Plastic mould manufacturing need to pay attention to what issues?

First of all, to look at the mold structure complicated degree and in general a set of plastic mold is a month or so. The time required to process complex mould is longer. Often open a plastic moulds, it is need to do a detailed review, after approval, can open mold, a plastic mold opening up is the need to test after test. Senior experts to share with you the following items in plastic injection mold manufacturing needs has the following kinds? Plastic mold factory small make up with you the following five important points. 1, mold cooling ( Water channels) With the product size, shape, plastic properties, the holding time and other related factors. 2, mold cavity roughness level to achieve 'mirror stage', otherwise difficult to mold release products, products damaged products during ejection force is too large. Positioning pin, and the roughness of the surface and other parts are standard rules. 3, the plastic mold should have enough stiffness, or deformation when clamping pressure maintaining, cause 'flash' to choose reasonable exhaust position and quantity control. Otherwise cause dissatisfaction with plastic injection products 'in'. 4, inject to choose reasonable and uniform material can reach each place ( The flow paths are equal) , and I will have enough reserves to ensure plastics supplies in the process of contraction. And the contraction coefficient of each type of material is different, mold should have reasonable shrinkage rate. 5, mold and injection molding machine fixed way to reasonable, reliable and firm, prevent the clamping deflection caused by the accident. And disassemble, and choose reasonable way of stripping, selecting rational plunger position and quantity, to ensure that products are not damaged during ejection. Is a collection of mold product development design, mold manufacturing, injection molding, fuel injection, silk screen one-stop service of plastic mold and plastic mold manufacturers.





plastic mould manufacturing has important influence on production


as to the reform and open policy, our country industrial enterprise unceasing development, after several years of development, our country has gradually become an industrial powerhouse. The development of the industry in China rapidly, it is a variety of factors. Which must use in the industrial development to the development of plastic mould manufacturing is one of the big industry rapid development boosters. Want to produce the products in industrial production, the vast majority of must have mould first, industrial production is usually through the use of the mould in the casting produced by industrial processes, even plastic products manufacturing is also inseparable from the mould, to produce qualified products, must want to have qualified mould first, each big enterprise products, if you have the ability to make your own mould themselves made, so that product quality is guaranteed, without the capacity of production mold, then use to buy mold, mold purchase must not neglect, this is related to the development of the enterprise in the future. Plastic injection mold manufacturing mold of choose and buy the first thing to note that hwang river strong toughness, toughness is very important to have the mold, in the process of production, most of the time the mold will be subjected to severe shock, and mould flexibility requirement is very high, if the mould flexibility is bad, in the process of production of products, very likely mould will be more than the impact force pulling broke, so you can't ignore. Wearability is mould must be purchased in addition, in the process of production, the mould friction is very much, can say every moment mold are affected by friction, the wear resistance of the mould is very strict, only wear a good mould, mould service life is long enough, because in the process of production, the frequency of the replacement of changshu plastic injection mould is too high to product influence is very big.
