What Are The Consequences of Plastic Mould Improper Heat Treatment
Above will not generate large thermal stress and more peace. If mould heating speed and diathermy fast, inside and outside the mold with great thermal stress. If the control is not good,it easily caused the deformation or crack. it is essential in preventing or slowing the rate of temperature increase preheating.

Taking Notice Of Design Aluminum And Aagnesium Alloy Castings Construction
Since the melting point of aluminum and magnesium alloys low, you can use a variety of methods for producing cast aluminum and magnesium alloy castings. Therefore, in the design of their structures, the first of which should be considered in the foundry casting casting method in order to consider the appropriate structure manufacture ability.

How To Reduce Mould Defects In The Manufacturing Process (Point 4-7)
Electrolytic grinding, improve mold manufacturing precision and surface quality . electrolytic grinding wheel scraping the oxide film: instead of grinding metal, thus small grinding force, grinding heat is small, does not produce grinding burrs, cracks, burns and other phenomena, the general surface roughness can be better than Ra0 .16μm; addition , wheel wear is set small, such as grinding carbide, silicon carbide wear large grinding wheel of about 400% to 600% by weight of the carbide off, electrolytic grinding, the grinding wheel wear only the amount of carbide material removal amount of 50% to 100 %. Reasonable choice of grinding parameters, the use of radial feed grinding method even smaller amount of fine grinding. As appropriate to reduce the radial feed rate and wheel speed , increasing the axial feed rate, so that the grinding wheel and the workpiece contact area is reduced , cooling conditions have been improved in order to effectively control the increase of surface temperatures.

The Introducing of Stamping Process
Stamping process and mould design is carried out punch important technical preparations. Stamping process and mould design should be combined with the actual situation of the factory equipment, skills of workers. From the quality of parts, production efficiency, production costs, labor intensity, environmental protection and safety considering all aspects of production, the selection and design of advanced technology, economically rational, safe and reliable technology solutions and mold structure, so stamping production on the basis of the guarantee to meet the design drawings of the proposed technical requirements on the process to minimize costs and ensure safety in production stamping.
