      What Is Die-Cast Housing?

      A die-cast enclosure is a metal enclosure that has been made by the die casting process to house internal parts like motors, eletrônicos, engrenagens, or sensors. These housings are used to support the mechanical, ambiental, dissipação de calor, and electromagnetic shielding, based on the application.

      One of the most common uses of die-cast housings is that they are very strong, have a high quality of surfaces and repeatability, and are suitable for both functional and aesthetic assemblies.

        How Does Our Die-Cast Housing Work?

        Na TOPS Precision, machine housings are die-cast entities that are made to high precision employing a carefully regulated manufacturing procedure that ensures the accuracy, força, and repeatability across the entire concept to the final part.

        1. Design Evaluation & Ferramentas

        No TOPS, all die-cast housing projects have a customer drawing and specification review. Our engineers study the design in terms of manufacturability, estrutura, e eficiência de custos, and create precision steel molds with light geometry, maximum flow of materials, and long life of the tools.

        2. Metal Injection

        When tooling is finished, high-pressure pressure is applied to high amounts of molten aluminum, zinco, or magnesium alloy into the steel die. This ensures that the metal moves into fill complicated cavity structures within a brief time span in an even infiltration, resulting in housings that have fine detail, paredes finas, and high dimensions of accuracy.

        3. Resfriamento & Ejeção

        The injected molten metal rapidly solidifies in the mold. The completed housing is then ejected in constant shape and structure to allow reproducible quality and little distortion between production batches.

        4. Trimming & Usinagem CNC

        Runners and flash material are trimmed, and such important elements as mounting holes, superfícies de vedação, and interfaces are CNC machined to close tolerances and rigorous functional activity.

        5. Surface Finishing/ Inspection

        Anodização, revestimento em pó, or polishing of the surface is done to increase the durability and the surface appearance. All housing is then inspected to a great extent to ensure that its dimensions, qualidade da superfície, and general adherence to specifications are accurate.

              Techniques of Die-Cast Housing

              TOPS meets complex design and performance needs by applying sophisticated die casting processes. They guarantee high structural integrity, precisão, and efficiency in productions.

              1. Fundição sob pressão de alta pressão (HPDC)

              HPDC allows the die-cast housings to have clean edges, detalhes finos, and high consistency in dimensions; hence, it is suitable for high-volume and complicated applications.

              2. Fundição sob pressão a vácuo

              Vacuum die casting eliminates air pockets in the design, greatly decreasing porosity and forging heavier, tougher housings that are suitable for harsh structural or pressure-sensitive environments.

              3. Thin-Wall Die Casting

              Thin-wall die casting enables hollow objects to be created with less material but with the same structural integrity, to help in reducing the weight without damaging the strength.

              4. Automated Die Casting Cells

              Automated production cells combine robotics and real-time feedback to maintain uniform quality, more efficiency, and constant production output over high volumes of production.

                5 Die-cast Housing Cost-Saving Tips.

                The use of smart design and manufacturing choices is the beginning of good cost control in the production of die-cast housing. The following tips can be used to minimize the costs of tooling, material, and production without any loss of quality and performance.

                • Design Housing Early: Baffle off undue thickness and complication.
                • Select the Right Alloy: Adapt material performance to application requirements.
                • Reduce Secondary Machining: Design near-net-shape housings wherever feasible.
                • Standardize Features: Tooling cost is minimized by common hole sizes and wall thickness.
                • Select an Integrating Manufacturer: One-stop production reduces lead time and logistics.
