What are the challenges of the metal powder injection molding industry?

Powder metallurgy has a series of characteristics in technology and economy. Powder metallurgy is not only a material manufacturing technology, but also a material processing technology. For material manufacturing, powder metallurgy can produce materials with special properties that cannot be produced by ordinary melting and casting methods: it can control the porosity of materials and products, so what are the challenges of metal powder injection molding industry? Let's take a look.

1. Metal powder raw materials

Because of the relationship between quality and quantity, domestic metal powder has never been able to break through. This must be combined with the domestic MIM industry and schools to work together to make metal powder with stable quality and large quantities. I think the key is to understand that metal powder for MIM and traditional metal powder for PM are very different. This point must emphasize the research and development of powder science, and also refueling!

2. Powder and injection system

Similarly, the domestic MIM industry lacks the development of this part. From powder selection and material system fine-tuning, bonding aids and so on, the development of the preceding technology needs to be strengthened.

3. Technical equipment

Fortunately, at present, the equipment level in the mainland has improved rapidly: for example, the vacuum sintering furnace of Ningbo Hengpu has reached the international level and exceeded some of the production capacity, although it can not reach the output of Kramer continuous furnace in Germany, However, as far as the processing capacity and stability of the products in the mainland are concerned, they can fully meet the demand of the order: the injection machines produced by Qingdao Genyilong Machinery Co., Ltd. are also highly professional. Several key parameters have reached the professional level of Aberg and Barton, and the overall use condition is also satisfactory, which is worthy of pride! In addition, the same is true for catalytic degreasing furnace. From nothing to exist and even to unify the world; All these fully prove that the equipment level of the mainland is only higher than that of Taiwan.

4. Technical training of talents

There is a shortage of domestic talents in material science. There are not enough professional departments and students to invest in the early stage of the industry (powder blending and injection system development). Interestingly, there are many talents in the later stage (from mold design to post-processing), but the ability to internationalize is insufficient. The ability to use three foreign languages (English, Japanese, German, English are many customers, Japanese and German are many raw materials and equipment) is weak. This is a project to be added by the country in cultivating talents. I think that the powder injection molding industry actually needs more graduates from the Department of Applied Materials Science to join.

5. Technology sharing

Chinese Kung Fu is extensive and profound, but unfortunately it is lost! This is the regret of the Chinese nation all the time. Fortunately, China has always been tolerant and receptive. For the MIM industry, we hope that all enterprises can share this hard-earned technology. Commercial competition is inevitable, but there must be exchanges in the competition. To participate in this meeting is also a kind of exchange, exchange of ideas and avoid mistakes. We hope that the MIM-CN alliance will share better and more appropriate on the premise of improving industrial technology With the information, we look forward to working together!

6. The challenge of price cutting competition

If metal powder injection molding products fall into price cutting competition and are compared with die-casting and forging, the opportunities and profits brought by this technology to the company will be lost. So it is suggested that how to reduce the price cutting competition opportunities through platform recognition? Of course, the technology and equipment should be good enough, and the requirements of customers should be accurate. Take the order of the American market for example, the smaller the powder injection molding product (the lighter the weight), the higher the price/weight ratio is required, especially the more complex shape, such as flat For products with high tortuosity, such as 3D, molds need multi-directional sliders and diagonal pins. Of course, the order quantity will involve the price. But readers must understand that if the powder injection molding industry does not have a gross profit of more than 20% (before tax), it will not support us to pay high equipment amortization, expensive powder inventory and the driving force of technology development. We hope that through the strength of the MIM-CN alliance, we can coordinate the consistency of the quotation level between factories and avoid price cutting competition!
