We are a Chiller, Dehumidifying Drying Feeding Machine, Blow Machine manufacturer in China

Tongsheng Machinery Company is a professional Chinese manufacturer of industrial water chillers and blow molding machines. We specialize in the design and manufacture of a variety of products, including screw water chiller, mold temperature control unit, dehumidifier, dryer, feeder, hopper dryer, plastic blow molding machine, and more. Our products are utilized in a wide range of fields, including: plastics, medicine, food, chemicals, hardware, electronics, textiles, spray coating, and more.

Main Products
    1. Screw Water Chiller
    2. Screw Water ChillerMedium temperature screw water chiller can produce water from -5 to 45 centigrade. It adopts imported semi-closed imported semiclosed double screw compressor with economic unit. Medium temperature screw water chiller can also produce low temperature ethanediol solution from -5 to 45 centigrade or saline solution. It can work as the industrial cold source of chemical industry, medicine ...
    1. Industrial Cooling Chiller
    2. Industrial Cooling ChillerIndustrial cooling chiller integrates cooling chiller, freezing pump, cooling pump, expansion water tank, cushion water tank and measuring and controlling device into one machine. After testing, qualified chillers go into market. Our industrial cooling chiller is convenient to install and easy to operate. There is no need to have special machine workshops.
    1. Mold Temperature Control Unit
    2. Mold Temperature Control UnitOur mold temperature control unit uses hot medium liquid such as water or oil convertibly. Either water or oil can be used as a hot medium liquid according to the needs of mold forming temperature. Its high selectivity results in high economic efficiency.
      The flow of vertical pump can be always kept steady and its service life keeps long.
    1. Drying Feeding Machine (Two In One)
    2. Drying Feeding Machine (Two In One)Drying feeding machine is an energy saving two in one machine integrating functions of drying and feeding. It is automatic and easy to operate because it adopts PLC control system. Drying feeding machine adopts drying hopper, which preserves moisture. The loop of the feeding system is obturated, which prevents the raw material from being moisturized through contact with ambient air after drying.
    1. Plastic Blow Molding Machine
    2. Plastic Blow Molding MachineOur plastic blow molding machine adopts the whole oil line system and components in the professional blow molding machine from America Oil Pressure Company. Because our plastic blow molding machine selects good oil pump, oil valve, oil circuit board, proportional valves of pressure and flow, nitrogen energy storage system and unique oil-liquid filter system, the speed of oil line is fast and decreases steadily without shock.
    1. IML Robot (In Mold Labeling)
    2. IML Robot (In Mold Labeling)Double axes use servo motor and match high resolving coder. Double axes can offer exact orientation which reaches 0.05mm to meet different request even in the anomalistic mould cavity.
      IML robot can match the blow molding time and adjust the mold-in-label speed to make the movement much more steady and reduce the cost.

In order to improve the quality of our industrial chillers and hopper dryers, we've taken many measures. For example, we have established a quality control system to oversee each step of production, and we use internationally recognized components. Our compressors use screw in water chillers from Germany's Blitzer and the pneumatic components used in our plastic blow molding machines are from FESTO in Germany, and SMC in Japan. The use of these components helps ensure the performance and reliability of our products. We also continuously train our staff to improve their technical skills, and thus, to improve quality and enhance efficiency. As a result of our efforts, our products have been CE certified and our company has received the ISO9001 certificate. Therefore, you can feel totally secure in using our dehumidifiers, hopper dryers and plastic blow molding machines.

In addition to ensuring the quality of our products, we also focus on reducing costs, in order to provide our quality dryers and water cooled chillers at economical prices. When purchasing our raw materials, we sign a contract with steel suppliers and pick up our order from them, so as to avoid any middle-man expenses. More than 80% of our components are produced in our own factory, which reduces our component costs. We use internationally advanced processing equipment, such as Japanese four axle CNC lathes, fully automatic laser cutting machines, and automatic sheet metal spraying production lines, which contribute to increasing production efficiency and effectively reducing costs. All these factors enable us to offer high quality, competitively priced industrial cooling chillers and hopper dryers to customers worldwide.

We have a large production capacity of 6,000 industrial water chillers, 8,000 mold temperature control units, 3,000 dehumidifying, drying machines, 10,000 hopper dryers, and 220 blow molding machines every year. This results in our fast delivery of any order. We now have customers in America, Russia, India, Singapore, the Ukraine, Mexico, and Argentina. We welcome customers all over the globe to try our products. OEM service is also available.
