Focus on benefits

 

We have established our successful brand based on the quality and reliability of the equipment. We are customer-centric, combine theory and practice, and establish a complete sales network and convenient after-sales service. In our application of efficiency and economy to project work, design, materials and processes, as well as calculation and control technology, this is our strength.

 

 

Own heat treatment center for process development and testing

 

From laboratory test results to large-scale production, this is not a simple multiplication problem, because a suitable test-run equipment is relatively expensive and requires many parameters. In order to accurately obtain various parameters for production, 2019 We established a heat treatment center at the beginning of the year.

In this way, we can carry out small series production, process development, sampling, and if necessary, we can also find out how to seamlessly transition to large-scale product production. In this way, project operations can be carried out more efficiently and economically, even for demanding projects.

SPS/Hot press Q&A on sintering test

 

Q: Can insulation also be sintered?

A: There are many sintering examples such as oxide ceramics, carbide ceramics and nitride ceramics.

 

Q: What is the material of sintering element?

A: Graphite type (isotropic graphite) is generally used. In addition, C / C composites, superhard alloy and high temperature die steel are also used.

 

Q: Can porous bodies be sintered?

A: Although it depends on the particle size of the powder, the sintered body with a certain opening can be made. In addition, the closed pore structure can also be made by using the powder mixed with foaming agent and heat treatment after sintering.

 

Q: What is the furnace atmosphere in sintering?

A: Sintering is usually carried out in a vacuum atmosphere of about a few PA. Sintering in inert gas (argon or nitrogen) is also possible, but the gas pressure of sintering in inert gas atmosphere is below atmospheric pressure. In addition, in order to protect the sintering type, it is suggested that the sintering temperature should be below 400 ℃.

 

Q: What is the temperature measurement method in sintering?

A: When the sintering temperature is below 1000 ℃, a seamless thermocouple is used to measure the internal temperature of about 5mm from the periphery of the sintering type as the target of sintering temperature. When the sintering temperature exceeds 1000 ℃, infrared radiation thermometer is used to measure the temperature of the peripheral part of the sintering type from the vacuum chamber observation window.

 

Q: What are the goals for the progress and completion of sintering?

A: Generally, with the increase of sintering temperature, the sintered samples begin to shrink. Taking the shrinkage as displacement, the sintering end can be judged according to the sintering temperature and displacement state

 

Q: What is the application procedure for sintering test?

A: Please feel free to contact us on the "consultation" page or telephone number of our company or via email: sales@haoyue-group.com Contact us, please fill in the process information as much as possible in this "processing content book" and email to us.

 

Q: What is the cost of sintering test?

A: The rating varies depending on the sintering plant used, but the daily quota is the same. Depending on the size of the sinter and the sintering conditions, the quantity of production per day (about 8 hours) varies. In addition, the cost of sintering type and sintering accessory materials should be borne separately. First of all, please feel free to consult.

 

Q: Can site operation of sintering test be carried out?

A:Sintering test can be carried out.

 

Q: Can carry out a few ~ dozens of commission processing every month?

A:We will discuss according to the sintered products, please feel free to consult.

 

Q: What is the implementation period of sintering test?

A:It usually takes about 2-4 weeks if the sintering type (φ 5-30, 2-10 inch) can be used
