PA66 GF30 Car Parts Plastic Injection Mold If you want to get the product is straight, your mold design and mold processing are also made straight, but there will be a bent product, deformed or the product size is out tolerance, they were caused by material, temperature, shrinkage, and plastic moulding process after the product cooling completely so that we will make the original straight mold into the opposite direction to the deformed product through design analysis and empirical compensation during mold design, then the product will become curved at the beginning, but the product will become straight and in good tolerance after natural cooling. This technique is called mold pre- deformation technology If you want to know more types of Predeformation mold, please visit our website.

The same type of material of different colors is usually used for two-color injection overmolding（or 2k injection molding）so that the bonding strength of the first color and the second color plastic is the best, but due to the functional requirements of the product, the performance difference of the two materials actually used may be very big, if the elastomer is injected into the surface of a rigid material, the most difficult thing to solve during 2k moulding process is the delamination and shedding of the bonding surface of the two materials. OVER-MOULDED 2K MOLDS FOR SALE Water Proof Plastic Enclosure Mold The product will be made by two times, which will inject the second piece after finishing the first piece in the other mold and different injection machine, normally will be no specific request for 2 different pieces injection time, injection machine. Drip Tip Mold The two-color molding will be made in one same injection machine at the same time by 2 times injection, with 2 injection barrels and 2 different injection gates by 2 different molds, but the product will be picked up one time, it will request 2 molds in one specific 2k injection machine to finish final injection. 2K Mold This mold will be put with a movable core on gate position of the core side, the movable core is pushed to the rising position when injecting the first- color material, and the first color part is solidified, After that, the movable core return back through the action of the hydraulic device, at this time, another barrel injects the second color material into the space left by the retreat of the core, the mold is opened and the part is taken out after finishing one injection after it's solid. Material Selection For 2K Plastic Injection Moulding In addition to meeting the requirements of product function and appearance in the material selection of two-color products, whether the adhesion between raw materials can be solved well will be related to the success of two-color products in 2k moulding process is also the difficulty of 2k moulding technology. The following four points should also be considered in the selection of materials for two-color injection molded products: 1. In terms of the effect of the bonding surface, if the force of the bonding surface of the two materials cannot be enhanced by the structure, the bonding performance between the selected materials is better, the material has good adhesion performance, the bonding surface layer has a large force, and it is not easy to delaminate and fall off. 2. In terms of shrinkage rate, if the two-color injection molded product is prevented from falling off and delamination through structural embedding or wrapping, it should be noted that the thermal shrinkage rate of the two materials cannot be too different, and try to match the shrinkage rate completely. Generally, the shrinkage rate of the first color material is slightly smaller. 3. In terms of processing parameters, for the two-color plastic injection overmolding process, because in the 2k injection molding process, although the two injection cycles are relatively independent, the entire injection cycle time is the same, so it is necessary to focus on controlling the injection time of the two-cavity injection cycles, cooling time and pressure holding time, so as to ensure that the product can be produced normally; at the same time, it is also necessary to control the injection volume, injection speed, and mold temperature, this is because in 2k plastic injection moulding, changing the injection volume and mold temperature can make the degree of mixing of the plastic part or the thickness of each layer occur. Change, and whether the injection speed is appropriate or not, will directly affect whether the melt may have turbulent flow or cause the outer layer of the plastic part to rupture during the flow process. 4. In terms of temperature difference, it is necessary to avoid too much temperature difference between the two-component materials. 2K Molding Design Guide Structural design is the most important part of 2k molding product design, the structure design of the product should not only consider the function of the product but also consider whether it meets the processing conditions and the complexity of the processing mold, in the design of two-color injection products, in addition to the issues to be considered for ordinary injection products, the following aspects should also be considered: 1. The quality ratio of the two materials: since the injection time is related to the injection volume, the coordination of time is also related to the product design. To control the injection volume ratio, the difference in the injection quality between the two cavities should not be too big. 2. Product structure shape design: in order to increase the 2k moulding product's fusion strength, the measure in the product structure design is to increase the contact area of the two parts. For example, if possible, the contact area of the two parts can be enlarged through the non-joining surface, and concave and convex grooves can be designed around the small cavity products (which can be generated by forced demolding, and the depth can reach 2mm). As professional 2k molding factory, we will do our best to provide more types of related products for sale, if you have needs, please contact us. As one of injection molding manufacturers, we will do our best to meet all the needs of customers.

Metal Insert Molding Choosing suitable material and molding conditions, not only for products that are easily deformed and damaged (such as glass, coils, electrical parts, etc.), can also be sealed and fixed by material. Choosing a suitable mold structure, the insert product can also be inserted into the plastic material. With the combination of the vertical metal insert plastic injection molding machine, manipulator, and insert part aligning device, most of the insert molding engineering can realize automatic production. After the insert is molded, it can also be made into parts with hollow grooves after core hole processing. Notes Need Attention When Making Metal Insert Part 1. In order to improve the connection firmness of the metal insert and the plastic part, the insert and the plastic part are tightly combined, and the surface of the insert should be knurled or processed with grooves to increase friction force, the insert is not easy to pull out and rotate. 2. The connecting part of the plastic part and the insert should have a suitable thickness to improve the connection strength of the two connecting parts, the selection of the thickness value should be determined according to the properties of the plastic and the shape of the insert, or refer to the empirical value in the table below. 3. The threaded fixing part of the insert and the mold should adopt the H9/f9 threaded fit to avoid melt plastic from entering the non-plastic end of the insert, if not connected with threaded, the H8/h7 sliding fit should be adopted; the insert can be made convex, this can not only block the melted plastic but also increase the stability of the insert and the mold. 4. The parts inserted into the plastic part should be inverted into a circular arc shape to prevent stress concentration in the plastic parts. 5. The length of the insert embedded in the plastic part diameter should not be bigger than 2 times. 6. In order to avoid the insert from damaging the mold cavity, it should be noted that the height of the insert is slightly smaller than the height of the molding cavity of the plastic part, and the difference is about 0.05mm. 7. In order to prevent the metal insert from being pulled out, a ring groove can be placed in the middle of the insert. 8. For externally threaded inserts, a non-threaded area should be provided to prevent molten material from penetrating into the mold. Now the price of products made with injection moulding is affordable, if you have needs, please contact us.
