Processing technology of plastic inspection well
welding technology
Advantages: only a little investment is needed for the production of fixed equipment, with corresponding burial The Conduit And welding equipment
Disadvantages: If the plastic manhole http://www.zbpeg.com/ If there is a launder, welding is not allowed; The production efficiency is very low. Generally, large caliber inspection wells can only produce a few; The welded parts need to be welded on both sides, and the quality of the welded parts is reliable, which is restricted by manual welding It's hard to get a guarantee.
Rotational molding process
Advantages: it can produce inspection wells with large wellhead; Less fixed investment.
Disadvantages: the wall thickness of the produced plastic inspection well is not very uniform, the density is low, and the strength is low; It is not easy to form products with complex cavities; The production efficiency is very low, and mass production cannot be carried out in a short time; At present, there is a lack of balance support for the rotational well seat in the market Brace.
Injection molding process
Advantages: high production efficiency, which can meet the huge market supply; The comprehensive cost is low, and the long-term cost performance ratio is high; The density of finished products is very high, and the pressure bearing capacity per unit area is strong; Able to produce complex launder manhole; It can produce Inspection well for easy installation; The specification and dimension accuracy are guaranteed.
Disadvantages: large one-time investment. http://www.sdpegj.com/
