耐油橡胶密封件O形圈品种繁多,用途甚广。其中某些品种用量并不多,因此,采用一般的模具制作便显得造价昂贵。例如,定制10个外径φ150毫米、截面直径φ5.7毫米的O形圈就需300元,而外径φ200毫米的则需400元等等。为此,我厂经过多次试验,采用圆条橡胶粘合法自制O形圈,所制O形圈质量完全符合要求,现介绍如下: 1.粘接方法将所需规格的硅橡胶圆条按所需长度(长度=O形圈中径展开长+2个线径长)把两端 Oil-resistant rubber seals O-rings wide range of uses. Some of these types of dosage is not much, therefore, using the general mold making it appears costly. For example, custom 10 Outer Diameter φ150 mm, cross-sectional diameter φ5.7 mm O-ring to be 300 yuan, while the outer diameter φ200 mm will need 400 yuan and so on. To this end, I plant after many tests, using round rubber adhesive O-ring self-made, the quality of O-rings made in full compliance with the requirements are as follows: 1. Bonding method The required specifications of the silicone rubber round Press both ends of the required length (length = O-ring middle diameter extension length +2 diameter long)
