What are the three basic quality controls for long brass screws?

When the customer wants to place an order for long brass screws, we need to ensure that the screws produced meet the requirements and can be used by the customer. So how do we do that?

One is that the drawings are correct. Next production orders, be sure to check the dimensions and tolerances of customer’s requirement carefully, otherwise under the size wrong, then no matter how much control of production, the production of screw is not customer want, good cases, customers can accept and you can use, but poor circumstances, customers can’t use, you will need to manufacturers to production. This wastes time and increases costs.

Second, dimension measurement. No matter in the first stage or in the teeth rolling stage, when the semi-finished product is produced, we will measure it and measure it at regular intervals to make sure that the screw size in the production has not changed. Because sometimes the vibration of the machine will lead to the deviation of the mold position, leading to the change of the size of the screw.

Third, appearance. The appearance of the screw is also very important. If there is a defect on the surface of the long brass screws, you need to take a picture of the defective part to the customer. If the customer can accept it, then continue to produce.

If you also need to produce long brass screws, please come to consult the Shi Shi Tong screw manufacturer.
