The burr phenomenon of aluminum alloy is inevitable, and there are many methods to deal with the burr. In the production process of die casting, due to factors such as pressure shock and insufficient clamping force, burrs are inevitable. In recent years, with the increasing quality requirements of die castings, the requirements on burrs have become more stringent, and the methods of deburring have also emerged endlessly. The deburring process is the most troublesome. Today Bengbu Longhua Die Casting Machinery Co., Ltd. recommends the following pros and cons of various types of die casting deburring methods, so that you can better understand the various deburring methods and according to your needs Select the appropriate deburring method. 1. Artificial deburring  This is the most traditional and commonly used method in the die-casting factory. It uses files (files include manual files and pneumatic files), sandpaper, belt machines, grinding heads, etc. Disadvantages: labor costs are expensive, efficiency is not very high, and complex cross holes are difficult to remove. Applicable object: The technical requirements of workers are not very high, applicable to aluminum alloy die castings with small burrs and simple product structure. 2.Die deburring   Deburring is performed by using a production die and a punch. Disadvantages: Requires a certain die (rough die + fine die) production cost, and may also need to make a shaping die. Applicable object: It is suitable for aluminum alloy die-casting parts with relatively simple parting surface, which has better efficiency and deburring effect than artificial. 3.Grinding and deburring  This type of deburring includes vibration, sand blasting, rollers and other methods, which are currently used in die casting plants. Disadvantages: There is a problem that the removal is not very clean. It may require subsequent manual treatment of residual burrs or deburring with other methods. Applicable object: Suitable for small aluminum alloy die-castings with larger batches. 4, frozen deburring  The burr is quickly brittled by cooling, and then the projectile is ejected to remove the burr. The price of the equipment is about two to three hundred thousand;  Applicable object: Suitable for aluminum alloy die-casting with smaller burr wall thickness and smaller volume. 5, hot deburring  Also called thermal deburring, explosion deburring. By passing some easy gas into an equipment furnace, and then using some media and conditions to make the gas explode instantly, use the energy generated by the explosion to dissolve and remove burrs.  Disadvantages: expensive equipment (prices of millions), high operating technology requirements, low efficiency, side effects (rust, deformation);  Applicable object: mainly used in some high-precision parts and components, such as automotive and aerospace and other precision parts. 6.Deburring of engraving machine  The equipment ...

Sometimes, the surface of the die casting has a network of hair-like raised or sunken marks, as the number of die-casting increase and can not be expanded and extended.Visual recognition, hand touch surface and rough. Causes: 1, die casting mold cavity surface crack 2. The used die casting mold material is improper or the heat treatment process is incorrect 3. The temperature difference between cold and heat of the mold changes too much in a very short time 4. Casting temperature is too high 5. Uneven and insufficient preheating before mold production 6. Rough surface of mold cavity To improve the method 1. Correct selection of mold materials and heat treatment process Longhua die casting machine adopts H13 hot die steel, which is resistant to high temperature, corrosion and easy to maintain to ensure casting quality. 2. Casting temperature should not be too high, especially for alloys with high melting point.In order to meet the production demand, the casting temperature should be as low as possible 3. Preheat the mold sufficiently and evenly. Longhua die-casting machine suggests that before the use of the mold, use liquefied gas or natural gas concentrated baking 3-5 minutes, to ensure that the mold fully uniform preheat, improve the surface problems of the die casting. 4, mold production to a certain number of annealing, to eliminate the internal stress. Longhua die-casting machine suggests that you, after each use, timely remove the impurities in the mold cavity, smear lubricating oil to maintain the mold, prolong the service life of the mold. 5. The surface of runner and cavity is not regularly polished to ensure the surface of the mold is clean 6, reasonable choice of mold cooling method, to ensure the mold heat balance

Musk has revealed that Tesla is trying to use Model Aluminum to build the Model Y's body, rather than a mix of stamped steel and aluminum, so that batch automated production can be faster. In this way, we can build some large casting machines and turn 70 body parts into one, greatly reducing the design and expenditure of the assembly robot. Tesla described the current problems in vehicle die casting: "Generally, during the production and die casting of frames, different die casting machines require different die casting machines. For example, a single die casting machine in a factory It is used to die-cast a single frame component. Then, a factory worker or a robot system will assemble or fix the components casted by each die-casting machine (such as by welding) to form a frame (such as an integrated frame). For other casting and production processes that assemble other individual components (such as due to the high cost of casting equipment and metal molds), the die casting process usually requires high costs, so it is necessary to improve the die casting machine and related die casting methods, especially to reduce the final Assembled into a frame of die-casting work. "Tesla proposed a system that allows several molds to converge in one center. According to the patent application, the system was designed by Matt Kallas, Tesla's "mold manufacturing director," and Matt Kallas left Tesla to become a die-casting mold designer for GF Linamar. The patent states: "The multi-directional die casting machine configured according to the current frame includes a mold with a car cover and several punches that can be translated relative to the cover mold. These punches are moved to the casting machine respectively. The central casting area is responsible for casting different Parts and do most of the frame casting work on one machine. "Tesla believes this design can" reduce production time, operating costs, production costs, factory floor space, factory operating costs, tool costs, and number of equipment. In addition, Tesla even said that it can reduce the number of casting machines that produce frames and produce "completely or partially completed" frames on its own. According to reports, the patent was designed by Matt Callas, Tesla's "mold manufacturing director." He held the job at Tesla for a long time, but later left Tesla and switched to General Motors to continue his car foundry work. It is reported that this patent was designed by Matt Kallas, Tesla's "mold manufacturing director". He had long held this job at Tesla, but later left Tesla and switched to General Motors to continue his work in vehicle foundry. At present, Tesla has high hopes for this new type of casting machine.

Recently, the Ministry of Industry and Information Technology announced that 5G commercial use has officially started! The development of 5G puts new demands on network infrastructure. The number and cost of base stations are more than twice that of 4G. It takes about seven years to build 6 million 5G base stations in the country. Costs will reach unprecedented heights. In the manufacture of 5G terminals, 5G mobile phones and 5G terminals will be launched on a large scale. The "China 5G Economic Report 2020" released in Beijing shows that 5G commercial use will drive 900 billion yuan in investment in China in 2020, and 1.5 trillion yuan in 2025. According to reports, the five pioneer industries of mobile terminal, automotive industry, industrial Internet, medical health, and pan-entertainment will take the lead to benefit from 5G. The high demand for 5G base stations and filters has also driven the development of die-casting suppliers in its industry chain, such as filter cavities and base station heat sinks. The difficulty of filter design and the substantial increase in the number of filters are an inevitable trend, and their corresponding value and sales will double.
