Heat shock activated sintering

In 2003, a study conducted by the Dong-Lang Chai Group 6 at Xi'an Jiaotong University focused on the in situ observation of the binary system of pure metal powder sintering process using an Al-10 Mg alloy. The study found that the use of common resistance heating caused fluctuations in the sintering temperature field, which had a thermal oscillation activation effect. This effect significantly improved the melting velocity of magnesium particles in the aluminum matrix. The fluctuations in the temperature field during the sintering process were found to be much shorter compared to

Development trend of shearing type mixer to kneading type mixer

The mixing machine has become the preferred equipment for many rubber and plastic enterprises due to its large mixing capacity and small environmental pollution. As the production and application of mixing machines continue to develop, the mixing mode is transitioning from shearing type to kneading type, and the kneading mixer is gradually gaining acceptance in the industry. In the powder injection molding industry, the kneading mixer plays a crucial role in feed production. Ordinary mixer machines rely on the rotor, sh

Injection molding process personnel must know 18 basic knowledge (13-18)

13)Calculate retention time and importance As a general practice, the residence time of a plastic on a particular injection molding machine should be calculated. Especially when large injection molding machines use less injection volume, the plastic is easy to decompose, and this is not detectable from observation. If the retention time is short, the plastic will not be uniformly plasticized; The properties of the plastic will decay as the retention time increases. So be sure to keep the detention time c

Three factors that affect the fluidity of MIM stainless steel feedstock

Metal injection molding (MIM) is a manufacturing process used to produce small, complex precision metal parts. It involves mixing metal powder with an organic binder to create a feed material, which is then injected into a mold using the same method as plastic injection molding. MIM has gained recognition and is widely used in the production of precision metal parts. The feed material used in MIM, also known as MIM feed, plays a crucial role in the process. It must have the right rheological properties to ensure successful molding. Cur

Plansee simplifies hot zone door operation in metal injection molding furnace

Plansee, an Austrian company, focuses on improving energy efficiency and performance in the hot zone of high-temperature furnaces. They achieve this through proper design and efficient heating elements, resulting in a clean environment and high temperatures. The hot zone also minimizes heat loss by shielding the package. Plansee has specifically worked on the design of MIM thermal doors to enhance their functionality. In many current designs, opening the hot zone door requires two hands and the removal of the actuating mechanism of the valve for rapid cooling. This increases the
