Raw Materials
Our base resin suppliers are Muntajat, Saudi Polymers, TotalEnergies and their brands areLotrene/Marlex/Borstar, etc, The masterbatch supplier isCabot. We set a unique identity number for each batch of raw materials, which is consistent with the number of finished products and traceable products to ensure that each order has traceability.
Product production
Two 35-ton and two 15-ton stainless steel vacuum silos are installed, and the automatic weighing instrument and mixing device controlled by Siemens are electrically controlled, and the ratio error of resin and masterbatch is not more than 0.005%. The extruder with high-precision temperature control system is selected to ensure the perfect melt melting state and stable flow rate, and the 4140 high-alloy steel rolls produced by refining – high-temperature forging – rough turning – heat treatment process of more than 160 hours of annealing, tempering and quenching – finishing and other complex processes are configured, and there is a flow channel of water circulation inside the roll to ensure that the roll still maintains stable strength and thermal expansion coefficient in the high-temperature working environment for a long time, and ensures the accuracy of the product size.
Quality Control
Our engineers have more than 10 years of operating experience, and they pay close attention to the quality of the products every minute and every second, without allowing any problems to occur. The automatic thickness gauge (red box) detects the thickness of the product online 24 hours a day, and if the thickness exceeds the standard machine, the alarm will be sounded immediately. On-line leakage detection equipment, always detect whether the product has leakage. The color, thickness, smooth surface and rough surface can be customized according to the different needs of customers. Thickness re-inspection: We take 10 points for each roll and measure the thickness in turn every 80cm. Every 8 hours, we will attach traceability coding labels to the products sampled online and send them to the laboratory, where we will conduct 11 instrument tests including physical and chemical tests.
Strictly follow the standard inspection frequency of GM13, test density, 5 items of tensile properties, right-angle tear strength, puncture strength, environmental stress cracking resistance, and carbon black every 5 rolls. OIT is tested every 9 tons, and each formula is tested for 85℃ oven aging, 91 days OIT, 1600 hours of UV irradiation standard and high pressure OIT, and -70℃ low temperature impact embrittlement performance. We keep samples for each order, and each sample is kept for 5 years to ensure that the products have complete traceability.
