How to Control the Temperature of Zinc Alloy Die Casting Molding?

The temperature control of zinc alloy die casting molding is very critical, because the temperature has a great impact on the moliding quality and performance of the casting. The following are some methods to control the temperature of zinc alloy die casting: 1. Control melting temperature: The melting point of zinc alloy is low, generally around 380 ° C, so it is very important to control the melting temperature. It is usually recommended to control the melting temperature between 390 ° C and 420 ° C to ensure that the zinc alloy can be fully melted and the temperature is not too high. 2. Control mold temperature: The temperature of the mold also has a great impact on the quality and performance of the molding. It is usually recommended to preheat the mold to more than 200 ° C, and control the temperature of the mold through water cooling during the production process to ensure molding quality and production efficiency.
3. Control zinc alloy injection temperature: Zinc alloy injection temperature should be the same or slightly lower than the melting temperature to avoid defects such as pores and scars on the surface of the casting. 4. Control injection time and pressure: Injection time and pressure are also important factors affecting the quality of zinc alloy die casting. It is usually recommended to adjust the injection time and pressure according to the specific casting requirements to ensure the density and surface finish of the casting. To sum up, controlling the temperature of zinc alloy die casting molding needs to consider a number of factors, and conduct comprehensive management and monitoring to ensure the molding quality and performance of the casting.

How does a CNC machining center ensure precision for mass-produced products?

Precision is one of the most important indicators to evaluate the processing performance of a CNC machining center . The processing precision and processing errors have a great impact on the quality of the processed parts. How can a CNC machining center ensure the precision of mass-produced products? The most commonly used processing method in the CNC machining industry is the trial cutting method. The trial cutting method is to try cutting, measure the size, adjust the cutting depth of the tool, cut again, and repeat the process until the required size is achieved. This method can ensure that the error is within a reasonable control range, but it is quite cumbersome and has a low production efficiency. It is mainly used for single-piece and small batch production. In mass automated production, CNC machining centers can achieve the required size by adjusting the relative positions of the machine tool, fixture, workpiece, and cutting tool in advance, thus achieving the goal of ensuring

How to deal with the plastic injection molding raw material is not filled?

图片
Electric injection molding machine in the production of injection mold will encounter the situation of injection molding is not filled, there is a lack of glue at the bone position right Angle and fuse connection, here to share some experience. Analysis of glue injection is not filled: 1. The trapped air in the bone position makes the injection molding machine fill up. 2. The filling of the injection molding machine caused by the glue welding line is not filled. Reason analysis of glue injection is not filled: When the injection molding machine is working, the mold gluing method is two-point gluing, and the injection speed is too fast, which is easy to cause the gas trapped at the right Angle of the bone position and cause the filling dissatisfaction; If the injection speed is too slow, it is easy to fill the fuse at the end of the flow. The solution: Multistage injection molding and position switching. In the first stage, the medium speed filling channel was used to pass

Control of Injection Molding Parts Processing Temperature

图片
There are many kinds of plastic, many plastic materials melting time are different, because the plastic does not have a specific melting point, the so-called melting point is a melting state of the temperature segment, the structure and composition of the plastic molecular chain is different, so the impact on its fluidity is also different, then in the production of injection parts manufacturers in the injection parts processing temperature control is also very important. 1. Mold temperature Some plastic materials due to high crystallization temperature, slow crystallization speed, need higher mold temperature, some due to control size and deformation, or the need for demoulding, to higher temperature or lower temperature, such as PC generally requires more than 60 degrees, and PPS in order to achieve a better appearance and improve fluidity, mold temperature sometimes needs more than 160 degrees, Therefore, the mold temperature has an inestimable effect on improving the appearanc
