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…
DetailsAnalysis 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…
DetailsFilling 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…
DetailsAluminum 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…
DetailsMold 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,…
DetailsAnalysis 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…
DetailsHow Does The Die-Casting Mold Improve The Damage Caused By Stress? Stresses include thermal stresses and mechanical stresses, mainly due to mechanical, chemical, and operational shocks. Heat is specifically produced in the following ways. 1. In the process of die casting production (1) The cooling temperature control system should be set to keep the working…
DetailsHow To Improve The Flexibility Of Plastics? Intuitively, the flexibility of plastic refers to the softness of plastic products, that is, the softer the plastic products, the better the flexibility. In polymer physics, flexibility is defined as the property of a polymer chain to change its uniformity. The flexibility of a plastic depends on the…
DetailsHow To Reduce The Density Of Plastics? Reducing the density of plastics means that the relative density of the plastics is reduced by appropriate means to suit the needs of different applications. The methods for reducing the density of plastics include foaming modification, adding lightweight fillers, and blending lightweight resins. 1. Foaming modification Foam molding…
DetailsSix Development Directions Of Mold Design 1. Material selection The greenness of the mold material has a very important impact on the green performance of the final product. The choice of materials for green design must be based on green materials, abandoning the chemical methods used to surface the materials in the past, and replacing…
