PE管挤出模具
（螺旋式模具）螺旋式模具特点：熔体流动速度达到预期的力学均匀性，热均匀性。
1.螺旋体能在内层、中层、外层管材生产上使用，也可以用于不同压力等级的管材；
2.压力消耗少，产量高；
3.无须芯棒支架，使生产中长发生的流纹消失；
4.结构紧凑，连接合理，更换方便；
5.采用优质模具钢制造；
6.直径200以上口径均设计有内部加热恒温装置（内部加热器和模温机）
7.流道镀铬并抛光让用户得到较佳的制品外管。
8.配有模具移动小车，电动90°翻转使更换模具规格更为方便快捷。目前中国的管材市场，塑料管道正在稳步发展，PE管、PP-R管、UPVC管都占有一席之地，其中PE管强劲的发展势头较为令人瞩目。
PE管的使用领域广泛。其中给水管和燃气管是其中较大的应用市场。可靠的质量、合理的价格，为我公司赢得了良好的口碑。在生产PE管模具上，我公司有着丰富的生产经验。PE管的发展也必然对模具提出了更高的要求。
PE pipe mould
In China’s pipe maker, at present plastic pipes are developing stably. PE pipes, PP-R pipes and UPVC pipes have their own shares, in which the strong development tred of PE pipes is mot eye-catching.PE pipes have extensive application fields, in which water supply pipes and gas pipes are the two largest application markets.
Reliable quality and reasonable price win good comments for us. We have rich experience in making molds for PE pipes. The development of PE pipes is certain to be strict with moulds.
Character of Spiral type mould:
1.	Flow speed of melt is reached to.
2.	Spiral distributo can be used in the production of inner, middle and outer layer,and for producing pipe for different pressure classes.
3.	Low pressere, high extrusion capacity.
4.	No core mold bracker, so no flow mark lefe.
5.	Compact stucture, reasonable connection, convenient to change.
6.	Mode of excellent mould steel.
Composite molds
The PE composite mould made by us is of three-layer spiral distribution structure.
According to the requirements of products, we can co-extrude with two or three extruders.
Co-extusion by three extruder: for producing three-color pipes and sandwich pipes(such as PPR glass fiber nano bactrial-resistant pipes)
Co-extrusion by two extruders:for producing three-layer PE sandwich pipes and glass fiber PPR pipes. The proportion of inner side to the outside can be regulated by a screw. Close the screw in the inner-layer flow channel can produce two-layer products such as silicon core pipes and PPR nano bactreial-resistant pipes.
