Anonymous users2024-02-16The process of making a two-color mold includes the following steps:
1.Analysis of plastic products: Before the mold design, the designer should fully analyze and study whether the plastic products conform to the principle of injection molding processing, and need to negotiate carefully with the designers of plastic products, and a consensus has been reached.
This includes the necessary research and discussion on the shape, dimensional accuracy and appearance requirements of the product, and try to avoid unnecessary complexity in two-color injection molding.
2.Mold structure design: a set of high-quality molds, not only need to have good processing equipment and experienced processing masters, in addition to a very important factor is to have a good mold design, especially for complex molds, the quality of mold design accounts for more than 80% of the quality of the mold.
3.Selection of mold materials and standard parts: In the selection of mold materials, in addition to considering the accuracy and quality of the product, it is also necessary to give the correct choice in combination with the actual processing and heat treatment capabilities of the mold factory.
In addition, in order to shorten the manufacturing cycle, existing standard parts are used as much as possible.
4.Part processing and mold assembly: In addition to giving the best structure and reasonable tolerance in the design of the precision of injection molds, part processing and mold assembly are crucial.
Therefore, the choice of processing accuracy and processing method occupies an absolute dominant position in two-color injection molding.
5.Action detection before mold trial: do a good job of action detection before mold trial, do not miss or install the machine by mistake, mold installation error will lead to the failure of more than two sets of mold cores.
6.Mold mounting: Before mold mounting, remove all locking screws and fill the mold at one time. The mold must not be adjusted to high pressure on the reverse operating side, otherwise the moving platen will damage the machine due to uneven force.
7.Debugging: After the mold is assembled, debugging is carried out to ensure the normal operation of the mold.

2. Take a group of male models and the secondary female model to coincide, so that the Dan is completely complete (the male model is painted with Dan, and the secondary female model is repaired).
3. Do a good job of action detection before mold trial, do not miss installation, wrong installation on the machine (wrong mold installation will lead to more than 2 groups of mold kernel invalidation).
4. Frame formwork: Remove all the clamping screws before the frame formwork, and the high pressure on the mold should not be adjusted on the full mold and the reverse operation side first, otherwise the moving template will damage the machine due to uneven force; The clamping screws can be tightened only after all the clamping screws are loaded by hand, and the male mold rotates 180 degrees after the mold is opened; Loading the secondary master mold is based on the primary male mold; Finally, the male mold loaded with the secondary is based on the secondary female mold; After two sets of mold frame molds are ok; Adjust the mold.

Anonymous users2024-02-14The advantages of two-color molding molds are as follows:
1. The product has high precision and stable quality.
2. Good structural strength and durability.
3. The matching gap is small and the appearance is good.
4. Greatly reduce the cost.
Two-color mold: A mold in which two plastic materials are injected on the same injection molding machine and molded twice, but the product is molded only once. Generally, this molding process is also called two-component injection molding, which is usually completed by a set of molds and requires a special two-component injection molding machine.
Two-color mold is becoming more and more popular in the market at present, and this process can make the appearance of the product more beautiful, easy to change the color without spraying, but the cost is expensive, and the technical requirements are high.

Anonymous users2024-02-13Two-color injection mold molding is mainly made of two-color injection mold products by using two barrels of double-shot molding machine with two sets of molds in order to form two-color injection mold products. Compared with traditional injection molding, the two-component co-injection molding process has the following advantages:1
Two-component injection molds: The core material can use a low viscosity material to reduce the injection pressure. 2.
Color injection mold: From the consideration of environmental protection, the core material can use the best secondary material. 3.
Depending on the characteristics of use, for example, soft materials are used for thick finished skin materials, hard materials are used for core materials, or foamed plastics can be used for core materials to reduce weight. 4.Lower quality core material is used to reduce costs.
5.The skin material or core material can be used to increase the product performance with expensive and special surface properties, such as anti-electromagnetic interference, high conductivity and other materials. 6.
The combination of skin and core material can reduce the residual stress of the molded product, increase the mechanical strength or surface properties of the product. 7.Such as marbled products.
The characteristics and applications of color injection molding and two-material co-injection molding can be seen that there is a trend of gradually replacing the traditional injection molding process in the future. The innovative injection molding technology not only improves the precision of the injection molding process, provides difficult process technology, but also expands the scope of the injection molding process.

Anonymous users2024-02-12Two-color injection mold molding requires two-color mold, double-shen section blue color injection molding machine. In the production of injection molding process, the amount of glue of the first color of injection molding needs to be controlled, and the quality of the first product is directly related to the problem of two-color glue. The accuracy of the mold must be guaranteed for two-color products, because the sealing position of the product is directly a one-color product.
The last section of the two-color injection molding machine must be slow in terms of wide lifting and ignition speed. <>
Two-color jasmine is raised like this in summer, and it can also produce bright flowers, and the appearance is very high.
The first step in bread making: stirring the dough.
Dough stirring is kneading. Mixing the dough is the most basic step in the whole bread-making process, and it is the second most important point that determines the success or failure of bread making. For details, please refer to the previous post: How to knead bread dough. >>>More

1. The water content of the adobe is about 8 to 18 percent, because the water content is too little, the plasticity is weak, and it is mostly loose and moist powder granules or wet hard soil blocks, which must be formed by using strong mechanical pressure and steel molding. Its advantages are: mechanical automatic operation and fast production, neat and uniform steel mold forming, less water content of the blank, so the drying shrinkage is small, and the deformation opportunity is also less. >>>More
