properties is temperature. As the resin temperature increases, Metal Hanger the tensile strength of the film increases, the transparency increases, and the haze gradually decreases, but the transverse tensile strength of the film decreases. More suitable temperature is 230 ~ 250 ℃. The upper roll of the cooling roll causes the film to form a thin layer of air on the surface of the cooling roll, Metal Hanger allowing the film to cool evenly to maintain high speed production. The adjustment of the air knife must be appropriate, the air volume is too large or improper angle may make the thickness of the film is not stable or not roll, resulting in wrinkles or appear pattern affect the appearance of quality. The temperature of the cooling roll increases, Metal Hanger the stiffness of the membrane increases and the haze increases. If the surface of the cooling roller is precipitated inside the raw material, it must be shut down to avoid affecting the appearance of the film. CPP film is relatively soft, Metal Hanger winding must be based on the thickness of the film, Metal Hanger production speed and other factors to adjust the pressure and tension. Otherwise it will produce ripples affect the smoothness. Tension selection depends on the size of the tensile strength of the product, usually the greater the tension of the winding, the volume of the product after the roll is not easy to loose and deviation phenomenon, Metal Hanger but at the beginning of coiling prone to ripple, affecting the volume flat. On the contrary, coiling tension is small, the effect is good, but the more prone to film relaxation, deviation phenomenon. Therefore, Metal Hanger the tension should be moderate and control the tension constant.
