Production technology and advantages and disadvantages of plastic inspection well

1、焊接工艺

1. Welding process

优点：生产固定设备投资少，只要具备相应埋地管道与焊接设备即可。

Advantages: the production of fixed equipment investment is small, as long as the corresponding buried pipeline and welding equipment can be.

缺点：a、带有流槽的检查井不能焊接；b、生产效率低，大口径的井每天甚至只能生产几个；c、焊接部分需要正反面焊接，焊接部分质量可靠度受人形骨架模具 保定代理记账 保定道闸 防撞护栏模具 风电基础模具 保定空压机 北京真空泵工焊接制约较难保证。

Shortcomings: the A, the inspection well with the groove can not be welded; B, the production efficiency is low,lujianshi.75ix.com liujiaomoju.75ix.comhuafenchim.75ix.com gelidun.75ix.com yadingmoju.75ix.cn liushui.75ix.cn the large caliber well can even produce only a few, C, the welding part needs the reverse side welding, the welding part quality reliability is difficult to guarantee by the manual welding.

2、滚塑工艺

2. Rolling process

优点：能生产制作较大口径的检查井、固定资产投入少

Advantages: it can produce large caliber inspection wells and less investment in fixed assets.

缺点：生产的产品壁厚不均匀，密度较低，强度低

Disadvantages: uneven wall thickness, low density and low strength.

对于复杂型腔的制品不易成型，生产效率低，不能满足短期内大批量供货，目前市场上滚塑井底部缺少平衡支撑。

For the complex cavity of the product is not easy to shape, low production efficiency, can not meet the short-term supply of large quantities of rolling wells in the market at present lack of balanced support.

3、注塑工艺

3. Injection molding process

优点：生产效率高，可满足市场大批量供货、综合成本低，长期考虑性价比最高、制品密实度大，单位面积承压力大、可生产检查井底部具有平衡的支撑，便于安装、规格尺寸精度有保证。

Advantages: high production efficiency, can meet the market large quantities of supply, low comprehensive cost, long-term consideration of the highest cost performance, high density of products, high pressure per unit area, can be produced to check the bottom of the well has a balanced support, easy to install, specification and size accuracy guarantee.

缺点：一次性投入大。

Shortcomings: big investment in one time.
