What is the process of machining irregular parts? How to prevent corrosion and conduct acceptance inspection? Let's talk about the machining of irregular parts.


   Custom-shaped part processing With the rapid development of the machinery industry, the fastener industry has become more prevalent, and custom-shaped fasteners are also becoming increasingly popular. For some entrepreneurs, special occasions require special fasteners, which demonstrates the importance of custom-shaped fasteners. Producing custom-shaped fasteners is crucial, but before manufacturing, manufacturers need to adhere to customer requirements and special specifications. Under what circumstances are custom-shaped fasteners needed? Let's discuss custom-shaped part processing below.

  Fasteners are of two types: standard fasteners and non-standard fasteners. Non-standard fasteners are also called custom-shaped parts.

  For example, nuts, which are common in our daily lives, can be tightened together with bolts to secure an object or part. Nuts and bolts are used in machinery manufacturing, daily life, or other parts. They are indispensable accessories, and nuts come in a wide variety. Nuts can be classified into high-strength, stainless steel, carbon steel, and plastic steel according to their material. According to the nature of the nut, there are standard nuts and non-standard nuts. Standard nuts are internationally standardized models, usually called ordinary bolts. Non-standard nuts are special nuts with many uses and types outside the national standard models. When we cannot find the corresponding model in ordinary nuts for the nuts used in our daily lives, special nuts are used for tightening. Manufacturers need to meet customer needs in manufacturing parts with special shapes.

  So how to prevent corrosion of custom-shaped parts? Custom-shaped part processing suggests this:

  1. When electroplating custom-shaped parts, their corrosion resistance directly depends on the thickness of the plating layer, so the requirements for the usage scenario are very strict. Therefore, the electroplating layer needs to be thicker to achieve good corrosion resistance and better solve problems during use.

  2. For custom-shaped parts, a better method is chromate conversion treatment. Simply put, chromate conversion treatment is performed on the electroplated custom-shaped parts again, which can increase the corrosion resistance of zinc and the plating layer.

  3. During use, when electroplated custom-shaped parts come into contact with metal products or raw materials, corrosion resistance will be affected again due to stability and environmental reasons. Therefore, extra care must be taken during use. Due to special usage scenarios, various reasons can accelerate corrosion.

  Custom-shaped part processing briefly describes the acceptance procedure for custom-shaped parts below:

  We need to check the packaging to see if the packaging box has strong moisture-proof performance. The box should be packaged with custom-shaped parts and connecting components. Different custom-shaped parts cannot be mixed according to regulations. The weight of each box should not exceed 40 kilograms. However, how to package it inside the box is entirely up to the manufacturer. The outer packaging of the box should indicate the manufacturer's name, product name, standard number, product specification number, batch number, and strictly indicate the gross weight, etc. When inspecting goods, check the product quality inspection report and factory certificate provided by the manufacturer in batches.

  Inspection should be carried out in batches during production, and the performance grade and material of the custom-shaped parts should be the same batch number as the furnace number and thread specification length. The same batch number is used for bolt cutting, heat treatment, and surface treatment.

  It should be noted that when supplying custom-shaped connecting components, the large quantity of torque coefficient supplied should be 3000 sets.
