Charge Standard for Plastic Shell Manufacturers of LED Driving Power Supply in Shanghai

     上海新云塑料制品有限公司是一家专业生产塑料制品的民营企业,是集模具开发、注塑加工、塑料制品为一体的塑料配套产品的解决方案供应商,位于上海市松江区四岗镇。. It is located in the southwest of Songjiang District, Shanghai. It is adjacent to G60 (former A8 Shanghai-Hangzhou Expressway) G1501 (former A30 and three expressways). 交通便利,物流条件优越。
    
     上海LED驱动电源塑料外壳厂家收费标准厂家指出,模具制作是指加工成型和落料工具,除剪切和模切模外。通常模具由上下模组成。计算公式也根据冷却时间的定义而变化。基体上的注射成型是指在金属板的局部表面插入零件的方法。
    
     熟悉塑料零件的几何结构,明确使用要求,除了解图纸外,还应在头脑中建立清晰的三维图像,同时充分了解塑料零件的使用,塑料零件各部分的作用,明确塑料收缩、透明、尺寸公差、表面粗糙度和允许变形范围等问题,检查塑料件的结构工艺性,确认塑料件的细节是否符合注塑工艺条件。The high quality mould depends not only on the correctness of the structure of the mould, but also on whether the structure of the plastic parts can meet the requirements of the forming process.Only by mastering these steps skillfully can we avoid unexpected things in the process of injection mold design and ensure that the overall progress of inj型材模具产品不受注塑模具的影响。
    
     Shanghai LED drive power supply plastic shell manufacturers charge standard will be placed between the upper and lower dies, under the action of the press to achieve material forming, when the press opens, will be determined by the shape of the die workpiece or removal of the corresponding waste.Workpieces as small as electronic connectors and as large as automotive dashboards can be molded.
    
     After quenching and tempering, the die is usually grinded to reduce the surface roughness, because the grinding speed is too high, the grinding wheel size is too fine or the cooling conditions are poor, which causes the surface of the die to be overheated, which makes up some changes in the microstructure, or causes the appearance to soften, the hardness to decline, or the appearance of high residual tensile stress, which will reduce the die.The grinding cracks can be effectively avoided by choosing proper grinding parameters to reduce some heating and stress removal after grinding.There are many ways to avoid grinding overheating and grinding cracks, such as choosing coarse-grained grinding wheels with strong cutting force or grinding wheels with poor cohesion, reducing grinding feed of dies, choosing appropriate coolants, and eliminating grinding stress by tempering at 250-300 C after grinding.
