1. Процесс рисования
(1) Process flow
The drawing process is to heat the plastic particles to a molten state, выдавить их, а затем растянуть, дуть, шапка и другие процессы. Can produce high quality, high transparency thermos cup.
(2) Характеристики
The insulated cup made by drawing process has thin wall, light weight, high strength, good transparency, and is not easy to deform during use.
2. Water rise process
(1) Process flow
The water swelling process is to first heat the plastic particles to the flowing state, and then inject them into the mold, and then form them after cooling by high pressure water vapor, and then carry out polishing, inspection, уборка, packaging and other processes. Thermos cups with thick walls can be produced.
(2) Характеристики
The insulated cup made by the water rising process has thick walls, heavy weight, low strength, and easy deformation during use, but because of its low production cost, the price is cheaper.
3. Process selection
Both processes have advantages and disadvantages, and need to be selected according to needs. The drawing process is suitable for the production of high quality, high transparency of the thermos cup, suitable for the manual process is complicated, difficult to form the product; The water swelling process is suitable for the production of low cost and cheaper thermal cup, and is suitable for the products with low molding parameters.
Суммируя, the thermos cup drawing process and water swelling process have advantages and disadvantages, and need to be selected according to the characteristics and cost of the product.
