Mold making is a complex process, from the design, processing, assembly, commissioning and other steps to the final actual use. In the entire life cycle, the factors affecting the quality of the mold are mainly the following 10 aspects.<\/p>\n

1. Mold steel<\/strong>
\nInventory 10 major factors that affect the quality of injection molds! The old mechanics are all in the collection
\nSteel is the decisive factor for mold quality, and choosing reasonable steel is the top priority. The criteria for selecting steel are:
\n\u2460Requirements for injection molding<\/a> materials
\nDifferent plastics must use different steels, such as high polishing requirements, corrosion resistance requirements, etc .
\n\u2461 Price
\nThe properties of the steel can be used, not the more expensive the better; considering the cost of the mold, the mold steel should use the material corresponding to the life of the mold to avoid unnecessary waste; generally the life of P20 material is about 300,000; 2738 material is 500,000 is no problem, H13 \/ 2344 is usually more than 800,000-1 million, you can choose according to the situation;
\n\u2462 surface treatment
\nThe surface treatment of the mold is also very important. Nitriding can enhance the surface hardness of the steel and effectively extend the life of the mold; electroplating can effectively modify the steel of the mold. For some plastic parts that require high brightness and corrosion resistance, electroplating can be used to enhance and improve the performance of the steel.<\/p>\n

2. Structural design<\/strong>
\nThe mature mold structure not only takes into account product material properties, shrinkage, molding temperature, elastic tensile deformation coefficient, etc., but also takes into account the cooling water path and the speed of opening and closing the mold. Reasonable mold structure can effectively extend the life of the mold and ensure the smooth production of the mold, improve efficiency and reduce costs.<\/p>\n

3. Mold processing<\/strong>
\nInventory 10 major factors that affect the quality of injection molds! The old mechanics are all in the collection. If a workman wants to be good, he must first sharpen his weapon. The arrangement of the mold process is particularly important. A reasonable process arrangement can speed up the production cycle, shorten the processing time, and effectively save costs. And more importantly, accurate and reasonable processing can ensure the stability and prolong the life of the mold in the production process. Some processing errors can lead to mold welding, no matter how good the welding is, it is a loss for the mold; in addition, poor processing may affect the mold action, reduce the mold life, and cause the mold to crack during the production process It even broke.<\/p>\n

4. Standard parts<\/strong>
\nThe lowest wooden stick determines the bucket capacity. Everyone understands this reason, but often they don’t notice when doing it. The same is true for the mold. Although the standard part does not directly participate in the molding, it controls the operation of the entire mold. Good standard parts should be able to wear-resistant, hard enough, high precision, and should not be deformed. The difference between standard parts of different brands is very big, so don’t blindly bargain when making molds<\/a>, kill them, and your molds will go from Mercedes-Benz to the public.<\/p>\n

5. Touch (flying model)<\/strong>
\nFor the experience of relying on the mold fitter, seemingly simple work is the most technical work. The main focus of complex molds is this effort. The flat mold is the simplest, as long as the fractal surface is not flashed, it is basically OK. Auto parts molds are very troublesome, not only the fractal surface is relatively irregular, but often includes multiple sliders and top blocks. At the same time, other problems of the mold can be improved and perfected through collision, so it is a comprehensive work.<\/p>\n","protected":false},"excerpt":{"rendered":"
