Main plastic forming technique of inspection Wells are welding, plastic, injection molding, three ways of the three methods have advantages and disadvantages, so why would choose Shanghai, well injection molding process?
Welding process
Advantage: the production of fixed equipment only need a little bit of investment, have buried pipes and welding equipment can be completed
Disadvantages: if the plastic welding inspection shaft with a chute is not; The production efficiency is very low, large diameter inspection Wells can produce several commonly; Welding parts of both sides need to welding, welding parts it is hard to guarantee reliable quality is restricted by manual welding.
Rotomolding technology
Advantages: can produce larger wellhead inspection shaft; Fixed investment is less.
Faults: to produce plastic inspection shaft wall thickness is not very uniform, low density, low strength; For complex cavity shape of products is not easy; The production efficiency is very low, in the short term can't mass production; Rotomolding well on the market at present a lack of balance.
Injection molding process
Advantages: high efficiency, can satisfy the huge market supply; Low comprehensive cost, consider the price for a long time; Density of the finished product is very big, strong pressure per unit area; Can produce complex flow tank inspection Wells; Can produce a balance inspection shaft support, easy to install; Size precision is guaranteed.
Disadvantages: to invest.
Comparing the three plastic molding process of inspection Wells, we see not hard, why Shanghai optimal well with injection molding process, although the prophase investment will be higher, but for now this is a huge market, injection molding process is very obvious advantages.
