在机箱外壳表层，通常能看到一些划痕，划痕是外壳挤压成型环节较为常见的缺陷，对产品的质量的影响较大。若划痕在内部，多半是模具设备粘有杂质，若是划痕在外部，一般是因为在放料、运送过程中产生的，那怎样应对外壳表层的划痕呢?接下来小编为大家分享：

Scratches are usually seen on the surface of the case shell. Scratches are common defects in the shell extrusion process and have a great impact on product quality. If the scratches are inside, most of them are caused by impurities on the mold equipment. If the scratches are outside, they are generally caused during the placing and transportation process. How to deal with the scratches on the shell surface? Next, let's share:

1、在机箱外壳生产环节中应做到轻拿轻放，规避人为要素导致的刮伤。

1. In the production process of the case shell, it shall be handled with care to avoid scratches caused by human factors.

2、采用毡布或绝缘性布料来分离出来机箱外壳，降低二者之间的摩擦导致受损。

2. Use felt cloth or insulating cloth to separate the chassis shell, reducing the friction between them and causing damage.

3、公司企业务必保证模具修复的质量，机箱外壳模具设备应做到按期渗氮并认真落实渗氮工序。

3. The company must ensure the quality of mold repair. The case shell mold equipment should be nitrided on schedule and the nitriding process should be carefully implemented.

4、及时处理出料轨道、摆床等相关工作带，规避杂质干扰机箱外壳生产工艺的质量。

4. Timely handle the discharge track, swing bed and other relevant working belts to avoid impurities interfering with the quality of the production process of the chassis shell.

5、冲压模具运行带和冲压模具空刀需要加工平整光滑。

5. The running belt of the stamping die and the empty cutter of the stamping die need to be processed smoothly.

6、装模时需要仔细查看,避免有细微裂痕的模具设备被采用。

6. Careful inspection is required during mold installation to avoid the use of mold equipment with slight cracks.

7、放料时需要置放比产品软的隔条,输送,吊运均需平缓,仔细工作。

7. When placing materials, it is necessary to place spacer strips softer than the products, transport and lift them gently and carefully.
