Plastic Melt Flow Indexer Plastic Melting Point Tester

     Liyi melt flow index extrusion plastometer applies to both molten high temperature of the PE, gather fang PSF, fluorine plastic, nylon engineering plastic, also suitable for polyethylene, polypropylene polystyrene, ABS resin, pom resins melting temperature lower plastic tests.

New desigh of Liyi melt flow index extrusion plastometer:

How it works:
     Melt flow rate meter is in the specified temperature conditions, with high-temperature furnace to melt the state of the measured object. The molten state of the measured object, the required weight load by gravity out of a certain diameter hole in the test. Plastics in industrial enterprises and scientific research units of production, often with "melt (mass) flow rate" to represent the polymer material in the molten state of fluidity, viscosity and other physical properties. Melt flow rate refers to the extrudate, the average quality of the sample paragraphs are translated into 10 minutes of extrusion volume. Melt (mass) flow rate expressed by MFR, unit: g / 10 minutes (g / min)
Formula: MFR (θ, mnom) = tref × m / t = 600 × m / t (g/10min)
Where: θ - test temperature
mnom - Nominal Load Kg
m - the average quality of cut g
tref - reference time (10min): 600
t - cut off time interval unit: seconds.

Example:
   A set of plastic samples, a cut every 30 seconds, the quality of the results section: 0.081 g, 0.086 g, 0.081 grams, 0.089 grams, 0.082 grams.
   Cut the average quality m = (0.081 +0.086 +0.081 +0.089 +0.082) ÷ 5 = 0.0838 ≈ 0.084 (g)
   Into the formula: MFR = 600 × 0.084/30 = 1.680 (g / 10 min)

     Dongguan Liyi Environmental Technology Co., Ltd is a high technology supported production-oriented enterprise who specializes in developing, manufacturing, marketing all kinds of environmental equipment. Our company has advanced technology, experienced technical management personnel and efficient professional service staffs, fine quality management and perfect after-sales service system.

     Our company mainly produce simulated environmental tester, plastic and rubber tester etc. on all kinds of materials testing industries. The production base is located in the country’s manufacturing center Dongguan, Guangdong province, China. In order to service our customers better in terms of reducing costs and early delivery, in 2005 we had set up an office in Kunshan, Jiangsu province for Eastern China marketing and servicing.

     Liyi deals with customers from more than 150 countries and regions. Meanwhile, we are committed to cooperate with different dealers in different countries and regions in order to offer better service. Our mission is to help every customers establish testing labs to ensure the quality of their products.

     Our company will continue to develop, innovate and keep faith. We combine with the international testing standards and the specific demands of customers that may establish a new banner in Chinese testing industry.

3)Production and delivery process:

      We will produce the machines according to confirmed PO requirements. Offering photoes to show production process. 

      After finish production, offer photoes to customer to confirm again with the machine. Then do own factory calibration or third party calibration(as customer requirements). Check and test all the details and then arrange packing.

      Deliver the products in confirmed shipping time and inform customer.

4)Installation and after sale service:

      Defines installing those products in the field and providing after-sales support.
