The comparative advantage of China's mold in the international mold market still exists, and the domestic mold market is expected to continue to be optimistic. The development of the mold hardware industry is showing a general trend. Among them, mold hardware is becoming larger and larger, which is also a trend of prohibited words in the future. Why is this?
First of all, this is due to high production efficiency requirements. In order to improve production efficiency, the "one-mold multi-cavity" technology is waiting for more and more widespread applications. Obviously, the same injection molding process can produce multiple products at the same time, and the production efficiency is naturally doubled. Another reason is that the parts are becoming larger and larger, which directly leads to the need for larger molds.
With the increasing size of molds and parts, we are all troubled by how to meet the increasingly high surface accuracy requirements of large molds and parts? How to extend the service life of these large molds and parts, while taking into account wear resistance , Anti-corrosion, high hardness, etc. comprehensive requirements?
To solve these problems caused by the increasing size of molds and parts, in fact, we must pay attention to the design and materials from the beginning. However, many people ignore the last process in the processing and manufacturing of these large molds and parts-surface treatment. In fact, in the process of surface treatment, if you can choose a qualified electroplating service provider and choose the correct electroplating type, then the wear resistance, corrosion resistance, and high hardness of large molds and parts can easily be satisfied. .

The actual parameters obtained by any machining method will not be absolutely correct. From the perspective of the function of the part, as long as the machining error is within the tolerance range required by the part drawing, it is considered that the machining accuracy is guaranteed.
Machining accuracy is the degree of conformity between the three geometric parameters of the actual size, shape, and position of the surface of the processed part and the ideal geometric parameters required by the drawing. Ideal geometric parameters are uniform in terms of size; in terms of surface geometry, they are absolute circles, cylinders, planes, cones, straight lines, etc.; in terms of mutual positions between surfaces, they are absolutely parallel. , Vertical, coaxial, symmetrical, etc. The deviation of the actual geometric parameters of the part from the ideal geometric parameters is called the machining error.
Machining accuracy and machining error are both terms used to evaluate the geometric parameters of the machined surface. Machining accuracy is measured by tolerance grade, the smaller the grade value, the higher the accuracy; the processing error is expressed by the numerical value, the larger the numerical value, the greater the error. High machining accuracy means small machining error, and vice versa.
