180°分型O形圈主要用在静密封上。这种O形圈硫化模具同45°分型O形圈硫化模具相比较,在加工、检测上都比较方便,因此成本较低。如果模具有较高的制造精度,完全可以代替45°分型的O形圈应用在动密封上。这种模具有的厂家采用坐标镗床进行加工,精度固然较高,但加工比较麻烦,机床加工费用大,成本较高。我们是用普通车床加工,成本较低,只要采取必要措施,其精度不低于 180 ° type O-ring is mainly used in the static seal. This O-ring vulcanized mold with 45 ° O-ring type curing sub-model compared to the processing, testing are more convenient, so the cost is lower. If the mold has a higher manufacturing precision, can replace the 45 ° O-ring type applied to the dynamic seal. This mold some manufacturers use coordinate boring machine for processing, the accuracy is higher, but the processing is too much trouble, machine tool processing costs, higher cost. We are using ordinary lathe machining, lower cost, as long as necessary measures taken, its accuracy not less than
