    Common problems of die casting die

    Common problem It is very important to control the surface temperature of die casting mold for producing high quality die casting. Uneven or inappropriate die casting mold temperature will also lead to casting size instability, casting deformation in the production process, resulting in thermal pressure, sticky mold, surface depression, shrinkage holes and hot bubbles and other defects. When the mold temperature difference is large, the variables in the production cycle, such as filling time, cooling time and spraying time, will have different degrees of influence. 1). Cold lines:Reason: the temperature of the front of the melting soup is too low,…

    3D printing changes the way manufacturing costs are calculated

    In the traditional sense, the more complex the shape of the goods, the higher the manufacturing cost, which is undoubtedly a large expenditure for enterprises. However, with the widespread application of 3D printers, the complexity of items will no longer be directly proportional to the cost. No matter how complex the shape of the manufactured goods is, the 3D printer can be easily solved without increasing the cost, because there is no relationship between 3D printing complex goods and printing a simple goods. The cost of 3D printing is only calculated according to the material cost, time cost and machine…

    New technology may improve 3D printing process for glass

    Of all the materials that can be 3D printed, glass remains one of the most challenging. However, scientists at the ETH Zurich research centre in Switzerland are working to change this with a new and better technology for printing glass. Printing glass objects is now possible and the most common methods involve either extruding molten glass, or selectively sintering (laser heating) ceramic powder to convert it into glass. The former requires high temperatures and therefore heat-resistant equipment, while the latter does not allow for the production of particularly complex objects.ETH’s new technology aims to improve on both of these disadvantages….

    Ways to control the temperature of your 3D printer

    1. Heat transfer The print head of a 3D printer has two types of heat transfer: heat conduction and heat convection. During the printing process, the solid print material is heated into a liquid by the heating cavity to maintain a molten state with good adhesion mobility, proper filament width and good adhesion properties to ensure the quality of the specimen, i.e. the heat transfer process. In order for the printing process to be completed smoothly and the specimen to meet standards, the heating chamber temperature needs to be kept at a constant temperature in order to avoid being too…
