  • The Plastic Injection Machine machine industry is expected to become international

    August 16, 2017

    Plastic Injection Machine are widely used in the manufacturing sector, in the packaging, home, home appliances, automobiles, 3C and other manufacturing parts of the production process are very important. Due to the diversity of requirements, the performance requirements of injection molding machines are also different, on the other hand, modern servo motor and integrated electronics technology continues to mature, led the continuous improvement of the technical level of injection molding machine. Continued technological progress is a necessary condition for enterprises to maintain their market competitiveness for a long time. Injection molding machine industry demand in 2000 since the sales growth rate of more than 10%. From the industry as a whole, a single industry impact on the demand for injection molding machine is limited, the demand for injection molding machine has a significant impact on manufacturing investment. Since the second half of 2016, manufacturing investment growth began to pick up, injection molding machine as an important spare parts manufacturing equipment, manufacturing investment rebound directly led to industry demand growth. Future Outlook: Demand for manufacturing industry with toughness, some sub-sectors demand more Aspect In the future demand continuity judgment, we believe that manufacturing demand is expected to be updated demand and manufacturing investment in these two aspects of support. One is to update the demand and capacity to upgrade the role of the backing; the second is a real improvement in manufacturing investment, corporate capital spending to expand. Micro, 3C, home appliances, automobiles and other downstream sub-industry is expected to continue to maintain strong demand. At present, many brands of domestic injection molding machine industry, Japanese companies, European and American enterprises and domestic brands are in the industry occupy a place, such as Sumitomo Demag, Mi

  • How to choose a water chiller for injection molding machine

    May 10, 2017

    The vertical and horizontal injection modling machine working under normal ambient temperature, the condensing temperature is below 35℃ for water cooled chiller, the condensing temperature is below 45℃ for air cooled chiller. A: First way of choosing water chiller 1HP water cooled chiller is suitable to 80 tons injection molding machine, chilled water temperature range 5-10℃. 1HP water cooled chiller is suitable to 100 tons injection molding machine, chilled water temperature range 10-15℃. 1HP water cooled chiller is suitable to 120 tons injection molding machine, chilled water temperature range 15-20℃. Normally, when choose water chiller machine, we suggest selectivity coefficient 0.8, i.e. 1HP water cooled chiller is suitable to 80x0.8=64 tons injection molding machine, chilled water temperature range 5-10℃. B: Second way of choosing water chiller 1HP water cooled chiller is suitable toinjection molding machine with shot weight 10QZ, chilled water temperature range 5-10℃. Shot weight 1QZ=28.5g C:1HP water cooled chiller need a 1.2 tons cooling tower to remove the condenser heat.

  • Haitian Injection Machine VS Rainbow Injection Machine, which one is better?

    March 29, 2016

    "How is Rainbow plastic injection molding machine? Rainbow better or Haitian better?", some of our customers asks us like this. Thats's really an interesting question, right? As all we know, China Haitian is one of the most famous manufacturer of plastic injection molding machine in the world, they sell many machine every year. We admit Haitian machine is good, but we don't think Haitian machine is the best, because Rainbow has his own market and customers. Why these customes choose Ranibow not Haitian, because we can provide same good machiine quality, and the most inportant point is that our price is much cheaper than Haitian. When buy machine or other goods, quality is the most important point and price is the most sensative point, but we think quality/price ratio is the best judgement to help you make decision. We believe you will choose Rainbow after compare everything like machine quality, price, componets, performance, etc. Rainbow provide you prefessional injection molding solution!
