What are the influencing factors of injection mold quality?

There are many factors affecting the quality of injection mold, and each factor is very important. The main factors are mold steel, structural design, mold processing, standard parts, flying die, polishing, mold assembly and cooling water, etc. The following Xiaobian will make a detailed description of the various influencing factors, I hope to help you.

1. Injection mold steel

The quality of the mold steel has a decisive impact on the injection mold, of course, it is not to say that the more expensive or mainly suitable, the cost and life need to be considered comprehensively. The simple truth is that the steel corresponding to the injection mold of 300,000 times, 500,000 times and 1 million times must be different; The appearance of injection mold treatment and injection molding products also have an impact on the mold steel.

2. Structural design of injection mold

The structural design of injection mold needs to consider the factors of cavity layout, determine the parting surface, determine the pouring system, choose the ejection way, determine the installation location of cooling or heating components, determine the thickness of the mold parts and dimensions. Reasonable injection mold structure can improve the service life of injection mold and ensure the rapid mass production of the mold.

3. Injection mold processing

The organization of mold process is particularly important. Reasonable process organization can speed up the production cycle, shorten the processing time, and save the cost. In order to reduce the mold manufacturing error, the machining precision should be improved first. With the use of CNC machine tools, this problem has been well controlled. In addition, in order to prevent the error caused by mold wear and deformation, the key parts such as cavity and core should be quenched when the machining accuracy is higher and the product output is larger. Processing errors will lead to mold welding. No matter how good the welding is, it is a loss for the injection mold and may affect the injection mold action and reduce the life of the mold.

4. Injection mold standard parts

The standard parts of injection mold do not directly participate in the molding, but they control the operation of the whole mold. A good standard part should have the characteristics of wear-resisting, high precision and not easy to deformation. Therefore, we must choose the injection mold with high cost performance when choosing, so that the service life of the mold can be extended.

5. Injection mold flying die

For complex injection molds, flying molds are very important, which plays a role in determining the quality of the molds. For example, the collision of auto parts molds is very complex, not only the shape of the fractal surface is irregular, but also often includes multiple slides and top blocks. The flying mold depends on the experience of the mold fitter. The seemingly simple work is the most technical work. Complex mold is mainly to see this kung fu.

6. Polishing of injection mold

Die polishing first plays a role in enhancing wear resistance and corrosion resistance to the surface of the die and prolonging the service life of the die. Die polishing can improve the precision of the die surface, prevent the generation of rough edges, reduce the occurrence of defective products, reduce the production cycle, improve processing efficiency, and save costs for enterprises.

7. Injection mold assembly

Injection mold assembly is like assembly machine, every part, every screw can not make mistakes, otherwise the result will be quite serious, light will lead to product shortcomings, affect production, heavy will completely harm the mold, the formation of waste. Die assembly is the last stage of die manufacturing process, the quality of assembly will affect the precision, life and function of each part of the die.

8. Injection mold cooling water

Because of the increase in prices and human compensation, in the mass production of products, not cut a second of injection cycle brought by the profit is impossible to imagine. If the cooling system design is not reasonable, it will result in a long production cycle and high cost. On the other hand, uneven cooling will also cause warping deformation of products due to thermal stress, thus affecting product quality.

Injection mold from raw materials, design, processing technology and other aspects will affect the final injection mold quality. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the service life is long, the rapid mass production and the finished product quality is excellent!
