Can Suzhou double-color injection molding process use the same color material?
Suzhou two-color injection molding process should be how to control the pressure? Suzhou two-color injection molding two important processes are filling and holding pressure, secondly, explain how to control the pressure in the two-color injection molding process.
Suzhou two-color injection moldingHow to control the pressure in the process?
The two important processes of Suzhou two-color injection molding are filling and holding pressure. Secondly, it explains how to control the pressure in the two-color injection molding process.
1. Injection pressure
In the current two-color injection molding production, the injection pressure of most injection molding machines is based on the pressure applied to the plastic from the top of the plunger or screw (converted by the oil pressure). The role of injection pressure in injection molding is to overcome the plastic from The flow resistance of the cylinder to the cavity gives the melt filling speed and compacts the melt.
2. Plasticizing pressure
During injection molding, the size of the plasticizing pressure needs to change according to the design of the screw, product quality requirements, and the type of plastic. If these conditions and the speed of the screw remain unchanged, the plasticizing pressure increases and the shearing effect increases, that is, the temperature of the melt rises., But the efficiency of plasticization is improved.
In addition, increasing the plasticizing pressure can make the melt temperature uniform, the pigment is mixed evenly, and the gas in the melt is discharged. In general operation, the plasticizing pressure is determined to ensure the good quality of the product, the lower the better, and its specific value is used The variety of plastic two-color molding molds varies, but usually rarely exceeds 20kg/cm2.
Suzhou double-color injection molding factory: can double-color molding materials be made of the same material?
Suzhou two-color injection molding material is different from the mold used in two-color molding technology and the usual injection molding mold. Therefore, the use parameters of two-color molding technology materials need to have a high melt temperature before the injection molding is completed. At the same time, the pressure of raw materials is controlled by the injection molding device to achieve the purpose of injection molding. Thus, not all raw materials are suitable for two-color injection molding.
Two-color molding materials generally choose plastics with different colors, which can greatly improve the strength and durability of injection molded products, and also facilitate the molding of injection molded products. However, special-purpose products may be used in situations where the two materials are very different, and this needs to be resolved. The coupling problem between materials.
Another treatment method is to use additives to change the chemical bonding characteristics of non-adhesive materials. For example, PA6 and PP can be bonded by adding maleic anhydride grafted polypropylene.
The allowable amount of the joint interface of the two materials and the length of the melt contact time will affect the bond strength. Therefore, if the material that needs to be processed by two-color injection molding does not meet the requirements of the above table, there is no need to worry, find a suitable additive formulation, one material and The other is closely combined to meet customer requirements.
