1、濟(jì)南鋁板http://www.pdadn.com/對于因分流筋匯合不良造成的性能下降應(yīng)適當(dāng)增加筋與外表面、筋與筋匯流處的長度，或者增大壓縮比來解決，模頭壓力的改變可以通過改變模頭平直段長度來調(diào)整流料阻力；在模具設(shè)計階段可選擇不同的壓縮比來改變擠出壓力，但必須注意機(jī)頭壓縮比要與擠出機(jī)螺桿的壓縮比相適應(yīng);還可以通過改變配方，調(diào)整擠出工藝參數(shù)，增加多孔板來改變?nèi)垠w壓力的大小。
Jinan aluminum bars for convergence due to diversion caused by poor performance degradation should be appropriate to increase the length of the outer surface of tendons, muscle and tendon at the confluence of, or increase the compression ratio to solve, die pressure change can be achieved by changing the length of the straight sections of the die to adjust the flow resistance of the material; choose different compression ratio to change in the mold design stage extrusion pressure, but must pay attention to the nose and the compression ratio of the compression ratio of the extruder screw fit; can also change the recipe, adjust the extrusion process parameters, to change the size of the perforated plate increases the melt pressure.
　　
2、濟(jì)南鋁板口模出料不均勻，造成型材壁厚薄不一致，或者密實(shí)度不一致。這也就造成了型材兩個面之間的力學(xué)性能上的差別，至于壁薄等非標(biāo)型材這里就不再多說。
Jinan aluminum die discharge uneven, resulting in thin wall sections are inconsistent or inconsistent with the density. This also resulted in the difference between the mechanical properties of profiles on the two faces, as thin wall sections and other non-standard here is not to say any more.
　　
3、濟(jì)南鋁板口模截面設(shè)計不合理，尤其是內(nèi)筋的分布和交界面角度的處理，冷卻水溫往往沒有引起足夠的重視，冷卻水的作用是將型材拉伸的大分子鏈及時冷卻定型，達(dá)到使用目的。
Jinan aluminum die-sectional design is unreasonable, especially within the tendons of the distribution and processing interface point of view, the cooling water temperature is often not taken seriously enough, cooling water is the role of macromolecular chains stretch profiles timely cooling stereotypes, to use the purpose.
　　
4、、濟(jì)南鋁板http://www.pdadn.com/模頭壓力不足。模頭處壓力大小是直接受模具的壓縮比，特別是模具平直段的長度來決定的，模頭的壓縮比太小或平直段太短都會造成制品不致密，影響物理性能。
Jinan aluminum die pressure is insufficient. Pressure at the die size is directly affected by the compression ratio of the mold, particularly the length of the straight section of the mold to the decision, the compression ratio is too small or the die is too short straight sections are not dense products, affecting the physical properties caused.
