Same as mentioned in the video above: SHENZHEN CAMEL DIE LIMITED, We have a company named CAMEL Because it is very suitable for the mold industry - “stable, like a CAMEL!" Good quality and lead time both are our advantages, and receive good reputation from many clients in the past 10 years. We export many tools to western Europe and North America every year. Here are 2 floors and 5,000 m2 for molds building only and 45 people as 2 shifts from Monday to Saturday. Last but not least, I hope my introduction can help you know more about CAMEL.

Abstract: High-pressure die casting is an important process for forming non-ferrous metal structures. The production elements of die casting are composed of a die casting machine, die casting mold, die-casting process, and die casting alloy. Low speed (hereinafter referred to as low-speed) is one of the key parameters of the die casting process. The low-speed setting has a more important effect on the quality of die-casting parts. This article will verify the impact of the low speed of die casting on the quality of parts while ensuring other parameters are not changed. Keywords: Die casting process; Low speed; Die casting parts. 1.Filling effect of casting at low pressure of 0.2m/s Figure 1.1  The filling state of the low-speed 0.2m/s shot sleeve ①  The filling of aluminum liquid is relatively stable, and no obvious entrained air is seen. Figure 1.2   Temperature distribution after low-speed 0.2m / s castings is filled. ② The overall temperature of the casting is about 570°C, which is slightly lower than the liquidus line of the A380 material at 574.4°C. The risk of defects such as the cold lab and flow marks on the surface is higher. Figure 1.3   Entrained air volume fraction after low-speed 0.2m / s casting is filled. ③ Entrained air is basically discharged into the overflow, and the risk of defects such as porosity and surface bubbles in the casting is low. 2.Filling effect of casting at low-speed 0.3m/s Figure 2.1   Filling state of the low-speed 0.3m/s shot sleeve. ① Molten aluminum filling smoothly, and no turbulence is seen, but the molten aluminum at the end of the die-casting is significantly lower than that at the front end, a local entrained air phenomenon is caused. Figure 2.2   Temperature distribution after low-speed 0.3m/s casting is filled ② The temperature distribution of the filled casting is shown in Figure 2.2. The overall temperature of the casting is about 590°C, which is slightly higher than the liquidus line of the A380 material at 574.4°C. The risk of defects such as cold lab and surface flow marks on the casting is low. Figure 2.3     Entrained air volume fraction after low-speed 0.3m/s casting is filled. ③Entrained air volume fraction of filled casting is shown in Figure 2.3. During the casting filling process, a small part of the entrained air remains in the casting area, and the casting has the risk of forming pores and bubbles. 3.Filling effect of casting at low pressure 0.5m/s. Figure 3.1   Filling state of the low-pressure 0.5m/s shot chamber ① The molten aluminum in the shot chamber is shown in Figure 3.1. The aluminum liquid filling the shot chamber stably, but the turbulence phenomenon occurs as soon as the aluminum liquid enters the runner, and the entrained air phenomenon is serious. Figure 3.2   Temperature distribution after low-speed 0.5m/s castings are filled ② The temperature distribution of the filled casting is shown in Figure 3.2. The overall temperature of the casting is about 610°C, which is higher than the liquidus line of A380 material at 574.4°C. With no defects such as cold lab and surface flow marks. Figure 3.3   Entrained air volume fraction after low-speed 0.3m/s casting is filled ③ The distribution of Entrained air volume fraction after the casting is filled is shown in Figure 3.3. There is more entrained air in the casting area during the filling process, with a higher risk of defects such as pores and bubbles. 4.Conclusion ①.The slower the low-speed, the less the volume of entrained air, but too low speed will reduce the temperature of the molten aluminum, and the casting will have problems occur such as cold lab and flow mark. ②.When the low-speed is too fast, the filling temperature of the casting is high, and the possibility of cold lab and flow marks is less, but the volume of entrained air will increase, and defects such as porosity and bubbles will appear. ③.To set the low speed, you must first determine the product requirements. If the casting is an appearance part, you can appropriately increase the low speed to avoid surface defects such as surface flow mark and cold lap to improve the surface molding quality. If the casting is air-tight, it is necessary to reduce the low speed as much as possible to ensure that the casting does not form a cold lap to achieve the best venting effect and ensure the casting sealing performance. 5.

With a background of a profound understanding of the requirements of export quality molds to European and North American companies, and the observation of frustration which takes place when overseas purchasers encounter failure from negative experiences working with unprofessional suppliers in the south of China, as well as when quality did not match with pricing, projects being delayed, poor communication in English, lost contracts with suppliers, etc., CAMEL Engineering was born. Since 2009, Simon and Leo - as founders who established CAMEL Engineering as a professional engineering company in Hongkong and work place in Shenzhen city - have only one purpose, which is to provide international buyers the best engineering service for export molds without misunderstandings of the standards of mold making, and to offer the best quality and excellent lead time. The world financial crisis still affected many local companies seriously in 2009, causing the majority of their business to be reduced over 50-60%. Even more, some factories had to shut down in 3 months to avoid a cash flow break in this “economic winter”. During this time most customers slowed down their projects’ development, as it seems like everybody was waiting anxiously for the “spring” to arrive. CAMEL was not thinking of ideas to control operating costs like the other companies were, but rather stayed busy with improving and upgrading its own project management system and how to offer better service. We believe that opportunities always exist and favor the prepared company. CAMEL’s business was not affected too much during this time, not only because of good luck but also because our workers deeply realized the critical situation we were in and dared not to slack off in communication, manufacturing, and lead time, while doing our best to provide more solutions and analysis for uncompleted projects, supporting customers to win more trust from our hard work, etc. Finally, more and more projects commenced and were delivered successfully to different countries. In 2012, CAMEL invested 60% in one of the biggest mold suppliers in South China, aiming to take the opportunity to focus on the automotive, lighting, and communication industries, working more closely with some larger companies and stepping forward one step at a time to the big development of our company. Two years later, CAMEL was able to take over 100% of the shares and management in this mold shop and subsequently moved to the second location in Dongguan, China. In 2017, CNC quantities increased from 5 to 9 sets and we became an ISO certificated company. At that time, we had 60 workers, including 6 professional mold designers and 32 skilled mold operating workers. Certain of our long-time customers have kept working with CAMEL since 2009, and they became the most valuable assets for CAMEL’s growth. Staying focused on each step is still the working philosophy of our company - focusing on more professional investments in our project management system, employee internal training system, and customer service system. Any one of these areas determines the growth of CAMEL and our customers’ success. CAMEL considers these as a stable iron triangle, not afraid of any difficulties and the belief that the most brilliant future is within our reach, one step at a time.
