Bozhou city cosmetic packing injection molding process

Bozhou city cosmetics packaging 2, mold temperature, injection molding process. Die temperature directly affect the cooling speed of melting and the degree of crystallinity, degree of crystallinity is different, the plastic pieces of different performance. Usually, the mould temperature control in 100 ~ 140 ℃, when molding thin-wall plastic parts, desirable small value; Thick wall molding plastic parts, desirable value. Steady purchase monitoring service to the society. Establish key industries recommended third party pollution enterprise system. The relevant person in charge of protection industry association, said in 2011, is engaged in the environmental protection product production in China has reached more than 4400 enterprises. However, in terms of guangxi, purchased from social monitoring the third-party service has been more common, but really the third party is a less pollution production enterprises. 3, drawing, burning on the lighter when a pull wire, wire pull long is not long, and then pull out the wire break, look at the middle of the breakpoints, silk is rolled into the small circle, the more volume of high melting point. As to strengthen the industrial support, macro strategic guidance and protection increasing, energy conservation and environmental protection industry has a broad development space and huge market increment, will focus on around water, air, soil niche. And monitoring data as the important basis of pollution licensing and tax collecting industrial enterprises exist subjective monitoring should be increased, industry development potential will be further release. 24 provinces, the provincial supervision plan. 24 provinces detailed rules for the implementation of ecological damage responsibility the government cadres, the rest of the province is also working on and ask for some advice. 'These files, compaction and departments at all levels of environmental responsibility. 'Ji-ning Chen said. Since then, and two levels of environmental protection at the provincial level supervision pattern has been initially formed. Enhance PET melting point 260 ℃, in order to prevent the nozzle blocking, power larger heater should be installed. In addition, the nozzle hole processed into figure - The inverse cone type 1, make the flow channel and the nozzle in the molten material can be easily cut. Based on forward-looking industry research institute published in the environmental protection industry development prospects and investment analysis report, according to data from 2013 after the 'atmosphere of article 10', 2014, 2015, the atmospheric pollution control growth of 18 respectively. 3%, 20. 8%, and the value was only about 5, 2013. 5%; Article 10 of 'water' in 2015, 2016, sewage treatment rate to 23. 3%. Perfume bottles of bladder is glass and PP. Lid inside outside pottery and porcelain, PP electrochemical aluminum, electrochemical aluminum, PP in ABS with a layer of PP sheet. 2. 3 blow [beforehand Environmental protection industry dynamic online 】 Environmental protection equipment market is constantly changing, the old business opportunities in the recession, new opportunities are constantly emerging. The personage inside course of study points out, is not difficult to do business, but there is no new formats. At present, a new round of environmental protection equipment manufacturing industry is releasing new business opportunities, equipment manufacturers is evidence of transforming into the overall solution provider, and built environmental protection equipment, intelligent, custom is the ram the cornerstone of smart power. 【 Environmental protection industry dynamic online 】 By ten 'soil' and so on good policy, the influence of the size of the soil repair industry is year after year. The industry is expected to soil repair industry scale is expected to reach 24 billion yuan in 2017, the whole industry will officially enter the outbreak period. Billions blue ocean market increasingly present soil repair industry will meet outbreak period of soil restoration industry buzz, still close to power a voice than in the industry, in 2017 China's soil repair industry scale will reach 24 billion yuan said. According to the requirements, the agricultural departments at various levels shall carry out the construction of ecological civilization of the major policy decisions, to carry out the spirit of no. 1 files, in accordance with the 'key breakthrough and comprehensive treatment, recycling and green development', closely around 'one of two minus three basic' goal, to further strengthen the pilot demonstration, monitoring and evaluation, policy establishment, resolutely play agricultural non-point source pollution to be completed. 9, open mould cost: manual mode is controlled in 2500 yuan, automatic mold is in commonly 4000 yuan a, 1 out of 4 or 1 to 8 to 16000 yuan - 32000 yuan, specific depending on the manufacturer conditions. 7, your order is commonly 3000 - 10000, can decide the color, usually do primary grinding and magnetic white is given priority to, or effect of pearl powder, bottle and cover with the same quality of the mother, but sometimes due to the bottle and cover with different material, the color has some difference. PET of vitrification transformation temperature about 165 ℃, the crystallization temperature range is 120 ~ 220 ℃. PET at high temperature has a strong hygroscopicity. For glass fiber enhanced PET material, also very easy to bending deformation at high temperature.
