(8) parts are installed;
Also comprise a framework preparatory technology step in step (3), (4), be about to steel framework and the fixing assembling of dies cavity less than the dies cavity size.
The concrete technological parameter of each processing step among the present invention is:
Be will be less than steel framework and the fixing assembling of dies cavity of dies cavity size 0.5%-6%.
Step (1) is that the addition of color masterbatch is the 0.5-5% of LLDPE and high density polyethylene (HDPE) total amount with granulation after the high density polyethylene (HDPE) of the LLDPE of 60-90 part, 10-40 part and a spot of color masterbatch blend.
The addition of hard acid ester salt is the 0.1-1 ‰ of the material total amount after the granulation in the step (1) in the step (2).
Step (2) is that the material after being mixed is ground into granularity is 60-90 purpose material powder.
Mould inner surface after the cleaning in the step (3) is smooth smooth.
The cooling of mould comprises air-cooled and water-cooled in the step (7), and the wherein air-cooled time is 15-25 minute, and the water-cooled time is 2-6 minute.
The shaping time of the external force typing in the step (7) was not less than 1 hour.
Also comprise the modification of mould between step (7) and the step (8), promptly remove the plastic flash of tank surface, make tank surface smooth smooth.
Add behind the quantitative molding powder matched moulds in the step (6) and mould is rotated heating in die cavity, the mold heated temperature is 295-305 ℃, and be 19-21 minute heat time heating time.
Substantive distinguishing features that the present invention is obtained and significant technological progress are:
This field airdrop equipment box outer case adopts has the non-toxic polyethylene material of excellent impact resistance energy and decay resistance in conjunction with the steel inner frame, utilize rotational molding technique to make, storage compartment had following characteristics after this technology can make moulding: load-bearing is big, intensity is high, good seal performance, waterproof, anti-dust, anti-pollution; Corrosion resistance and good, shock resistance are good, can be used as the parapack vanning and use.For not yielding in the intensity that guarantees casing and the use, satisfy that dress equipment in the storage compartment holds and, casing and steel inner frame are combined closely in one by roll moulding shaping technology as the effect of drawer support.The weight that the weight of content and pile produce is mainly born by the steel inner frame, has alleviated the supporting power of casing itself greatly.Adopt this special roll moulding shaping technology, the steel inner frame is wrapped in the inside by outer case in forming process, can not have influence on the outward appearance of product when increasing outer case intensity.
