The resin will release or absorb a certain amount of heat during the curing process, and the degree of the resin polycondensation reaction can be judged according to the heat release, so as to provide

Yz27 stretch hydraulic press--Zhengxi hydraulic model is suitable for all deep and shallow stretching processes, especially suitable for all kinds of containers, various automobile covering parts, hou

It refers to the heat preservation time under the molding pressure and molding temperature. Its function is to make the product solidify completely and eliminate internal stress. The length of the hea

In slow molding, after the heat preservation is over, the temperature must be gradually lowered under a certain pressure, and the mold release operation can only be performed when the mold temperature

Advantages of four-column hydraulic press l The equipment is portable and the customized range can be customized 1-5000 tons l Wide visual space during operation l The equipment is more economical and

Molding pressure refers to the pressure on the horizontal projected area of the product. Its function is to overcome the vapor pressure generated by the volatiles in the material, avoid the defects of

Powder metallurgy (Powder metallurgy, referred to as PM) is a metallurgical process technology that uses metal powder (or a mixture of metal powder and non-metal powder) as a raw material to make meta

Forming is an important step in the powder metallurgy process. The purpose of forming is to produce a compact with a certain shape, size, density and strength. Powder compression molding is the most b

Suppressing force has a direct effect on density. The existing pressure drop causes delamination and peeling during pressing, and cracks exist at the interface of the compact after demolding.

1 The design uses FULL CAD engineering drawings to meet the 2D or 3D design of high-quality punches that meet customer specifications and approval requirements 2 Cutting is carried out according to th

In the pressing process, there must be an appropriate holding time under the maximum pressing pressure, which can significantly increase the density of the green compact.
