Die Casting Communication Equipment Parts

LPDC, or low pressure die casting, fills the die from the bottom using controlled gas pressure, which reduces turbulence and porosity. GDC, or gravity die casting, relies on gravity to fill the mold and is often better for thicker-walled parts and medium-volume runs. For communication equipment parts, LPDC is typically preferred when density, strength, and internal soundness are critical.

A die casting setup typically includes the die or mold, casting machine, shot chamber, plunger or injection system, furnace or molten metal supply, ejector system, cooling channels, and trimming or finishing operations. In a production environment like Marcus, the process also includes tooling design, CNC machining, inspection, and surface treatment to deliver finished communication equipment parts.

LPDC works by applying low inert gas pressure beneath molten metal, forcing it upward through a riser tube into the die cavity. Because the metal fills from the bottom in a controlled way, the process minimizes oxide formation and trapped air. This produces denser castings with better mechanical properties, making LPDC suitable for structural aluminium communication components.

The best process depends on the alloy, geometry, wall thickness, and production volume. Hot chamber die casting is often used for small, high-volume zinc parts such as connector bodies and compact housings. Cold chamber die casting suits aluminium and magnesium components with tighter structural requirements. LPDC is a strong option for larger aluminium parts where low porosity and improved strength are important.

Communication equipment parts are commonly produced in aluminium, zinc, and sometimes magnesium, depending on weight, strength, shielding, and finish requirements. Marcus supports alloys such as ADC10, ADC12, A380, A384, LM series aluminium grades, A356, A357, and Zamak alloys. Material selection is usually based on dimensional needs, corrosion resistance, thermal performance, and downstream machining or finishing requirements.

Yes. Marcus provides in-house CNC machining and surface finishing to turn castings into production-ready components. Machining can add critical bores, threads, sealing faces, and precision mating features, while finishing options include anodising, plating, powder coating, blasting, and other treatments. This integrated approach improves quality control, shortens lead times, and reduces the need for multiple outside suppliers.

Quality requirements typically include dimensional accuracy, surface finish, material consistency, and process traceability. Marcus operates under IATF 16949:2016 and ISO 9001 certified systems and applies structured controls such as DFM, APQP, PPAP, FAIR, inline inspection, and advanced metrology. Depending on the part, additional checks may include coating thickness verification, salt spray testing, and functional inspection after machining or assembly.

Yes. Marcus supports both early-stage development and scaled OEM production through in-house tooling, rapid prototyping support, trial validation, machining, and semi-automated assembly capabilities. This allows customers to move from design review and T0 or T1 trials into repeatable production with the same manufacturing partner. It is especially useful for communication equipment programs that need controlled ramp-up and consistent quality.
