How to make the structural unit of die-casting mold? 1.Forming part The parts that make up the cavity include: fixed and movable inserts and cores. 2. Formwork Various formwork, frame and other structural parts. The function is…
How To Change The Hardness Of Plastics? 1. The concept and representation of hardness Hardness refers to the ability of a material to resist the pressing of other hard objects into its surface. The magnitude of the hardness value is a conditional quantitative representation of the degree of softness and hardness of the material. It…
Three Common Polishing Methods For Precision Stamping Dies There are two main purposes for polishing precision stamping dies. One is to increase the brightness and precision of precision molds. The second is to make the mold easy to demould. In the polishing process, the coarse oil stone is generally used first, and the surface of…
Type Of Cooling In Plastic Extrusion There are two main purposes for polishing precision stamping dies. One is to increase the brightness and precision of precision molds. The second is to make the mold easy to demould. In the polishing process, the coarse oil stone is generally used first, and the surface of the machined…
Analysis Of The Causes Of Mold Failure From the current actual situation, there are five main reasons for mold failure: plastic deformation failure; wear failure; fatigue failure; cold and heat fatigue failure; failure under the influence of comprehensive factors. 1.Plastic deformation failure Mainly because the strength level of the mold material is not high; or…
Filling Time, Holding Pressure And Opening Time Of Die-Cast Products 1.Filling time The time required for the liquid metal to enter the cavity to fill the cavity is called the filling time. The length of filling time depends on the size and complexity of the casting volume. For large and simple castings, the filling time…
Aluminum Alloy Gravity Casting Mold And Use Steps While advanced equipment is an essential factor in ensuring product quality, the role of molds in casting is equally important. Especially for aluminum alloy auto parts manufacturers, the accuracy and durability of the mold have a significant impact on product quality. For ferrous metal casting, the mold…
Mold Manufacturing Requirements For Material Properties For the material performance requirements of mold manufacturing, the details are as follows: 1.Annealing process The spheroidizing annealing temperature range is wide, the annealing hardness is low, the fluctuation range is small, and the spheroidization rate is high. 2. Forgeability It has low hot forging deformation resistance, good plasticity,…
Analysis Of The Ray Line Of The Gate Area Of Injection Molding Products In the point gate design in the vertical part direction, a radiation system composed of different color depths and lusters, which is centered on the gate, is called a ray line. There are three general manifestations, namely dark dark lines, dark lines…
