The further optimization of the current product structure is an important strategic shift for fastener companies. The low-carbon steel hexagonal nuts are gradually transformed into medium-carbon steel-based A194 2H-grade nuts, which will allow the company to gain more profitable space. For this reason, the quality has higher requirements on the production process and preparation of nuts. Facing such structural adjustments, it is necessary to start to formulate quality control programs and inspection specifications from the following aspects.
First, prepare before volume;
The second spot check in output;
Third, the final inspection after output.
First of all, preparations before production include: related personnel, equipment conditions, mold equipment, manufacturing process, raw materials, and so on.
However, the first item involves three major aspects: a, mold preparation; b, inspection methods; c, the control of the production process, resulting in higher requirements for these parts.
First look at mold preparation: from order to mold planning to production, perfect mold equipment is needed. It can be considered that the production ahead of the supply is satisfactory, and production is not delayed by the mold. This requires sufficient inventory to ensure this cycle. Usually about 20 to 25 days.
Second inspection method: In this link, we should pay attention to the detection of tools and methods. The most basic detection tools we know are vernier calipers, micrometers, thread gauges, Rockwell hardness machines, tensile testing machines, etc., most of them Enterprises have always chosen the methods of on-site inspection and sampling.
The final is the control of the output process: including appearance, method specifications, thread stop, mechanical properties. In order to ensure the use of the nut, we first control the first three items, and the appearance can be completed by visual inspection. In order to control the accuracy of the internal thread, it is necessary to make a set of inner diameter lubrication plug gauges, and a set of inspectors and operators can easily check the standard nut; other rely on the precision of the production of the mold and the debugging of the pressure in the production process ; The requirements for mechanical properties depend on raw materials and heat treatment to complete. But we often overlook the most important factor-the cultivation of the nature of workers.
Everyone is a single person and has his own characteristics and habits. The essence of cultivation includes: the principles of handling things, the environment in which the goods are produced, the ideological education of the operators, the technical proficiency of the operators, and the personal cultivation of the staff and so on. For example, the hexagon nuts we produced are the same, with six corners and six edges, and each edge is an important element.
Let our fastener companies not only produce high-quality hexagon nuts, but also cultivate a group of talents. This is where the vitality of fastener companies lies and where quality advances.
