井盖模具本身带有了自己独特的特点,可能是它的颜色,纯原料的通常为白色,如果掺有杂质,颜色会有变化,变得发黄。不要过于比较价格,买便宜的井盖模具不如买耐用的模具,这样可以减少产品不合格的风险。
The well cover mold itself has its own unique characteristics, which may be its color. The pure raw material is usually white. If it is mixed with impurities, the color will change and become yellow. Don't compare the price too much. It's better to buy a durable mold than a cheap one, which can reduce the risk of unqualified products.

粉碎回料做的模具,表面上会有很多黑点,浑浊不光亮,加力变形大。应从理念、技术、管理、制度等方面着手,升级应包括产品水平、技术水平、管理水平、营利水平及提高劳动生产率等多个方面。
There will be a lot of black spots on the surface of the mould made by crushing and returning materials, which is turbid and not bright, and has large force deformation. The upgrading should include product level, technical level, management level, profit level and labor productivity improvement.

****井盖模具的生产,需要注意每个细节的把握,从设计到选材,再由选材到加工,每个过程都是要仔细斟酌的。如果要提高模具质料的利用率,就要合理排样,淘汰工艺废料。
In the production of high-quality well cover mould, we need to pay attention to every detail, from design to material selection, and then from material selection to processing, every process should be carefully considered. If we want to improve the utilization rate of die material, we should arrange the sample reasonably and eliminate the process waste.

当塑料制件设计完成并选定所用材料后,就需要考虑是使用单型腔模具还是多型腔模具。浇注系统设计是否合理不仅对塑件性能、尺寸、结构、内外在质量等影响很大!
When the plastic part design is completed and the materials used are selected, it is necessary to consider whether to use single cavity mold or multi cavity mold. Whether the gating system design is reasonable not only has a great influence on the performance, size, structure, internal and external quality of plastic parts!
